After the death of the owners, their family preserved Glynwood Farm, making it the site of a not-for-profit organization dedicated to rural conservation. In 1995, the Open Space Institute purchased Glynwood Farm, a 957-acre estate, in an effort to preserve one of the last untouched woodlands in the lower Hudson River Valley. In this $6.25 million purchase, more than 700 acres of the purchase were added to the adjacent Clarence Fahnestock State Park, completing the effort by the Open Space Institute to expand the protected lands in the Hudson Highlands a mountain range bisected by the Hudson River. The purchase was made with a grant provided by the Lila Acheson and DeWitt Wallace Fund for the Hudson Highlands through a trust set up in 1983 to preserve unspoiled parts of the Hudson Valley by the founders of Reader's Digest. The 230-acre core of the estate, of cow pastures, farms and houses, remained a farm and became Glynwood Center.
