This land preservation agreement was donated by the Phillies Bridge Farm Project, Inc. in 2003 to protect valuable soils, wetlands, woods, and the rural character of Gardiner. The agreement is co-held by the Wallkill Valley Land Trust and its partner the Open Space Institute.

In December 1992, the Wallkill Valley Land Trust received the donation of the Finn Easement from Anne and Bill Finn. This is on eight and a half acres in Gardiner, running along the Shawangunk Kill.  Fields and habitat are preserved through this conservation easement.

The Greene Easement, the first easement completed by the Land Trust, was donated by Trina Greene in June 1989. It is a seven acre parcel in Gardiner along the Wallkill River. It provides lovely views and protects both habitat and water quality.

The Katz–Hollander Easement was donated by Joe Katz and Sue Hollander in August 1995. It preserves 65 acres of fields and woods in Gardiner. This includes almost half of a new meadow with a stream running down the middle that used to be Hedden's Lake until the dam broke.

This land preservation agreement, protecting 69 acres of working farmland and woods with much frontage along the Wallkill River, was donated by Vals Osborne in 2004. This is part of the property bought years ago by her father.
