What are Maintenance Action Teams?

Funded through the Great American Outdoors Act National Parks and Public Land Legacy Restoration Fund (GAOA LRF), Maintenance Action Teams (MATs) consist of in-house the National Park Service (NPS) and the U.S. Fish and Wildlife Service (FWS) staff who can quickly mobilize to perform smaller, yet critical deferred maintenance and repair (DM&R) work at national parks and national wildlife refuges across the country.

MATs are composed of NPS and FWS staff trained in a variety of trades, including heavy equipment operation, electrical, plumbing, carpentry, masonry, historic preservation, and more. Teams can quickly mobilize to tackle smaller maintenance and repair needs. Examples of MAT activity work include trail repair, earthwork, water management, building component renewal, stone masonry, and hazard tree removal.

In the first five years of funding, the U.S. Department of the Interior (Interior) directed $84 million of the GAOA LRF for NPS
MAT activities and $52 million for FWS MAT activities.

Benefits of Maintenance Action Teams

MATs serve a critical role in addressing DM&R needs across the country to keep public lands sites safe and enjoyable for all visitors, staff, and volunteers. MATs take on smaller activities by dispatching teams of specialists across a geography without creating redundant positions at every site.

Maintenance Action Team Benefits

Training the Next Generation

MATs are teaching specialized skills to a new generation of trade, preservation, and facility specialists and public land stewards. MATs serve as a valuable training ground for in-house knowledge, skill, and expertise. By bringing together MAT staff with a variety of skill sets who support a broad range of repair work, MAT staff can learn on-the-ground from each other about the foundations of a trade that will prepare them for a future career in the field.

Efficiency

NPS and FWS can rapidly mobilize MATs to address DM&R needs across the country. Because MATs are composed of in-house FWS and NPS staff, teams are nimble and rapidly mobilize to respond to maintenance needs, minimizing administrative costs and set-up times. Since MATs are geographically based, they can reduce the need for redundant specialized skill sets at sites within the same area. In addition, MATs do not require procurement or contract awards, streamlining and reducing the time to deploy.
Partnership and Collaboration

Partnership and Collaboration

MATs provide opportunities to partner with a variety of programs and organizations. Many MAT activities at NPS collaborate with local workforce development programs, such as youth conservation corps, veteran service corps, and public lands corps, as well as with NPS volunteers and interns, to execute maintenance work. In addition, MATs collaborate with existing bureau programs at Interior to complete more specialized MAT activities. For example, MATs can deploy NPS’s Historic Preservation Training Center teams to complete historic preservation-focused MAT activities.

Ability to Perform Work in Remote Places

MATs help address DM&R needs at sites in remote locations. Because MATs are flexible and regionally based, teams can perform work in locations where the costs of mobilizing third-party construction contractors may otherwise be prohibitive, allowing GAOA LRF funding to address DM&R needs even at difficult to reach locations.

Wide Reach

MATs perform activities across the country to improve a wide range of public lands sites. MATs address smaller DM&R needs at national parks and national wildlife refuges, allowing the majority of GAOA LRF funding to be used for large scale projects that are otherwise out of reach with annual appropriations. The ability of MATs to conduct DM&R work at more sites broadens the scope and benefits of the GAOA LRF program across the country.
