The economic and environmental impact of aquatic invasive species (AIS) within the Columbia River Basin (CRB) can be significantly reduced through a coordinated research and monitoring effort designed to solve management problems.  This web-site provides a wide range of biological and physical information required by researchers and managers to develop new ways of eliminating or reducing the impact of AIS throughout the CRB in a changing climate.
