Free Aquatic Plant Identification Workshop

Thursday, July 16, 2015, beginning at 6:00 p.m., at the Petapawag boat launch off Nod Road in Groton

Do you have a favorite paddling or swimming spot where you've found an aquatic plant and wondered if it's native or invasive? Are you part of a pond committee or river group looking to protect the health of your waterway from invasive plant species? This 2-hour class will be led by Tom Flannery, Aquatic Ecologist with the Massachusetts Department of Conservation and Recreation's Lakes and Ponds Program. The workshop begins with an introduction to the invasive non-native species issue, how exotic species are introduced into our waterways, methods of dispersal, basic terminology, and guidance on performing bi-weekly monitoring and completing plant surveys. The remaining 3/4 of the class will engage participants in hands-on identification. A variety of non-native and native plant species are provided, and people are encouraged to bring in their own samples. Participants will become familiar with using a dichotomous key and, although the emphasis is on exotic species, the goal is to teach people how to use the key so that they will be able to identify the majority of common aquatic plants in their lake or pond (native or otherwise).

This workshop is free and open to the public, made possible by a grant from the Greater Lowell Community Foundation. Attendees may park at the NRWA River Resource Center at 592 Main Street (Rt. 119) in Groton, and walk to the nearby boat launch. The workshop is limited to 20 people; pre-registration is required. To pre-register, please contact Martha Morgan, NRWA Water Programs Director, at (978) 448-0299, or This email address is being protected from spambots. You need JavaScript enabled to view it.

Native Caterpillars of New England: Live Caterpillar Show and Moth-Lighting Hour

Tuesday, July 14, 2015, from 6:30 to 9:00 p.m.
NRWA River Resource Center, 592 Main Street (Rt. 119) in Groton

Join Sam Jaffe and The Caterpillar Lab as they bring a full evening of caterpillar glory to the Nashua River Watershed Association in Groton. Explore the wonder of New England's native caterpillars with live caterpillars and interactive exhibits followed by a unique moth-lighting hour. Caterpillar expert Sam Jaffe and his team of caterpillar gurus will be on hand to answer all of your questions during this up close look at the amazing world of caterpillars. Stop in at any time during this 2½ hour open house style presentation. Appropriate for all ages. During the open house, Sam will also lead short caterpillar-finding excursions on the property.

The Caterpillar Lab will also conduct an outdoor moth-lighting from 9:00 to 10:00 p.m.. Sam will use powerful lights and a white back-drop to attract moths and other flying insects of every shape and size! This is a dynamic opportunity to see what moth species are out and about, with no harm to the insects. Feel free to bring your camera or cell phone to take pictures. This is the first public moth-lighting that The Caterpillar Lab has conducted.

Naturalist photographer Samuel Jaffe grew up in Eastern Massachusetts chasing birds, mucking through ponds, and turning over leaves. Over the last five years he has developed a project to raise and photograph all of the more charismatic native caterpillars. The project has blossomed and expanded into caterpillar exhibits, shows, walks, and talks, culminating in the creation of The Caterpillar Lab in 2013. Sam is currently working towards a Masters in Environmental Education at Antioch University of New England. Sam's photography has been exhibited at the MIT Center for Theoretical Physics in Cambridge MA, and in the hallways of Antioch University New England in Keene NH. Learn more about Sam and The Caterpillar Lab.

This presentation is free and open to the public, made possible in part by a grant from the Groton Trust Funds' Lecture Fund. In the case of heavy rain, the moth-lighting hour will be cancelled. Pre-registration is requested for planning purposes. When you pre-register, please indicate if you are coming to the exhibit open house only, or if you plan to also attend the moth-lighting hour.
