Big Island Pond: A Green Approach to Eradicating Variable Milfoil
Location
A group of concerned residents of Big Island Pond formed a non-profit organization dedicated to financing significant initiatives for weed control, and water testing to preserve and protect water quality and habitat, to educate and promote stewardship of these resources and to act as an advocate for sound environmental policies and practices, using a nonchemical approach.

Innovation
What makes your idea unique?
Variable milfoil, an exotic weed species has threatened the rich diversity of plant and animal species found in Big Island Pond. Last year, residents chose not to use chemical herbicide treatment in over 50 acres of this 528 acre lake. Variable milfoil can spread exponentially in a lake because it establishes quickly from fragments. The result is that, in densely growing areas of milfoil growth, oxygen is depleted in the water, and biotic elements are reduced over time.
In 2009, members of the Board of Directors of Big Island Pond Corporation, which owns the water rights to the lake, chose not to use the chemical herbicide 2,4D in treating the affected areas of Big Island Pond. A concerned group of resident conservationists stepped in to organize the spring and summer effort to reduce the infestation of milfoil using diver assisted suction harvesting and hand pulling.
With a grant from the French Foundation, several residents redesigned a pontoon boat into a 24 foot diver assisted suction harvester. A smaller privately owned diver assisted suction harvester was also built to access areas in shallow water and around boats where the large “Milfoiler” could not reach. A crew of scuba divers were certified through the N.H. Department of Environmental Services and scheduled up to 12 dives a week in an effort to reduce the density of milfoil in the identified coves on the lake. At each dive, volunteers in kayaks offered top support to the divers. Residents of the lake provided food for the divers during the weekend dives.
This program is unique in that the chemical application has been the most widely used treatment for variable milfoil. With concern for the short and long term toxic effects of a chemical herbicide, a formidable volunteer and educational effort was undertaken to remove milfoil from Big Island Pond

Impact

What impact have you had?
The use of diver assisted suction harvesting and lake monitoring without the additional use of chemical herbicides to mitigate the growth of variable milfoil in a lake system has social impact for the residents of the lake living in three different towns as well as the businesses and citizens who use Big Island Pond as a source of income and recreation.
Because variable milfoil reduces biodiversity and water quality in a short period of time, value of homes on the lake and recreational uses of the lake are endangered.
The choice not to use a chemical herbicide was a critical point for the resident community. This decision led to the establishment of a non-profit organization committed to the promotion of stewardship of the lake. Moving the milfoil management program forward required support of residents and the Big Island Pond Corporation, which owns the water rights and dam on the lake.
Moving forward with milfoil management galvanized an outpouring of volunteer support. This support included the design and building of a 24 foot suction harvester, the training of scuba divers, the establishment of a group of residents to look for and monitor the presence of milfoil in coves around the lake, and a substantial effort to support the dive program with individuals who provided top support, facilities and food for the teams throughout the twelve harvesting dives each week from May through September.
Throughout this process, there was a concerted effort to raise awareness of ways in which residents, boaters, and fishermen could assist in reducing the spread of milfoil into areas of the lake so far untouched by variable milfoil.
Problem
The primary problem that the use on non-chemical suction harvesting of milfoil is addressing is to reduce the presence of the variable milfoil, an exotic weed species, in Big Island Pond. Variable milfoil threatens the rich biodiversity of plant and animal species and the water quality of Big Island Pond by choking the oxygen supply in the water and upsetting the natural balance of phosphorus and minerals in the lake.
Actions
Steps that have been taken to make this innovation a success have included:
1) the formation of Friends of Big Island Pond (FBIP), a non-profit organization dedicated to financing significant initiatives for weed control.
2) 2009 Weed Management Program of suction harvesting, lake monitoring, and educational programming
Results
The result of our first year of suction harvesting in 2009 was very productive and encouraging. Areas of dense growth were reduced significantly. We were able to use GPS technology to identify areas of growth and categorize these areas based on density. This density mapping is the baseline for the suction harvesting operations.
What will it take for your project to be successful over the next three years? Please address each year separately, if possible.
We understand that milfoil, once introduced into a lake ecosystem, will require many years of management and monitoring. It is important that we continue to robustly attack areas of current infestation and that areas already harvested be rechecked for new growth. The nature of the milfoil plant is such that it fragments easily and establishes new growth with fragments in addition to new growth through seed production. Boat propellers, fishing, wind, and current action continue to disperse milfoil resulting in exponential growth. We are aware that we will continually have to work at mitigating this threat to our lake ecosystem.
Over the next three years, we will continue to seek grant funding and other fund raising opportunities to continue the harvesting program. At the same time, we will be continuing to education school children in the surrounding areas, residents, boaters, and fishermen concerning stewardship issues of Big Island Pond.
What would prevent your project from being a success?
Lack of funding for the expenses involved in suction harvesting would prevent us from being as successful as quickly as we would like to be. The nature of milfoil is that its growth is exponential. Without an all out effort to eradicate milfoil, its growth will be more formidable and expensive to control.

The Story
What was the defining moment that led you to this innovation?
The defining moment that led a group of concerned environmentalist-citizens to this non-chemical approach to a biological problem was the vote of the Board of Directors of Big Island Pond Corporation. Residents of the lake had grappled for two years with developing a solution to the mitigation of milfoil in the lake. This exotic species is spreading throughout most lakes in southern New Hampshire. We could not ignore the problem any longer and failure to address it would result in rampant establishment of this weed throughout the lake system.
A great deal of effort had been put into analyzing the problem, filing weed management plans with the NH Department of Environmental Services and many meetings of the Weed Management Oversight Committee since 2007. When it came time to vote an appropriation to contract with a firm to apply the herbicide, 2,4,D, the vote failed.
This galvanized a monumental effort to attack the problem in 'green' fashion through diver assisted suction harvesting and a broad based education program.
Tell us about the social innovator behind this idea.
No one individual is responsible for this effort. Rather a host of committed residents provided the leadership and volunteerism necessary to work through the 2009 milfoil control program.
