Big Island Pond Exotic Species Management Plan
Presented by:Jody ConnorDES Limnology Center Director
Exotic Plants In Big Island Pond
Fanwort Dates back to at least 1970s
Variable milfoil Dates back to approximately 2002

Variable milfoilVariable milfoil
This area is the primary variable milfoil infestation in Big Island Pond
The whole area in pinkis about 74 acres
Dots in pink area are actual milfoil colonies in 2007
Remapping in 2008 will likely reduce this overall area to a more specific footprint for control
A Quick Summary of Activities
Several meetings and e-mails with BIPC directors
Field visits in 2003, 2004, 2005 by DES biologists for mapping and hand-pulling
Field mapping in fall 2007 for current map/footprint
Preparation of a DRAFT Long-Term Management Plan for BIP
Elements of Long-Term Management Plan
Summary of information about infestations within BIP
Overview of lake ecology/biology/etc.
Establishment of goals Evaluation of treatment options 5-year plan/scenario for control
Goals
Contain further spread of variable milfoil
Eventual eradication of variable milfoil from the lake through the use of an integrated plant management approach
No control of fanwort

2013 Update and revise Long-Term Variable Milfoil Control Plan NH DES, F&G, and interested parties
Spring 2012
Year Management Strategy Responsible Party Schedule
The Plan (Basically)
2008 Fragment barrier (sometime the week of July 14 or 21) Re-mapping in August or September
2009 Herbicide treatment w/ 2,4-D on larger/thicker patches Hand-pulling single stems/small patches
2010 and beyond Hand-pulling Diver-assisted suction harvesting Monitoring/Evaluation
Weed Watching every year, monthly for any new growths!
