Maintenance Action Teams

What are Maintenance Action Teams?

Maintenance Action Teams (MATs) are led by experienced trades professionals who train and complement Wage Grade Professional crews to perform critical maintenance and repair services on public lands managed by the National Park Service (NPS) and the U.S. Fish and Wildlife Service (FWS).

With funding from the Great American Outdoors Act (GAOA) National Parks and Public Land Legacy Restoration Fund (LRF), MATs perform deferred maintenance and repair (DM&R) work at national parks and national wildlife refuges across the United States. As part of this DM&R work, MATs also provide training and networking opportunities to public lands employees and partnership organizations. MATs consist of in-house wage-grade professionals across a variety of trades, including heavy equipment operation, electrical, plumbing, carpentry, masonry, and historic preservation.

MAT teams are based at field stations throughout the country and mobilized regionally and nationally to improve their skills while performing critical DM&R activities. Examples of MAT activities include earthwork, water management, trail repair, historic preservation, and constructed real property related rehabilitation activities.

In the first three years of GAOA funding, NPS is authorized to use $34.1 million for MAT activities and FWS is authorized to use $13.7 million.

Upon completion of MAT activities, maintenance professionals will be better able to properly maintain assets and critical systems, which will help to extend their lifecycle and alleviate the need for unscheduled emergency repairs or comprehensive rehabilitation after years of declining condition.
