Rivers and streams provide both habitat and migration corridors to a myriad of species, including plants, fishes, amphibians, birds, mammals, and insects. Beginning in 2003, states in the Northeast started integrating ecological principles in management plans to protect imperiled species and aquatic biodiversity. More recently, states have started considering the impacts of climate change and the role of habitat heterogeneity in an effort to promote biodiversity in the face of a changing climate. However, none of these frameworks define biodiversity metrics, incorporate climate change specifically, nor evaluate alternate management scenarios. Therefore, the DOI Northeast Climate Adaptation Science Center (CASC) has funded a project that will incorporate CASC products on climate change and
