Mashomack Preserve is a natural area of nearly 2,100 acres which encompasses diverse habitats necessary for the survival of many species of plants and animals. Only 90 miles from New York City and comprising one third of Shelter Island, the Preserve was acquired by The Nature Conservancy in January of 1980. Mashomack was purchased to stop development of this nearly pristine peninsula and to protect one of the most dense populations of breeding ospreys on the east coast. In addition, Mashomack occasionally harbors nesting populations of the endangered piping plover and least tern, as well as a number of rare plants.

 Edged in white by 10 miles of coastline, Mashomack is an area of magnificent scenic beauty. Its combination of interlacing tidal creeks, woodlands, fields and coastline makes it a superb wildlife habitat. The extensive salt marshes of Mashomack are vitally significant ecologically, being the breeding ground and nursery for the smallest links in the marine chain of life.

 The Pine Swamp complex at the western edge of the Preserve has been desiginated a freshwater wetland of unique local importanceî by the New York State Department of Environmental Conservation.

 Fourteen hundred acres of upland oak and beech forest are now being allowed to develop into an old-growth forest, a habitat scarce in the Northeast. Open, grassy meadows provide another contrasting habitat.

All these areas are oroterted and managed to provide a safe haven for all native species.

Experiencing Mashomack
 Mashomack is a museum of life in process, a sanctuary where the natural cycles of flora, fauna, and ecosystems are allowed to complete themselves free from human interference. The Nature Conservancyís mission at Mashomack Preserve is to maintain its full array of natural communities and species, and to restore to health those that have been disturbed by human action. To this end, the Preserve is made available for compatible scientific research, educational programs, and passive recreational use.

 We invite you to visit and explore Mashomack and to experience its unique beauty. In order to protect its delicate resources, we ask you to abide by the following rules:

 * Only Hiking Allowed
 Jogging, bicycling, and horseback riding may disturb flora or fauna and cause excessive wear on the trails.

 * Remain On Marked Trails
 Exploration of unmarked areas may result in disturbance of sensitive species and habitats as well as increased exposure to ticks.

*  No Collecting Allowed
 Accidental removal of rare specimens can result, diminishing the stability of nature and the enjoyment of later visitors.

*  No Pets Allowed
Domestic animals can disrupt and damage wildlife, or may become lost.

* Everything Carried In Must Be Carried Out
 Help keep Mashomack free of litter for habitat protection and your enjoyment.

*     Check Yourself Periodically For Ticks
 Tuck pants into socks, tuck shirts into pants, and button cuffs. Stay toward the center of roads and trails; avoid bushy, grassy areas. Use of repellents is recommended.
