Natural Heritage Screening Coverage
<DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>There are two separate components to the NH Screening Coverage...</SPAN></P><P><SPAN>1) Conservation Sites represent key areas of the landscape of protection and stewardship action because of the natural heritage resources and habitat they support. Conservation sites are polygons built around one or more rare plant or animal, or significant natural community or geological feature. Sites are designed to include the element and, where possible, its associated habitat, and buffer or other adjacent land thought necessary for the element's conservation. For rare aquatic species we define Stream Conservation Units (SCUs), which identify stream reaches that contain aquatic natural heritage resources, including upstream and downstream buffer and tributaries associated with this reach. There are almost 2000 terrestrial and SCU site records in the Conservation Sites coverage; these sites encompass all viable, recently-verified element occurrences documented in our databases. Conservation Sites and SCUs are given a biodiversity significance ranking based on the rarity, quality, and number of natural heritage resources they contain. Conservation Sites can be used to identify land management needs and protection priorities. They can also be used as a screening tool, to identify potential conflicts with development activities, and they can be used for proactive planning to ensure that development projects successfully avoid or enhance natural heritage resources.</SPAN></P><P><SPAN>2) General Location Areas for Natural Heritage Resources represent the approximate locations of documented natural heritage resource occurrences that were not incorporated into Conservation Sites, either because they are poor quality, their location was not precisely identified, or they have not been reverified in over 20 years. These approximate locations are included in the Screening Coverage because they indicate areas with relatively high potential for natural heritage resource occurrences to be redocumented. Depending on the apparent suitability of local habitat, DCR-NH may recommend biological surveys when reviewing projects that intersect these locations. Some general location areas are represented by circular polygons of 0.5 mi. radius. Some are regular polygons. For these records, a review of recent aerial photography in conjunction with known habitat needs for the element identified potential habitat that might exist within the limits documented in the original occurrence.</SPAN></P></DIV></DIV></DIV>
The NH Screening Coverage is a valuable tool for conservation planning, land stewardship, and for screening projects that have potential for impacting natural heritage resources. The layer can facilitate project permitting by identifying biologically sensitive areas before projects are submitted to permitting authorities. For example, potential impacts to endangered species can be identified early in the planning process, while there is still an opportunity to modify a project to avoid the impacts. Early coordination is key to ensuring protection of an area's natural heritage resources and accelerating the permit review process. Any absence of data may indicate that an area has not been surveyed, rather than confirm that the area lacks natural heritage resources. NH Screening Coverage boundaries should not considered legal boundaries.

Data is believed to be logically consistent.
Data is a continual work in progress.
Data is believed to be consistent with National Map Accuracy Standards of 1:24,000. Thus, mapped features should be within 12.2 meters of the true locations for about 90% of the features tested.
