Trust Species & Habitats


The Trust Species and Habitats (TSH) Branch of the Fort Collins Science Center (FORT) includes a diverse group of scientists encompassing both traditional and specialized expertise in wildlife biology, ecosystem ecology, quantitative ecology, disease ecology, molecular genetics, and stable isotope geochemistry. Using our expertise and collaborating with others around the world, our goal is to provide the information, tools, and technologies that our partners need to support conservation, management, and restoration of terrestrial vertebrate populations, habitats, and ecosystem function in a changing world.

Some of the biggest challenges facing wildlife today are changes to their environment from both natural and anthropogenic causes. Natural resource managers, planners, policy makers, industry and private landowners must make informed decisions and policies regarding management, conservation, and restoration of species, habitats, and ecosystem function in response to these changes. Specific needs include: (1) a better understanding of population status and trends, (2) understanding of species habitat needs and role in supporting ecosystem functions; (3) the ability to assess species’ response to environmental changes and predict future responses; and (4) the development of innovative techniques and tools to better understand, minimize or prevent any unintended consequences of environmental change. Read the Trust Species and Habitats Branch Fact Sheet to learn more.

Arid Lands Field Station

The Arid Lands Field Station is a part of the Trust Species and Habitats Branch of the USGS Fort Collins Science Center. Field station scientists conduct research on natural resource and wildlife issues, with particular emphasis on Southwestern ecosystems. Scientists have expertise on mammals, birds, and arthropods, including state and federally listed species and species of special management concern. They also conduct applied studies to address management issues related to ecosystem dynamics, species responses to natural and human-induced change, emergent wildlife diseases, and the Southwestern habitats that are important to these taxa.

The location of the Arid Lands Field Station at the University of New Mexico provides opportunities for academic partnerships with faculty,...
