From Vision to Law
With the support of key legislators including Senator George Mitchell of Maine and Representative Silvio Conte of Massachusetts, the North American Wetlands Conservation Act was introduced and passed by both chambers in 1989. President George H.W. Bush signed NAWCA into law on December 13, 1989, and pledged a federal policy of "no net loss of wetlands," a bold commitment to halting the rapid disappearance of these vital ecosystems across the continent.
How NAWCA Works
NAWCA authorizes federal grants, administered by the U.S. Fish and Wildlife Service, to fund projects that protect, restore, and enhance wetlands and associated uplands across the United States, Canada, and México. All grants require at least a 1:1 match from non-federal partners, catalyzing public-private collaboration among states, provinces, tribes, nonprofits, private landowners, and corporations. A nine-member North American Wetlands Conservation Council reviews proposals and awards funding twice a year, prioritizing projects aligned with NAWMP's goals for waterfowl populations and habitats.
Four Decades of Impact
NAWCA's true power lies in its multiplier effect: Since 1991, over $2.28 billion in federal grants have leveraged more than $4.53 billion in matching contributions, fueling over 3,300 projects that have conserved, restored, or enhanced upwards of 32.6 million acres of wetlands and related habitats across North America.
This isn't just about numbers. It's about real, landscape-scale impact. In the U.S. alone, NAWCA has touched every state, safeguarding breeding grounds in the Prairie Pothole Region, wintering refuges along the Gulf Coast, and stopover sites in the Mississippi Flyway. Extending to Canada and Mexico, the Act has funded boreal forest protection, coastal mangrove restoration, and highland wetland conservation vital to migratory routes.
For waterfowl and broader wildlife, NAWCA's value is massive. It has directly bolstered populations of ducks, geese, and swans by preserving the wetlands they depend on for breeding, nesting, feeding, and migration — reversing declines that prompted NAWMP's creation. Beyond birds, these projects benefit over 700 other species, from fish and amphibians to mammals like moose and otters, while filtering pollutants, recharging aquifers, and providing natural buffers against floods and storms. Economically, they support hunting, birdwatching, and outdoor recreation industries worth billions annually, creating jobs and enhancing community resilience. As climate change intensifies threats such as sea-level rise and drought, NAWCA's adaptive, partnership-driven approach ensures ongoing relevance, with recent funding rounds, such as the $102.9 million approved in 2024, continuing to build on this legacy. In essence, NAWCA transformed a visionary plan into an actionable triumph, proving that targeted investment and cross-border unity can secure a thriving future for North America's wetlands and the wildlife they sustain.
