Sudbury-Assabet-Concord River Watershed

About Us

The SuAsCo CISMA (Cooperative Invasive Species Management Area) is a partnership of organizations that intend to manage and control invasive species in the Sudbury, Assabet, and Concord (SuAsCo) watershed. The partners in this CISMA wish to share information, educate, and plan strategies for dealing with invasive species. This CISMA will protect the biological, aesthetic, cultural, historical, and recreational values of natural areas, farmland, water resources, and scenic vistas by cooperating, coordinating activities, and sharing resources necessary for the prevention and control of invasive species on public and private lands across ownership boundaries within the CISMA.

Invasives

Invasive species pose one of the greatest threats to the biodiversity, natural landscapes, agricultural interests, recreational activities, quality of life and scenic beauty of the watershed. There are many ways to deal with this threat including initial prevention, early detection, and control through manual removal, mechanical treatment, pesticide application, biological control, grazing and fire. Invasive species do not stop at ownership boundaries, and without a coordinated effort among a broad range of private and public land owners and land managers, these species will continue to invade our watershed, altering the habitat, reducing the biodiversity, and reducing the recreational and aesthetic value of the watershed. The intention of the SuAsCo CISMA is to guide management efforts within the watershed and determine priorities for management.

Geographic Scope

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.

To be expected, the boundaries of the SuAsCo watershed do not match up with the boundaries of the towns within the watershed. Listed below are the towns that are fully or partially within the watershed. The towns whose land is less than fifty percent within the watershed are noted by their gray text coloration.
