The National Association of Wetland Managers (NAWM) was founded by Jon A. Kusler, Esq., Ph.D., and Scott Hausmann in 1983 with two goals — to support state wetland programs and to support national wetland policy reflecting sound wetland science. NAWM has tried to stay true to these goals throughout the years, during the ups and downs of funding and politics.

Jon and Scott created the Association with no staff and no budget. NAWM’s first national meeting in 1983 was hosted by Richard Haman and the University of Florida College of Law. To their surprise and delight, over 120 wetland managers and scientists attended. The quality and enthusiasm of the attendees was striking. Most did not know each other prior to the meeting but many emerged friends. Many who attended that first meeting in Florida also continue as wetland advocates and mentors.

This was the first of many workshops NAWM conducted with a broad range of federal agencies such as the U.S. Environmental Protection Agency, U.S. Fish and Wildlife Service, National Oceanic and Atmospheric Administration, Natural Resources Conservation Service, and the U.S. Army Corps of Engineers. Other partners have included the Association of State Floodplain Managers, Society of Wetland Scientists, Association of Clean Water Administrators, Coastal States Organization, National Association of Fish and Wildlife Agencies, and the Environmental Law Institute.

Hundreds of symposia, workshops, publications, webpages, and webinars later, NAWM has established a national presence and is looked to by states, tribes, and other organizations for leadership in matters of national wetland policy, applying sound science, interpreting and implementing the Clean Water Act and related programs, restoring aquatic systems, and facilitating transfer of knowledge among peers and government agencies.

Scaling Wetland Intelligence with GeoAI: Tools, Trends, and a National Vision

Held Thursday, January 29, 2026 - 3:00-4:30 p.m. EST

View Recorded Webinar 

INTRODUCTION

• Portia Osborne, National Association of Wetland Mangers [PDF Presentation]

PRESENTERS

• Sunny Fleming, Esri [PDF Presentation]
• Andy Carroll, Skytec 

ABSTRACT 

The National Wetlands Inventory (NWI) is the most authoritative national dataset for wetlands, yet in many areas its coverage is decades old. Recent policy changes, including the Sackett v. EPA decision, place greater responsibility on states to develop strategies for protecting wetland resources. This webinar you learned how the state of Tennessee partnered with Skytec to enhance Esri’s Wetland Identification Model (WIM) with advanced GeoAI and cloud computing to produce more accurate, scalable wetland predictions. They also covered tools to help states get started, how these efforts align with emerging policy trends, and a vision for scaling this approach nationally. You will see how these innovations help states make informed, data-driven decisions for conservation, permitting, and land-use planning.
