Shrubland Alpine & Grassland Ecology (SAGE) Wildlife Research Group

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...

INHABIT: A web-based decision support tool for invasive plant species habitat visualization and assessment across the contiguous United States

Many managers are hampered by the scope of the invasive species problem compared to their available resources. Habitat suitability models of invaders can help fill this resource gap, helping with activities such as watch list compilation and targeted surveillance and eradication efforts.

Developing searchable annotated bibliographies for resource managers

Resource management decisions need to be informed by up-to-date, quality science and data. However there is sometimes an overwhelming number of scientific publications for managers to consider in their decisions. This project provides concise summaries of recent, peer-reviewed science and data products about different resources and topics of management concern, integrated into a searchable tool.

Fostering greater use of habitat models for managing rare and invasive plants on public lands

Habitat models can provide critical information on the current and potential distribution of plant species, as well as help target and support conservation efforts. Despite their potential utility in public land management, model use may be constrained by a variety of factors including staff access to and trust in models. In this project, we seek to bring together model users and model developers...

Southwest Energy Exploration, Development, and Reclamation (SWEDR)

Approximately 35% of the US and approximately 82% of DOI lands are “drylands” found throughout the western US. These lands contain oil, gas, oil shale, shale oil, and tar sand deposits and the exploration for and extraction of these resources has resulted in hundreds of thousands of operating and abandoned wells across the West. These arid and semi-arid lands have unique soil and plant communities...

Predicting the phenology of invasive grasses under a changing climate to inform mapping and management

Cheatgrass, an invasive annual grass, reduces ecosystem productivity, negatively impacts biodiversity, and is increasingly problematic in higher elevation ecosystems with climate change. Cheatgrass phenology (that is, the timing of yearly growth and lifespan) varies greatly with elevation, climate, and weather from year to year, which can make management planning difficult and reduce the ability...

Assessing the Proliferation, Connectivity, and Consequences of Invasive Fine Fuels on the Sagebrush Biome

Invasive annual grasses can replace native vegetation and alter fire behavior, impacting a range of habitats and species. A team of researchers from the U.S. Geological Survey, Colorado State University, the Bureau of Land Management, and the U.S. Fish and Wildlife Service are working to identify factors that influence changes in the distribution and abundance of invasive annual grasses (IAGs)...

Assessing invasive annual grass treatment efficacy across the sagebrush biome

We are using existing datasets that span broad spatial and temporal extents to model the efficacy of invasive annual grass treatments across the sagebrush biome and the influence of environmental factors on their success. The models we develop will be used to generate maps of predicted treatment efficacy across the biome, which will be integrated into the Land Treatment Exploration Tool for land...

Wild horse and livestock influences on vegetation and wildlife in sagebrush ecosystems: Implications for refining and validating Appropriate Management Level (AML)

USGS researchers are conducting a comprehensive study of wild horse and livestock records across the greater sage-grouse range to investigate impacts on vegetation and wildlife (specifically, sage-grouse and songbirds). Researchers will use these results to evaluate Appropriate Management Levels for wild horse and burros, and projections of vegetation productivity under changing conditions.

Economic assessment of addressing annual invasive grasses across the sagebrush biome

This interdisciplinary project combines expert judgment on treatment costs with spatially explicit ecological modeling to estimate the financial resources needed to address the threat of invasive annual grass across the entire sagebrush biome. Results of the assessment will provide economic insights that can inform cost-effective resource allocation to efficiently achieve sagebrush conservation...
