Pennypack Ecological Restoration Trust

Event Details October 20th – Beech Leaf Disease Walking Tour, Tuesday, 4:30 PM to 5:30 PM In summer 2024, beech leaf disease (BLD) was discovered in American beech trees along the northern edge of the Pennypack Preserve. In 2025, Pennypack Trust began hosting a research team from Bartlett Tree Research Laboratories to study different methods—including silvicultural thinning and chemical injections—for slowing the progression of BLD and preserving one of our most heavily American beech-dominated forest tracts. Now that the experimental treatments have been completed, researchers will monitor their effects on the trees over the next five years. Join Dr. Matthew

Join Executive Director Chris Mendel for a tour of the Margaret V. MacPhee Wildlife Sanctuary where PERT has begun work on a long-term management plan to restore native diversity and improve wildlife habitat quality.  This property will remain private and closed to daily public access as Ms. MacPhee intended. As ever, Chris will merge habitat objectives with the land’s varied legacy uses to inform our management plan. For Pennypack Trust members only. Limited to 18 participants. $5 per person.
