Long Pond Preserve and Hauser Nature Center

Long Pond Preserve harbors species tolerant of cooler temperatures reminiscent of the region’s glacial past.



In contrast to typical barrens usually associated with dry, shallow, nutrient-poor sandy soils, the mesic till barrens found at the Long Pond Preserve thrive in rich loam full of moisture and capable of supporting a unique type of woodland landscape more characteristic of Canada’s northern climate. That is because, historically, regular and somewhat frequent wildfires sustained this unique habitat and prevented it from succeeding to mature forest.

However, for more than a half-century, suppression of wildfires in this rapidly developing landscape has jeopardized the health of Long Pond’s mesic till barrens. Without this natural disturbance, more than 70% of the original habitat has transformed into fire-intolerant forest that does not support the rare species known to reside here.

In response, TNC, together with partners, has employed cutting-edge science to assemble a detailed inventory, maps of plant and animal communities, and spatial and demographic data for the area encompassing the Long Pond Preserve. This data is crucial to effectively managing these unique barrens today and in the future.

Over the years, TNC has worked with partners to acquire property, complete an ecological management plan and establish a prescribed fire program for this unique landscape. This has led to cutting-edge conservation strategies that included the enrollment of 8,588 acres by Bethlehem Water Authority into the Working Woodlands Program, which provides forest landowners with a rigorous analysis of their property and access to forest certification and carbon markets, in exchange for a commitment to practice sustainable forestry.

TNC also entered into an agreement with the Pennsylvania Game Commission to employ prescribed burning to restore more than 2,000 acres in the barrens over the past decade. Today, TNC continues to work with local government and other partners to acquire and manage additional lands, and provide public access to quality outdoor recreation.

  • What to See: Plants and Animals

    Long Pond is one of Audubon Society’s Important Bird Areas of Pennsylvania. The landscape hosts rare butterflies and moths, as well as birds that are declining throughout most of Pennsylvania such as osprey, northern harrier, eastern towhee, prairie warbler, whip-poor-will, common yellowthroat and chestnut-sided warbler.

    The area also hosts American bittern and northern harrier—bird species not commonly observed in other parts of the region. Visitors are encouraged to enjoy prime bird watching from the early spring through fall.

    This preserve's exceptionally diverse mesic till barrens—comprised of swamps, bogs, marshes and shallow ponds surrounded by woodlands with a heath understory of Rhodora, sheep-laurel, highbush blueberry and huckleberry bushes—attracts many species of boreal plants, insects, birds and mammals, and features rocks with glacial signatures more typical of Canada and New England.

  • Community Science: iNaturalist

    We are creating a community science database of all kinds of life—from lichens to ants, mushrooms to plants, birds to mammals and everything in between for our preserves in Pennsylvania and Delaware.

    TNC's roots began with local citizens and scientists concerned about special places and species. That legacy continues today. Across our lands, we are utilizing iNaturalist—a digital platform that gives users an opportunity to share and discuss their findings.

    Of our 14 preserve projects in iNaturalist, nine have observations recorded; help us increase that number and our understanding of the species—good and bad, native as well as invasive—that can be found on TNC lands across the state. This information can also help guide and inform our conservation staff's management and monitoring decisions.
