Data Dictionary for Occurrence Data Downloads

Source Feature Occurrence Records: source.shp or the results tab in the results.xlsx file

Distributed in data requests as individual observations of a single species or vegetation community at a specific location on a specific date, represented by polygons depicting the locational uncertainty distance in meters. Very precise location information will usually result in smaller polygons. Particular attention should be paid to the ID_CONFID and corresponding ID_NOTES fields when evaluating Source Feature data.


Sensitive Data Policy

Records are considered sensitive and therefore only distributed at the township scale if they meet one or more of the following criteria:

  • Record occurs on private land and is not documented in publicly available references, though WYNDD has permission from the land owner to archive and distribute at the township level.
  • Record was donated to WYNDD and the donor has requested that it be treated as sensitive.
  • Record contains a biologically sensitive component.

eeorep only    ssource only   *Not distributed for sensitive records or township scale requests 

ATTRIBUTE
DEFINITION
FEATURE_ID
Unique identification number for the shape (original point, line, or polygon) representing the Element Occurrence or Source Feature
OBS_IDs
Unique identification number for each observation within a Source Feature
DATA_SENS
Record contains sensitive data:
Y - Yes, records released at township scale only
N - No, records may be released at the precise scale
AREA
AREA_TRs = request or buffer township for township scale requests
Request or Buffer Area
Records within 4 miles of the request area are usually included in smaller scale data requests
Request - Record intersects the request area
Buffer - Record intersects the buffer area only
ELCODE
Element code assigned to species or vegetation community by NatureServe, consisting of the following 10-character structure:
1.    A = vertebrate animal, P = vascular plant, C = community, I = invertebrate animal, N = nonvascular plant or fungus, G = geologic, O = other
2.     Plants: P = pteridophyte (ferns and fern allies), G = gymnosperm, D = dicot,
M = monocot; vertebrate animals: A = amphibian, B = bird, F = fish, M = mammal, R = reptile)
3.     Plants: 1st digit of 3-digit family code, vertebrate animals: birds P = passerine, N = nonpasserine; fish - A = lampreys and hagfish, B = sharks and rays, C = bony fishes; for mammals, amphibians, and reptiles this character was not used to represent any information and was generally filled with an "A" merely as a placeholder
4.     Plants: 2nd digit of 3-digit family code, vertebrate animals: order code
5.     Plants: 3rd digit of 3-digit family code, vertebrate animals: family code
6.     Plants and animals: 1st digit of 2-digit genus code
7.     Plants and animals: 2nd digit of 2-digit genus code
8.     Plants and animals: 1st digit of 2-digit species code
9.     Plants and animals: 2nd digit of 2-digit species code
10. Plants and animals: subspecies code
