Phragmites is a perennial and aggressive wetland grass that grows over 10 feet tall and is easily recognized by its height and fluffy seed heads. They are especially noticeable along the Route 1 corridor within the marsh, especially on the upland side of the roadway. Phragmites have very little value to the diverse populations of wildlife in the marsh. Their thick growth and rapid spread choke out valuable plants and reduce the biodiversity of the marsh's delicate and highly- valued ecosystem. This type of Phragmites is not native to this area, and it has significantly compromised wetlands up and down the east coast. The weeds aggressively spread and colonize new areas every year and are very difficult to eradicate.
Work will begin in August on Phragmites control, which will involve a variety of actions utilizing highly specialized equipment, licensed and trained contractors and application of a specially formulated herbicide that affects only plants. All work will take place under the watchful eyes of the partners and other natural resource management agencies. Officials are hoping to achieve a 95% or greater elimination rate in the target areas.
