High Quality Content by WIKIPEDIA articles! In the United States, a conservation easement (also called a conservation covenant or conservation restriction) is an encumbrance — sometimes including a transfer of usage rights (easement) — which creates a legally enforceable land preservation agreement between a landowner and a government agency (municipality, county, state, federal) or a qualified land protection organization (often called a "land trust"), for the purposes of conservation. It restricts real estate development, commercial and industrial uses, and certain other activities on a property to a mutually agreed upon level. The property remains the private property of the landowner.
