Sudbury-Assabet-Concord River Watershed
Working together to restore the native habitats of the Sudbury-Assabet-Concord River Watershed

The SuAsCo CISMA (Cooperative Invasive Species Management Area) is a partnership of organizations that intend to manage and control invasive species defined by the geography of the Sudbury, Assabet, and Concord (SuAsCo) watershed. Thirty-six towns are part of the SuAsCo Watershed, and we are all connected by the Sudbury, Assabet, and Concord river system. The watershed covers approximately 377 square miles and includes a variety of upland habitats, wetland habitats, historic sites, scenic sites and recreational areas. The towns, state and federal government agencies, and environmental organizations that hold land in the watershed all share an interest in the work of the CISMA.

What are invasive species

Any plant or animal that is not native to an area.

Able to reproduce without any natural checks on population growth and out-compete native organisms.

These species begin to fill the ecological roles of native species and in short order can entirely replace native species.
