Preservation development is a model of real-estate development that addresses farmland preservation. It shares many attributes with conservation development, with the addition of strategies for maintaining and operating productive agriculture and silviculture, often in perpetuity. A preservation development is a planned community that allows limited, carefully designed development (typically housing) on a working farm, while placing the majority of productive land under a system of easements and community governance to ensure a continuity of farming and environmental stewardship.
