Lakefront property owners are encouraged to attend a free workshop on prevention and control of invasive aquatic plants in local lakes.

The free workshop, being held Saturday, June 14, from 8:45 a.m. to 2:30 p.m., is being coordinated by the Acton Wakefield Watersheds Alliance (AWWA) in partnership with the York County Invasive Aquatic Species Project and multiple lake associations from both states, according to AWWA Executive Director Linda Schier. Experts from the Maine Volunteer Lakes Monitoring Program and the NH Department of Environmental Services will cover how participants can prevent an invasive aquatic plant infestation in their own lakes.

The workshop will provide an overview of invasive species in Maine and New Hampshire, teach participants the tricks of identification fundamentals, and provide tools to conduct a screening survey. Samples of live invasive and native aquatic plants will be available for inspection and to assist with the plant identification exercise.

All workshop participants will receive an Invasive Plant Patroller’s Handbook, Maine’s Field Guide to Invasive Aquatic Plants, and the NHDES Weed Watcher kit.

The workshop is presented in four parts:

• Overview of invasive species issues in Maine, New Hampshire and beyond (native versus invasive is included in this section).

• Aquatic plants: plant communities; identification fundamentals; ID characteristics of New Hampshire and Maine’s most unwanted and their native look-alikes.

• Plant identification hands-on exercise with live plants (natives and invasives).

• Conducting a screening survey: tools, techniques, documentation, certification, and how these programs differ by state.

Schier said lakefront property owners and frequent visitors on the lakes could benefit from the workshop, which is geared to the layperson. Schier said this workshop is the first time officials from both Maine and New Hampshire will present in the same workshop.

She said so far, representatives from 15 lake associations have signed up. The workshop will be held at 35 H Road in Acton.
