MORE INFORMATION
The threat: Two types of water milfoil could threaten Maine's lakes and ponds: variable water milfoil and Eurasian milfoil. Variable water milfoil is less damaging than Eurasian milfoil because it grows close to the shoreline. It has been found in Sebago, Thompson and Auburn lakes and Cushman Pond. Eurasian water milfoil can overwhelm native vegetation, ruin water quality, destroy fisheries and affect recreational activities. It grows in water up to 20 feet deep. Its tendrils rise up to the surface of the lake or pond and form mats that choke native plants.

Reproduction: All milfoils have feather-like leaves arranged in whorls around the stem. Milfoil is spread mainly by boats and trailers hauled from water with infestations and then put into other lakes or ponds. It reproduces primarily through fragmentation. A lake or pond can be infested from a single fragment of milfoil.

The penalty: In 2001, the Legislature passed a tough invasive aquatic plant law that established an inspection system to check boats for plant fragments and created a rapid response protocol for lakes when invasive plants are discovered. The law made it illegal to transport any aquatic plant on the outside of a vehicle, or to sell, propogate, or introduce to Maine waters any of the eleven invasive aquatic plants. Violations may result in fines up to $500.

Eradication: States already infested with Eurasian water milfoil have had little success eradicating the invasive plant. Methods tried have included herbicides and mowing the plants.

Milfoil is an invasive plant that the state would like to keep out of Maine's inland waters. Beginning in 2002, all motorized watercraft on inland waters must display a Lake and River Protection Sticker (tidal waters are not included). The green triangular stickers cost $10 for residents and $20 for nonresidents. You can purchase them at online at the IF&W online store.

For more on milfoil, see the Fish and Wildlife's Milfoil Web page or the Dept. of Environmental Protection Web pages.
