Join us to help measure and inventory the tall trees of Ferncliff.  No previous ability required. The program will begin with a tree measuring tutorial. If you have measured with us before feel free to show up at 10. We will be hiking off trail, so wear sturdy shoes and tick repellant. Space is limited for this program, so preregistration is required. For more information and to Pre-register, email aludwig@pa.gov or call 724-329-0986.
