Trexler Nature Preserve in Lehigh County, Pennsylvania, began as industrialist General Harry Clay Trexler’s private game reservation on land he assembled between 1901 and 1911 from farms along Jordan Creek and Mill Creek. Seeking both sport and conservation, he enclosed about 1,000 acres and stocked them with deer, elk, and buffalo, hoping to protect big game, especially bison. The land had been settled and farmed since at least the 1760s, with early mills on Mill Creek. After Trexler’s death, the county acquired the property for public use, and a 2006 settlement transformed it into a fully accessible preserve focused on recreation, ecological restoration, and protection of its distinctive creek-and-ridge landscape.
