Joint Base Lewis McChord Sentinel Landscape

  • Washington

  • Established 2013


The Joint Base Lewis McChord (JBLM) Sentinel Landscape hosts the third largest installation in the U.S. Army, which is home to 43,000 soldiers and airmen. The sentinel landscape also supports the majority of the remaining native prairie habitat in Washington’s south Puget Sound. Once extending over 150,000 acres, this critical ecological asset now covers only 23,000 acres, 90 percent of which is located on JBLM. As a result, multiple species listed under the Endangered Species Act that depend on prairie habitat—such as the Taylor’s checkerspot butterfly, the streaked horned lark, and the Mazama pocket gopher—seek refuge on the installation. Since receiving designation in 2013, JBLM Sentinel Landscape partners have worked closely with private landowners to enact conservation measures aimed at strengthening military readiness through the recovery of threatened and endangered species.

Partnership Highlights

Strengthening Military Readiness through Endangered Species Recovery

Joint Base Lewis McChord Sentinel Landscape partners have worked together to alleviate environmental training restrictions on the U.S. Army and Air Force by supporting the recovery of the endangered Taylor’s checkerspot butterfly. In 2007, sentinel landscape partners introduced the butterfly onto a permanently protected property adjacent to JBLM where conservation efforts had been underway to restore the butterfly’s native prairie habitat. These efforts culminated in 2013, when the Taylor’s checkerspot butterfly population increased significantly and expanded its boundaries beyond the original introduction point. Building off this success, JBLM and the U.S. Fish and Wildlife Service are now working together to develop a formal species-crediting strategy that will ease Endangered Species Act- related restrictions on the installation.

Advancing Conservation Opportunities on Agricultural Lands

In 2018, a research collaborative of sentinel landscape partners, including Thurston County, the Center for Natural Lands Management, and Washington State University, received a grant from the U.S. Department of Agriculture’s s Western Sustainable Agriculture Research and Education Institution to evaluate how agricultural practices can improve the conservation value of working lands for prairie ecosystems. The objective of the project is to quantify the ecological benefits associated with such practices, and thereby increase opportunities for working landowners to receive technical or financial assistance related to habitat management.

“Thurston Conservation District supports the mission of the Joint Base Lewis-McChord Sentinel Landscape because it embodies the mission and values of our organization – to work with private landowners and partners to protect our vital agricultural economy, while conserving endangered species habitat. Engaging our military community in agricultural and conservation efforts in our region provides a strong pipeline of stewards of our South Puget Sound’s valuable natural resources, while also ensuring our that these important landscapes are preserved for future generations. We value the inclusion of our local landowner and agricultural community in our local Sentinel Landscape, where their needs and barriers are included in project development and execution. This is critical to the success our region’s shared goals!”
