Mission Areas L2 Landing Page Tabs

The Ecosystems Mission Area provides impartial science information and tools to the Nation’s natural resource managers, with particular focus on the science needs of the Department of the Interior (DOI) and DOI bureaus to manage species, lands and priority ecosystems; fulfill treaty obligations; respond to and reduce threats to natural resources; and manage mineral and energy resources.

Scientists with the Ecosystem Mission Area can be found working across the Nation to provide fish, wildlife, and habitat science support to natural resource managers. Our sixteen Ecosystem Science Centers provide unique scientific capabilities to support the management and conservation of our Nation’s biological resources.
