Ecosystem Change and Disturbance

Federal lands of the US contain important reserves of oil, gas and other resources important for Unleashing American Energy (SO 3418). After development of these resources is complete, successfully reclaiming disturbed lands is a necessary step towards restoring wildlife habitat, forage production, and maintaining natural resources for future use. To improve reclamation outcomes on these lands and...

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 SAGE Wildlife Research Group consists of a large team of research scientists with an interest in conservation and management of wildlife and their ecosystems. Broadly, research involves understanding animal-habitat relationships, with an emphasis on conservation ecology and population demography, and a focus on shrubland, alpine, and grassland ecosystems. We are addressing the effects of...

The scientific literature is abundant on drought-related topics in the western United States, including areas of the Colorado River Basin and the sagebrush biome. Scientists, resource managers, and decision makers use this science to assess, predict, and respond to the effects of drought on people and the environment. However, it can be difficult to quickly synthesize large amounts of research. To...

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...

In recent decades, wildfires have increased in size and intensity, and the fire season has lengthened. This and other factors have increased wildfire suppression costs and risks to human health and safety. Economists in the Social and Economic Analysis Branch (SEA) at FORT investigate numerous aspects of wildland fire, its impacts, and how to mitigate the risk wildfire poses to people, resources...

Wildfires cost billions of dollars to suppress annually, yet they still devastate lives, communities, and ecosystems. While wildfire is a natural phenomenon, learning to live with wildfire is a social issue – so we need a social solution.
