Department of Defense Legacy Resource Management Program

EFTA Texas Do D survey Mercy

The Department of Defense Legacy Resource Management Program (DoD Legacy Program) is partnering with the U.S. Forest Service International Programs to support DoD in monarch butterfly conservation. Programs aim to help DoD land managers maximize the use of their lands for training while considering the needs of this widespread at-risk species.

General areas of support include:

  • Identifying priority areas for monarch conservation on DoD lands
  • Providing baseline data on monarch habitat and populations through both on-the-ground and remote studies
  • Developing and distributing best management practices for habitat management, inventory and monitoring, and other needs
  • Responding to DoD inquiries

Program Partners

  • Monarch Joint Venture
  • Xerces Society
  • California Association of Resource Conservation Districts (CARCD)
  • Environment for the Americas
  • Washington State University
  • University of California Davis
  • James Madison University

Priority Monarch Conservation Areas for the West

  • Overwintering sites
  • Central Valley of California

Priority Monarch Conservation Areas for East

  • North Core and South Core Conservation Units


The South Core and North Core areas were chosen as priority conservation units due to their designation by the Midwest Association of Fish and Wildlife Agencies. Approximately 80% of the total eastern migratory monarch population is estimated to come from the northern range of the eastern monarch population (Flockhart et al. 2017), an area approximating the North Core and north exterior monarch conservation units as described by the USFWS in the above figure.

The South Core provides an essential breeding habitat for monarchs arriving from Mexico in the spring. Additionally, it provides essential nectar plants for migrating monarchs in the spring and fall of each year. Data (Flockhart et al. 2013) suggest that fall monarch reproduction in the Southern Great Plains may contribute to the wintering population in Mexico. For more information about monarch conservation priorities, please see the Midwest Association of Fish and Wildlife Agencies. 2023. 2023 Update to the Mid-America Monarch Conservation Strategy, 2018-2038; Mid-America Monarch Conservation Strategy.
