How PAMF Works Video Series

The Phragmites Adaptive Management Framework (PAMF) was developed through the Great Lakes Phragmites Collaborative to change the way Phragmites management is done throughout the Great Lakes Basin and to help inform effective and efficient Phragmites management.

To find out more, view the three-part video series below that 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.

What is PAMF?

Video transcript and information on the U.S. Geological Survey website

From landowners to agencies, we have been fighting back against Phragmites for years, utilizing a variety of treatments options. Since the effectiveness of treatments relies heavily on-site conditions and infestation levels, the Great Lakes Phragmites Collaborative has recognized the need to facilitate a regional collective learning process which has developed into the Phragmites Adaptive Management Framework. PAMF has implemented this adaptive management framework to improve management efforts by learning and sharing what site-specific treatments have been working with managers across the basin.

PAMF has three critical pieces: a monitoring protocol, a learning model that predicts how Phragmites will respond to different management alternatives, and a central database with an associated Web Hub where the results from all management efforts are reported.

PAMF runs on an annual cycle. Managers like you can join PAMF year-round by enrolling a site on the Web Hub.  To enroll a site, establish the boundaries of your management unit and report basic site characteristics. Next, implement the standardized monitoring protocol and upload those data to the central database to determine your unit’s state of Phragmites infestation.  The predictive models will combine and analyze user-collected data and provide site-specific treatment guidance every year.  Participants implement a treatment of their choice, and the cycle repeats until Phragmites no longer grows on the site. Data provided by all of the participating land managers across the basin will fuel the adaptive management process.

The key to PAMF’s success is long-term and widespread participation by you – our partners – from around the Great Lakes basin.

The PAMF Model

PAMF utilizes a computer-based, predictive model that uses your data, along with data from other participants, to learn about Phragmites management throughout the basin—what management actions were taken and how well they worked. The model is run each August after all participant data have been submitted. By combining the model’s quantitative learning regarding Phragmites management with expected costs for various management actions, the model provides site-specific management guidance that is optimized to reduce Phragmites, while minimizing management costs.
