Identifying Trees By Bark

When it comes to identifying trees, we often look to the leaves. But what should we do when the leaves have fallen?  

Bark is a feature of trees that persists throughout the year, so learning how to read the patterns of bark is a useful skill for getting to know trees in all seasons. Beyond enriching your identification toolkit, paying close attention to bark also enhances your observation skills while deepening your connection with nature. The minutiae of ridges, furrows, and wildlife sign beckon us to slow down, tune in, and see trees not just as fixtures on the landscape, but as individuals with their own stories.

This program will begin with an overview of the science of tree bark, followed by a hike through the Horn Farm's woodlands to explore field identification of various tree species via bark. Other wintertime identification features, like twig arrangement, buds, and leaf scars, will also be addressed as example trees allow. 

Be prepared for a fully-outdoor class with lots of walking on hilly woodland terrain.

About the Instructor: Andrew Leahy

Growing up in a rural town called Sweet Valley, just south of Ricketts Glen, Andrew spent his life fostering a love for the PA wilds. He attended Muhlenberg College in Allentown and majored in English Literature and Music Composition while exploring regional ecology, slow food, composting, gardening, and foraging in the spaces between. This eventually led him to the staff of the Horn Farm Center, where, as Community Engagement Coordinator, he organizes educational opportunities, coordinates volunteers, runs social media, blogs, and assists with development and outreach projects. 

Andrew is an avid forager and student of wild spaces, interested in rekindling ways of living on the landscape that are place-sourced and mutually nuturing. In 2023, he had the privilege of enriching his experience by taking the Horn Farm Center's Land Steward Training Program. Beyond the Horn Farm, Andrew leads a book club for the Lancaster Composting Co-Ops, volunteers as a land steward with the Lancaster Conservancy, and spends Saturdays selling produce at Green Circle Organics in Lancaster Central Market.
