With restricted air and nutrient flow, sphagnum moss grew out into the lake, eventually forming a layer of peat over 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.

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

. In 1956 The Nature Conservancy acquired the first for protection. The area held by this organization has increased by gifts and purchases to over , 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 in 1993, which consists of treated lumber supported by floating barrels. Planks are now replaced as needed with a recycled plastic product.
