Buckthorn is a non-native shrubby tree that can quickly takeover a natural community. Help is needed to battle this invasive species in the Haskell Noyes State Natural Area within the Kettle Moraine State Forest - Northern Unit. We will meet at the small parking lot off County Road GGG just south of County Road SS near New Prospect. Wear long pants, long-sleeved shirt, gloves and hat. To protect against biting bugs, tuck your pants into your socks and bring insect repellant. Remember to bring drinking water and long-handled pruning shears if you have some.
