Weed Watcher Program ID's and Helps Eradicate Aquatic Invasive Weeds

The Weed Watcher program is a State of NH Dept of Environmental Services program to identify aquatic invasive weeds, prevent their spread, and coordinate eradication.


What Weed Watchers Do

Weed Watcher monitoring on Lake Armington happens once a month, May through late August, along the shoreline from boats, canoes or kayaks using specially-made view-scopes. To join the Weed Watcher team contact Evie Conroy.


What You Can Do - right from your cottage

You can monitor aquatic invasive weeds and species along your shoreline and around your dock or float, then alert Evie Conroy or a Weed Watcher team member.  Use the Photo ID links below.

Common Reed (Phagmites) Eradication Report - Sept. 4, 2014

Brad Caswell's Common Reed Eradication project summary and recommendations are available here. A good read on a critical project.


Common Reed (Phragmites) Eradication Project History

The first phase of Common Reed eradication by an outside company took place in September 2012 as planned. A second area has been identified nearby and will be handled as a separate project, and Brad Caswell is overseeing both. The Common Reed infestation was first positively identified in 2009 by the Department of Environmental Services (DES).


Eradication by hand (!) began in the fall of 2011 in an area on the eastern shoreline where a highly invasive exotic weed, the Common Reed, had taken hold was was spreading well beyond the original area.


In early 2012 LAA board hired a company specializing in weed eradication to eliminate the Common Reed (Phragmites) over a three-year period costing several thousand dollars.
