The 77.5-acre Pool Wildlife Sanctuary, located along the banks of the Little Lehigh Creek in Emmaus, Pa., was entrusted to Wildlands Conservancy in 1975 by the late Leonard Parker Pool, founder of Air Products and Chemicals, Inc.

The Sanctuary features the Harry C. Trexler Environmental Educational Center, which houses the Lehigh River Watershed Exhibit.  The Lehigh River Watershed Exhibit is a part of the Conservancy's environmental education outreach.  School children from across the Lehigh Valley visit the Lehigh River Watershed Exhibit to learn about the wildlife in the Lehigh River Watershed.  The Exhibit features a series of interactive displays presenting basic watershed concepts, a diorama of Pennsylvania mammals and birds, a live amphibian and reptile terrarium, a fresh-water stream aquarium, and a unique window seat that overlooks the ponds.   

The Pool Wildlife Sanctuary is also the home of the Environmental Enrichment Center, which houses the Conservancy's Education Department offices and classrooms.  The remainder of Wildlands Conservancy's offices can be found in the white farmhouse.

The grounds also feature a pavilion, a bird blind, an arboretum, ponds, nature trails, a collection of native Pennsylvania trees, deep woods and wildflower meadow. Open year-round to the public, seven days per week from dawn to dusk, the Sanctuary is known for its excellent nature education calendar and activities for children and adults.
