Biological Studies

Federal law requires biological studies for the Environmental Impact Statement (EIS) process and to comply with the Endangered Species Act.

Congress created the Endangered Species Act to help conserve the ecosystems that support endangered and threatened species and to provide conservation programs for those species.

The studies will include data and reports gathered by outside organizations, including:
