Cheatgrass invasion in a sagebrush shrubland in northern Colorado

Invasive annual grasses are a growing threat to ecosystems in the western United States. They outcompete native species, influence wildlife habitat, and provide flammable fuels that intensify the wildfire regime. Landscape disturbances and management activities may lead to further spread of invasive annual grasses, and so it is important to characterize the proliferation, connectivity, and consequences of invasive grasses. Moreover, these grasses could impact habitats for species of interest such as the sage grouse. The project is a collaboration of researchers including the USGS FORT Science Center, USGS SC CFWRU, USGS PIERC, the Bureau of Land Management, and Colorado State University. the USGS Forest and Rangeland Ecosystem Science Center and State and Federal natural resource managers in the Pacific Northwest. This project can help develop strategies for managing annual invasive grasses, identifying characteristics and areas to target for appropriate management actions given the patterns and consequences of invasion.
