Drained Without a Record: The Millions of Wetland Acres America's Monitoring Systems Cannot See
Federal wetland protections depend on accurate maps, but spatial analysis reveals that millions of acres of converted wetlands have slipped through jurisdictional cracks before monitoring systems could record them.

The cost to American taxpayers—measured in lost flood mitigation, water filtration, and carbon sequestration—runs into the billions.
