Non-native Phragmites australis is one of the most aggressive plant species invading North America and is already well established in the Great Lakes basin, along the Atlantic, Pacific, and Gulf Coasts, and around the Great Salt Lake. More about Phragmites can be found here.

Non-native Phragmites is managed using a suite of conventional approaches (e.g., herbicide, cutting/crushing, flooding, burning), but these approaches aren’t getting the job done at the landscape scale. They are resource intensive and differ in effectiveness, largely because there are uncertainties about how the plant responds to treatment given site-specific conditions and variations in how managers apply treatments.  In addition, it is difficult to coordinate management efforts across the landscape and learn from each approach used.

To address these challenges, the Great Lakes Phragmites Collaborative is developing an adaptive management strategy called The Phragmites Adaptive Management Framework (PAMF). This framework will change the way Phragmites management is done throughout the Great Lakes basin and lead to approaches that maximize the effectiveness and efficiency of Phragmites management.

PAMF is being developed by a Core Science Team composed of researchers and staff at the USGS, University of Georgia, and the Great Lakes Commission. The Core Science Team works closely with the Technical Working Group (TWG), which is made up of 12 professionals from across the basin who are considered experts in Phragmites management. Involving the TWG at an early stage has ensured different stakeholder values, priorities, and perspectives have been included throughout the development of PAMF and the framework reflects the needs and objectives of users.

Technical Working Group

The PAMF Technical Working Group is have been integral to the development of the framework. These individuals have volunteered their time and offered their advice and expertise; PAMF could not exist without them.
