Mianus River Gorge
The Mianus River Gorge is a 755-acre (3.06 km2) nature preserve jointly owned by the Nature Conservancy and the Mianus River Gorge Preserve. It is located in Bedford, New York. The first 60 acres (0.24 km2) were purchased by the Preserve, with help from the Conservancy, their first land preservation deal. It has grown over the years and is still managed by the Preserve. In March 1964, it was designated a National Natural Landmark for its old growth climax hemlock forest and the gorge of the Mianus River.
In 1990, 17 acres (69,000 m2) were donated as part of a development deal
The gorge is a periglacial formation, carved by streams as the glacier retreated. It contains several types of bedrock including Bedford Augen Gneiss (an igneous intrusion from the Late Devonian period), Hartland Schist, Precambrian and Cambrian gneiss and quartzite. Cameron's Line passes through the preserve.
Wildlife and vegetation
In 2003, the Preserve began to manage its deer population via limited bow hunting. They did so decrease the risk of excessive deer populations causing damage to the vegetation. They believed that very small scale reductions could effectively manage the population without adversely affecting neighboring populations due to the rose petal hypothesis of deer populations.
There are numerous species of trees, shrubs, vine, herbs, and ferns.
It is open from April to November, 8:30am to 5pm. There are approximately 5 miles (8.0 km) of well marked hiking trails.
