The ivory-billed woodpecker has been missing for so long, and rediscovered so often, that the science of how to declare a species extinct has been partly rewritten around it. Below: what we actually know in 2026, why the U.S. Fish and Wildlife Service’s 2021 extinction proposal was withdrawn, and where the long, strange story of Campephilus principalis stands now.

The basic facts

The ivory-billed woodpecker (Campephilus principalis) is — or was — the largest woodpecker species north of Mexico, and one of the largest in the world. About 50 cm long, with a striking black-and-white plumage, a brilliant red crest in males, and the heavy ivory-coloured bill that gave the species its name. The species inhabited mature bottomland hardwood swamp forests across the southeastern United States, with a separate sub-species in Cuba.

The species’ habitat — old-growth Southern bottomland forest, with the standing dead trees its foraging biology required — was systematically logged across the late 19th and early 20th centuries. By the 1930s, the population was estimated at fewer than two dozen pairs, all in remnant tracts in Louisiana, Florida, and South Carolina. By the 1940s, the species was widely presumed lost. By the 1960s, it was being treated as extinct in most ornithological literature. By the 1990s, it was a folk-tale species for U.S. birders — the ghost bird, the Lord-God-Bird, the species you would never see.

The long history of “rediscovery”

The species has been “rediscovered” at least four times since 1944, depending on what counts as a rediscovery. Each cycle has followed a similar pattern: a credible-seeming sighting by an experienced observer, an organised search, a flurry of confirmations, then years of failure to produce definitive evidence (a clear photograph, a recording, a recovered feather), then a quiet retreat.

1944 — Mary Kuhn and others, Singer Tract, Louisiana

The last universally-accepted ivory-billed woodpecker sightings. The Singer Tract was logged in the 1940s, the species was presumed lost from that location, and from there the record becomes contested.

1971 — George Lowery’s photographs

The Louisiana State University ornithologist George Lowery presented two photographs purported to show ivory-billed woodpeckers in Louisiana. The photographs were never definitively confirmed; the species’ status remained ambiguous.

2004–2005 — Big Woods of Arkansas

The most famous of the modern rediscoveries. A team led by Cornell Lab of Ornithology and the Nature Conservancy reported multiple sightings and produced a brief, contested video clip. Science published the announcement. The bird community split into believers and skeptics; subsequent intensive searches (camera arrays, acoustic monitoring, human observers) failed to produce a single unambiguous photograph or video. The Cornell team’s interpretation of the original 2004 video has been formally challenged in peer-reviewed work.

2006 onward — Florida, Louisiana, Texas, repeatedly

Multiple subsequent expeditions have produced sounds-like reports and brief sightings without producing the kind of evidence — clear, undisputed, repeatable — that would settle the matter.

The 2021 USFWS extinction proposal

In September 2021, the U.S. Fish and Wildlife Service formally proposed delisting the ivory-billed woodpecker from the Endangered Species Act on the grounds that the species was extinct. The proposal triggered an unusual public-comment period and a small forest of submitted “we have new evidence” replies.

In July 2024, the agency formally withdrew the extinction proposal — citing newly-presented acoustic and visual evidence from southern Louisiana that, while not conclusive, was “sufficient to warrant continued investigation.” The species’ ESA listing as Endangered remains in place. The withdrawn proposal is not a finding of survival; it is a finding of insufficient certainty to declare extinction.

This is, in its way, the modern history of the species in three sentences.

What the recent evidence actually is

The strongest body of post-2020 evidence comes from a multi-year study by the National Aviary, Project Coyote, and several independent ornithologists, working in southern Louisiana. The team published a 2023 paper in Ecology and Evolution presenting:

• Multiple drone-based aerial videos showing large pied woodpeckers consistent with C. principalis
• Camera-trap photos at suspected roost cavities
• Acoustic recordings of “double knock” sounds and the distinctive nasal “kent” calls associated with the species

The paper was — depending on which ornithologist you ask — either the strongest evidence in eighty years or another iteration of the same fundamentally inconclusive pattern that has dogged this species for generations. The peer-review reception was, predictably, divided. The IUCN currently lists the species as Critically Endangered (Possibly Extinct).

Why the species is so hard to confirm

The honest answer: even if the species exists, finding it definitively is genuinely difficult.

1. Habitat. The remaining bottomland hardwood forests of the southeastern U.S. are dense, swampy, hard to navigate on foot, and limited in observer access.
2. Confusion species. The pileated woodpecker (Dryocopus pileatus) is a much more common species, of similar size, similar plumage, and similar voice — though to a careful observer, the differences are clear. Long-distance, brief, glimpsing observations are exactly the conditions where pileated/ivory-billed confusion is most likely.
3. Tiny population, if extant. Even if the species persists, the most generous estimates put the population at fewer than 50 individuals, scattered across an enormous geographic range. The encounter rate is necessarily very low.
4. The boy-who-cried-woodpecker problem. The repeated cycle of contested rediscoveries has set the bar for “definitive” evidence very high. Photographs that would settle most species questions are dismissed as inconclusive for this one.

What’s actually being done

The U.S. Fish and Wildlife Service maintains the species on the ESA Endangered list. Habitat conservation in southern Louisiana, eastern Arkansas, and Florida continues — partly funded by the species’ ambiguous status, in the same way that some endangered-species protections function as broader habitat protections. Several research groups continue camera-array and acoustic-monitoring efforts. The National Aviary group is continuing its multi-year survey work in southern Louisiana.

If the species is genuinely down to a few dozen individuals across the U.S. range, no current conservation action is plausibly going to recover it. The genetic-bottleneck and demographic-stochasticity issues at population sizes that small are essentially intractable. The realistic best case is that a small, stable, undetected population persists for the indefinite future in remnant forest blocks, recognisable only by the occasional ambiguous trace.

What it tells us about extinction in the modern era

The ivory-billed woodpecker is the cleanest example we have of a category that the modern conservation literature has had to invent: “functionally extinct, possibly persistent.” The species cannot, by any reasonable measure, fulfil its ecological role in the bottomland forests of the southeast — the population is too small, too scattered, and too hard to confirm. But the species cannot, by any reasonable evidentiary standard, be declared extinct.

This is going to become a more common conservation status as climate-driven and habitat-driven declines push more species into the bottom-end-of-detectability range. The ivory-billed woodpecker is, in that sense, the prototype for a category that is going to grow.

The Cuban sub-species (Campephilus principalis bairdii) is a separate story with similar contours: presumed lost since the 1980s, occasional unconfirmed reports, no definitive evidence in decades. The Cuban bird’s habitat — pine forest in eastern Cuba — has been damaged but not lost. Whether the species persists there is, again, a question with no current answer.

Why we keep writing about a bird we can’t prove exists

Because the species is a useful case study for how conservation status is — and isn’t — determined. Because the bottomland-forest habitat conservation work it has motivated has measurable benefits for many other species, regardless of whether Campephilus principalis persists. And because the species is, in some sense, the perfect endpoint of the long American conservation argument: the bird that may or may not still exist, in the forest that we may or may not have logged thoroughly enough to lose forever.

If you ranked the species the world should be most worried about by ecological function lost per individual death, vultures would be at or near the top of the list. They are not charismatic. They are not on T-shirts. They are also among the most efficient ecosystem-services providers in the natural world, and they are collapsing on three continents simultaneously. Below: what’s going on, why it matters more than the headlines suggest, and what’s actually being tried.

Why vultures matter — the part most people miss

A vulture eats carrion. That sentence sounds like a complete description of the species’ ecological role. It is not. A breeding pair of vultures, in a population at full density, can consume the equivalent of an adult ungulate carcass within minutes — and in doing so, they remove from the landscape:

• Anthrax spores
• Tuberculosis bacteria
• Brucellosis
• Foot-and-mouth virus particles
• Botulism toxins
• Rabies virus, where applicable to the carcass

Vulture digestive systems run at a pH below 1.0. The acid kills almost everything. Almost no other scavenger — feral dogs, hyenas, jackals, rats, crows — has comparable pathogen-neutralising digestion. When vultures decline and other scavengers fill the niche, those pathogens cycle further into the environment and into human and livestock populations. This is not theoretical. The collapse of the Indian vulture population in the 1990s and 2000s was directly linked, in peer-reviewed work, to a measurable rise in feral dog populations and a measurable rise in human rabies cases.

The economic-services cost of the Indian vulture collapse, in one published estimate, was around US$24 billion across the affected period. The vultures were doing that work for free.

The Indian vulture collapse

The most documented vulture-collapse story is the Indian one, and it remains the cleanest case study in modern conservation of a sub-continental keystone-species die-off.

Three species — the white-rumped vulture (Gyps bengalensis), the Indian vulture (Gyps indicus), and the slender-billed vulture (Gyps tenuirostris) — were the dominant carcass-cleanup species across the Indian subcontinent through the early 1990s. Within roughly fifteen years, all three populations collapsed by 95–99%.

The cause, identified in 2003 by a research team led by Lindsay Oaks: diclofenac. The non-steroidal anti-inflammatory drug had become the standard veterinary painkiller for cattle in India and Pakistan. When a vulture fed on a carcass from an animal recently treated with diclofenac, the drug caused acute renal failure within days. A single contaminated carcass could kill multiple birds. Across an entire continent’s worth of cattle treatment, the species couldn’t sustain it.

India banned veterinary diclofenac in 2006. Pakistan, Nepal, and Bangladesh followed. Population recovery has been measurable but slow — vultures are long-lived, slow-breeding, and replace lost individuals on a generational timescale. The current Indian vulture populations are, in 2026, an order of magnitude below pre-collapse levels but no longer in free-fall.

The African collapse, ongoing

The Indian story is at least heading in the right direction. The African one is not.

Of the eight African vulture species, six are now listed Critically Endangered or Endangered:

• White-backed vulture (Gyps africanus) — Critically Endangered
• Rüppell’s griffon (Gyps rueppelli) — Critically Endangered
• White-headed vulture (Trigonoceps occipitalis) — Critically Endangered
• Hooded vulture (Necrosyrtes monachus) — Critically Endangered
• Lappet-faced vulture (Torgos tracheliotos) — Endangered
• Cape vulture (Gyps coprotheres) — Vulnerable, formerly Endangered

The drivers are different from India:

1. Poison-baited carcasses for predator control — usually targeting lions, leopards, or hyenas — kill dozens of vultures per bait. A single poisoned elephant carcass killed an estimated 537 vultures in northern Botswana in 2019.
2. Targeted poaching for belief-based use (“muthi”) — vulture parts are used in traditional medicine across southern Africa, particularly in South Africa and Mozambique. The volume is small but the population effect is significant for already-thin species.
3. Power line collisions and electrocutions — vultures soar at the wrong altitudes for poorly-designed pylons.
4. Reduced wild ungulate populations — fewer wild prey carcasses, more dependence on livestock carcasses, more dependence on landowner tolerance.

Closer to home: the New World vultures

The story in the Americas is mixed.

The Californian condor (Gymnogyps californianus) is the textbook recovery case — from 22 individuals in 1982 to over 500 in 2025, of which more than half are now wild-flying. The recovery has cost roughly US$5 million per year for forty years. It works. The remaining species-level threat is lead — almost every wild condor in the programme has elevated blood-lead from feeding on hunter-killed carcasses containing fragmented lead ammunition. The lead-ammunition phase-out for hunting in California was, at root, a vulture-conservation policy.

The Andean condor (Vultur gryphus) — the western hemisphere’s other large vulture — is Vulnerable and declining. The drivers in South America mirror the African pattern: poison baits, persecution by livestock owners, and habitat encroachment.

The North American turkey vulture (Cathartes aura) and black vulture (Coragyps atratus) are doing fine — possibly the most stable vulture populations in the world right now.

What’s actually working

Drug bans

The diclofenac ban in South Asia is the single most consequential vulture-conservation intervention ever taken. It wasn’t a charismatic-species campaign; it was a regulatory action by ministries of agriculture. The lesson — that ag-policy decisions can save bird species — has not been internalised the way it should be.

Vulture restaurants

“Vulture restaurants” — supplemental-feeding sites stocked with diclofenac-free carcasses — have been used to support the captive-breeding-and-release programmes for several Indian and African species, and to keep wild populations away from contaminated landscapes. Cape vulture recovery is partly attributable to a network of these sites in southern Africa.

Lead-ammunition phase-outs

Where it has happened — California for condor recovery, parts of Europe for Egyptian and bearded vultures — the population effect has been measurable. The political effort required has been disproportionate.

Wildlife crime enforcement

Concerted pressure on belief-based-use markets has reduced trade in vulture parts in some southern African countries. The trend lines are still bad but the rate of decline has slowed where enforcement is real.

Why we keep writing about vultures

Because vultures are the cleanest test of whether the public understands ecological value at all. The species are not pretty. They eat dead things. Their conservation case rests on documented, quantifiable disease-suppression services that go away when the birds do. If we can’t make the public case for the species that prevent rabies outbreaks and remove anthrax from the landscape, we have a problem with how environmental journalism — and we include ourselves in this — is communicating value.

Also: the bird with a stomach acid that kills anthrax is, by any reasonable accounting, more important than the species we put on coffee mugs. That’s worth saying out loud.

The polar bear is the species the climate movement decided to make its mascot, and that decision has been a mixed blessing. Below: where the population actually stands in 2026, why the IUCN held the line at “Vulnerable” through the 2024 reassessment, and the structural problem nobody on either side of the debate has solved.

The number, with some humility

The polar bear (Ursus maritimus) is split, scientifically, into 19 sub-populations across the circumpolar Arctic. The IUCN’s last formal assessment in 2024 put the global total at around 22,000–31,000 individuals. That spread is not laziness — it’s an honest reflection of how hard polar bears are to count. The species lives across roughly 4 million square kilometres of sea ice and coastal habitat, in some of the worst flying weather on Earth, and the survey methods (mark–recapture, aerial transects, increasingly genetic-sample harvest) all carry significant uncertainty bars.

What we can say with more confidence:

• Of the 19 sub-populations, roughly four are clearly declining, four are clearly stable, two are arguably increasing, and the remaining nine are too data-poor to call.
• The Western Hudson Bay population — the most-studied sub-population, around the town of Churchill — is now down to roughly 600 bears, from over 1,200 in the late 1980s. That’s the population the climate-movement coverage tends to cite.
• The population in the Chukchi Sea has, against expectations, been stable to slightly increasing.
• Across all populations combined, the IUCN’s quantitative model still projects a >30% decline by 2050 under business-as-usual climate scenarios.

Why the IUCN held the line at “Vulnerable”

The 2024 reassessment kept the polar bear at Vulnerable rather than moving it up to Endangered or Critically Endangered. This was, predictably, controversial.

The IUCN’s reasoning, in plain English: the species is undeniably going to lose habitat at a rate that puts it under quantitative threat thresholds, and that’s why it remains listed. But the present-day population is large, several sub-populations are not declining, and the species shows enough behavioural plasticity (more time on land, longer fasting periods, occasional alternative prey) that the predicted timeline of decline still keeps it above the Endangered thresholds for now.

The argument against this is that lagging indicators always look better than leading indicators, and that by the time the IUCN can document the decline at “Endangered” speed, the species will already be functionally lost across half its range. Both arguments are right. They just frame different parts of the same problem.

What’s actually killing them

Sea ice. Almost entirely, but not quite as directly as the public conversation suggests.

The polar bear’s foraging niche depends on sea ice as a hunting platform. Ringed seals — the bears’ primary prey — pup on the ice, breathe at holes through the ice, and are accessible to bears only when there’s a stable platform to ambush from. The retreating Arctic ice edge has two effects:

1. Shorter hunting season. Bears get fewer weeks each year on stable ice. They’re spending longer fasting periods on land. In Western Hudson Bay, the open-water fasting period has lengthened by an estimated three weeks since the 1980s.
2. Reproductive cost. Female bears need to enter denning weight before winter to successfully gestate and lactate cubs. Below a fitness threshold, they don’t den, or den unsuccessfully. Reduced reproductive success — not adult mortality — is the main demographic driver of decline in the most-studied populations.

This second point matters. The population isn’t crashing because adult bears are starving in dramatic numbers — although that does happen, and the photographs have driven the public conversation. It’s crashing because not enough cubs are surviving their first eighteen months. That’s a quieter, slower, more inexorable process, and it is much harder to reverse.

The other threats, briefly

• Subsistence and sport hunting. Indigenous communities across the Arctic have legally regulated harvest quotas. The numbers (a few hundred bears across the entire range) are biologically sustainable; sport hunting under the same regulatory framework is more politically contested but small in volume.
• Pollutants. Mercury, PCBs, and per- and polyfluoroalkyl substances (PFAS) accumulate in Arctic predators at the top of the food web. Sub-lethal effects on reproduction and immune function are documented. Not the main driver but not negligible.
• Human–bear conflict. Increasing as bears spend more time on land. The town of Churchill, Manitoba — historically the polar-bear capital of the world — has had to scale up its bear-management programme materially since 2010.
• Hybridisation with grizzly bears. Documented in the wild for the last two decades; rare but increasing as grizzly range expands northward. Probably more cultural curiosity than population threat at current rates.

What’s working

The honest answer: very little, at the species level. Local interventions help locally — community ice-watch programmes, conflict-bear translocation, denning-area protection on Wrangel Island and elsewhere — but none of those address the underlying loss of sea ice.

The 2008 U.S. ESA listing was, at the time, a constitutional event for the law: a Threatened listing for a species explicitly threatened by climate change. The agency’s “4(d) rule” carved the listing narrowly to avoid requiring greenhouse-gas-emitting actions to undergo Section 7 consultation. Whether that was the right call is still debated — Esme’s explainer on the ESA covers the legal history. The practical effect: the listing has not changed U.S. emissions trajectory, and was probably never going to.

What you can actually do

This is the hardest “what can you do” section we’ve written for any species, because the honest answer is that no individual conservation action — no donation, no behaviour change, no field-volunteering — affects the polar bear’s outcome at the species level. The species’ future is climate policy at the global scale. Anything else is at the margins.

That said, the actions that matter at the margins:

• Support the small set of organisations doing actual on-the-ice research. Polar Bears International, the Norwegian Polar Institute, and Environment and Climate Change Canada’s research arm are the ones with peer-reviewed track records.
• Don’t go on a “see the polar bears before they’re gone” trip. The well-run tundra-buggy operators in Churchill are net-positive for local conservation funding; the airdropped helicopter excursions further north are a different story. If you’re going, choose carefully.
• Vote on climate policy. We don’t usually do “vote” sentences in this magazine, but the polar bear is the cleanest case for it of any species we cover.

The longer view

If current emission trajectories hold, the species will likely persist as a Northern Greenland and high-Arctic Canadian Archipelago specialist through the second half of this century, with most of the southern sub-populations functionally lost. That is an outcome that takes the species from a circumpolar predator to a remnant in two generations. The biological capacity to survive in those high-latitude refugia is real; whether 5,000 bears in two or three sub-populations counts as the same species, ecologically, as 25,000 bears in 19 sub-populations is the kind of question conservation biologists genuinely disagree on.

The mascot framing has cost the species something, in our opinion. By making the polar bear the iconic “climate change is bad” species, the conversation has tended to flatten the more interesting question — which is what happens to a top predator when its hunting platform is removed faster than evolution can respond. That is a question with implications well beyond the Arctic, and well beyond Ursus maritimus.

The Saola is one of the rarest large mammals on Earth and one of the most enigmatic. It was unknown to Western science until 1992, has never been successfully kept in captivity, and most of the people who study it for a living have never seen one alive. Below: what we actually know, what we don’t, and why a “lost” mammal in the modern era is genuinely possible.

What is a Saola?

The Saola (Pseudoryx nghetinhensis) is a forest-dwelling bovid — related, distantly, to wild cattle and antelope, but in a genus of its own. About the size of a large goat, with a chestnut-brown coat, white face markings, and two long, almost parallel horns that grow from both sexes. The local name in Vietnam translates roughly as “spindle-horned”: sao referring to the spinning posts on traditional weaving looms, which the horns resemble.

The species lives in the wet evergreen forests of the Annamite Range, the mountain spine running along the Vietnam–Laos border. That habitat is rugged, leech-infested, and historically inaccessible — which is part of why the species was missed by Western biologists for so long, and part of why it still might exist.

The 1992 discovery

The species was described in May 1993, based on three sets of horns found in a hunter’s house in the Vu Quang Nature Reserve in Vietnam in 1992. The team — a joint WWF Vietnam / Vietnamese Forest Inventory and Planning Institute survey — recognised immediately that the horns belonged to no described species. DNA analysis later confirmed it was a new genus.

This was a bigger event than it sounds. New mammal species are described every year, but they are almost always small — rodents, bats, shrews. The Saola was a large-bodied mammal, more than two feet tall at the shoulder, and the discovery was the first new genus of large mammal described in more than fifty years. The 1990s were the last era in which “we found a new large mammal” stories made global wire news, and the Saola was the headline of that decade.

What we know

Distressingly little, given that the species has been “known” for thirty-plus years.

• Habitat: wet evergreen forest of the Annamite Range, generally between 400 and 1,500 metres elevation. The species seems to prefer river valleys and ridge-top forest with dense understorey.
• Diet: presumed leaves, fruit, and herbaceous browse. We have almost no direct foraging observations.
• Social organisation: appears to be solitary or in small groups (mothers with calves). Larger group sizes have not been confirmed.
• Captive history: at least 13 Saola have been brought into captivity since 1992. None survived more than a few months. The species seems unable to tolerate the stress of confinement, regardless of veterinary intervention.
• Population: the IUCN’s most recent assessment (2016) lists the species as Critically Endangered. The population estimate is “fewer than 750 individuals, possibly fewer than 100.” Some specialists privately think the real number is closer to single digits, if any.

The last sightings

The last confirmed live Saola sighting was in September 2013, when a camera trap set by WWF and the Vietnamese government in the Quang Nam province captured a single individual. The image — a solid, real photograph of a real animal in the forest — was the first direct visual confirmation of the species in the wild in fifteen years.

There have been credible-but-unconfirmed reports since: hunter accounts, snare-trap evidence, eDNA signals from forest streams. None of it rises to the standard of “we have seen one.” The Saola Working Group (the international consortium of the species’ specialists) has been running concerted camera-trap surveys for more than a decade. At time of writing, no further confirmed sighting has emerged.

This is not unusual for the species. There are decades-long gaps in the historical record. The Saola is genuinely rare, lives in genuinely difficult terrain, and has a body plan and behaviour that minimise its detectability. “We haven’t seen one in twelve years” is, for this species, ambiguous evidence.

What’s killing them

Snares. Almost entirely.

The Annamites suffer from one of the highest densities of wire-loop hunting snares anywhere in the tropics. The snares are not set for Saola — they’re set for muntjac, civet, wild pig, and anything else with hooves. The Saola is collateral damage. The species has a body weight in the same range as the targeted ungulates and steps into the same snare lines.

Snare removal is the operative conservation activity. Forest-guard teams across the Annamites have removed more than 200,000 snares in the last decade. The number set is at least an order of magnitude higher. As long as the Vietnamese and Lao “wild meat” trade and the Chinese demand for traditional medicine ingredients (which uses muntjac and other Annamite species, even if not the Saola itself) remain at their current scale, the snare density will remain at its current scale, and a Critically Endangered species with a probably-double-digit population cannot survive that mortality rate.

The captive-breeding question

The Saola Working Group has, since the late 2010s, been planning a captive-breeding programme. The plan: capture as many Saola as can be located, hold them in a forest-edge facility in Vietnam (the design draws on the limited successful experience with the Annamite striped rabbit and other regional endemics), and breed them with the goal of eventual reintroduction.

The plan has faced two structural problems. First: the species’ captive mortality history. Holding a Saola alive long enough to breed is unprecedented; the working group is investing heavily in stress-reduction husbandry research, and the facility is being designed to minimise human contact, but this is unproven territory. Second: catching one. Camera-trap arrays have not produced the targeted captures hoped for. Without finding individuals to bring in, the programme cannot start.

The 2024–2026 push is the most concerted attempt yet, with eDNA stream surveys identifying candidate watersheds and concentrated camera-trapping inside those areas. If a Saola is captured, the species’ next decade is in a small enclosure in Vietnam. If not, the species’ next decade is — politely — uncertain.

Could it already be extinct?

This is the question we’re asked most. The honest answer:

Probably not, but plausibly so. The species’ detectability is low enough that absence of sightings does not equal absence; the snare pressure is high enough that population decline is essentially certain since the last confirmed sighting; the last twelve years have seen credible-but-not-conclusive evidence of continued presence. The IUCN has not moved the species to Extinct or Possibly Extinct, but the conversation about whether to do so has begun in the last two assessments.

What is virtually certain: the species is functionally extinct in much of its former range. Vu Quang, where the type specimens came from, has not produced a confirmed sighting in nearly two decades. The species, if it persists, persists in a few isolated forest blocks at population sizes that may not be viable for genetic reasons even if individuals exist.

Why we keep writing about a species we can’t see

Because the Saola is, in a way, the cleanest test of whether the global conservation community can still find and protect a large mammal in a known but inaccessible range. The technology, the funding, the institutional partners, the scientific commitment all exist. If we can’t save the Saola, the question of what we can save in the world’s last forested mountain ranges becomes much harder. And because, occasionally, science still throws up species we didn’t know existed — and the Saola is the proof, in our lifetime, that a discovered species can vanish back into the forest faster than it appeared.

If you read only one piece of marine-conservation news this year, it should probably be about reefs. The 2024–2025 global bleaching event was the largest and longest in recorded history, and the structural picture for tropical reefs has shifted in ways that aren’t reversible on any human-relevant timescale. We’ve been sitting with this story for the last six months. Here’s what it actually looks like.

What just happened

NOAA declared a fourth global coral bleaching event in April 2024. By the time it was formally over, in late 2025, the event had:

• Affected coral reefs in more than 80 countries and territories.
• Caused bleaching across an estimated 83% of the world’s reef area at some point during the event.
• Run for roughly 20 months — the longest documented bleaching event on record.
• Pushed sea-surface temperatures across major reef regions to 2–3°C above the historical baseline for sustained periods.

For reference, the previous “worst” bleaching event was 2014–2017. Each of the four global bleaching events on record has been worse than the one before, and the gaps between them have shortened. There is no longer a “between” period that resembles pre-1998 conditions.

Bleaching, in plain English

Coral animals — the tiny polyps that build reefs — live in symbiosis with single-celled algae called zooxanthellae. The algae photosynthesise and provide the coral with sugars; the coral provides the algae with shelter and nutrients. The relationship gives both partners more energy than either could get alone, and it’s the engine that lets reefs grow at the rates needed to outpace ocean erosion.

When water gets too warm — typically 1°C above the local summer maximum, sustained — the relationship breaks down. The coral expels the algae. The white skeleton shows through the now-translucent tissue. That’s bleaching.

Bleaching is not death. A bleached coral can recover if the heat stress eases within a few weeks. What changed in 2024–2025 is that, in many places, the heat stress did not ease. NOAA’s “degree heating weeks” measure — a running total of how much above-normal heat a reef has accumulated — passed thresholds in 2024 that we hadn’t seen before. Reefs that bleached in May were still bleached in November. Mortality, not recovery, became the default outcome.

What’s actually dead

The numbers are still being finalised — reef mortality assessment is slow, expensive, and necessarily lags the bleaching itself. The early estimates from the major monitoring networks:

• Great Barrier Reef — coral cover declines of around 25–35% in the most affected sectors, with the Northern and Central Great Barrier Reef worst hit. The Australian Institute of Marine Science’s late-2025 long-term monitoring report is the bleakest in their 40-year record.
• Caribbean — historically high mortality across Mesoamerican Reef sectors. Preliminary data from Belize and Mexico shows live coral cover dropping below 10% across surveyed sites — a benchmark we’d hoped to never see.
• Indian Ocean — Maldives and Chagos archipelago monitoring shows extensive structural damage; the resilient deeper-water reefs that survived 1998 are now also affected.
• Eastern Tropical Pacific — already-stressed reefs from the 2014–2017 event lost most remaining live coral.

The qualitative picture is bleaker than the percentages suggest. Many of the corals that bleached and survived are smaller, slower-growing, more disease-susceptible species — the structural reef-builders (large Acropora, branching corals that create three-dimensional habitat for fish) have been the worst hit, and they don’t come back quickly.

What lives, and what dies, on a damaged reef

The follow-on for fish and invertebrates is the part of the story that doesn’t make it into the bleaching headlines. A reef with 80% live coral cover supports a different community than the same reef with 30%, even if the fish themselves haven’t bleached. Specifically:

• Obligate corallivores — butterflyfish, the chevron tang, certain wrasses — collapse first.
• Reef-associated grouper and snapper populations contract as the structural complexity that gives juveniles refuge from predators is lost.
• Algae-grazing parrotfish and surgeonfish become structurally critical — they’re the only thing keeping a degraded reef from flipping into an algae-dominated state from which recovery is much harder.
• Sea turtles that depend on reef sponges (hawksbill) and seagrass-edge ecosystems (green) shift their foraging ranges; whether the new ranges are sufficient is an open question.

The shorthand we use on this beat: bleaching is the headline, but ecosystem reorganisation is the story.

What’s actually being tried

Selective breeding and assisted gene flow

Multiple programmes — SECORE, the Australian Institute of Marine Science’s “RRAP”, Mote Marine Laboratory in Florida — are breeding heat-tolerant coral genotypes and outplanting them. The science is real, the results at scale are still being demonstrated, and the cost per square metre is high. None of this is a substitute for slowing the heat stress.

Marine cloud brightening

Australian researchers have field-tested techniques to cool small areas of the Great Barrier Reef during peak heat events. Promising in pilot, expensive at scale, and an emergency-room intervention rather than a cure.

Local stress reduction

Sediment runoff control, water-quality management, fishing-pressure controls, and crown-of-thorns starfish removal don’t stop bleaching but they meaningfully change a reef’s recovery odds. They are also, by far, the most cost-effective interventions available. Boring, unglamorous, and doing more for living coral than any of the high-tech fixes.

Climate

The honest answer for any reef story now is that nothing else matters as much as the global temperature trajectory. The reefs that exist in 2070 will be the ones that happened to have the right combination of depth, current, genetic diversity, and local stress reduction. Every other intervention either buys time or does nothing.

What you can actually do

• If you dive or snorkel: don’t touch, don’t anchor on coral, use reef-safe sunscreen (oxybenzone-free), pick operators that brief properly. None of this saves a reef from bleaching, but it stops you from making the recovery harder.
• If you eat seafood: the Marine Stewardship Council and Seafood Watch databases are the simplest way to avoid contributing to overfishing of reef-associated species.
• Donate to the small set of organisations doing on-the-water reef monitoring and restoration. Coral Reef Alliance, the Reef Resilience Network, and AIMS’s research programmes are where the work is.
• The hard one: vote and act on climate at every level. Reef futures are, fundamentally, a climate-policy question now.

The longer view

Reefs have come through warming events before — the Pleistocene record contains repeated bleaching-and-recovery cycles over tens of thousands of years. The biological capacity to recover is real. What’s different now is the rate. We are pushing reef ecosystems through a thermal regime change in a few decades that, in the geological record, played out over millennia. Species that have the genetic variation to track that change will. Many won’t.

The 2026–2030 window will, on current trajectories, see another global bleaching event. The structural question for the next decade is not whether reefs will continue to bleach but which reefs will continue to function as reefs.

The mountain gorilla is the rarest of the great apes, the most political, and — almost uniquely in modern conservation — the one with a population trend pointing the right way. Below: where the species actually stands in 2026, why it has recovered when most large mammals haven’t, and the unglamorous reasons it could still go backwards.

The number, and where it sits

The most recent census, published from the Greater Virunga Trans-boundary Collaboration in late 2024, puts the global population of mountain gorillas (Gorilla beringei beringei) at around 1,063 individuals. They live in two completely separated populations:

• The Virunga Massif — a chain of forested volcanoes spanning the borders of Rwanda, Uganda, and the Democratic Republic of the Congo. Around 604 individuals at the latest count.
• Bwindi Impenetrable Forest — a single national park in southwestern Uganda, plus the contiguous Sarambwe Reserve in DRC. Around 459 individuals.

That’s it. The entire species. The whole global range fits inside a region you could drive across in a long day, if there were drivable roads through the forest, which there are not.

For context: in 1981, Dian Fossey’s surveys put the Virunga population at around 254 animals. In the late 1980s, after a brutal poaching wave, it dropped further — credible counts went under 250. The fact that the same population is now over 600, after thirty years of work, is one of the more remarkable conservation outcomes of the modern era.

Why mountain gorillas are recovering when others aren’t

You can summarise it in three words: tourism, enforcement, partnership. None of those are surprising. The combination, sustained for thirty-plus years, is what’s surprising.

Tourism with a price tag

Rwanda charges $1,500 for a single one-hour gorilla trek permit; Uganda is around $800; DRC’s Virunga National Park is cheaper but has had repeated security closures. That high price is the single most-criticised feature of the programme — the optics of charging a Western tourist’s monthly mortgage for an hour with a gorilla family are obvious. The economics defend it: the permit revenue funds anti-poaching patrols, ranger salaries, veterinary intervention, and the local-community revenue-sharing that makes the trade-off legible to people who live near the forest. Take the high-priced permits away and the equation collapses inside a year.

Enforcement that actually works

The ranger force across Volcanoes National Park (Rwanda), Bwindi (Uganda), Mgahinga (Uganda), and Virunga (DRC) is large, well-trained, and — for the most part — well-paid by regional standards. Ranger fatalities in DRC have been tragically high; Virunga has lost more than 200 rangers since the park’s founding. The enforcement isn’t theatre. It’s a serious operation that has been the operative variable in the species’ recovery.

Cross-border collaboration

The Greater Virunga Trans-boundary Collaboration — Rwanda, Uganda, DRC — is a genuinely working three-government partnership, which is rare in any field. Joint patrols, shared veterinary protocols, coordinated census methodology. Most large-mammal recovery programmes have nothing equivalent. (Compare: the Amur leopard, split across Russia and China; the Saola, split across Vietnam and Laos. Neither has anything like this.)

What’s still going wrong

The forest itself

Mountain gorillas are squeezed into roughly 800 square kilometres of forest, total. There is no expansion possible — every park is bordered by intensively-cultivated farmland, and Rwanda is one of the most densely-populated countries on the African continent. The species is doing well in absolute terms but it is doing well in a finite container, and an outbreak of disease or a single severe-fire year could erase a decade of recovery.

Disease

Gorillas are close enough to humans, genetically, that they catch our colds. They also catch our scabies, our tuberculosis, our COVID-19. The 2020-2021 period produced documented SARS-CoV-2 cases in gorillas at multiple parks; the ranger and tracker corps was prioritised for vaccination at considerable speed, and the protocols around tourist proximity were tightened (mandatory N95 masks within 10 metres, distance increased from 7m to 10m). It worked. But the threat is structural, not episodic.

Conflict in eastern DRC

The Virunga side of the population sits inside one of the most geopolitically unstable regions in Africa. The 2023-2024 escalation around the M23 rebellion produced repeated park closures, displaced rangers, and re-introduced organised armed groups into corridors that had been clear for years. The Congolese sector of the Virunga population is the most operationally vulnerable subpopulation in the species and it is not a coincidence that the Rwandan and Ugandan sectors have grown faster.

Climate

The bamboo and herbaceous vegetation mountain gorillas eat is climate-sensitive. Bwindi has shown shifts in food-plant phenology over the last two decades. The species is at altitudes (2,200–4,300 m) where there is, simply, no higher to go. They are at the top of their mountain, biologically.

What about the other gorillas?

This is worth saying clearly because the public conversation tends to flatten it. There are two species of gorilla and four sub-species. The mountain gorilla is one sub-species of one species. The others are:

• Western lowland gorilla (Gorilla gorilla gorilla) — the species you’ll see in most zoos. Several hundred thousand wild individuals. Critically Endangered.
• Cross River gorilla (Gorilla gorilla diehli) — under 300 individuals, on the Nigeria/Cameroon border. The most endangered of all gorillas.
• Eastern lowland (Grauer’s) gorilla (Gorilla beringei graueri) — eastern DRC, around 6,800 individuals, declined sharply since the late 1990s. Critically Endangered.
• Mountain gorilla (Gorilla beringei beringei) — the species this piece is about. Endangered (downgraded from Critically Endangered in 2018).

So when somebody says “gorillas are recovering,” that is true of the mountain gorilla and only the mountain gorilla. The other three sub-species are doing worse, and the Cross River gorilla is closer to losing its species than gaining ground.

Going to see them

If you can afford the permit, you should go. The trek is one of the genuine wildlife experiences left on the planet, and the permit money is doing real work. A few practical notes from the team:

• Rwanda’s Volcanoes National Park is the most logistically straightforward starting point. Bwindi is cheaper and the forest is denser; the trek is harder but the experience is, by some accounts, better.
• Take the recommended cold-medicine prep seriously. If you have a respiratory infection on the day of your trek, do the responsible thing and reschedule. The gorillas can’t.
• The 60-minute encounter rule is enforced and exists for the gorillas’ sake, not the tourists’. Don’t push it.
• Tip the rangers and trackers. They are the operative variable.

The U.S. Endangered Species Act is fifty-three years old, more than 1,700 species long, and routinely misunderstood — by its critics and by its supporters. This is a working explainer for how the law actually functions, what it can and can’t do, and the places it is quietly failing right now. None of this is legal advice, but it is what we go back to when we sit down to write any conservation story.

What the ESA is

The Endangered Species Act of 1973 is a U.S. federal law administered jointly by the U.S. Fish and Wildlife Service (USFWS, for terrestrial and freshwater species) and the National Marine Fisheries Service (NMFS, for most marine species). It was passed under President Nixon, with a near-unanimous Senate vote — politically inconceivable today.

The law has four core mechanisms:

1. Listing. A species is added to the Endangered or Threatened list, based on whether it is “in danger of extinction throughout all or a significant portion of its range” (Endangered) or “likely to become endangered within the foreseeable future” (Threatened).
2. Critical habitat designation. Specific geographic areas essential to the species are formally identified.
3. Section 7 consultation. Federal agencies must consult with USFWS or NMFS before authorising, funding, or carrying out any action that may affect a listed species or its critical habitat. This is the workhorse provision — far more impactful in practice than most people realise.
4. Section 9 prohibitions. “Take” of a listed species — defined as harm, harass, hunt, capture, kill, or attempt any of those — is prohibited, with civil and criminal penalties.

How a species actually gets listed

The process is much slower than the public narrative suggests. A typical timeline:

• A petition is filed (anyone can file). The agency has 90 days to make an initial finding.
• If the initial finding is “may be warranted”, a 12-month status review begins.
• If the 12-month finding is “warranted”, a proposed rule is published, with a public comment period.
• A final listing rule is published, typically 12+ months after the proposed rule.
• Critical habitat designation often follows separately and can take years more.

So a clean petition takes 2 to 3 years, minimum. In practice, USFWS and NMFS run a chronic backlog — the agencies’ statutory deadlines are routinely missed, and the law’s “warranted but precluded” finding (i.e., the species qualifies for listing, but other higher-priority candidates are ahead of it) has been used as a holding pattern for some species for more than a decade.

What “Endangered” vs “Threatened” actually means in practice

The two categories produce mostly the same protections, except that “Threatened” species can be subject to “4(d) rules” — special rules tailored to that species, which can either tighten or loosen the default Section 9 take prohibitions. The 4(d) rule for the polar bear, for example, took a relatively narrow form so as not to require all greenhouse-gas-emitting actions to undergo Section 7 consultation.

An Endangered listing has fewer wiggle-room provisions. It is the more protective designation.

Section 7: where the law actually has teeth

If you’ve seen a project — a highway widening, a federal land-management plan, an oil-and-gas lease, a pesticide approval — slow down or change scope because of an endangered species, what was happening was almost certainly Section 7 consultation. Federal agencies have to ask USFWS or NMFS whether their proposed action will jeopardise a listed species or “adversely modify” critical habitat. If the answer is yes, the agency must adopt “reasonable and prudent alternatives” or not proceed.

This is the single most important provision in the law and the one most likely to be weakened by future administrations. We’ve covered the run of federal anti-poaching enforcement elsewhere; the Section 7 mechanism is what gives those enforcement actions their teeth in the first place.

Where the ESA is failing right now

Backlogs

USFWS has acknowledged a multi-year backlog of species awaiting listing decisions. The North American freshwater mussel fauna is the most acute example — there are credible estimates that dozens of mussel species need listing and won’t get it inside the next decade.

Funding

The Recovery Plan for a typical listed species would cost a few million dollars per year to actually execute. The actual ESA recovery budget is a fraction of that, spread across all 1,700+ species. The under-funding produces predictable downstream effects: species sit at low population sizes for decades because the agency can’t afford the habitat work that would let them recover.

Climate-driven listings

The polar bear was the test case. The agency’s reluctance to use the law’s Section 7 consultation requirement against greenhouse-gas-emitting actions has been a quiet, consequential decision. As more species become climate-driven candidates — many marine, many cold-adapted terrestrial — the question of how to do an ESA listing for a climate threat will define the next decade of the law.

Recovery vs. survival

The ESA is genuinely good at preventing extinction. It is much less good at producing recovery. Of the species listed under the ESA, a relatively small fraction — well under 5% — have been delisted due to recovery. The much more common outcome is “stable but listed”, indefinitely.

Where the ESA is genuinely working

The law’s most cited recovery successes are real:

• Bald eagle — delisted 2007.
• American alligator — delisted 1987.
• Peregrine falcon — delisted 1999.
• Whooping crane — still listed but population up from 16 to over 700.
• Brown pelican — delisted 2009.
• Channel Island foxes — delisted 2016, the fastest mammal recovery on record.

The pattern: the species the ESA recovers fastest are the ones with a single, identifiable threat (often a chemical contaminant or a single non-native predator) that can be addressed at the regulatory level. Species threatened by multi-decade habitat loss are much harder.

What it can’t do

The ESA is a U.S. federal law. It does almost nothing for species outside U.S. jurisdiction unless those species are imported into the U.S. or carried by a U.S. flagship vessel. Its reach into private land is limited by the structure of the law and by case law that has clarified the limits of “take” liability over decades. It is also, despite the headline “Endangered Species Act” framing, most useful for species that occupy federal land or interact with federal permits — meaning the species in your local back-yard creek may have technical protection but very little operational protection.

What we cover and what we don’t

On this site we follow the listings as they come out, the Section 7 consultations that produce visible outcomes, and the de-listings — both the recovery wins and the controversial ones. We don’t cover state-level endangered-species lists comprehensively; there are too many and they vary too much.

For the federal picture, see our endangered species archive, and for current annual status see Liam’s earlier annual rundowns. Our broader American wildlife coverage is where most of the U.S.-specific listing stories sit.

For canonical sources, the U.S. Fish and Wildlife Service ESA program page publishes everything in real time, and the IUCN Red List is the international counterpart. They are the two pages every wildlife journalist should have bookmarked.

If we’ve got something here wrong — particularly if you’re a working ESA biologist or attorney — please tell us. The law moves; this page will be updated when it does.

The Amazon river dolphin — the boto, the pink dolphin, the bufeo — is the strangest cetacean most people have heard of and the most under-covered cetacean most people will never see. Below: what’s actually pink about them, why they’re pink at all, where the species sits on the threat scale, and the cluster of myths the species has accumulated.

Are pink dolphins really pink?

Yes — but not all of them, and not all the time.

The Amazon river dolphin (Inia geoffrensis) varies in colour from grey through silver-pink to a startling, unmistakable bubblegum pink. The pink intensifies with three things: age, sex (males tend to get pinker), and physical activity. After a fast swim, after a fight, after mating, an adult male boto can flush a deep pink across his flanks and back — the same way a person flushes when they exert themselves, and for the same reason. The colour is in the capillaries near the surface of the skin. Excitement, exercise and warmth bring blood close to the surface; the pink intensifies. Calm, cold, or relaxed animals are paler.

The other piece of the story: most botos have scarring. Adult males in particular accumulate a network of pale scars from in-fighting and from rough riverbed encounters, and the scarred regions can show pink because the pigment beneath has been disrupted. So a strongly-pink adult male is, in part, a record of his social and physical history.

The basic facts

• Length: Up to 2.5 metres for adult males; females noticeably smaller.
• Weight: Up to about 185 kg.
• Range: The Amazon and Orinoco river basins — Brazil, Peru, Colombia, Venezuela, Bolivia, Ecuador. There is also a separate, smaller, related species — the Bolivian river dolphin (Inia boliviensis) — which some authorities split out and others lump.
• IUCN status: Endangered (assessed 2018, last reviewed 2023).
• Diet: Catfish, piranha, freshwater turtles, crustaceans. The boto’s neck vertebrae are unfused, which lets it twist and turn after prey in a way ocean dolphins can’t.

What makes them weird

A short list of the things that make the boto unlike any cetacean you’d meet in saltwater:

The neck

The vertebrae in a boto’s neck are not fused. It can turn its head 90 degrees side-to-side. Marine dolphins can’t do this. The boto evolved this for a riverine life — for slithering between flooded tree roots, working through tangles of submerged forest, and snapping at fish in the kind of sediment-choked water where echolocation matters more than vision.

The forehead

The melon — the rounded forehead that all toothed cetaceans use to focus their echolocation — is unusually mobile in Inia. Botos can flex it like a putty ball, which gives them more directional control over their biosonar. Useful when you’re hunting through underwater vegetation.

The teeth

Botos have two kinds of teeth — pointed at the front (for grabbing prey) and molar-like at the back (for crushing). Almost no other cetacean has a differentiated dentition like this. It is probably an adaptation to a varied riverine diet that includes hard-shelled prey like turtles.

The eyes

Small. The Amazon is opaque with sediment for most of the year — vision is a low-priority sense. Echolocation runs the show.

Why they’re endangered

The IUCN’s 2018 reassessment moved the Amazon river dolphin from Data Deficient to Endangered. The drivers are unfortunately familiar:

• Bycatch in commercial fisheries. Particularly gillnets set for catfish.
• Direct killing for fish bait. Botos are sometimes killed deliberately and used as bait for piracatinga, a scavenger catfish exported to Colombia and elsewhere. This practice was banned in Brazil in 2014, but enforcement is patchy.
• Habitat fragmentation. Hydroelectric dams in the Madeira, Tocantins, and other tributaries cut populations off from each other. River dolphin populations are not as mobile as ocean dolphins; once cut off, they stay cut off.
• Mercury contamination from artisanal gold mining. Top-of-food-chain animals concentrate methylmercury. Some Amazon populations now show mercury loads at the top of the documented range for cetaceans.
• Climate-driven hydrological extremes. The 2023–2024 Amazon drought reached temperatures in some lakes and oxbows above 39°C. Hundreds of botos and tucuxi died in those events. Scientists at Mamirauá documented the largest single-species die-off ever recorded for the species.

The mythology — and why it might be worth keeping

Almost every Amazonian culture has a version of the same story: the boto is a shape-shifter who, on full-moon nights, becomes a tall, charming young man in a white suit and a wide hat, walks into riverside villages, and seduces young women. Children with no obvious father are sometimes said to be a boto’s. The hat hides the dolphin’s blowhole, which would otherwise give him away.

It’s an extraordinary, recurring myth, and conservationists have started to take it seriously — not as biology but as cultural protection. Communities that hold the boto sacred are demonstrably less likely to kill them deliberately. There’s a real argument that respecting and amplifying indigenous boto mythology is one of the more effective protection strategies actually available, and we tend to agree.

Where you can see one

Several lodges in the central Amazon — particularly in the Mamirauá Sustainable Development Reserve — run respectful, regulated boto encounters. The well-run ones don’t feed the dolphins, don’t allow contact, and keep the swimming activities at arm’s length. The badly-run ones do all three, and we don’t recommend them. If you’re going, check whether the operator is supervised by the Mamirauá Institute or an equivalent science partner.

The Vaquita is the world’s smallest porpoise and, almost certainly, the world’s most endangered marine mammal. The latest acoustic survey put fewer than ten individuals in the upper Gulf of California. We’ve been covering this species for more than a decade. Here’s where things actually stand in 2026, what’s been tried, and what — uncomfortably — looks unlikely to work.

What a Vaquita actually is

If you haven’t seen one — and you almost certainly haven’t — the Vaquita (Phocoena sinus) is a small, shy porpoise. Adults are about 1.5 metres long and weigh roughly 50 kilograms. They have a stubby, blunt body, dark eye-patches, and a charcoal back that fades to grey on the flanks. They live nowhere except the northernmost reach of the Gulf of California, in shallow, turbid water along the coast of Mexico’s Sonora and Baja California states.

The species was first described in 1958, off bones found on a beach. We have, as a global research community, never had a single Vaquita in captivity for more than a few hours. Capture trials in 2017 ended with a captured female dying of capture stress, and the in-situ programme was shelved.

The number: under ten

The 2024 Vaquita acoustic survey — the gold-standard count, conducted from a research vessel by the Comité Internacional para la Recuperación de la Vaquita (CIRVA) — detected sound signatures consistent with between 6 and 10 individuals. Visual confirmation that year identified at least one mother–calf pair, which is the single thing that has kept the conversation open. The genetic load is severe, but recent work on Vaquita genomes suggests the species carries less of the deleterious-allele baggage you’d expect for a population this small. In other words: biologically, recovery is not impossible. The constraints are political.

For context: the IUCN listed the species as Critically Endangered back in 1996. There were an estimated 567 individuals at the time. The collapse from ~600 to under 10 has happened in 30 years.

Why the species is collapsing: gillnets, totoaba, and the supply chain you can’t see

The Vaquita is being killed by bycatch — drowning in gillnets set by small-boat fisheries in the upper Gulf. The fish that drives the gillnet effort isn’t a species most readers will know: the totoaba (Totoaba macdonaldi), an enormous croaker that lives in the same water. Totoaba swim bladders — the dried buche — sell for thousands of US dollars per kilogram in mainland China, where they’re used in traditional medicine and prized as luxury gifts. The totoaba is itself critically endangered, and the trade is illegal under both Mexican law and CITES Appendix I. None of that has stopped the supply chain.

The Vaquita doesn’t eat totoaba. It just lives in the same water, and its body plan is exactly the wrong size for a totoaba gillnet to ignore. This is one of the cleanest cases of cross-species bycatch in the modern record.

What’s been tried

Gillnet bans

Mexico has, on paper, banned gillnets in the Vaquita refuge multiple times since 2015. Enforcement has been the chronic problem: small-boat fishers operate at night, the refuge is large, and the monitoring fleet is a fraction of what would be needed to make the ban real. The Mexican navy now runs patrols inside the “Zero Tolerance Area” — a small box of water where any vessel is presumed illegal. Net retrieval inside that box has improved markedly. Outside it, less so.

Capture-and-translocate

The 2017 VaquitaCPR programme attempted to capture surviving individuals into a sea-pen sanctuary. After the loss of a captured female, the programme’s veterinary team called it. We’ve covered similar small-cetacean conservation challenges in the Amazon; the underlying problem — small, shy odontocetes with very high stress responses — is the same.

Alternative fishing gear

WWF, NOAA, and Mexican fisheries agencies have run a multi-year effort to develop fishing gear (suripera nets, modified trawls) that can catch shrimp without catching Vaquita. The technical work is solid. Adoption has been slow because the alternative gear is more expensive, less efficient, and, crucially, can’t catch totoaba — which is the unspoken core of the local fishing economy.

Demand-side interventions in China

Less reported but more important. The Vaquita won’t be saved at sea; it will be saved or lost by what happens in mainland Chinese consumer markets. Demand-reduction campaigns for totoaba buche have started to land — there are signs that prices have softened — but it’s slow and the data is patchy. Sea Shepherd and several Chinese NGOs have been working this beat.

Can it be saved?

The honest answer: probably not, on the current trajectory. The math is unforgiving — at fewer than ten individuals you can lose the species in a single bad fishing season. The hopeful answer: the genome work, the persistence of mother–calf pairs, and the existence of a clear single threat (gillnets in a single place for a single market) means that if enforcement gets real, recovery is biologically plausible. We have seen species come back from comparable lows: the northern elephant seal once dropped to about 20 individuals.

But “if enforcement gets real” is doing a lot of work in that sentence. The Mexican federal government, the U.S. NOAA, the Chinese consumer-protection apparatus, and a network of NGOs would all have to row in the same direction at the same time, and history suggests they don’t.

What you can actually do

• Don’t buy totoaba product, ever, in any form. The trade is illegal under CITES and you have no way to authenticate a “legal” piece.
• If you fish or eat shrimp, support fisheries certified for low-bycatch gear. The relevant certifications are Marine Stewardship Council (MSC) and Seafood Watch.
• Donate to the small set of organisations actually doing on-the-water net retrieval and demand-reduction work. Sea Shepherd, Museo de la Ballena, and the Vaquita-focused work inside WWF Mexico are the ones we follow.
• Read the IUCN status assessment directly. The Vaquita entry on the Red List is updated regularly and is a better source than most news coverage.

Why we keep writing about a species with ten individuals left

Because the Vaquita story is the cleanest test case of whether modern conservation systems — international treaties, satellite enforcement, demand-side interventions, captive breeding — can save a marine mammal. If we can’t save this one, with everyone in the world watching and a single, identifiable threat, the question of what we can save in the marine realm gets a lot harder.

For the longer arc on small cetaceans, see our coverage of marine wildlife and our reporting on the dolphin and porpoise family. For background on how endangered-species protection is supposed to work, Esme’s piece on U.S. enforcement covers the policy side.

The endangered species story rarely moves in straight lines. Some species recover faster than anyone expected. Others slip onto the list quietly and stay there for decades. Below, a clear-eyed look at what’s changed on the IUCN Red List and the U.S. Endangered Species Act in the last twelve months — and why the headlines often miss the more important shifts.

The headline numbers

As of early 2026, the IUCN Red List counts more than 47,000 species threatened with extinction — that’s roughly 28% of the species the IUCN has actually assessed. The total of assessed species is well past 170,000, and the assessed pool grows every year, which means the threatened count grows even when the underlying biology hasn’t changed. We say this up front because the “more species are endangered” headline you’ll see in early 2026 is partly real and partly an artefact of more species being looked at for the first time.

On the U.S. side, the Endangered Species Act now lists about 1,700 species — the bulk of them plants. Both the listing process and the de-listing process are slower than the science, which is something the team and I have been writing about for years. (Esme has more on the policy side in this piece on the federal poaching response.)

What moved up the threat ladder this year

African forest elephant

Listed Critically Endangered since 2021, the African forest elephant remains the most worrying of the elephant lineages. The latest population work — drawn from dung-DNA surveys across the Congo Basin — keeps the central African population under 100,000, with recovery slower than even pessimistic models predicted. Poaching is no longer the leading driver in most range states; ivory demand has dropped, but habitat fragmentation hasn’t. We covered the broader picture in our coverage of the African ivory crisis.

Sumatran orangutan

Still Critically Endangered, with new estimates putting wild numbers at around 13,400. Forest loss in Aceh remains the operative variable; conservation areas are working where they’re enforced and not working where they aren’t. There’s a reason this species sits on every “ten most endangered” list — there genuinely aren’t very many of them.

Eastern hellbender

The U.S. salamander that nobody outside the herp world thinks about. Reclassified upward this year on the basis of stream-quality declines across Appalachia. It’s a quiet story that tells you almost everything about where U.S. ESA enforcement is headed.

Vaquita

The smallest porpoise in the world, with an estimated population of fewer than 10 individuals. Our marine reporter Priya has covered the Vaquita beat for years, including this longer treatment of the species. There are still some very hard conversations happening about whether the species is still recoverable in the wild.

Genuine recovery stories

Conservation only ever gets oxygen when something dies — but the species that came back are the ones we should actually be studying.

Giant panda

The wild population is around 1,860 individuals and rising slowly. The species was downgraded from Endangered to Vulnerable on the IUCN Red List in 2016 and has held that line. This is what twenty years of habitat protection and enforcement actually looks like, and it is uncommonly hopeful.

Mountain gorilla

Around 1,063 individuals across the Virunga Massif and Bwindi — up from a low of about 250 in the late 1980s. The species remains Endangered, but the trend is genuinely positive. Anti-poaching, eco-tourism revenue, and cross-border cooperation between Uganda, Rwanda and the DRC are the unglamorous reasons why.

Bald eagle

Removed from the U.S. ESA in 2007 and now estimated at well over 300,000 individuals across North America. A textbook case of single-issue legislation (the DDT ban) producing a measurable wildlife outcome.

Where the list is going next

Three structural shifts to watch:

• Climate-driven listings. Species like the polar bear and the American pika make the news, but the bigger 2026–2027 wave will be reef-associated fish and intertidal invertebrates. The IUCN’s marine team has been signalling this for two years.
• Insect declines making it into formal status reviews. Western monarch butterflies, multiple bee species, freshwater mussels — the assessments are catching up with the field data.
• Reassessments removing species that were never well-studied to begin with. Several “Data Deficient” listings are likely to be moved either way as eDNA work fills in baseline numbers.

What you can do that actually matters

This is the section we always agonise over, because most of the “ten things you can do for endangered species” lists are useless. A short, honest version:

• Donate to the actual conservation NGO doing the unglamorous on-the-ground work in your region of interest — not the one with the largest marketing budget.
• Support habitat-level land protection in your own country before sending money overseas. Local conservation tends to be the most cost-effective per species saved.
• Read primary sources. The IUCN Red List is free and public; U.S. Fish and Wildlife publishes every status review. You’ll learn more in an afternoon there than in a year of media coverage.
• If you photograph wildlife, submit your records to GBIF or your national equivalent. Citizen-science records genuinely change assessments.

The honest summary

The 2026 list is, broadly, more species threatened than last year. That’s partly because the biology is bad and partly because we’re looking at more taxa. The arc inside the data is more interesting: a small set of well-funded, well-managed species are recovering, a much larger set of poorly-funded species are sliding sideways, and the marine and insect realms are where the next big lurch will come.

If you’re new to the magazine, the easiest place to dig in further is our endangered species archive, which we keep updated; or our coverage of marine wildlife, where the most under-reported stories on this list actually live.

We’ll keep tracking this through 2026. If we get something wrong, please tell us; the corrections inbox is the most important one we run.
