About PAMF

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.

The video below is the first part of our three-part How PAMF Works video series which explains the background and issues that led to the creation of PAMF, what participation in the framework means, and how participant information is used to generate management guidance.

PAMF 2020-2026 Strategic Plan 

This strategic plan will guide successful implementation of PAMF by setting program-specific goals, objectives, and measures for the next five years. The PAMF core science team that developed the plan includes representatives from the Great Lakes Commission, U.S. Geological Survey, and University of Georgia. The core science team will evaluate the status of PAMF annually against this strategic plan. Unless otherwise stated, the plan goals, objectives, and measures are designed to be achieved at the end of the five-year plan period, and overall progress will be measured at the end of the 2025/26 PAMF cycle.
