Welcome to the Forest Service - National Stream & Aquatic Ecology Center.

The focus of the National Stream and Aquatic Ecology Center is on developing tools and science applications for the more effective management and conservation of watersheds, streams, riparian ecosystems, fisheries and aquatic ecosystems on National Forests and Grasslands.

Biological and Physical Resources program combined two of its Technical Units: the Stream Systems Technology Center and the Fish and Aquatic Ecology Unit. An executive Steering Committee and new Charter were developed to guide the integration of the units.
