The Rio Grande provides drinking water for more than six million people, irrigation water for two million acres of land in the United States and Mexico, and supports riparian ecosystems that are home to endangered species like the ocelot and Rio Grande silvery minnow. Climate variability and anthropogenic activities continue to stress this already limited water resource. This project was developed in response to a request from a group of stakeholders who work in the Basin and represent federal, state and local agencies, private industry, farmers, ranchers, and NGOs. These stakeholders identified the need for a comprehensive data resource that spatially depicts where conservation activities are occurring on the ground....
The Desert LCC encompasses portions of five states as well as portions of at least ten states in Northern Mexico. The area is topographically complex, including three different deserts (Mojave, Sonoran, and Chihuahuan), grasslands and valley bottoms, and isolated mountain ranges known as the “Sky Islands.” Elevations range from near sea level to over 10,000 ft. The richness of the topography supports equally diverse species composition and habitat for native plants, fish and wildlife species, including many endemic species that are extremely susceptible to climate change impacts. The Desert LCC also includes several large river systems, including the Lower Colorado, Gila, Rio Grande, San Pedro, and Verde Rivers....
ScienceBase brings together the best information it can find about USGS researchers and offices to show connections to publications, projects, and data. We are still working to improve this process and information is by no means complete. If you don't see everything you know is associated with you, a colleague, or your office, please be patient while we work to connect the dots. Feel free to contact
