USFWS Geospatial Services
-
Geospatial data and services are critical elements needed to meet the mission of the U.S. Fish and Wildlife Service (USFWS). Geographic Information Systems (GIS), Global Positioning Systems (GPS), and remote sensing are the primary elements which fall under the geospatial data and services umbrella. This site was created to enable the USFWS to be effective in managing geospatial data resources and technology to successfully deliver geospatial services in support of the Service’s mission.

The Nature Conservancy Conservation Gateway
-
Spatial data and maps are a crucial element in conservation science, and support meaningful contributions to conservation. Analyses require consistent, regional-scale spatial data and associated products. On this page, you can download the data The Nature Conservancy has used in their large-scale analyses.

USGS National Climate Change Viewer
-
Worldwide climate modeling centers participating in the 5th Climate Model Intercomparison Program (CMIP5) are providing climate information for the ongoing Fifth Assessment Report (AR5) of the Intergovernmental Panel on Climate Change (IPCC). The output from the CMIP5 models is typically provided on grids of ~1 to 3 degrees in latitude and longitude (roughly 80 to 230 km at 45° latitude). To derive higher resolution data for regional climate change assessments, NASA applied a statistical technique to downscale maximum and minimum air temperature and precipitation from 33 of the CMIP5 climate models to a very fine, 800-m grid over the continental United States (CONUS). The full NEX-DCP30 dataset covers the historical period (1950-2005) and 21st century (2006-2099) under four Representative Concentration Pathways (RCP) emission scenarios developed for AR5. The USGS National Climate Change Viewer (NCCV) includes the historical and future climate projections from 30 of the downscaled models for two of the RCP emission scenarios, RCP4.5 and RCP8.5.

NOAA National Center for Environmental Information
-
The National Center for Environmental Information is the world’s largest provider of weather and climate data. Land-based, marine, model, radar, weather balloon, satellite, and paleoclimatic are just a few of the types of datasets available. Detailed descriptions of the available products and platforms are available on the website.

USGS Global Change Monitoring Portal
-
The Global Change Monitoring Portal (GCMP) is a project of the DOI Southeast Climate Science Center and aims to support the efforts of multiple federal, state, and other organizations by providing a centralized, comprehensive catalog of observational networks associated with aquatic and terrestrial ecosystems in the southeastern United States. The Southeast GCMP region of interest encompasses all or part of several Landscape Conservation Cooperatives (LCCs) in the southeastern US and Caribbean. Information about existing and historical observational networks and monitoring sites was compiled into a relational database. Programs and sites are classified according to: type of media being monitored (air, land, water), the general type of measurements that are made (biological, chemical, physical), and the general type of parameters that are measured (e.g., fauna) within a particular measurement type (e.g., biological).

Population Performance Criteria to Evaluate Reintroduction and Recovery of Two Endangered Mussel Species, Epioblasma brevidens and Epioblasma capsaeformis
-
Genetic and demographic modeling of two endangered mussel species, Epioblasma brevidens and E. capsaeformis, in the Clinch River, U.S.A., was conducted to determine quantitative criteria to evaluate performance of extant and reintroduced populations. Reintroduction modelling indicated that the initial population size created during a 5 year build-up phase greatly affected final population size at 25 years, being similar to the population size at the end of the build-up phase, especially when population growth rate was low. Excluding age 0 individuals, age 1 juveniles or recruits on average comprised approximately 11% and 15% of a stable population of each species, respectively. Age-class distribution of a stable or growing population was characterized by multiple cohorts, including juvenile recruits, sub-adults, and adults. Because of current barriers to dispersal and the low dispersal capability of some mussel species, reintroductions will play a prominent role in restoring populations in the United States.
