Water Chestnuts in the Nashua River Lecture/Slideshow

Thursday, October 23, 2014 beginning at 7:00 p.m.
NRWA River Resource Center, 592 Main Street (Rt. 119) in Groton, MA

Water chestnuts are an invasive aquatic plant first found in the Pepperell Pond impoundment area of the Nashua River in the late 1990s. These plants create an impenetrable mat of growth that makes the river inaccessible to boating and fishing. Their growth replaces ecologically critical native plant species. When the dense mats die off in the fall, they sink and decay, which depletes oxygen levels vital to fish, destroying native fish habitat with resulting negative impact on fish populations. The Nashua River Watershed Association (NRWA) has been working for over a decade to contain this aggressive infestation. The NRWA invites the public to learn more
about "Water Chestnuts in the Nashua River" during this free presentation. Martha Morgan, NRWA Water Programs Director, and Kathryn Nelson, NRWA Water Monitoring Coordinator, will present an informative slideshow on the plant's life cycle, impact on wildlife, and efforts to eradicate it in the Nashua River. This is an opportunity to become better informed about this plant and share information on how to prevent its spread and reduce its impact at existing infestation areas, either in the river or in our local ponds.
This program is free and open to the public. Pre-registration is appreciated for planning purposes.
