New Regulations Crack Down On The Spread Of Invasive Plants

COVENTRY, RI — The Rhode Island Department of Environmental Magangement is taking steps to prevent the spread of invasive plant species in the state's freshwater bodies. Under new regulations, the transport of any plant or part of a plant on a trailer, motor, fishing supplies, boat, or gear is prohibited, with a $100 penalty for each violation.

Katie DeGoosh-DiMarzio, an environmental analyst with the DEM's Office of Water Resources said invasive species can be spread by a single plant fragment.

"Many of the aquatic invasive plants in Rhode Island ... do not need entire root systems to successfully establish in a new spot," she said. "Cleaning off every bit of plant from recreational gear used at one pond is essential before visiting another — this includes boats, kayaks, canoes, motors, trailers, paddles, jet skis, fishing gear, waders, water tubes, and anchors. These efforts help combat the spread of aquatic invasive species in Rhode Island waterbodies."

In Rhode Island, more than 100 ponds and lakes have at least one invasive plant, and they have been recorded in 27 segments of river in the state. Two species, variable milfoil and fanwort, are considered widespread in the state, the DEM has identified 14 different aquatic invasive plant species. A 2013 study showed than nearly 40 percent of boats at freshwater ramps had some type of aquatic plant attached to it.

"It's crucial that boaters prevent moving these plants on boats and trailers to avoid spreading them to new locations where they may become problematic," the department wrote in a release.

Boaters are reminded to always check their boat, trailer, motor, lines and other gear to plants and remove them before leaving. Removed plant fragments should not be put back into the water, instead thrown away in a trash or compost bin. The department also asks residents to check its website to see if invasive plants have been documented at a waterbody before visiting.

The department issued the following reminders to boaters:

• CLEAN: Remove all visible aquatic plants, animals, and mud from all equipment before leaving water access.
• DRAIN motor, bilge, livewell, and other water-containing devices before leaving water access.
• DRY everything for at least 24 hours OR wipe with a towel before reuse.
• DISPOSE of unwanted bait, worms, and fish parts in the trash.
