The Boulder City Field Station supports research scientists leading projects in desert ecosystem restoration, genetics of iconic trees of the Mojave Desert, predator-prey studies on protected lands, and more. Select the next tab for a comprehensive summary of studies at this site.
Symbolized by vast expanses of playas, arid grasslands, shrublands, and woodlands, the deserts of North America support a wide diversity of plants and animals, many of which are found nowhere else. Changing land use patterns and the recent explosion of population growth in the southwestern United States threaten biodiversity and ecosystem integrity in this region.
Lead scientists and staff at the Boulder City Field Station conduct research in desert ecosystems on federal lands managed by the Bureau of Land Management, National Park Service, Department of the Army, Department of Energy, U.S. Marine Corps, and the U.S. Forest Service and on habitats and species of concern to U.S. Fish and Wildlife Service. They provide technical assistance to these agencies and also to state and local jurisdictions, such as the Nevada Division of Wildlife, California Department of Fish and Game, and the Clark County (Nevada) and Washington County (Utah) Desert Conservation Plans pertaining to threatened species. They collaborate with biologists, geologists, cartographers, and hydrologists within USGS, the USDA Agricultural Research Service, the University of Nevada, Las Vegas and University of Nevada, Reno, the University of California, Riverside and Berkeley, and Denver University.

Process-based Approaches for Ecological Restoration of Degraded Drylands
Surface disturbances ranging from military training, recreation, energy exploration and development, and wildfires impact a large majority of federal lands in the western US, but the ecological and economic impacts are poorly understood. Explore this webpage to learn how Dr. Lesley DeFalco and her research team are currently evaluating and refining conventional approaches for post-fire restoration...
Native Plant Materials for Ecological Restoration of Degraded Drylands
There is a growing consensus among resource managers to use native plant materials for ecological restoration of degraded drylands. Some plant species may be suitable for re-introduction across broad environmental gradients. Other species may fail under narrower conditions, or their re-introduction may have genetic consequences for local ecotypes, particularly when adapting to future climate...
Conservation of Rare, Sensitive, and At-risk Desert Plant Species
The Mojave Desert is among the hottest and driest of the North American drylands, but in spite of these extreme conditions, and in part because of them, a diverse flora exists. This diversity of rare, endemic, and endangered species is threatened by the complex interaction between fluctuating climate and human-mediated disturbances. USGS studies have identified rare species “hotspots” for planning...
Aridlands Disturbances and Restoration Ecology
Desert landscapes are rapidly changing due to increases in invasive plant species, frequency of wildfires, urban and energy development, recreational use, military training, and climate variation. Dr. Todd Esque, USGS researchers, and collaborators are working together to investigate these changes and provide managers with key information that can be used to manage natural resources more...
Desert Tortoise Ecology, Health, Habitat, and Conservation Biology
The desert tortoise is listed as “threatened” under the Endangered Species Act. USGS WERC scientists, along with project partners have been conducting long-term analyses on how changes in the southwestern deserts of the United States can affect desert tortoise populations. Dr. Todd Esque and his team are investigating how habitat disturbances and restoration projects influence tortoise populations...
Southwestern Desert Ecology of At-risk Species and their Habitats
The southwestern desert region is home to many sensitive species. Species are at-risk due to past, present, and future changes to the landscape. WERC’s Dr. Todd Esque, field researchers, and collaborators are using models, monitoring plans, and decision-support tools to provide land managers with the resources they need to answer questions about how environmental change influences plants, animals...
Ecology and Conservation of Desert Bighorn Sheep
Dr. Kathleen Longshore’s goal is to understand how predator/prey relationships, disease and human-caused disturbance work separately and synergistically to impact bighorn sheep populations under variable ecological stress. Information from this project will provide managers with an understanding of specific and regional impacting factors that contribute to impact variation in population trends.
Ecology and Conservation of Golden Eagles in the Mojave Desert
Dr. Kathleen Longshore, in collaboration with Dr. Todd Esque, provides information to project the possible conflict between losses of habitat for foraging involved in the proposed development of alternative energy installations in the Mojave Desert and help develop advanced conservation efforts for the golden eagle. Information from this project will also inform California’s Desert Renewable...
