Geospatial Data for Object-Based High-Resolution Classification of Conifers within Greater Sage-Grouse Habitat across Nevada and a Portion of Northeastern California
These products were developed to provide scientific and correspondingly spatially explicit information regarding the distribution and abundance of conifers (namely, singleleaf pinyon (Pinus monophylla), Utah juniper (Juniperus osteosperma), and western juniper (Juniperus occidentalis)) in Nevada and portions of northeastern California.
The California Sea Otter Stranding Network is part of the USGS effort to monitor southern sea otters (Enhydra lutris nereis) and provide data to the U.S. Fish and Wildlife Service. Since 1985, stranded otters from throughout their California coastal range have been collected and analyzed to inform resource management on recovery and conservation of the species.
Suisun Marsh is a critical habitat for wintering and breeding waterbirds in California. USGS is working with the California DWR to examine the trends in bird decline and to assess the habitat factors driving long-term survival of waterfowl, rails, and other birds in this important area.
This public folder contains approved data release products produced by the USGS Western Ecologial Research Center. This folder also includes metadata that will be harvested and displayed by the USGS Science Data Catalog ( http://data.usgs.gov/datacatalog) to improve access and discovery.
The ARMI database provides occupancy and abundance estimates at the project level. Data can be accessed in tabular format or plotted directly via an interactive map browser. The trend data is updated annually and is useful for tracking the status of some of our nation’s amphibian populations.
Genetic Landscapes GIS Toolbox: Tools to create genetic divergence and diversity landscapes in ArcGIS
A new analysis approach in landscape genetics and phylogeography is the creation of “genetic landscapes” to visualize genetic structure across geographic space. The Genetic Landscapes GIS Toolbox contains four tools to map genetic landscapes and to summarize multiple genetic landscapes as average and variance surfaces in ArcGIS ® (Environmental Science Research Institute, Redlands, CA, USA)....
Information on benthic macroinvertebrate populations is currently available from numerous agencies in disparate databases. To maximize the value of these data, San Francisco State University and the U. S. Geological Survey have combined data from several of these sources into a single comprehensive database. To request this database, please contact Dr. Susan De La Cruz (...
Pacific Coast fisheries information is currently available only from wildlife agencies in disparate databases. To maximize the value of these data, BOEM and USGS have combined data from several of these sources into a single, comprehensive database. To request this database, please contact Dr. Susan De La Cruz (firstname.lastname@example.org) and Dr. Josh Adams (...
