Title: North Carolina 2016 ESI T_MAMMAL Polygons
Short Name: North Carolina 2016 ESI T_MAMMAL Polygons
Status: Completed
Publication Date: 2016

This data set contains sensitive biological resource data for horses and federally and/or state endangered, threatened, or rare small mammals. Vector polygons in this dataset represent vulnerable occurrences and general distribution. Species-specific abundance, seasonality, status, life history, and source information are stored in associated data tables (described below) designed to be used in conjunction with this spatial data layer. This data set is a portion of the ESI data for North Carolina. As a whole, the ESI data characterize the marine and coastal environments and wildlife by their sensitivity to spilled oil, and include information for three main components: shoreline habitats, sensitive biological resources, and human-use resources.


The ESI data are intended to provide baseline environmental data for oil spill planning and response. The Clean Water Act with amendments by the Oil Pollution Act of 1990 requires response plans for immediate and effective protection of sensitive resources. The ESI data may be appropriate for many other coastal management efforts, though the original intent should be kept in mind.

Data Set Information

Data Set Scope Code: Data Set
Data Set Type: GIS Files
Maintenance Frequency: As Needed
Maintenance Note:

Data content is considered static once published. However, if issues with the Geodatabase linkages or table contents are identified, the Geodatabase and/or the associated Map Document may be updated. Assure most current data is being used by downloading from and/or comparing modification dates provided at this site.

Data Presentation Form: Map (digital)
Entity Attribute Overview:

The primary attribute tables associated with the ESI biology data are BIOFILE, SOURCES, and BREED_DT. The geographic data layer containing biological resource information (in this case, T_MAMMAL) is linked to the BIOFILE using the RARNUM field. There is a many-to-many relationship from the data layer to the BIOFILE, as an RARNUM may be repeated in several geographic features. Likewise, in the BIOFILE, the same RARNUM may appear in multiple records, representing a unique combination of species found in that region. To be represented by the same RARNUM, these species groups must also share the same seasonality, concentration, mapping qualifier, and source information. The items in the BIOFILE are ELEMENT, SUBELEMENT, NAME, GEN_SPEC, S, F, STATE, S_DATE, F_DATE, GRANK, GRANKDATE, MAPPING_QUALIFIER, CONC, JAN, FEB, MAR, APR, MAY, JUN, JUL, AUG, SEP, OCT, NOV, DEC, BREED1, BREED2, BREED3, BREED4, BREED5, RARNUM, G_SOURCE, S_SOURCE, and BREED. The G_SOURCE and S_SOURCE fields provide links to the SOURCES table, where object level source information is available. The BREED field is the link to the BREED_DT table, where searchable breed information is provided. The links to both of these tables are also many-to-many. During the collection of the ESI data, six relational data tables are used to store the attribute data. These are the BIORES, BREED, SEASONAL, SOURCES, SPECIES, and STATUS tables. When we create new ESI data, we populate these tables to maintain the integrity of the data collected. Once completed, all information populating these tables is collapsed into the BIOFILE to ease data queries and general usability of the final product.

Data Access Constraints:


Data Use Constraints:

DO NOT USE MAPS FOR NAVIGATIONAL PURPOSES. Management boundaries are not to be considered legal boundaries. Edges may have been altered for cartographic processes. Note that the ESI database should not be used to the exclusion of other pertinent data or information held by state or federal agencies or other organizations. Likewise, information contained in the database cannot be used in place of consultations with environmental, natural resource, and cultural resource agencies, or in place of field surveys. Recognize that the information contained in the ESI database represents known concentration areas or occurrences of natural, cultural, and human-use resources, but does not necessarily represent the full distribution or range of each species or resource. This is particularly important to recognize when considering potential impacts to protected resources, such as endangered species, wetlands, etc. Besides the above warnings, there are no use constraints on these data. Acknowledgment of the originators, publishers, contributors, and sources listed would be appreciated in products derived from these data.

Technical Environment


The software package used to develop the atlas is Environmental Systems Research Institute's ArcGIS for Desktop 10.2(R). The hardware configuration is PCs with Windows Operating System 7. The following Geodatabase Feature Classes are included in the data set: ANNO, AOI, BENTHIC, BIRDS, BIRDSPT, ESIL, ESIP, FISH, HABITATS, HABITATSPT, HERP, HYDROL, HYDROP, INVERT, M_MAMMAL, MGT, SOCECONL, and SOCECONPT. Associated data tables are BIOFILE, BREED_DT, SOC_DAT, AND SOURCES.

Data Quality


A multi-stage error checking process is used to verify both attribute accuracy and logical consistency throughout data production. The process includes a standardized data entry methodology, data review by in-house and external resource experts, a final Quality Assurance/Quality Control (QA/QC) process, and multiple automated logical consistency checks. Quantitative data (such as densities, counts, abundances, or concentrations) provided by resource experts for inclusion in the data set may vary widely in attribute accuracy, depending upon the methodology used to collect and compile such data. For a more detailed evaluation of source data attribute accuracy, contact the sources listed in the Lineage section.

Horizontal Positional Accuracy:

Spatial components for the biological data layers can come from expert interviews, hardcopy, or digital sources. Some of the spatial components of the biological data layers may have been developed using regional experts who estimate concentration areas. It is difficult to estimate the positional accuracy of such data, except to state that they are compiled on digital base maps with a scale of 1:24,000 or larger. Some of the spatial components of the biological data sets are developed from pre-existing digital or hardcopy sources and reflect the positional accuracy of these original data. Note that biological resource data by their very nature are considered "fuzzy", and this should be understood when considering the positional accuracy of vector digital objects representing these resources. See the Lineage and Process_Description sections for more information on the original source data and how these data were integrated or manipulated to create the final data set.

Completeness Report:

These data represent a synthesis of digital data and expert knowledge on terrestrial mammal occurrences. These data do not necessarily represent all terrestrial mammal occurrences in North Carolina. The following species are included in this data set: (Species_ID, Common Name, Scientific Name or n/a if not applicable): 274, Buxton Woods white-footed deermouse, Peromyscus leucopus buxtoni; 275, Horse, Equus caballus; 288, Dismal Swamp bog lemming, Synaptomys cooperi helaletes; 289, Florida eastern woodrat, Neotoma floridana floridana; 290, Pungo white-footed deermouse, Peromyscus leucopus easti; 291, Star-nosed mole, Condylura cristata pop. 1.

Conceptual Consistency:

A multi-stage error checking process, described in the above Attribute Accuracy Report, is used to verify both attribute accuracy and logical consistency throughout data production. This process includes multiple automated logical consistency checks that test the files for missing or duplicate data, rules for proper coding, GIS topological consistencies, and SQL SERVER(R) to ArcGIS(R) consistencies. A final review is made by the GIS manager, before the final Geodatabase and metadata are created. After the data are delivered to NOAA, they are again subjected to several consistency checks, and processed into the final delivery format.

Process Steps

Process Step 1

CC ID: 511400

The terrestrial mammals are limited to rare coastal and special status species. These are: Buxton Woods white-footed deer mouse (state special concern, federal species of concern), Florida eastern woodrat (state threatened), Pungo white-footed deer mouse (state special concern), star-nosed mole (state special concern), and Dismal Swamp southern bog lemming (state significantly rare). The deer mice are localized subspecies that live in dunes along North Carolina\x92s barrier islands. The woodrat uses moist hardwood forests in the southeastern Coastal Plain. The bog lemming can be found in open wetland habitat such as damp fields and marsh edges. The star-nosed mole is semi-aquatic and is found in wetland habitats such as swamps, bogs, and marshes. Digital polygon data from NC NHP were used to map rare and special status terrestrial mammals. Historical and very low accuracy locations were not mapped. Non-native, feral horses known as Banker ponies or horses occur along the barrier islands of North Carolina. The largest of these herds is found on Shackleford Banks (SB), the southern-most barrier island in Cape Lookout National Seashore, and a smaller herd occurs nearby on the Rachel Carson Reserve (RCR). These herds are managed as part of the cultural landscape, having descended from colonial Spanish horses brought to the islands centuries ago (SB) as well as more recent releases (RCR). They are protected by federal (SB) and state and local (RCR) laws. The general distributions of these herds were reviewed by NPS and NC Coastal Reserve personnel. There are several rare and listed bat species that are present within the atlas area. These species are; northern long-eared bat (state significantly rare, federally threatened), Rafinesque\x92s big-eared bat (state special concern and federal species of concern), southeastern bat (state special concern and federal species of concern), northern yellow bat (state special concern), little brown bat (state significantly rare), tricolored bat (state significantly rare). Bats in North Carolina have been devastated by white-nose syndrome, the primary threat to bats in this area. While these species may not be directly impacted by an oil spill, human disturbance to roosts and hibernation areas is considered a secondary threat. There was not enough data to adequately map the distribution of rare bats in the North Carolina coastal plain. Known roosts and hibernacula occur predominantly in the mountains and none are shown in this AOI. The contact information for the regional bat expert has been included in the table below. Semi-aquatic furbearing mammals live in coastal wetland habitats vulnerable to oil spills. Mink and northern river otter are broadly distributed in the Coastal Plain of North Carolina. Beaver and muskrat are also widespread throughout the river systems, although muskrats are rare in southeastern North Carolina coastal areas. Due to their broad distribution and lack of specific concentration areas, these species were not mapped. See the Lineage section for additional information on the type of source data for this data layer. The ESI, biology, and human-use data are compiled into the standard ESI digital data format. A second set of interviews with participating resource experts are conducted to review the compiled data. If necessary, edits to the T_MAMMAL data layer are made based on the recommendations of the resource experts and digital data are created.
