Tannersville Cranberry Bog Preserve

Pennsylvania

Known locally as “The Cranberry,” this geological remnant of a long-ago ice age was one of TNC’s first preserves in Pennsylvania.

Overview

Description

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.

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.

While the ice and lake have long receded, the unique ecosystem that remains today 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.

The Tannersville Cranberry Bog Preserve is one of TNC's first nature preserves in Pennsylvania. The preserve in managed in partnership with the Kettle Creek Environmental Education Center who provide educational opportunities for the local community.

Over the years, careful stewardship by TNC and partners including Kettle Creek Environmental Education Center, Pocono Township, the Pennsylvania Department of Conservation and Natural Resources and a local volunteer stewardship committee 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.

Tannersville Cranberry Bog Restoration

Before and After Growth of shrubby vegetation and forest succession leaves the Tannersville bog ecosystem smaller each year. By removing vegetation, TNC aims to restore the diversity and vitality of the leatherleaf-cranberry bog community and keep this ecosystem thriving.

Conservation Community

Restoring the diversity and vitality of Tannersville’s leatherleaf-cranberry bog community is necessary to keep this ecosystem thriving. Although the infilling and growth of shrubby vegetation and forest succession is a natural process, it may be happening more rapidly due to nutrient input from nearby roads and from residential development in the watershed.

In 2012, Dr. Ray Milewski and students from East Stroudsburg University established several small study plots at the preserve. Their research suggests that removing woody, shade producing vegetation allows rare bog plants to reestablish themselves.

In an effort to engage our conservation community and encourage the return of certain species not seen at Tannersville in decades (like the grass pink orchid Calopogon tuberosus), PA/DE staff, trustees and volunteers came together in late March and early April 2022 for a series of grueling but rewarding workdays.

Weather was the biggest wild card—the temperature at the first day’s morning meeting location was a bracing 20 degrees. Regular changes in weather occured during the two weeks, with rain, snow and sleet showers experienced during the first week.

The work involved removing trees with chainsaws, lopping smaller brush and limbs and dragging the cut material to the boardwalk and out of the bog to a chipping area. The resulting mulch will be used on upland trails.

TNC staff and volunteers were able to complete six of the planned ten days of restoration work, giving us a great start to our ongoing plan for opening up areas of the bog. The total area where vegetation has been removed to date comes to approximately 0.37 acres—about 0.25 acres were cleared this year. The target restoration area inside the boardwalk loop is approximately 1.3 acres. 

Our restoration efforts are focused along and around the bog boardwalk to allow us to continue building on past restoration success and provide the greatest opportunity to showcase that success to preserve visitors. There is still much work to be done and we’ll be reviewing and assessing those changes through our partnership with Monroe County Conservation District – Kettle Creek Environmental staff through their public walks in the bog scheduled throughout the year.

Visitor Information

  • Because of its fragile nature, the bog itself can be visited only during regularly scheduled walks conducted by the Monroe County Conservation District's Kettle Creek Environmental Education Center. Private walks are available for groups upon request; dogs are not allowed on the boardwalk trail.

    Public access is always permitted on the North Wood and the Fern Ridge trails. 

    PLEASE NOTE: when traveling to the preserve, please do not turn into the home at 107 Lavender Lane (at the corner of Lavender Lane and Cherry Lane Road). This is a private residence; please respect our neighbor's privacy.

  • North Wood Trail

    This flat loop trail system passes along the edge of the wetland and through a mature hardwood forest dominated by oak trees.

    The shorter loop along the edge of the ridge offers a better view of the area and the longer loop passes through several areas of ever- green trees and through excellent wildlife habitat. In winter, these trails are good for cross-country skiing.

    Fern Ridge Trail

    This single loop trail rises slowly in the beginning through an oak hardwood forest. Then it follows an old road and eventually proceeds down a slight hill to run along the very edge of the bog with lots of wetland trees, shrubs and ferns including blueberry bushes, yellow birch and red maple trees.

    The Boardwalk Trail remains accessible by guided tour only; dogs are not allowed on the boardwalk trail. Learn more about regularly scheduled hikes by contacting the Kettle Creek Environmental Education Center at 570-629-3061.

  • Plants: visitors will find plants such as calla lilies, gold thread and carnivorous sundew and pitcher plants, as well as native orchids such as rose pogonia and the state endangered heart-leaved twayblade. Other endangered plants include bog rosemary and Labrador tea. Shrubs such as leather leaf, sheep laurel and swamp azalea can also be found here.

    Animals: black bear, river otter, bobcat, beaver, porcupines, mink, wild turkey and snowshoe hare can be found here. Canada warbler, wood thrush, scarlet tanager, golden-winged warbler, eastern towhee and whip-poor-will have also been spoted at the preserve.

  • 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 the 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.

  • Please follow all rules and guidelines of the Monroe County Conservation District/Kettle Creek Environmental Education Center.
