About the Open Space Institute

Sterling Forest

The Open Space Institute protects scenic, natural and historic landscapes to provide public enjoyment, conserve habitat and working lands and sustain communities.

Founded in 1974 to protect significant landscapes in New York State, the Open Space Institute is a leader in environmental conservation. OSI has partnered in the protection of nearly 2.2 million acres in North America, from Alabama up the spine of the Appalachians to southeastern Canada. All of OSI’s work is directed by a consistent strategy emphasizing permanent protection on a landscape-level scale. Each discrete transaction, whether buying a conservation easement on a family farm in the Hudson River Valley or helping fund the purchase of 100,000 acres in Maine, represents an effort to align the pieces of the landscape puzzle and prevent fragmentation.

We gratefully acknowledge that much of OSI’s work in New York State is accomplished through the Open Space Land Trust, Inc, which received a permanent fund from the Lila Acheson and DeWitt Wallace Endowment in 2001.
