The Mianus River Gorge is a 935abbr=NaNabbr= nature preserve in Bedford, New York jointly owned by The Nature Conservancy and Mianus River Gorge, Inc.. The first 60acres were purchased by the Preserve, with help from the Conservancy, their first land preservation deal.[1] It has grown over the years and is still managed by Mianus River Gorge, Inc. In March 1964, it was designated a National Natural Landmark for its old growth climax hemlock forest and the gorge of the Mianus River.[2]
In 1954, Gloria and Anthony Anable[1] reached out for help from The Nature Conservancy which pledged $7,500 to help purchase 60acres of land in the gorge, its first land preservation purchase.[3]
In 1990, 17acres were donated as part of a development deal.[4]
In 2007, The Nature Conservancy purchased 8acres of adjacent wetlands to protect the gorge and its watershed.[5]
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[6]), Hartland Schist, Precambrian and Cambrian gneiss and quartzite. Cameron's Line passes through the preserve.
The old Hobby Hill pegmatite quarry is located in the northern section of the preserve.[7] The Havenmeyer Falls is also part of the preserve.
In 2003, the Preserve began to manage its deer population via limited bow hunting. They did so to 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.[8] There are numerous species of trees, shrubs, vines, herbs, and ferns within the preserve.[9]
The preserve is open from April 1 to November 30, 8:30 a.m. to 5 p.m. There are approximately 3miles of well-marked hiking trails.[10]
