Often it is preferable to protect the entire woodlot or farm, as the case may be. If the property includes a residence, farm buildings, and other structures, it is best to exclude those areas from the easement, so that the landowner is free to exercise the rights to repair, improve, or replace existing structures on the property outside the confines of the easement. In some circumstances, it may make sense for the landowner to exclude some portion of the property for future house lots to convey to family members or as a financial contingency. The location of an excluded area is determined jointly by the landowner and the easement holder, and should not detract from the overall conservation objectives for protecting the property. Sometimes a boundary survey is required to create a property description for the excluded area(s).
