Grant funds tree biomass crop research

noreply@blogger.com (Unknown) — Thu, 18 Sep 2014 13:30:00 +0000

Grant recipients at Virginia Tech received $1.4 million to investigate the genetic regulatory networks that will allow an important bioenergy crop to be bred so it will grow in less than ideal soils and
climate.

Populus, a genus of fast-growing trees, produces a significant amount of biomass in two years. Woody biomass can be converted to liquid fuels, such as ethanol.

“There has not been a market for it in the southeastern U.S., but there could be,” said Amy Brunner, associate professor of molecular genetics in the College of Natural Resources and Environment and an affiliate of the Fralin Life Science Institute. “It could also be a resource for power, pulp and paper.”

Gov. McAuliffe: No fracking in George Washington National Forest

noreply@blogger.com (Unknown) — Mon, 15 Sep 2014 15:41:00 +0000

Citing assurances from federal officials, Gov. Terry McAuliffe said fracking for natural gas will not be allowed in the George Washington National Forest.

"I won't allow it as long as I'm governor," McAuliffe told the inaugural meeting of a climate change panel he created this summer. "We made it clear to everyone we will not allow fracking in our national forest. I'm not going to allow it."

The Forest Service initially proposed a ban on fracking in the forest, but it was met with opposition by the energy industry. Opponents fear the U.S. Department of Agriculture (USDA) will bow to the industry pressure. The decision rests with the USDA, which oversees the Forest Service.

Environmental and conservation groups have rallied against any fracking in the forest, which lies primarily in Virginia but also includes a sliver of West Virginia. They fear polluting the headwaters of a primary water source for the region and the industrial footprint drilling would bring.

The science on the impact of fracking has not been conclusive.

Emerald Ash Borer found in more Virginia counties

noreply@blogger.com (Unknown) — Thu, 21 Aug 2014 13:18:00 +0000

The Virginia Department of Agriculture and Consumer Services (VDACS) announced the Emerald Ash Borer (EAB) has been detected in four additional Virginia counties. The newly infested counties include Alleghany, Bath, Fauquier and Page.

EAB has now been detected in 21 Virginia counties and seven cities since its initial appearance in Fairfax County in 2003. The entire Commonwealth of Virginia is under a federal EAB quarantine. The federal quarantine prohibits the interstate movement of regulated articles such as ash logs, ash nursery stock and firewood since these articles have the potential to move the Emerald Ash Borer to areas that are not infested.

EAB is a highly destructive, invasive beetle that has killed millions of ash trees in the US and Canada. Ash trees comprise approximately 1.7% of Virginia’s forests by volume, which amounts to roughly 187 million ash trees, all susceptible to EAB. The EAB larva chews into the soft layer of wood beneath the bark, cutting off the flow of water and nutrients. Trees infected with EAB eventually die. EAB in the larval stage are difficult to detect as they feed under the tree bark enabling them to hitch a ride undetected to uninfested areas when people transport firewood or other infested wood products.

Dr. Chris Asaro, forest health specialist with the Virginia Department of Forestry said, “Options for protecting individual ash trees from EAB are available. People with very large, valuable ash trees would be advised to contact a certified arborist who can treat these individual trees with an effective insecticide every two to three years. Treating these valuable trees is far less expensive than removing a very large, dead tree. Unfortunately, there are no practical management options for EAB in a forested setting.”

The U.S. Department of Agriculture website shows a map of quarantined states and areas, and more information on EAB and other invasive pests is available at http://www.hungrypests.com/.

Oak Galls on White Oak Trees in Northern Virginia Counties

noreply@blogger.com (Unknown) — Mon, 11 Aug 2014 15:06:00 +0000

Homeowners in six Northern Virginia counties have expressed concern about defoliated white oak trees. Forestry officials have conducted aerial and ground surveys and determined that, while this occurrence is fairly widespread, it is concentrated in and around the hills of western Fauquier County and adjacent Loudoun County. Portions of Prince William, Culpeper, Orange and Rappahannock counties are also affected.

The culprit appears to be a very tiny insect known as a gall wasp. There are many species of gall wasps, particularly those that affect oak trees. This type of insect injects eggs into plant tissue, which forms a swelling or ‘gall’ around the injection site. Inside a hollow space within the gall, the developing egg hatches into a larva, and ultimately emerges from the gall as an adult wasp, repeating the cycle one or more times each year depending on the species. Each species of gall wasp specializes on a particular host and plant part, and each species produces a unique gall. Thus, there are a wide variety of plant galls that differ in shape, size, color, texture and the part of the plant affected (leaves, twigs, buds, flowers, etc).

While gall wasps are a normal component of every forest ecosystem, they are generally kept under control by other insects and are not typically abundant enough to cause serious damage to trees and shrubs. However, in rare instances they can become so abundant that their galls can cause noticeable damage.

Info Signs on the Conway Robinson State Forest

noreply@blogger.com (Unknown) — Wed, 06 Aug 2014 15:06:00 +0000

Visitors to the Conway Robinson State Forest can add a “high tech” dimension to their outdoor experience. Informational signs on the forest have been updated to include QR codes. These postage stamp-sized graphics, composed of black-and-white square dots, can guide visitors to information about forest management activities, including promoting wildlife, combating invasive plants and deer control. Visitors simply use their smartphone’s QR reader application to scan the codes and access to the content.

This project is designed to grant visitors an inside look at management on both the state forest and the adjacent National Park Service’s (NPS) Manassas National Battlefield Park.

“Although the forest and the battlefield may appear to be untouched outdoor spaces, they’re actually carefully planned and maintained by natural resource professionals,” said Blake Jordan, area forester for the Virginia Department of Forestry (VDOF). “Not only are these wonderful sites for recreation, but they can teach the public about caring for our natural world. The QR codes allow access to more detailed and descriptive information beyond what can be included on the signs.”

For those who want to learn about the trail from home, the Manassas LEAF website also provides an in-depth explanation of each topic, along with information about the LEAF partnership.

The Manassas LEAF (Link to Education About Forests) partnership is a joint effort of the NPS’ Manassas National Battlefield Park, the VDOF’s Conway Robinson State Forest, and the Virginia Cooperative Extension’s Northern District Natural Resources Program.

PineMap

noreply@blogger.com (Unknown) — Thu, 10 Jul 2014 16:42:00 +0000

The Pine Integrated Network: Education, Mitigation and Adaptation Project (PINEMAP) uses research and education to help southern pine landowners manage forests. Through VDOF’s membership in the Forest Productivity Cooperative, one of PINEMAP’s four primary research installations is at Appomattox-Buckingham State Forest.

These tests are designed to evaluate the effects of climate change, soils and management approaches on planted pine carbon sequestration rates. The results could better prepare us to manage pine forests in response to predicted climate change scenarios and help improve our knowledge of how best to apply thinning and fertilizer treatments to mid-rotation stands.

The annual report for PINEMAP contains updates on all aspects of the effort, including the research, outreach and education tools. The project is funded by the largest grant ever awarded to productivity research in southern pine.

VDOF Seedling Unlocks The Largest Genetic Code Ever Sequenced

noreply@blogger.com (Unknown) — Wed, 21 May 2014 14:41:00 +0000

Using a Virginia Department of Forestry tree seedling, a team of scientists from across the nation has decoded the genome of a loblolly pine tree. With 22 Billion base pairs, this is the largest genome ever sequenced (in comparison, the human genome has 3 Billion base pairs).

Led by Dr. David Neale, professor of plant sciences at the University of California, Davis, the scientific team – using the tissue from a single VDOF pine seedling – broke down the tree’s DNA into smaller, more manageable data pieces and analyzed them with a super-computer. The team then re-assembled the pieces, figured out which genes were present, where they are on the genome, and what they do. This new approach, developed at the University of Maryland, enabled researchers to perform such a large and complex genome sequencing.

“It’s a huge genome,” said Dr. Neale. “But the challenge isn’t just collecting all the sequence data. The problem is assembling that sequence into order. The contribution of loblolly pine tree selection 20-1010 from the Virginia Department of Forestry was critically important not only for the genome sequencing, but more so for all those who follow and will now have completely open access to data and germplasm resources. Researchers worldwide should be very grateful to the Virginia Department of Forestry.”

The Loblolly pine, grown in the orchard at VDOF’s New Kent Forestry Center, was selected for sequencing because of its broad distribution, economic value and long history of genetic research.

Jerre Creighton, VDOF’s research program coordinator, said, “Loblolly pine is the most common tree species in Virginia and the most commercially important tree in the United States. It’s the primary source of pulpwood (used to make paper) and sawtimber (lumber). Today, Loblolly pine is being developed as a potential feedstock for the emerging biofuel industry.”

The results of this research will help scientists breed improved varieties of Loblolly pines, some of which will be more resistant to pathogens, such as fusiform rust – the most damaging disease of southern pines.

“The possibilities are endless now that we know the Loblolly pine genome,” said Creighton. “And what an honor for the Virginia Department of Forestry to have been selected to provide the tree that unlocked the vast genetic code of this important species!”

In addition to UC Davis and the University of Maryland, the research team was comprised of scientists from Johns Hopkins University, Indiana University – Bloomington, Texas A&M University, Children’s Hospital Oakland Research Institute, and Washington State University.

Hike Virginia’s State Forests; June 7 is National Trails Day

noreply@blogger.com (Unknown) — Mon, 05 May 2014 16:30:00 +0000

Forestry officials invite citizens out to Virginia’s state forests to celebrate National Trails Day June 7.

Many of Virginia’s 23 state forests offer miles of trails for walking, hiking and bird watching. Trails allow for recreation and are a great way to get the public to increase their physical activity in an outdoor setting. Trail users can explore in solitude and find peace and tranquility. Or, join family or friends for an outdoor social activity.

Passive recreational opportunities, such as walking, hiking and canoeing, are provided free of charge. Horseback riding, mountain biking, hunting, fishing and trapping all require a State Forest Use Permit when persons 16 years and older enjoy these activities on a state forest.

Located in the Richmond area, the Appomattox-Buckingham, Cumberland, Zoar and Prince Edward – Gallion state forests offer more than 60 miles of trails. A complete list of state forests can be found on the Virginia Department of Forestry website at http://dof.virginia.gov.

Ring Named State Forester of Virginia

noreply@blogger.com (Unknown) — Tue, 15 Apr 2014 16:22:00 +0000

Bettina Ring has been appointed State Forester by Gov. Terry McAuliffe. Ring most recently served as Senior Vice President of Family Forests at the American Forest Foundation where she was responsible for overseeing the American Tree Farm System®, the largest and oldest sustainable woodland program in America, supporting more than 80,000 family forest owners collectively managing 27 million acres of certified woodlands.

Ms. Ring has a long history in the conservation and forestry sectors, having spent 14 years at the Virginia Department of Forestry (VDOF), departing the agency in 2001 as Deputy State Forester. In her role, Ms. Ring was responsible for operations, and helped to develop and implement a new mission, vision and strategic plan for the department. In the years following her VDOF service, Ms. Ring held various leadership positions within nonprofit organizations focusing on natural resources management and conservation, including the Colorado Coalition of Land Trusts, The Wilderness Land Trust and the Bay Area Open Space Council. Ring holds a bachelor’s degree in forestry and wildlife from Virginia Tech and a master’s degree in business administration from James Madison University.

Cankerworms Expected to Make Return Visit to Richmond Area

noreply@blogger.com (Unknown) — Mon, 07 Apr 2014 15:26:00 +0000

As spring finally arrives in the Richmond region, fall cankerworms are expected to return this month with a vengeance, according to officials with the Virginia Department of Forestry.

For the past two years, people in the area have complained about the worms hanging from silken strands in their yards and crawling over everything. In areas where infestations are heavy, people can even hear them eating the leaves off their trees (the sound is actually due to the worms’ frass [bug poop] falling from the trees).

“While cankerworms aren’t harmful to people, they can be a great nuisance or cause distress to those who have a particular aversion to insects,” said Dr. Chris Asaro, VDOF’s forest health specialist. “The real problem is the defoliation they can cause. Typically, one year of heavy defoliation will not greatly harm an otherwise healthy tree, but with two or three straight years of heavy defoliation, tree death becomes much more common.”

Homeowners have just a short time to protect vulnerable trees.

Dave Terwilliger, VDOF’s area forester in Hanover County, said, “There’s a relatively non-toxic insecticide called B.t. that homeowners can have sprayed on trees to control cankerworm, but it must be applied soon after the cankerworms’ eggs hatch to be effective. The best time to do that spraying is when the host tree’s leaves begin emerging. If you wait until you see defoliation, it’s too late for B.t. to be effective and the damage is already done.”

Cankerworms become moths, which begin emerging from the ground in the fall. Female moths are wingless and flightless, and they climb to the tops of trees to lay their eggs. This occurs between November and March. In December 2013, VDOF officials wrapped a band of plastic covered with a sticky substance around the base of 70 trees between Richmond and Fredericksburg to monitor the female moths. As the moths attempt to climb to the top of the trees, they become caught in the sticky bands. Counting the number of female moths in the bands serves as an indicator of potential spring defoliation levels.

Dr. Asaro said, “Typically, catching more than 100 female moths per tree during the winter would suggest heavy defoliation in the spring. Most of the trees we banded had several hundred female moths with some approaching 1,000 female moths per tree.”

Large cankerworm outbreaks are often sustained for only a year or two before their population crashes due to natural enemies, such as birds, disease, insect predators and parasites. During the past couple of years, however, cankerworm activity has spanned more than 2 million acres in eastern Virginia.

According to Dr. Asaro, such an expansive infestation over several years has never been reported before in this region.

“On a broad scale, the current outbreak seems to be self-sustaining, and it’s not clear when a complete population crash will finally occur,” he said. “Due to the limited dispersal of the adult moths, outbreaks tend to recur in the same areas over many decades.”

Homeowners who wish to protect the trees on their property from fall cankerworms are urged to take action now. The focus for protection should be high-value landscape trees, particularly oaks, which are a preferred food source for cankerworms. Contact a professional arborist to perform the spraying operation.

Dr. Asaro said, “In ecological terms, cankerworms and other defoliators can have a beneficial effect on the forest by providing a food source for birds and other wildlife. In addition, all that frass falling to the ground restores nutrients to the soil, which trees can recover through their root systems. Most trees will re-foliate quickly and fully recover from defoliation. The general public should not be too concerned about environmental impacts from this pest.”

Acorn Crop Very Light This Year

noreply@blogger.com (Unknown) — Wed, 27 Nov 2013 15:31:00 +0000

Oaks are among the most common hardwood tree species in many parts of Virginia. Because of their importance both as a source of forest regeneration and as a mast crop for wildlife, each year’s acorn crop is the subject of much attention. Many reports from various parts of the Commonwealth indicate that the acorn crop this fall is very light, according to officials at the Virginia Department of Forestry (VDOF) and the Virginia Department of Game and Inland Fisheries (DGIF).

VDOF Research Program Manager Jerre Creighton said, “Acorn production varies widely – from nearly zero to a quarter million or more acorns per acre. Different locations, years, species and even individual trees produce extremely different crops, and heavy ‘bumper’ crops occur only every two to seven years.”

Many factors – such as weather, insects and disease – that collectively influence acorn development from the time of flower initiation to acorn maturity.

Late spring freezes and high humidity during pollination are primary causes (we experienced both of these over much of Virginia in 2013). In addition, research has shown that the inherent cycles between bumper crops and light crops may be an adaptation to allow the trees to restore their resources following a bumper crop.

Creighton said, “In other words, a large crop one year may reduce the trees’ resources resulting in lower production the following year(s). Since 2012 was a bumper crop of acorns for much of Virginia, this could be another explanation for this year’s light crop. The overall consensus seems to be that there are inherent cycles of reproduction that are modified by the impact of weather conditions in a particular location.”

Gary Norman of DGIF said, “Acorn production in Virginia in 2013 was low – comparable to the previous low in 2008. The white oak crop appeared to uniformly fail across the state, while some pockets (generally in eastern Virginia) of good red oak production were found. Mast production has alternated from high to low levels since 2010. The impacts of acorns on wildlife populations are extensive and complex. And they are most dramatic where there is little diversity of habitat types and few alternative food sources to acorns.”

DGIF officials are concerned about a light crop because acorns are a preferred food for many wildlife species, including white-tailed deer, black bear and wild turkey. Acorns are rich in fat, soluble carbohydrates and energy, which are important nutritional needs that contribute to the animal’s body condition, survival, harvest rates, reproduction and, eventually, population status. The roaming range of black bear and wild turkey can increase two- to four-fold in years with mast failures, and long-range gray squirrel movement can be significant as they search for acorns.

Norman said, “Oftentimes the search for food creates situations that bring wildlife closer into residential areas to find human-related food sources resulting in unwanted interactions between animals and people.”

Forests and Fall Migration

noreply@blogger.com (Unknown) — Wed, 13 Nov 2013 13:23:00 +0000

At this time of year, Virginia’s forests are changing in ways beyond the obvious fall color display. Forest dwellers are changing their seasonal habits as well. Birds and waterfowl, noticing the drop in temperature, shorter days and dwindling food supply, are beginning their annual migration.

A streamside forest is a great place to observe birds and waterfowl migrating from September through January. Follow the trails along rivers, streams and forested shorelines. These riparian buffer zones, with habitat and food for a variety of ducks and birds, are great places to watch the activity.

Migratory species require frequent meals to sustain their energy. Favorite foods include insects, small fish, fruits, small nuts and seeds.

Migrating finch are on the lookout for small seeds. River Birch, Sycamore, Sweet Gum, Cottonwood Poplar and pines all have smaller, nutrient-rich seeds to boost the energy level of migratory species. Turkeys scour for acorns. After a frost, fruits such as soft persimmons, holly berries and dogwood berries have high sugar content, making them a good migratory snack. Some fruits remain on trees throughout the winter, providing forage for the year-round residents that don’t migrate, such as cardinals.

Fall Fire Season Now Underway

noreply@blogger.com (Unknown) — Wed, 16 Oct 2013 18:40:00 +0000

As temperatures begin to dip and the leaves on the trees begin to change color, it’s time once again for the start of fall wildfire season in the Commonwealth. Officials at the Virginia Department of Forestry (VDOF) remind all Virginians that the threat of wildfire increases each autumn as leaves dry out and fall from trees, grasses turn brown, humidity levels drop and winds increase.

“Wildfires are directly linked to weather conditions,” said John Miller, director of resource protection at VDOF. “Whether it’s someone burning debris or trash, an unattended campfire or an intentional case of arson, wildfires have a greater chance of causing bodily harm or property damage in the fall and spring months because the conditions are right for fires to burn hotter and spread faster.”

Each year, Virginia experiences more than 1,200 wildfires that burn more than 10,000 acres of land. VDOF employees annually protect hundreds of homes from the ravages of wildfires, but each year there are always some homes that are destroyed by these wildfires.

Miller said, “Since more than 95 percent of wildfires that occur in Virginia are the result of human activity, taking even the simplest precautions with outdoor fires will significantly reduce the occurrence of wildfires and the threat to you and your neighbors.”

Fall Fire Season runs annually from October 15 to November 30.

VDOF Working to Plant Trees on Open Lands

noreply@blogger.com (Unknown) — Fri, 20 Sep 2013 12:16:00 +0000

As part of its Open Lands Tree Planting Initiative, the Virginia Department of Forestry has hired a mapping and outreach specialist to work out of the Mecklenburg County Forestry Office. Tim Minich will analyze land-use data from multiple sources, identify appropriate land for tree planting and conduct some field forestry work in one of three outreach focus areas of the Commonwealth.

The Open Lands Tree Planting Initiative is designed to prevent the loss of forestland; increase the sustainability of the forest resource, and improve water quality and diminished species concerns. The strategies to tackle these issues are to: promote and enhance forested watersheds; improve stewardship, health, diversity of forest products, and conserve the forestland base.

Senior Area Forester Adam Smith said, “The opportunities to consider in the open land outreach are to increase forests and benefits; plant pine in the more than 71,000 acres each year that revert back to a natural forest, and to overcome the natural reversion of forest stands that are under stocked with undesirable species.”

Minich will be working with area VDOF employees who have local knowledge and extensive county contacts, along with partner agencies, such as the Soil and Water Conservation District, the Natural Resources Conservation Service, the Farm Service Agency and Virginia Cooperative Extension. He will send letters to land owners, conduct presentations for community groups and develop landowner workshop opportunities.

Minich said, “The state target goals will be 200 new sites and more than 2,000 acres of open land on which to plant.”

Smith said, “We are confident the additional outreach efforts will pay great dividends. The Virginia Department of Forestry will provide the tools and the manpower to assist any interested landowner with available cost-share funds from state and federal sources. It is a win, win situation for all.”

Minich will focus his efforts in the counties of Mecklenburg, Lunenburg and Brunswick but will also do some work in the counties of Prince George, Sussex, Surry, Isle of Wight, Greensville, Southampton and the City of Suffolk.

To learn more about the Open Lands Tree Planting Initiative or to contact Tim Minich, please call 434.738.6123.

Southwest Virginia Residents Starting to See Widespread Decline of Hemlocks

noreply@blogger.com (Unknown) — Wed, 18 Sep 2013 12:53:00 +0000

Hemlock trees are an important component of the forests in southwest Virginia, but they are under attack by a tiny insect capable of killing the trees, according to officials with the Virginia Department of Forestry.

While not a major timber species, hemlock trees have numerous environmental benefits due to their high tolerance for shade. Hemlocks grow particularly well along stream sides and moist cove habitats, providing deep shade that helps moderate temperatures, enhances habitat for fish and wildlife, and increases overall biodiversity.

Senior Area Forester Bill Miller said, “The tiny, aphid-like insect called the hemlock woolly adelgid (HWA), which is an invasive species from Asia, poses a major threat to the hemlock resource.”

Accidentally introduced to Richmond, Va., in 1951, the insect has since spread throughout the entire native range of hemlock within the Commonwealth. However, despite its presence in Virginia for more than 60 years, it took most of that time to reach the southwestern Virginia counties bordering Kentucky and Tennessee, where it’s been known for only the last five to 10 years. New county records for the hemlock woolly adelgid were established for Russell and Tazewell in 2005; Buchanan, Dickenson, Wise and Lee in 2006, and Scott in 2007.

VDOF Forest Health Specialist Dr. Chris Asaro said, “Hemlock woolly adelgids are immobile after finding a suitable place on the tree to feed. They insert their straw-like mouthparts into the terminal ends of hemlock branches, sucking sap and producing a white, waxy coating over their bodies, which looks something like tiny balls of cotton. Adult female hemlock woolly adelgids also lay their eggs within this protective wax. Most people never observe the actual insects, but are more likely to see these tiny white balls of wax scattered around the underside of twigs and terminal branches.”

While many species of insects suck sap in this way and are mostly harmless, HWA is unique in that its saliva is toxic to eastern hemlocks in North America, according to Dr. Asaro. Thus, their feeding causes localized tissue damage and death, which spreads from twigs to branches and, ultimately, to the entire tree. This process of decline and death from their feeding will often occur within five years of initial attack. However, this is highly variable, and many hemlock trees infested with HWA have survived for many more years without showing symptoms of severe decline. Scientists still don’t fully understand what factors dictate this variability; but older, larger trees seem to succumb more quickly than mid-sized trees and saplings, at least in some locations.

Increasingly, homeowners and landowners across southwest Virginia are becoming more aware that something is wrong with their hemlocks, but may not understand the cause. However, once identification of HWA occurs, there are some control options available. While it’s true that hemlocks will likely continue to decline and die in many forested locations, it is also possible for homeowners to protect their ornamental hemlocks using a variety of products available over-the-counter.

Miller said, “For smaller trees in which all parts of the tree are easily reached, insecticidal soaps or horticultural oils are quite effective, and are relatively safe to use and easy to apply. The down side is that they wash off fairly regularly and have to be reapplied with greater frequency, especially the soaps. Soaps, however, are extremely safe to handle and are relatively non-toxic. Oils are slightly more toxic than soaps but don’t have to be reapplied as frequently. Both are fairly inexpensive.”

For protection of larger trees, systemic insecticides that can be applied to the soil and root zone are available. Systemic insecticides are taken up by the tree through the roots over several months until the product is circulated through the entire tree.

Dr. Asaro said, “This can sometimes take up to six months depending on tree size and other factors, so it should be applied before trees start to decline significantly. Systemic insecticides work best if applied in the springtime. If too much of the crown is already killed, uptake of the insecticide will be poor.”

These products are considered easy to use but are more expensive. However, one application to the soil usually affords two to three years of protection to the tree before it needs to be reapplied.

Dr. Asaro said, “These systemic products should not be used near water or in areas with a high water table, or near trees or crops that are pollinated by insects. Follow all pesticide label directions exactly; the label is the law.”

Homeowners should be aware of their options for protecting their hemlock trees. Unfortunately, HWA is becoming a fact of life for this area and will no doubt impact many landowners negatively. For more information about HWA, please contact your local Virginia Department of Forestry or Virginia Cooperative Extension office.

Scattered yellow-poplar decline reported across Lee, Wise and Scott counties

noreply@blogger.com (Unknown) — Mon, 16 Sep 2013 12:55:00 +0000

Recent declines in yellow-poplar in Lee, Wise and Scott counties have landowners concerned over the health of one of the most abundant and resilient hardwood trees in Virginia’s forests. While not entirely certain about the reason for the declines, Virginia Department of Forestry personnel believe they may stem from past insect infestations that previously went unnoticed.

Yellow-poplar, or tulip poplar, is the most common hardwood tree in Virginia and one of the most important timber species in far southwest Virginia. Its rapid growth, straight trunk and wood properties, along with its abundance, make it an excellent tree for loggers to harvest in bulk and bring to the mills. Generally speaking, yellow-poplar is a resilient tree that does particularly well in moist cove habitats and fertile soils common to the lower slopes and valleys of the southern Appalachians. It also has very few insect and disease problems due to the fact that the leaves, bark and wood contain a host of chemicals that deter them. Even an invasive species like the gypsy moth, which can feed on more than 200 species of trees and shrubs, will completely avoid feeding on yellow-poplar.

“Two notable exceptions to this rule, however, are native insects known as the tulip tree scale and the poplar weevil,” said Bill Miller, senior area forester with the Virginia Department of Forestry. “The scale is a tiny sap-sucking insect that produces a brown, waxy covering that looks something like a tortoise shell. Populations of these insects can occasionally reach such high levels in the forest that they can damage and even kill poplar trees, although this is rarely seen in southwest Virginia.”

On the other hand, the poplar weevil is a defoliating insect that is particularly common in southwest Virginia, especially in Lee, Scott, Wise, Dickenson, Buchanan, Russell and Washington counties, along with adjacent counties in Kentucky and Tennessee. In most of these counties, as many as six to eight poplar weevil outbreaks have been documented over the last 25 years by forest health personnel with the Virginia Department of Forestry. Feeding by individual weevils in spring causes little damage to newly emerged leaves, other than a small brown patch. During outbreaks, however, millions of weevils can result in poplar trees being heavily defoliated. These outbreaks are often patchy in nature but can span large areas.

VDOF Forest Health Specialist Dr. Chris Asaro said, “While the word ‘outbreak’ can sound very dramatic, the truth is that these defoliation events are often not noticed from the ground for several reasons: they are very patchy across the landscape and often occur in remote areas that are not easily visible. In addition, poplar trees are generally quite tall and most people driving by don’t have the tendency to look up. Furthermore, while complete defoliation of poplar can occasionally occur, trees with adequate moisture often leaf out again pretty quickly, erasing any evidence of past damage. Outbreaks typically don’t last very long in any one area either because poplar weevil has a host of other insects that prey on them, which usually causes outbreak populations to crash after a year or two.”

While one defoliation event by itself is probably not going to cause poplars to decline or die, several defoliation events over successive years can weaken trees and, combined with other stressors such as drought, lead to some localized dieback, decline or even death. Recently, some landowners across Lee, Wise and Scott counties have seen such poplar decline over the last few years and have expressed concerns to local foresters. In most cases, these areas of decline are small – generally from ½ acre to several acres in size – although several locations have exhibited decline spanning 50 acres to 100 acres.

“There appears to be no obvious reason why these declines show up where they do, other than the fact that these areas were known to have several weevil outbreaks during past years,” Asaro said.

“Because tree decline is a gradual process that can take many years and be caused by multiple agents, it’s always difficult to pinpoint exact causes. But knowing that the weevil is a major presence in the region and one of the few insects that can feed on poplar, it seems very possible that it is playing a prominent role in these decline events,” Asaro said.

The good news is that the affected areas are quite small, and most of the poplar trees are weakened but not dead. That means the wood is probably still sound and can be salvaged, so most landowners can still profit from forests with some poplar decline. Forest landowners concerned about their poplar stands should consult their local Virginia Department of Forestry office for further information and advice.

New Community Planning Resource Guide Available

noreply@blogger.com (Unknown) — Fri, 13 Sep 2013 13:48:00 +0000

Citizens or communities across Virginia will be better able to map their most significant natural resources and to prepare plans to conserve or restore them thanks to a new guidebook prepared by the Green Infrastructure Center (GIC) in Charlottesville.

“Evaluating and Conserving Green Infrastructure Across the Landscape: A Practitioner’s Guide” is a 132-page spiral-bound guide that presents a way to think about and catalogue a community’s natural assets as well as to prioritize them for long-term stewardship. The guide is based on six years of field testing from the Eastern Shore and coastal plain to the Piedmont and Shenandoah Valley. It sells for $29.95.
Green infrastructure includes all the interconnected natural systems in a landscape. These include intact forests, woodlands, wetlands, parks, rivers, and soils that help provide clean water, clean air, wildlife habitat and food.

“This is not a guide about how to stop development or limit population growth,” said GIC Director Karen Firehock. “It describes the steps a community can take to determine what is important and develop a rationale for what to protect. The guide helps planners, land trusts and community groups determine where their most significant natural assets, such as large intact forest blocks, are located. They can also determine which of these assets are the most important for achieving key functions, such as protecting clean water, supporting wildlife or providing outdoor recreation.

“If we don’t know where our best watershed areas are or where our best quality agricultural soils are located, this vital information isn’t included in the comprehensive plans, master plans or zoning laws that guide development,” Firehock said. “Once such natural resources are removed from the community, they are most often lost forever.”

The guide provides the steps for determining how to facilitate development in ways that reduce its impact on the landscape. It also provides the steps to use cost-free state models to develop maps that can inform planners, builders, community groups or agencies in making the best decisions on how and where to develop and what to conserve.

“While most people would prefer to make land-use decisions that restore rather than deplete our environment, land planners and decision-makers may still overlook natural resources,” Firehock said. “But, just as we plan for our gray infrastructure – roads, bridges, power lines, pipelines, sewer systems and so on – we should also plan to conserve landscapes and natural resources as our green infrastructure.”

To order a copy of the guidebook, send a check for $29.95 made payable to the Green Infrastructure Center, to P.O. Box 317, Charlottesville, VA, 22902 or visit www.gicinc.org/ . The guidebook was funded by the Virginia Department of Forestry, the US Forest Service’s Southern Region and the Blue Moon Fund.

Several Virginia Counties Seeing Increased Levels of Southern Pine Beetle

noreply@blogger.com (Unknown) — Wed, 11 Sep 2013 12:39:00 +0000

Based on the spring trapping survey, the southern pine beetle (SPB), once again, is not expected to reach outbreak levels in most VA locations, but there are several areas that have seen increased populations of the bug, according to officials with the Virginia Department of Forestry.

Populations increased somewhat in Cumberland and Chesterfield counties compared to last year, but overall numbers were still relatively low, according to Dr. Chris Asaro, forest health specialist.

“As always, this does not mean that localized infestations will not occur. In fact, western Hanover County has been plagued with SPB outbreaks for the last three years, and there is a fair probability that it will be declared an outbreak county by year’s end if current trends continue,” Asaro said.

An outbreak is defined as one SPB spot per thousand acres of host type (pine) per unit area, but this is a crude definition because many small spots can join together to form one large spot, which has happened in Hanover already.

“Folks in southern portions of Spotsylvania and Caroline counties as well as eastern portions of Louisa and Goochland counties may want to keep a close eye on their pines for any potential spillover from Hanover.The hope is that there is enough hardwood cover around to prevent any major spillover, but large areas of contiguous pine cover would obviously be a concern,” Asaro said. “Another area experiencing outbreak levels of SPB is Chincoteague/Assateague Island, although there is no widespread activity reported along the rest of the Eastern Shore.”

Virginia has not experienced a statewide outbreak of SPB since 1993, when more than 50 counties were affected and $14 million worth of timber destroyed.

Veteran VDOF Employee Honored for Education Efforts

noreply@blogger.com (Unknown) — Mon, 09 Sep 2013 19:26:00 +0000

A 34-year veteran of the Virginia Department of Forestry (VDOF) has earned the Bronze Smokey Bear Award.

Toano resident Paul Reier, a forestry technician who protects and serves the counties of Charles City, Hanover, Henrico, James City, King & Queen, King William and New Kent, was nominated for the “energy, dedication, and commitment” he demonstrated in countless Smokey Bear education programs.

“Paul works tirelessly, even after hours, to ensure Smokey is at numerous fairs, special events, baseball games and schools. He partners with everyone from local nursing homes to the local rescue organizations and fire departments,” said Fred Turck, VDOF’s assistant director of resource protection. “Paul always finds new ways to get Smokey Bear involved in community events and is proactive in his efforts.”

State Forester of Virginia Carl E. Garrison III said, “I'm so glad to see Paul's extraordinary efforts being recognized on a national level. He has been a leader in wildfire prevention and education efforts for many years, and he's so very good at making sure Smokey Bear's message (“Only You Can Prevent Wildfires”) is understood by children of all ages. His work has been an important part of our goal to reduce the number of wildfires casued by human activity. Paul Reier is most deserving of this Bronze Smokey award, and I congratulate him on his achievement.”

The Bronze Smokey Bear Award is the highest honor given for wildfire service on the state level, and is reserved for people or organizations that provide sustained, outstanding service in wildfire prevention. The award is sponsored by the United States Department of Agriculture (USDA) Forest Service, the National Association of State Foresters and the Advertising Council.

Forest Conservation Easement Protects 306 acres in Sussex County

noreply@blogger.com (Unknown) — Thu, 05 Sep 2013 14:37:00 +0000

In 1961, when Mrs. Segar White Guy inherited her father’s 306-acre tract of unmanaged forestland in Sussex County, she made the long-term commitment to improve the quality of the woodland. The Virginia Department of Forestry (VDOF) and Consulting Forester Hunter Darden developed a Forest Stewardship Management Plan that eventually led the family to prosperity and a healthy forest.

Fifty years and several forest management awards later, the timber on the land was both healthy and profitable for the Guy family. Cash from timber and pulpwood sales supported the family quite well, even covering the cost of their daughter Judi’s college tuition. In late 2010, however, the Guys learned Segar had pancreatic cancer, and, subsequently, the family decided it needed to protect their greatest family heirloom – the forestland.

Like the Guy family, many Virginia forest landowners face the issue of how they will pass their land down to the next generation. Private owners hold 13 million acres of Virginia’s forestland; landowners age 55 or older own seven million acres of that. With the decisions made today, these landowners will either protect our farms and forests or convert to them to other uses. For some families, perpetual protection from development provided by a conservation easement with VDOF is the answer.

Segar’s goal was to keep the land in the family and pass it on to the next generation.

Daughter Judi Guy said, “My mother wanted the land to go into conservation easement because of the feature of perpetuity for the land being used for sustainable forestry management using Best Management Practices. The tax benefits were of secondary concern to her.”

John Guy, Segar’s husband of 56 years, said, “Segar had a deep love of the land. She became actively involved with many forestry organizations that helped her become a good steward to the land.”

After 50 years of working with VDOF, Darden, the Virginia Forest Education Foundation (VFEF) and the Virginia Forestry Association (VFA), Segar’s vision of good forest management came to fruition by becoming certified under Virginia’s Forest Stewardship Program.

After several months of work, the Guys, their attorney Lee Stephens and VDOF Forestland Conservation Specialist Rob Suydam recorded the conservation easement on April 3, 2013 – nearly two years to the date of Segar’s passing.

Judi said, “This was such great news. The irony is it was two years ago we lost Mom. The timing could not have been more meaningful to me.”

Forest Legacy Program Coordinator Wins National Award

noreply@blogger.com (Unknown) — Tue, 03 Sep 2013 13:58:00 +0000

Larry Mikkelson, our Forest Legacy program coordinator here at VDOF, earned the national Conservation Excellence Award 2012. He is only the fifth recipient of this award in the 108-year history of the U.S. Forest Service.

The award recognizes his “exceptional leadership managing a state’s Forest Legacy program.” Scott Stewart, national director of the Forest Legacy program, presented the award.

The USFS Forest Legacy Program (FLP) supports state efforts to protect environmentally sensitive forestlands. Designed to encourage the protection of privately owned forestlands, FLP is an entirely voluntary program. To maximize the public benefits it achieves, the program focuses on the acquisition of partial interests in privately owned forestlands. FLP helps the states develop and carry out their forest conservation plans. It encourages and supports acquisition of conservation easements, legally binding agreements transferring a negotiated set of property rights from one party to another, without removing the property from private ownership. Most FLP conservation easements restrict development, require sustainable forestry practices and protect other ecosystem service values.

Virginia has received 10 Forest Legacy grants since 2001. VDOF holds 11 easements on 5,287 acres of forestland. In addition, the Forest Legacy program helped purchase all or parts of three state forests (Sandy Point SF; Dragon Run SF, and Big Woods SF) and two natural area preserves (Chubb-Sand Hill NAP and South Quay Sand Hills NAP).

A 35-year veteran of the Virginia Department of Forestry, Larry graduated from Purdue University with a degree in forestry.
