Wild horses and burros are iconic wildlife of the western USA as well as a complicated management issue on tribal, state, and federal lands. Due to their history as domesticated animals, these wild equids – also called “free-roaming” or “feral” equids – can reproduce quickly, and have few natural predators, allowing their populations to grow rapidly if not managed. When populations are too large...

Long-term wildlife monitoring is imperative for understanding population changes that can inform managers. However, working with population data collected by different organizations across multiple jurisdictions and over long time periods can be challenging due to varying data management approaches and organizational priorities. Through this project, we aimed to collaborate with eleven state...

Greater sage-grouse ( Centrocercus urophasianus) are at the center of state and national land use policies largely because of their unique life-history traits and their role as an ecological indicator for the health of sagebrush ecosystems. Multiple science centers with the U.S. Geological Survey (USGS) in conjunction with Colorado State University (CSU) have developed the Greater Sage-Grouse...

Researchers at the U.S. Geological Survey (USGS) and Colorado State University (CSU) collaborated with the Bureau of Land Management and state wildlife agencies to develop a hierarchical population monitoring framework for managing greater sage-grouse ( Centrocercus urophasianus) populations and the sagebrush ecosystems they depend on for survival and reproduction. This greater sage-grouse...

Land and wildlife managers require accurate estimates of sensitive species’ trends to help guide conservation decisions that maintain biodiversity and promote healthy ecosystems. Multiple science centers with the U.S. Geological Survey (USGS), in conjunction with Colorado State University (CSU), developed a hierarchical population monitoring framework for managing greater sage-grouse (...

The sagebrush biome is one of the largest ecosystems in North America. Encompassing nearly one-third of the continental U.S., it provides critical resources for millions of Americans and a home for hundreds of plants and animal species in the West. Natural resource management in sagebrush ecosystems can be complex, and science can support management decisions by providing knowledge and tools to...

The Molecular Ecology Laboratory applies innovative genetic and genomic technologies to address a variety of complex questions and issues facing the Nation's natural resources. While we continually update the scale and efficiency of laboratory procedures to meet stakeholder needs, we must also be innovative and flexible in addressing those needs that have no off-the-shelf solution. We help...

Bats are essential contributing members of healthy, functioning ecosystems. They perform numerous ecosystem services like insect pest control and plant pollination, and provide enormous economic benefits through ecotourism, medical research, and novel biotechnologies. North American bats face unprecedented threats including habitat loss and fragmentation, white-nose syndrome, and wind energy...

The USGS Eastern Ecological Science Center (EESC) provides world-class science to inform natural resource decisions on aquatic ecosystems, species populations and management, disease, and invasive species. Our scientific products represent critical contributions that enhance the ecological and economic sustainability of recreational and commercial fishing. In the United States, anglers contribute...

Understanding the short- and long-distance movements of wildlife is critical for a wide variety of ecological research questions and management decisions. Since the mid-1980s, the USGS Alaska Science Center has used information from telemetry devices on wildlife species to determine locations of animals throughout their annual cycles, understand patterns of habitat use, quantify time spent on...

Once numbering in the tens of millions, plains bison ( Bison bison bison) were nearly driven to extinction with only a few hundred individuals remaining by the late 19th century. Plains bison have since recovered to approximately 20,000 animals managed in conservation herds throughout North America, yet substantial challenges to their recovery remain. The Department of the Interior (DOI) stewards...
