Lehigh Gap Nature Center

On the Kittatinny Ridge, by the Lehigh River, D&L and Appalachian Trails…LGNC is the only Superfund site in the country to be restored to an environmental education center.

The Lehigh Gap Nature Center is a member-supported 501(c)3 non-profit conservation organization located in Lehigh Gap, PA, at the foot of the Kittatinny Ridge. Our mission is to protect the wildlife and enhance the habitats of our Refuge and the neighboring Kittatinny Ridge. We promote conservation in the Lehigh River Watershed through education, research, and outdoor recreation for the benefit of present and future generations. The nature center includes the Osprey House, our “green” building used for indoor instruction and gatherings, and a 756-acre wildlife refuge. The refuge features approximately 400 acres of restored Superfund site in addition to other unaffected habitats, including ponds, bottomland wetlands, a 2.5 mile riparian zone, forested slopes, cliffs, and savanna at the higher elevations.

Our Mission
The mission of Lehigh Gap Nature Center is to protect the wildlife and enhance the habitats of our Refuge and the neighboring Kittatinny Ridge. We promote conservation in the Lehigh River Watershed through education, research, and outdoor recreation for the benefit of present and future generations.

The vision of Lehigh Gap Nature Center is a vision of hope. In the process of healing the land, we built a community engaged in conservation, education and research. In telling this story, we seek to inspire others to do what some judge as impossible for our planet – to restore natural functions and beauty where they have been damaged and to protect those places that remain ecologically healthy. We seek to connect a diverse array of people to nature and place, and in doing so, build support for conservation in succeeding generations. Hope is contagious!

History of LGNC
Lehigh Gap Nature Center Osprey House 2002  oct-2002sm  2006-august

Lehigh Gap Nature Center (LGNC) was born out of the efforts of a small group of naturalists who recognized the value and potential of the area. Perhaps the organization’s earliest origins can be traced to the late Grant White, who was quoted in a 1960s-era newspaper article as saying there ought to be a nature center in the Lehigh Gap. Don Heintzleman, through his hawkwatching efforts at Bake Oven Knob (which also dates back to the ’60s), built a community concerned about wildlife and founded the Wildlife Information Center (WIC).

The WIC is the official 501(c)3 nonprofit incorporation under which LGNC still does business today. In the mid-’90s, the WIC had an office in downtown Slatington, but sought a property upon which they could build an environmental education center. An old farm house in the Lehigh Gap was a wonderful prospect, given its proximity to the Lehigh River and Kittatinny Ridge and with a pond on site. Dan Kunkle (who at that time was a board member) recalls that upon visiting the site to inquire if the property might some day be for sale, the owners acted as if the WIC’s arrival was divine providence; the people had just listed their home for sale on the internet. While touring the grounds, the group sighted an osprey overhead, which served as the inspiration for the name the house bears today – the Osprey House.

The Osprey House is the headquarters for the Lehigh Gap Nature Center and provides crucial indoor facilities to support conservation, research and education activities on our adjacent 756-acre property, the Lehigh Gap Wildlife Refuge. Once the Osprey House was acquired, the Refuge was purchased in two parcels (we later acquired the arboretum site). Early on, LGNC established a tradition of working through partnerships by partnering with organizations like the Delaware & Lehigh National Heritage Corridor and DCNR, whose guidance and funding made the purchase of our property possible. Approximately 400 acres of our property falls within the Palmerton Zinc Pile Superfund Site and was heavily contaminated with toxic metals, (lead, cadmium and zinc) between 1898-1980, during the period of operation of the New Jersey Zinc Company in Palmerton, PA.

We followed the advice of plant scientist John Dickerson and former D&L Trail Manager Bill Mineo and planted warm season native grasses to remediate the site and thereby stabilize the metals in the soil and also prevent them from re-entering the food chain at rates which would harm wildlife. We re-vegetated the barren parts of our land, created a trail system, and developed an environmental education and research program that continues today. Our restoration is ongoing as we practice adaptive management, including prescribed fires in our repertoire of conservation tools as we strive to exclude invasives and keep the metals from re-entering the ecosystem and food chain at toxic levels. To quote the Hommer Foundation’s Peter Kern, LGNC is truly an environmental miracle and an educational jewel.
