Bret Callaway

Environmental Scientist

Bret Callaway is a biologist who joined WEST in 2015. He received his B.S. in Environmental Studies and Master of Environmental Science and Management from the University of California, Santa Barbara in 2009 and 2014, respectively. Bret’s graduate research focused on estimating the impacts of beaver reintroduction on fish, wildlife and water resources in the Jemez River watershed in New Mexico.

As an environmental scientist at WEST, Bret is lead author and technical consultant for NEPA documents related to wildlife and water resources. To date, he has conducted literature reviews in support of state agency wildlife management plans, evaluated the impacts of reintroducing grizzly bears and wolves to their historic ranges on federal lands, drafted conservation agreements that incentivize private landowners to take voluntary measures that protect species of concern such as sage grouse, and written several bird and bat conservation strategies for wind farms. Currently, he is compiling a variety of technical reports into an Environmental Impact Statement (EIS) for a proposed water storage project for the City of Fort Collins, CO. In addition, he is working with project subcontractors to develop methodology for evaluating how the alteration of local hydrology, resulting from the project and its alternatives, will impact wetland and riparian vegetation.

Prior to WEST, he worked to develop agency rules and guidance for water quality trading programs throughout the Pacific Northwest. Prior to graduate studies, Bret worked as a botanist at both Yosemite National Park and Hawaii Volcanoes National Park, as a biologist for private environmental consulting firms, and as a restoration specialist for a non-profit organization. Bret’s areas of expertise include natural resource management, compliance writing, GIS analysis, and hydrologic modeling.
