Marni Koopman, PhD, Climate Change Scientist

MarniKoopmanMarni takes a lead role in developing and executing ClimateWise® projects to help local communities and federal land managers prepare for a changing climate. She brings communities the science they need to make informed decisions and walks them through a process that results in climate change strategies that are integrated across both natural and human communities.  Marni has also worked on developing climate-informed conservation blueprints for the Klamath-Siskiyou ecoregion and the Colorado Plateau.  Marni joined the Geos Institute's staff after completing postdoctoral research with the Forest Service’s Rocky Mountain Research Station. That research investigated the effects of climate change on wildlife and wildlife habitat by working with a team to model climate stress and assess the level of state planning for climate change in the State Wildlife Action Plans. Marni has expertise in climate change effects on wildlife, ornithology, metapopulation ecology, conservation genetics, and invasive species.  Marni holds a B.A. in Environmental Studies from the University of California at Santa Barbara, a M.S. in Wildland Resource Science from the University of California at Berkeley, and a Ph.D. in Ecology from the University of Wyoming.

Brian Barr, MS, Aquatic Habitat Restoration Project Manager

BrianBarrBrian Barr is an aquatic ecologist with over 16 years of experience on trout and salmon restoration in the Pacific and intermountain west. He holds a bachelor’s degree in zoology from Miami University and a master’s degree in fisheries and wildlife science from Virginia Tech. Over the past nine years, Brian has focused his attention on improving fish passage conditions in the Rogue and Klamath Rivers of southern Oregon and northern California, restoring river, floodplain, and streambank conditions,  and assessing the effects of livestock grazing on creeks and springs in the Cascade-Siskiyou National Monument. Recently, he has turned his attention to the emerging impacts of climate change, how those impacts are likely to affect communities and natural resources, and what we can do to prepare ourselves and the resources we depend upon to withstand these effects. In his off time, Brian fishes, watches his daughter ride horses, and bites his fingernails during Virginia Tech football games.
