Landscape changes in the southwestern United States: techniques, long-term data sets, and trends [ More info] This study illustrates some approaches for reconstructing landscape change.
Mapping perennial vegetation cover in the Mojave Desert [ More info] Field data and satellite images allow us to make a calibrated model of percent vegetation cover, which we can use to inform scientific investigations and land management efforts.
Mapping, monitoring, and modeling Western Gateway Community landscape dynamics [ More info] Geospatial analysis of factors affecting communities that are adjacent to Federal lands, especially those lands subject to varying public interest and visitation.
Monitoring and analysis of sand dune movement and growth on the Navajo Nation, southwestern United States [ More info] We combine long-term records from aerial photographs, detailed mapping using survey-grade GPS, and ground-based lidar with meteorological monitoring. Sand dune migration rates are currently about 35 meters per year.
National Coal Resource Assessment: Geologic assessment of coal in the Colorado Plateau: Arizona, New Mexico, and Utah [ More info] Coal resources, stratigraphy, geochemistry, coal quality and geology of coal in the Colorado Plateau, Arizona, New Mexico and Utah. Text in PDF format and available on CD-ROM.
Plague [ More info] History, pathology, and prospects for this historic disease that is still prevalent in animals and remains a threat to humans.
Possible effects of groundwater pumping on surface water in the Verde Valley, Arizona [ More info] We applied a groundwater model to simulate effects of groundwater pumping and artificial recharge on surface water in this area. Results show effects of pumping or recharge on streamflow.
Real-time water data for Arizona [ More info] Consistent, real-time water data from streams, lakes, reservoirs, ground-water, and meteorological sites, are available from the USGS National Water Information System as graphs, tables, or files to download.
Recommended methods for range-wide monitoring of prairie dogs in the United States [ More info] One of the greatest challenges for conserving grassland, prairie scrub, and shrub-steppe ecosystems is maintaining prairie dog populations across the landscape. Of the four species of prairie dogs found in the United States, the Utah prairie dog (Cynomys
Regional assessments of the Nation's water quality--Improved understanding of stream nutrient sources through enhanced modeling capabilities [ More info] Studies of the sources, transport, and fate of nutrients in the streams of six major regions of the conterminous United States.
