Description: The Natural Diversity Database Areas is a 1:24,000-scale, polygon feature-based layer that represents general locations of endangered, threatened and special concern species and significant natural communities. The layer is based on information collected by DEEP staff, cooperating scientists, conservation groups and landowners. In some cases an occurrence represents a location derived from literature, museum records and specimens. These data are compiled and maintained by the DEEP Bureau of Natural Resources, Natural Diversity Database Program. The layer is updated every six months and reflects information that has been submitted and accepted up to that point. The layer includes state and federally listed species and significant natural communities. It does not include Natural Area Preserves, designated wetland areas or wildlife concentration areas. These general locations were created by randomly shifting the true locations of terrestrial species and then adding a 0.25 mile buffer distance to each point, and by mapping linear segments with a 300 foot buffer associated with aquatic, riparian and coastal species. The exact location of the species or community falls somewhere within the polygon area and not necessarily in the center. Attribute information includes the date when these data were last updated. Species names are withheld to protect sensitive species from collection and disturbance. Data is compiled at 1:24,000 scale. These data are updated every six months, approximately in June and December. It is important to use the most current data available.

Description: This layer includes polygon features that depict protected open space for towns of the Protected Open Space Mapping (POSM) project. Only parcels that meet the criteria of protected open space as defined in the POSM project are in this layer. Protected open space is defined as: (1) Land or interest in land acquired for the permanent protection of natural features of the state's landscape or essential habitat for endangered or threatened species; or (2) Land or an interest in land acquired to permanently support and sustain non-facility-based outdoor recreation, forestry and fishery activities, or other wildlife or natural resource conservation or preservation activities. The Towns involved in the POSM project are listed below. These towns are Andover, Ansonia, Avon, Beacon Falls, Bethel, Bethlehem, Bloomfield, Brookfield, Bolton, Canaan, Canterbury, Canton, Chaplin, Clinton, Colchester, Columbia, Coventry, Cromwell, Derby, East Granby, East Haddam, East Hampton, East Hartford, East Windsor, Ellington, Enfield, Essex, Farmington, Franklin, Glastonbury, Goshen, Granby, Groton, Guilford, Haddam, Hampton, Hartford, Hebron, Kent, Killingworth, Ledyard, Lisbon, Litchfield, Madison, Manchester, Mansfield, Marlborough, Meriden, Middletown, Monroe, Montville, Morris, New Canaan, New Fairfield, New Hartford, New Milford, Newington, Newtown, North Norwich, Stonington, Oxford, Preston, Pomfret, Prospect, Redding, Ridgefield, Rocky Hill, Salem, Scotland, Seymour, Simsbury, Somers, South Windsor, Southbury, Southington, Sprague, Sterling, Stonington, Suffield, Thompson, Vernon, Voluntown, Wallingford, Watertown, West Hartford, Weston, Wethersfield, Willington, Wilton, Windsor, Windsor Locks, Windham, Wolcott, Woodbridge, and Woodbury. Additional towns are added to this list as they are completed. The layer is based on information from various sources collected and compiled during the period from March 2005 through the present. These sources include but are not limited to municipal Assessor's records (the Assessor's database, hard copy maps and deeds) and existing digital parcel data. The layer represents conditions as of the date of research at each city or town hall. The Protected Open Space layer includes the parcel shape (geometry), a project-specific parcel ID based on the Town and Town Assessor's lot numbering system, and system-defined (automatically generated) fields. The Protected Open Space layer has an accompanying table containing more detailed information about each feature (parcel). This table is called Protected Open Space Dat, and can be joined to Protected Open Space in ArcMap using the parcel ID (PAR_ID) field. Detailed information in the Protected Open Space Data attribute table includes the Assessor's Map, Block and Lot numbers (the Assessor's parcel identification numbering system), the official name of the parcel (such as the park or forest name if it has one), address and owner information, the deed volume and page numbers, survey information, open space type, the unique parcel ID number (Par_ID), comments collected by researchers during city/town hall visits, and acreage. This layer does not include parcels that do not meet the definition of open space as defined above. Features are stored as polygons that represent the best available locational information, and are "best fit" to the land base available for each.
