Knotweed Project

Japanese Knotweed is called the Godzilla weed because it is so hard to defeat. This non-native bamboo is creeping its way around Loon Lake’s waterfront, destroying the precious natural habitat. Loon Lake Watershed Improvement Alliance (LLWIA) and Finger Lakes Partnership for Regional Invasive Species Management (PRISM) have joined in a pilot project designed to halt the progress.

Volunteer have removed dry growth and emerging buds on a large pilot patch at Serenity Cove. The area was than covered with metal mesh and any green material carefully destroyed. The shoots will grow through the ½’ holes and be strangled. This prevents nourishment from getting to the rhizome root system ‘starving’ the plant while killing the shoots. The mesh will need to be in place for a few years to eliminate the plant. Volunteers will monitor, taking pictures and observing the results.

In the past two years, LLWIA volunteers treated a knotweed patch on Loon Lake Wetland Preserve by covering it with heavy mil plastic and tarps. This experiment has had some success but there are issues with degeneration of plastic materials. Results from both forms of remediation will be compared You can help by checking your property for this invasive plant and notifying Alice Publow with any discoveries or questions. Donations made to LLWIA at PO Box 372 Wayland NY 14572 will support projects like this one and others that benefit the Loon Lake environment.
