They are stealthy. They don’t respect property lines. And they spread surprisingly quickly for something rooted in the ground. When aggressive, invasive plants threaten the health of our local rivers, fields, and woodlands. That’s the time for neighbors to band together. 

That is why The Trustees have helped to form a watershed-wide partnership comprised of our own neighbors -- concerned volunteers, land trusts and government agencies -- to fight the spread of invasive species in the Westfield river watershed.

Called the Westfield Invasive Species Partnership (WISP), the idea was born from the concern of Trustees’ Regional Ecologist Julie Richburg, who saw that the watershed was beginning to experience rapidly spreading populations of invasive plants such as Japanese knotweed and garlic mustard. The plants were firmly established in certain areas, but had not yet reached others. The time to act to keep these species and other new ones on the way from spreading was now, and it required a larger focus area than the property of any single landowner or organization.

The partnership now includes representatives from The Nature Conservancy, Mass Audubon, the New England Wildflower Society, the Westfield River Wild and Scenic Advisory Committee, Westfield Environmental Center at Westfield State College, the Hilltown Land Trust, and the MA Dept. of Conservation and Recreation’s Service Forestry and Forest Stewardship programs. The goal of the partnership is to work with residents and landowners in the watershed by providing and collecting information on invasive species, and to join together to eradicate existing infestations of invasive plants and prevent new ones.

WISP builds on the momentum that The Trustees’ Highland Communities Initiative created last year with its ‘Least Wanted’ informational campaign about several species of top concern. With some funding from the federal stimulus program, The Nature Conservancy is providing staff time to help get the new effort up and running. One of the first steps for the partnership is to survey areas in the watershed that are both heavily infested with invasives and those that are relatively free from the aggressive invaders. Volunteers are needed to share their knowledge of such areas in their towns, as well as to head out in the field to collect new data.
