Plant Control


Variable-leaf Milfoil exists in Pleasant Pond, Horseshoe Pond and parts of Purgatory and Cobbossee Streams; 44 water bodies in Maine suffer from an infestation of a non-native aquatic plant.  Since 2005, buoy markers, hand removal and "milfoil mats" projects have had some success on overall removal results.  In December 2009 Pleasant Pond was one of seven "test bed" lakes to receive funding from the Maine Milfoil Initiative, a consortium that was awarded $500,000 from the US Fish and Wildlife Service to fight invasive milfoil in Maine.  

In 2010, the Friends built a Diver Assisted Suction Harvester (DASH) unit to manage the population of invasive plants in Cobbossee Watershed waters.  The 2012 DASH harvesting season was a successful one, with over 11,400 gallons of variable leaf milfoil removed from Cobbossee Stream, Horseshoe Pond and Upper Pleasant Pond.  For a look at the level of infestation in these waters, along with exactly where we harvested in 2012, please check out the 2012 Survey & Harvesting Map, below!
