Help us improve the trails and habitats at Haas Sanctuary. We'll be cutting invasive vines and moving debris off the trails and out of key habitats. Bring clippers, wear work gloves (we have extras to loan), dress for the weather. Youth age 10 and up are welcome with one accompanying adult per youth. Call 914-666-6503 or email to register. Check our Google calendar before coming in case of inclement weather. Carpool if possible. Meet at the Sheather Road entrance for Haas Sanctuary.
