December Exhibit of the Month

Fabulous Fall: The Changing Leaves and Migrating Wildlife of Assabet River NWR

Stop by the Visitor Center during regular hours and see our new monthly exhibit. Leaves changing color and falling, wildlife stocking up on food for the winter, and migrating waterfowl headed for warmer climates. The fall season on the Refuge is a beautiful time, as the landscape undergoes a dramatic transformation. This change alters the behavior of animals found on the refuge, as well as which species can be observed. This month’s exhibit will explore concepts like migration and hibernation.

December Movie of the Month

America's Wildest Places

Can’t get enough of National Wildlife Refuges? Good thing America has 566 of them! This film takes viewers on an audio/visual tour of eight very different National Wildlife Refuges in eight separate states. From gators to grizzlies, this film has something for everyone. (Runtime: 120 minutes).

Saturday, December 9, 9:00 AM - Noon

APT Invasive Plant Removal Work Party

Help keep the refuge clear of invasive plants! Assabet Pulling Together (APT) will be removing invasive plants from Assabet River NWR each Saturday through the fall. There will be no work session on Saturday December 2nd, but the final work party for 2017 will be held on Saturday December 9th, if there is no snow and the ground is not frozen. Suggested attire includes layered clothing, insulated boots, a hat, and work gloves. Sessions are open to drop-ins. Please meet at the Visitor Center.

Please contact Dave Lange for more information.

Friday, December 15, 6:00 PM

Owl Prowl at Great Meadows NWR

Have you ever heard an owl before? After learning about owls inside, we’ll embark on a moderate hike on the trails to listen and look for owls on the Refuge. All ages are welcome, but be prepared for night-time hiking on uneven trails and dress for the weather. Please bring a flashlight or headlamp with you.

This event will take place at the Refuge Headquarters at 73 Weir Hill Rd Sudbury, MA 01776.
