Description:
Abstract:
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.
Purpose:
The Natural Diversity Database Areas is 1:24,000-scale data. It depicts the approximate locations of state and federal listed species and significant natural communities. This data is intended to be used as a pre-screening tool to identify potential impacts to sensitive species. The data may also be used to target areas of potential conservation interest. More information can be obtained by submitting written environmental review request to the Natural Diversity Database. Not intended for maps printed at map scales greater or more detailed than 1:24,000 scale (1 inch = 2,000 feet.)

Data_Quality_Information:
Logical_Consistency_Report:
Polygon features conform to the following topological rules. Polygons are single part. There are no duplicate polygons. Polygons do not self overlap. Polygons do not overlap other polygons. Establishment of logical consistency was performed by the State of Connecticut, Department of Energy and Environmental Protection using ESRI ArcGIS software using an automated process to create and control feature topology. No automated procedures or tests were performed to guarantee desired topology other than visual inspection.
Completeness_Report:
The Natural Diversity Database is the central repository for state listed species data in the state. Data recruitment is on-going. The data provided to the database is not necessarily the result of statewide or comprehensive field surveys. The species selected to be included in this data product are those officially listed in the Connecticut Endangered Species Regulations at the time the layer was created. The layer is complete in the sense that it accurately reflects the data submitted and accepted by the Natural Diversity Database at the time the State of Connecticut, Department of Energy and Environmental Protection created the layer.  This data is updated every six months.
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
The horizontal positional accuracy of this data is unknown. The original locations have been purposely shifted and buffered to protect the exact locations and to create this generalized layer.  Some polygons represent observations that are transient or temporal in nature and are not easily recoverable on the ground (e.g. animal breeding or nesting sites).

Process_Step:
Process_Description:
The Natural Diversity Database tracks data on the locations of state listed species and significant natural communities.  Polygons are created and stored using NatureServe's Natural Heritage Methodology. Polygons are extracted from the database to create this generalized product called the Natural Diversity Database Areas.  Polygon centroids are calculated from the original data for selected terrestrial species and communities and a random X,Y coordinate shift is applied to each record.  The shifted coordinates are then projected and buffered by 0.25 miles to create generalized locations.  Selected aquatic, riparian and coastal species and community records are intersected with riparian segments that have been buffered by 300 feet. Topology rules are created to ensure that all of the original polygons are covered by the new generalized areas. All areas are merged together.
