Arizona Natural Infrastructure Composite

2008-05-08T21:17:01-07:00

GIS data set that integrates 10 local, state, and regional datasets which identify open space lands and sensitive biological lands. This data set is a composite or simplification of the source data sets – the boundaries of all individual data layers have been dissolved into one composite data layer. Note: We did not integrate wildlife linkages data from 2 of the studies in this composite layer because we are awaiting to obtain permission from the source agencies.

Ecological Implications of Verde River Flows

2008-04-07T13:27:00-07:00

Presents a literature review and results of a May 2007 workshop where 35 subject experts from 16 agencies and institutions synthesized the state of knowledge for central Arizona’s Verde River. Report describes the river’s ecosystem, including its hydrology, geomorphology, riparian, and aquatic habitats, and fish and wildlife species – and how components would respond to changes in surface- and groundwater flows.

State of the Las Ciénegas NCA, Part III: Condition of Riparian Habitats and Channel Geomorphology

2008-03-06T17:44:00-07:00

Presents information on the condition of riparian habitats and compares these with objectives established in BLM’s Resource Management Plan. Includes 1) an analysis of data collected between 1990 and 2006 on the condition of the NCA’s riparian forests and stream channel geomorphology, 2) an ecological state-and-transition model that describes relationships between habitat types and disturbance forces, and 3) a review of monitoring protocols with options for making monitoring more informative and efficient.

San Pedro River Wet-Dry Maps

2008-02-04T23:07:00-07:00

The San Pedro River wet/dry mapping dataset is a community effort to track the river’s health by monitoring the persistence of surface water during the driest time of each year. It is created by recording the end points of every wet section of the San Pedro River during June each year. Maps depict the wet portion of the San Pedro River. Maps updated April 14, 2008.

Ecoregional Assessment Geodatabase for Western North America

2008-01-08T00:37:00-07:00

GIS data set that aggregates the information from 19 ecoregional assessments across western North America packaged as a personal geodatabase for use with ArcGIS 9.x and Microsoft Access software products. Note: this data set replaces the six-ecoregion geodatabase formerly posted on this site.

Habitat Mapping and Conservation Analysis to Identify Critical Streams for Arizona’s Native Fish

2007-11-11T00:05:00-07:00

Describes the methods used to develop a GIS dataset for 33 native fish species in Arizona, presents results of some analyses using the data, and describes the data’s utility for the conservation of native fish. This is a preprint of an article published in Aquatic Conservation: Marine and Freshwater Ecosystems, Vol. 17: 737-748 (2007).www.interscience.wiley.com

State of the Las Ciénegas NCA, Part II: Gila Topminnow Population Status and Trends

2007-07-30T23:11:00-07:00

This study analyzed 15 years of data on the endangered Gila topminnow (Poeciliopsis occidentalis occidentalis) to determine the population status and trend at Las Cienegas. We also tested alternative monitoring protocol to provide managers with more timely and reliable information on topminnow populations.

Rivers and Water Management in the Southwest

2007-06-20T23:08:00-07:00

Describes challenges for managing water resources in the Southwest, and recommends actions to improve ecologically sustainable water management. Published in May/June 2007 issue of Southwest Hydrology.

Historical Range of Variation for Potential Natural Vegetation Types of the Southwest

2007-06-11T07:25:00-07:00

Descriptions of the Historical Range of Variation or Variability (HRV) characterize the change over time and space in the condition of the Southwest’s major vegetation types and the ecological processes that shape those types. HRVs enable land managers and the public to understand the drivers of change in our region’s major vegetation types.

Southwest Forest Assessment Project Peer Review Process

2006-10-05T01:25:00-07:00

All of the reports and data sets developed for the Southwest Forest Assessment Project were subjected to external peer review to ensure conformance with the Forest Service’s Science Consistency Review Standards. This report includes a complete list of the resource professionals who reviewed the various components of this project.
