  1. Big Island Pond Exotic Species Management Plan Presented by: Jody Connor DES Limnology Center Director

  2. Exotic Plants In Big Island Pond • Fanwort • Dates back to at least 1970s • Variable milfoil • Dates back to approximately 2002

  3. Fanwort

  4. Variable milfoil

  5. This area is the primary variable milfoil infestation in Big Island Pond The whole area in pink is 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

  6. 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

  7. 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

  8. 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

  9. Evaluation of Control Options

  10. RECOMMENDED EXOTIC AQUATIC PLANT CONTROL 5-YEAR PLAN FOR BIG ISLAND POND

  11. RECOMMENDED EXOTIC AQUATIC PLANT CONTROL 5-YEAR PLAN FOR BIG ISLAND POND Year Management Strategy Responsible Party Schedule

  12. 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!

  13. What You Need to Do • Send in a formal request for funding to Amy Smagula • All information you need is online at http://www.des.state.nh.us/wmb/exoticspecies/grants • Formal request due September 15th for matching funds • DES will notify BIP of grant availability/amount by November 30th • Need bids from applicators • BIP contacts applicators requesting bids- PLEASE WAIT FOR UPDATED MAP FROM DES IN AUGUST/SEPTEMBER • Contact towns around pond and see if they would contribute any funding • Raise funding for your match

  14. Questions? For more specific information relative to this control/management process, please contact: Amy P. Smagula Exotic Species Program Coordinator 29 Hazen Drive Concord, NH 03301 603-271-2248 Amy.Smagula@des.nh.gov
