Shrubland, Alpine and 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 energy development and land-use change on conserving wildlife populations, their habitats, and the ecosystems they inhabit, and work closely on these issues with state and federal partners, NGOs, conservation groups and industry.
Species we currently study include songbirds, mammals, snakes, lizards, and grouse, such as white-tailed ptarmigan and sage-grouse. We also work with plant communities and exotic invasive plants to understand how external drivers such as grazing and energy development affect plant communities and thus, wildlife. We work across spatial scales and use statistical and empirical modeling to answer research questions, many of which have direct applications for conservation and management of species, most notably sage-grouse, and their habitats.

New tools for a growing threat: Co-developed science informs the fight against invasive grasses in the sagebrush biome New tools for a growing threat: Co-developed science informs the fight against invasive grasses in the sagebrush biome
In a new study, FORT scientists worked with resource managers to co-develop a strategic framework for invasive grass management across the sagebrush biome. The framework, implemented through computer simulation models, can help resource managers explore the efficacy of invasive grass management strategies and develop informed, economic conservation plans.

New study on the economics of public land treatments reveals treatment characteristics influence costs New study on the economics of public land treatments reveals treatment characteristics influence costs
Limited information exists on the costs of public land treatments, such as controlling flammable weeds and conducting prescribed burns, but managers can pair cost information with effectiveness data to improve decision making. In a new study, researchers used data from the BLM/USGS Land Treatment Digital Library to develop land treatment cost estimates.

Ecological benefits and risks of fuel breaks vary across the sagebrush biome Ecological benefits and risks of fuel breaks vary across the sagebrush biome
Fuel breaks – strips of land managed for reduced flammability – are designed to aid wildfire suppression and management. However, construction of fuel breaks may reduce wildlife habitat and introduce invasive species to ecosystems. In a new study published in Fire Ecology, USGS and Colorado State University researchers investigated these potential trade-offs of fuel breaks in sagebrush ecosystems.

Considering current ecosystem condition in restoration planning Considering current ecosystem condition in restoration planning
Restoration planning requires managers to weigh the potential benefits and costs of restoration action at a site. Sometimes, managers use structured, mathematical algorithms to decide where to focus restoration efforts. However, these algorithms do not always consider the current condition of ecosystems, instead focusing on the potential value of the resulting (desired) ecosystem.
