Tannersville Cranberry Bog
Encyclopedia
The Tannersville Cranberry Bog or Cranberry Swamp, is a sphagnum
bog
on the Cranberry Creek in Tannersville, Pennsylvania
. It is the southernmost boreal bog east of the Mississippi River
, containing many black spruce
and tamarack trees at the southern limit of their ranges. Technically, it can be classed as an acid fen
, as it receives some groundwater flow. The site was designated a National Natural Landmark
in December 1974. It was purchased by The Nature Conservancy
and the Conservation and Research Foundation in 1956. Like many bogs, its terrain presents an image of solidity, but a liquid mass of decaying peat
lies beneath a six-inch (152 mm) layer of sphagnum and a network of supporting tree roots. However, this bog may be viewed conveniently from a floating walkway.
. In 1956 The Nature Conservancy
acquired the first 62.5 acres (252,928.8 m²) for protection. The area held by this organization has increased by gifts and purchases to over 1000 acres (4 km²), and adjoins on additional public lands.
(Pocono Mountain Office, P.O. Box 55, Long Pond Road, Long Pond, PA 18334, telephone (570) 643-7922). Other trails in the upland woods adjacent to the bog are open to the public without special scheduling.
Sphagnum
Sphagnum is a genus of between 151 and 350 species of mosses commonly called peat moss, due to its prevalence in peat bogs and mires. A distinction is made between sphagnum moss, the live moss growing on top of a peat bog on one hand, and sphagnum peat moss or sphagnum peat on the other, the...

History
The bog began as a "kettle lake" formed approximately 10,000 years ago by a portion of the retreating Wisconsin Glacier (named according to geologic epoch, not location), which initially covered a depth up to the top of the current forest canopy. With restricted air and nutrient flow, sphagnum moss grew out into the lake, eventually forming a layer of peat over 40 feet (12.2 m) thick. While young bogs may contain an "eye" of open water where sphagnum has not yet reached, no such feature remains in the Tannersville Cranberry Bog. However, a narrow strip of open water marks the course of the Cranberry Creek, where the water is less acidic.Flora

Preservation
The call for preservation of this habitat began with William A. Niering, who as a child visited the bog as the nephew of its owner and was moved ultimately to become a widely recognized authority on bog ecology. The practical benefits of the bog were evident during the Flood of 1955, when bridges downstream of the bog were spared from the massive damage done in much of the PoconosThe Poconos

acquired the first 62.5 acres (252,928.8 m²) for protection. The area held by this organization has increased by gifts and purchases to over 1000 acres (4 km²), and adjoins on additional public lands.
Public visitation
Initially, public visitation to the land was not permitted. However, in the 1980s the Monroe County Conservation District negotiated access to the bog for purposes of public education. A floating boardwalk was constructed and expanded to 1450 feet (442 m) in 1993, which consists of treated lumber supported by floating barrels. Planks are now replaced as needed with a recycled plastic product. Leaving the walkway is definitely not recommended - hikers would sink to the knee or worse in smelly peat, would encounter hazardous poison sumac, and one tour leader who participated in construction of the walkway described movement through the brush as requiring an "army crawl". During spring months all fourth grade public school students in Monroe County are given the opportunity to visit the bog as a field trip. Parents should note that some poison sumac may be within arm's reach of the walkway, and one fourth grader was hospitalized after intentional contact with it. Additionally, groups of visitors are allowed to visit on walks scheduled by the Monroe County Environmental Education Center, 8050 Running Valley Road, Stroudsburg, PA 18360, telephone (570) 629-3061. These walks occur on summer Wednesdays and Sundays, although more occasional winter walks are available. Access may also be granted by special permission of The Nature ConservancyThe Nature Conservancy

(Pocono Mountain Office, P.O. Box 55, Long Pond Road, Long Pond, PA 18334, telephone (570) 643-7922). Other trails in the upland woods adjacent to the bog are open to the public without special scheduling.
