About Sarah

Sarah Marshall has more than 15 years of professional experience in hydrology and ecology, with an emphasis on assessing, conserving and restoring wetlands and streams in Oregon and Colorado. Her doctoral work in Water Resources Engineering focused on understanding the effects of land use on wetland hydrology, ecology, and water quality across different spatial scales, and she has since applied her training to a diverse array of projects. In the university classroom, she has developed and taught courses in nonpoint source pollution and soil science. As a consultant and contractor for the NRCS, she designed wetland restoration projects, conducted wetland monitoring, developed management plans for federal wetland conservation easements, and worked extensively with NEPA and Clean Water Act wetland permitting. As a research associate with the Colorado Natural Heritage Program (CNHP), Sarah divides her time between field research and helping translate field and modeling data into tools and resources designed to support wetland conservation and restoration activities across Colorado and the West. Sarah currently leads projects to evaluate wetland and riparian ecosystems and expand the Colorado Watershed Planning Toolbox in the Roaring Fork watershed, monitor alpine sites for the National Park Service as part of the Global Observation Research Initiative in Alpine Environments (GLORIA) climate change study, develop an online wetland and riparian restoration database for Colorado, and restore a riparian area along Rifle Creek on Colorado’s Western Slope.
