Limestone woodlands are an ecological community type identified by the New York Natural Heritage Program. These communities are characterized by shallow soil over limestone bedrock. Two northern white-cedar (Thuja occidentalis) limestone woodland stands were surveyed in Point au Roche State Park (Clinton County), one at Middle Point and the other at Ram's Head. Both stands were dominated by white-cedar and both stands were essentially even-aged. The Ram's Head stand was determined to be the older of the two stands. The structure of these stands indicates that they were probably regenerated by a clearcut. Northern white-cedar survivorship was determined for the Middle Point stand based on snag density per diameter at base height (dbh) class. The northern white-cedars showed a "type II" survivorship curve, with relatively constant mortality rates between 26 and 79 years of age. Although northern white-cedar is a commercially valuable species, the white-cedar limestone woodlands at Point au Roche State Park should be protected for their ecological value.Description
