Standing out in vivid contrast to the surrounding Pocono Mountains landscape, Tannersville Cranberry Bog provides a snapshot of colder times. Thousands of years ago, a large glacial lake occupied the space of what has since become a thick soup of peat moss.
Today, while the ice and lake have long receded, the unique ecosystem that remains serves as the southernmost low elevation boreal bog along the eastern seaboard. It represents an intricate transformation that took place over the millennia and would be impossible to replace if destroyed.
Affectionately known locally as “The Cranberry,” Tannersville Cranberry Bog is ingrained in the local community and culture, inspiring wonder among students, educators, scientists, nature lovers and photographers who visit each year. Of special interest are some of North America’s most beautiful native orchids, including rose pogonia and the state-endangered heart-leaved twayblade.
The Tannersville Cranberry Bog Preserve is one of The Nature Conservancy's first nature preserves in Pennsylvania. Over the years, careful stewardship by TNC, partners and the local community has yielded great returns as the bog soaks up rain and runoff like a giant sponge--cleansing water and controlling pollution throughout the Pocono Creek watershed.
