Invasive Species are species that are not native to an area and significantly alter the ecosystems they populate. Invasive species frequently aggressively colonize their new habitat, oftentimes outcompeting, displacing, or killing native species. Many invasive species are introduced to their new habitats accidentally.

In the Mystic River Watershed a short list of the many invasive plants include:

Invasive species pose a threat to the Mystic River Watershed by altering the ecology of the infested area. For example, these invaders can reduce the amount of light, water, nutrients and space available to native species, effecting water quality and the capacity of native species to survive. Additionally, invasive species can alter hydrological patterns, soil chemistry, moisture-holding capacity, and erodibility. 


Volunteers clear water chestnut from the MysticHOW CAN YOU HELP?

  • Volunteer! Volunteers are most needed in May, June and July as  plants can be removed before seeds begin to grow. Additional hand-pulling can be effective through August for some species.
  • Pull up existing invasive plants in your yard or neighborhood.
  • Boaters are encouraged exercise caution in not spreading the seeds: much of their spread can be eliminated by inspecting boats, trailers, and fishing gear that may inadvertently carry the seeds far and wide.
  • Donate. Your donation will help MyRWA organize and implement invasive removal.
