Conservation at LGNC

How we restored life to a contaminated, barren moonscape.


The Lehigh Gap Nature Center promotes conservation in its research and activities, in order to conserve and restore habitats in the refuge.

The Greening of the Mountain

As a result of decades of air pollution resulting from 20th century industrial zinc smelting in Palmerton through the 1970’s, much of the mountain at the Lehigh Gap Refuge and in surrounding areas was deforested, eroded, and left with high levels of zinc and other heavy metals.  Along with our partner, Viacom, much of this land is being restored using various species of native, zinc-tolerant, warm-season (prairie) grasses.  Beginning in 2003, test plot areas on the mountain were seeded and fertilized, both from the ground and later by aerial application of seeds with crop dusters.   The success of this program has been remarkable, as can be seen from the dramatic transformation of the mountain, evident in the photographs below.  As the grasslands thrive and expand, we anticipate a growth in the abundance and diversity of wildlife supported by the renewed habitat.




To learn more about this effort, read the following articles from Wildlife Activist by LGNC Executive Director Dan Kunkle, which describe what has been done to restore vegetation to the mountain at the Lehigh Gap.
