GROTON -- The Nashua River Watershed Association invites individuals and families with children ages 10 and up to join us for "Predator or Prey?" on Saturday, Feb. 8, from 10 a.m. to noon, at one of Groton's most environmentally diverse conservation properties.

This tracking workshop is designed to look closely at the trail patterns, prints and behaviors of our local predators and prey animals as they negotiate the forests, fields, and wetlands during harsh winter months.

Winter survival challenges all wildlife and their stories can be told through the tracks and signs left behind. The activity will include hiking at a moderate pace, with some off trail exploration.

Please dress with multiple layers, winter boots, water resistant outer gear (snow pants or gators); pack a water bottle & energy snack. Snow shoes are helpful, but not necessary.

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 pre-registration is required.

Detailed directions to the meeting location will be provided upon registration.

To pre-register, please 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.
