The Althouse Arboretum is the result of a unique agreement between Upper Pottsgrove Township and GreenAllies designed to create a regional destination for environmental education and service. While most of the property is owned by the township, GreenAllies manages and runs the property and all activities at no cost to the Township. All activities, trail work and more are done by GreenAllies with input from local students and community members.

The 17 acre property has been converted into an outdoor learning area with trails and outdoor education features. It now connects to two other large open space lands increasing program options while preserving additional acreage.

house info signThe house on the property was donated to GreenAllies. When reconstruction is completed the upstairs will become the office for GreenAllies. The downstairs will become a place for those who use the Arboretum to gather and a community resource center. Plans are being made to add a classroom building. Careful planning and modern design features will make this location a place for all members of our community as well as visitors from other areas to visit, learn and enjoy.
