Introduction to tracking

GROTON -- The Nashua River Watershed Association invites families with young children to join us for "Who Goes There?" on Saturday, Feb. 2, from 10 to 11:30 a.m., at the Shepley Hills Conservation Area.

This tracking workshop is designed to introduce young children to animal tracks and clues. Discover the secrets of our local winter wildlife with an adventurous hike through forests and along streams looking for signs of wildlife and imagining what takes place when we are not looking.

The activity will be light to moderate, with some off-trail walking. Dress in multiple layers with winter boots, water-resistant outer gear (snow pants or gators), and pack a water bottle and an energy snack.

The fee is $8 per person or $24 per family for NRWA members; $10 per person or $30 per family for nonmembers. Space is limited and registration is required. Detailed directions to the meeting location will be provided upon registration. To register contact Stacey Chilcoat, NRWA River Classroom director, at 978-448-0299, or email StaceyC@NashuaRiverWatershed.org. The NRWA is a nonprofit environmental organization that depends on memberships for support.

Intermediate tracking workshop

GROTON -- The Nashua River Watershed Association is leading "Fast Tracks, Slow Tracks: Searching for Clues to Winter Wildlife in our Forests, Fields and Streams," an intermediate level tracking workshop, on Sunday, Feb. 3, from 1 to 4 p.m., at the Williams Barn Conservation Property and the Chestnut Hills trail area.

This three hour, in-depth tracking workshop designed for adults and older children ages 12 and up will focus on three distinct winter habitats and the animals that not only survive but thrive during our harshest months. Develop a greater understanding of these hardy inhabitants and learn to "read" their stories through the signs and clues we discover along the way.

The activity level will be moderate hiking or snowshoeing, mostly off-trail. Dress in multiple layers with winter boots, water-resistant outer gear (snow pants or gators), and pack a water bottle and an energy snack.

The fee is $20 per person for NRWA members and $25 per person for nonmembers. Space is limited and registration is required. Detailed directions to the meeting location will be provided upon registration. To register contact Stacey Chilcoat, NRWA River Classroom director, at 978-448-0299 or email StaceyC@NashuaRiverWatershed.org.

The Science of Rivers and Water in Winter

GROTON -- Where do river animals go in winter? Young scientists ages 7 to 11 are invited to join us for this exploration of "Rivers and Water in Winter" during the Nashua River Watershed Association's Science Saturday on Feb. 9, from 1 to 2:30 p.m., at the NRWA River Resource Center, 592 Main St.

We'll do some indoor water experiments and figure out the physics of water. We'll be investigating in both indoor and outdoor settings. The program is led by Mary Marro, NRWA's environmental education director.

Science Saturday costs $25. Registration is required. To register contact Marro at 978-448-0299 or email MaryM@NashuaRiverWatershed.org. The NRWA is a nonprofit environmental organization that depends on memberships for support.
