The Conservancy's mission is "to permanently protect the fertile soils, range lands, open space and biological resources, and to support a viable agricultural economy, in the Tri Valley area. The Conservancy accomplishes this mission by providing landowners with a flexible, voluntary alternative to subdividing or developing their property. One facet of the Conservancy's work is acquisition . Working with willing landowners, the Conservancy acquires property development rights through the legal arrangement of a conservation easement. In doing so, the Conservancy ensures that a property will be protected from future development. Another facet of the Conservancy's work is the ongoing stewardship associated with each easement, including annual property visits and consultation with property owners about the terms of their easement.
