It allows you to continue to own and use your land and to sell it or pass it on to heirs. When you donate a conservation easement to a land trust, you give up some of the rights associated with the land. For example, you might give up the right to build additional structures, while retaining the right to grow crops. Future owners also will be bound by the easement's terms. The land trust is responsible for making sure the easement's terms are followed.
Conservation easements offer great flexibility.
An easement on property containing rare wildlife habitat might prohibit any development, for example, while one on a farm might allow continued farming and the building of additional agricultural structures. An easement may apply to just a portion of the property, and need not require public access. A landowner sometimes sells a conservation easement, but usually easements are donated. The amount of the donation is the difference between the land's value with the easement and its value without the easement. Placing an easement on your property may also result in property tax savings.
