Secretarial Order 3362

Improving Habitat Quality in Western Big Game Winter Range and Migration Corridors

On February 9, 2018, at an event in Salt Lake City, Utah, the Secretary of the Interior signed Secretarial Order 3362, “Improving Habitat Quality in Western Big Game Winter Range and Migration Corridors”. The Order has attracted considerable attention and created momentum for management and conservation of migration corridors and winter range. As of May 2022, the Department of the Interior (Department) has entered Year 4 of implementation and our approach over the past two years has established the solid foundation necessary for successful future endeavors.

“Enhance and improve the quality of Rocky Mountain elk, mule deer, and pronghorn antelope winter range and migration corridor habitat.”

The Order is focused on species under the management authority of state fish and wildlife agencies, so it directs the appropriate bureaus within the Department to engage western states collaboratively and cooperatively. More directly, the Order recognizes state authority to manage big game species. The Department’s role in implementation stems from its management responsibility for millions of acres of land across the West, strong scientific and technical capabilities, and ability to bring forward other resources to help facilitate wildlife habitat conservation activities across multiple states. The Order is focused on conserving, enhancing, restoring, or improving the condition of priority big game winter range and migration corridor habitat. Ultimately, the habitat conservation activities resulting from the implementation of the Order will provide positive benefits to big game populations and numerous other wildlife species.

Overarching Philosophy, Vision, and Approach

Progress Reports

5-Year Progress Report, April 2024

Secretarial Order 3362 was signed in 2018 to emphasize the importance of conserving and improving elk, mule deer, and pronghorn antelope habitat. Each year, the BLM works cooperatively with state and Tribal governments, federal agencies, landowners, universities, conservation organizations, and others to improve millions of acres of fish, wildlife, and plant habitat degraded from wildland fire, drought, invasive weeds, and development on public lands. Much of this work directly benefits big game winter range and migration corridors.


In the last five years, the BLM has:

  • Removed or modified 1,250 miles of fencing to improve wildlife movement and migration,
  • Improved 3 million acres of big game wildlife habitat, and
  • Installed or maintained 1,150 water developments for use by big game animals and other wildlife.

Implementation Progress Report, August 2020

Partnerships have made meaningful progress on the implementation of the Order in the first 4 years. For example, over 50 research projects are funded and well over 170 habitat projects. Numerous other habitat projects are funded through other sources (i.e. NRCS programs) in state defined priority seasonal habitat and migration corridors.

Exceptional cooperation and collaboration with the states continues. Read about some our past  accomplishments in the 2020 Progress Report (PDF, 6 MB).


  • Funding Surpassed $30 million. The Department of the Interior and partners provided funding to support state-identified priority research projects, data analysis and mapping assistance, and for habitat-related projects.
  • SO 3362 Coordinator Hired by the US Fish & Wildlife Service in May 2018.
  • State-specific Action Plans were developed for each of the 11 western states by October 2019.
  • Bureau Liasions Established by the BLM, FWS, and NPS.

State-specific Action Plans

Action Plans provide focus, facilitate partnership development, inform grantmaking programs, and ultimately serve as a tool to accomplish habitat conservation.

The U.S. Geological Survey (USGS) works in close cooperation with the states, in particular the WAFWA and its program manager for the Crucial Habitat Assessment Tool (CHAT®) in developing maps or mapping tools related to elk, deer, or pronghorn movement or land use. A primary action taken my USGS in response to SO3362 was to assemble a Corridor Mapping Team to work with individual State wildlife agencies and partners to facilitate mapping of migration corridors. The Team has been in place since the beginning of 2019 and is based out of the Wyoming Cooperative Research Unit, but includes key biologists in participating State agencies.

Wildife Corridors and Route Viewer
Public access to data on migrating ungulates through a unique partnership between participating western states. This tool enables viewing of mapped migration corridors, routes, stopovers and ranges.

The USGS Migration Mapper™ is a free application designed for researchers, biologists, and managers, to analyze fine-scale GPS collar data collected from migratory ungulates.

NFWF Grant Program Improving Habitat Quality in Western Big Game Winter Range and Migration Corridors.
The The National Fish and Wildlife Foundation’s (NFWF) Improving Habitat Quality in Western Big Game and Migration Corridors Program aims to conserve critical winter range and migration corridors to maintain healthy populations of pronghorn, elk and mule deer, and the phenomenon of big game migration. The program is working with conservation partners across Arizona, California, Colorado, Idaho, Montana, Nevada, New Mexico, Oregon, Utah, Washington and Wyoming.

Bureau Liaisons

Liaisons are integral to the implementation of the Order, they serve as the point of contact with government and nongovernment partners at the local level within their assigned states. They conduct outreach to the public and work with the respective states to develop and update the Action Plans.
