Principal components of climate variation in the Desert Southwest for the time periods 1980-2010, 2040-2070 (RCP8.5) and (RCP4.5) - data release

Five principal components are used to represent the climate variation in an original set of 12 climate variables reflecting precipitation and temperature gradients. The dataset provides coverage for four regions (the Sonoran Desert, Mojave Desert, Colorado Plateau, and Southern Great Basin) and two time periods: current climate (defined as the 1980-2010 normal period) and future climate (...

Climate Distance Mapper - web application

Climate Distance Mapper is a spatial decision-support tool designed to help land managers match seed sources with restoration sites. Plant populations are commonly adapted to local climate gradients and frequently exhibit a home-site advantage. For this reason, climate information may serve as a proxy for local adaptation in restoration designs. Climate Distance Mapper allows users to rank the...

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.

Annual California sea otter stranding data

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.

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)....
