## What We Do

#### Our Services

The Habitat and Population Evaluation Team (HAPET) is part of the National Wildlife Refuge System of the U.S. Fish and Wildlife Service (Service). The HAPET office supports the conservation mission of the Service by integrating scientific data and landscape-scale conservation planning with a focus on migratory birds. This enables the Service to more effectively conserve and manage wildlife and their habitats for the U.S. Fish and Wildlife Service and conservation partners.
