The Tannersville Bog was one of The Nature Conservancy's first preserves. It's 1,000 plus acre preserve containing a 150-acre wetland and a relict boreal bog. The bog was once a huge glacial lake. Since the ice receded 10,000-15,000 years ago, approximately 60 feet of peat has accumulated on the floor of what was once the 715-acre lake. Today, the bog stands out in contrast to the surrounding forests. It is a world of sphagnum peat moss hosting beautiful plants like calla lillies, orchids, gold thread and the carnivorous sundew and pitcher plants, with smatterings of shrubs like bog laurel, Labrador tea, leatherleaf, sheep laurel, bog rosemary and swamp azalea. the bog also provides habitat for many mammals including bears, otters, bobcats, beavers, porcupines, minks and snowshoe hares. The Nature Conservancy manages the preserve with the volunteer assistance of a local Stewardship Committee and the Kettle Creek Environmental Education Center. The North Wood Trail and the Fern ridge Trail in the upland woods are open to the public for self-guided walks. Because of its fragile nature, the bog can only be visited during regularly scheduled walks conducted by the Kettle Creek Environmental Education Center. Private walks are also available to groups upon request. Cost for public walks are $6/non-members, or $4/EE Center members, children under 12 or for Nature Conservancy members, for management costs is requested. Please note that pets are not allowed on bog trails.
