Adirondack Park State Land

New York State has one of the oldest land preservation programs in the United States ...

Over a century ago, New Yorkers established the Forest Preserve. An act of the Legislature in 1885 declared that State-owned lands in eight Adirondack and three Catskill View from Indian Falls in the Adirondack High Peakscounties should "be forever kept as wild forest lands." Further, the land could not be sold or leased.

The Act was a notable beginning, but it was inadequate to stop those who abused the land, and the struggle to preserve the forests continued. Dams were proposed which would have flooded many of the deeper forested valleys. Finally, in 1892, the Adirondack Park was created to encompass both the Forest Preserve and private lands in the central region. The State Constitution of 1895 redefined the Forest Preserve, adding that lands shall not be cut, "nor shall the timber thereon be sold, removed, or destroyed."

Staff map documenting 1972 snowmobile trail use on Forest Preserve

The map was prepared by Agency staff to document the extent of snowmobile trails designated by the DEC on Forest Preserve in 1972 at the time of the Adirondack Park State Land Master Plan's adoption. The maps in the DEC 1972 snowmobile brochure entitled "Snowmobile Trails in New York" LF-P2 (10/72) were digitized at a scale of 1:24,000 utilizing best available sources for confirmation of trail locations. The resulting park-wide map indicates that an estimated 743 miles of designated snowmobile trails existed on Forest Preserve in 1972. see map...
