We Need Your Help:  Eurasian watermilfoil (EWM) is overtaking the Fall River

The Fall River Partnership—Fall River Conservancy, California Trout, and the Fall River Resource Conservation District—have joined forces to develop a viable strategy for managing Eurasian watermilfoil (EWM).   In the summer of 2011, this partnership will carry out a two year pilot project that uses a biological control—the milfoil weevil—to systematically reduce the spread of EWM.

The milfoil weevil, Euhrychiopsis lecontei, is a small aquatic weevil that lives and feeds only on EWM. Once introduced, milfoil weevils eat away at EWM until populations decline to manageable levels.

Milfoil weevils do not negatively affect fish populations, native aquatic vegetation, agricultural crops, or any other sensitive species in the Fall River Valley –including people.

Cost Estimate

The Fall River Partnership mentioned above is working together to raise $125,000 to implement a two year pilot program for managing EWM in the Fall River.  Money raised will go towards working with EnviroScience Inc. to propagate a biological control (weevils), distribute the weevils in strategic locations throughout the river, and then monitor the results to ensure that the intended impact occurs.

After two years, we’ll monitor the impact of the program to determine whether additional resources should be invested in the program.  The California Department of Fish and Game, the U.S. Department of Agriculture, and the Regional Water Quality Control Board will provide regulatory oversight and guidance to ensure that all necessary permits and procedures are followed.

The Fall River Partnership is currently working with the USDA and PG&E to secure partial funding for this project.   But we also need private support and individual donations to meet our funding goals and demonstrate that we have local support from the community.

Please donate now to support this program.

Community Approach

The Fall River Partnership believes in working within the community to constructively solve problems and in taking personal responsibility for managing the extraordinary natural resources of the Fall River Valley.  Although Fall River stakeholders differ significantly in demographics, we share a common interest in the general economic, cultural and ecological well-being of the valley.

EWM threatens this common interest.  Please help our community address this problem by making a donation today.

This project originated from the ground up: from within our community. Your donation demonstrates that we as community can solve problems using non-adversarial strategies.

Thank you for joining our cause.
