One of the most common invasive plants in this area is Phragmites australis, also called common reed, which often is found in brackish tidal marshes and disturbed upland sites. While the native species of Phragmites is not invasive, the strain "imported" from Europe quickly can form dense monocultures that out compete and replace native plants.
The Old Saybrook Land Trust (OSLT) and the Conservation Commission have been working with state and federal agencies in an effort to eradicate Phragmites on land trust and municipal property. OSLT also has worked with private property owners to help them acquire funding for Phragmites eradication work on their properties.
Check out the YouTube video below to see staff from the Connecticut Department of Energy and Environmental Protection working in the Fort Saybrook tidal marsh with equipment designed for spraying Phragmites australis.
In the following video, you can see the same piece of equiment outfitted with a cutter to mow Phragmites. The purpose of mowing is twofold: 1) to weaken and kill the Phragmites and 2) to allow sunlight to reach the marsh so seeds of native plants can germinate, grow and repopulate the area.
