Open Space Institute

The Open Space Institute (OSI) protects scenic, natural, and historic landscapes to ensure public enjoyment, conserve habitats, and sustain community character.

OSI achieves its goals through land acquisition, conservation easements, regional loan programs, fiscal sponsorship, creative partnerships, and analytical research.

OSI has protected more than 100,000 acres through our New York Land Program, by means of direct acquisition and conservation easements in the State of New York.

The Conservation Finance Program, since its inception in 2000, OSI has made more than 70 loans and grants for nearly $80 million to protect 1.6 million acres valued at over $530 million.

OSI's Research Program influences land use policy and practice through research, communication and training.

All of OSI’s work is directed by a consistent conservation strategy that emphasizes permanent protection on a landscape-level scale. Each discrete transaction, whether buying a conservation easement on a small 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 prevents fragmentation, which disrupts key wildlife corridors, impairs water and air quality, and diminishes the beauty and scenery of natural areas.

We gratefully acknowledge that much of OSI’s work in New York State is accomplished through the Open Space Conservancy (OSC), OSI’s land acquisition affiliate, which received a permanent fund from the Lila Acheson and DeWitt Wallace Endowment in 2001.
