NH GRANIT Conservation/Public Lands StandardsThe NH GRANIT Conservation/Public Lands data layer contains a digital record of parcels of land of two or more acres that are mostly undeveloped and are protected from future development. Smaller parcels that adjoin previously mapped parcels or represent unique features, such as a bog or state-owned boat ramp, may also be included in the data layer. Several "levels of protection" are recognized, as follows: 1) Permanent conservation land. Land protected from development through conservation easement, restrictions, or outright ownership by an organization or agency whose mission includes protecting land in perpetuity; more than 50% of area will remain undeveloped. 2) Unofficial conservation land. Land owned by an agency or organization whose mission is not conservation, but whose intent is to keep the land for conservation, passive recreation, or educational purposes. Not permanently protected. 2A) Water supply lands. Lands owned or controlled by suppliers of public drinking water. Includes all supplies owned by a municipality or a subdivision of a municipality, and all private water systems that serve 500 people or more. 3) Unprotected public open space land. 4) Developed public land. Includes lands having active recreational use on more than 50% of the area, e.g. beaches, picnic areas. 9) Unknown. Note that some properties included in the data layer are privately owned and not open for public access. The Conservation/Public Lands data layer is updated periodically. Data gaps may occur if 1) a parcel has been protected since our last data update, or 2) a parcel was inadvertently overlooked during previous mapping phases. If you identify such gaps, please review the materials below and contact the GRANIT Conservation/Public Lands Data Manager.
