Entity: Instance Entity Definition: An instance is the recorded occurrence in the ONHI database of an individual or group of individuals (population or subpopulation) of a species.
Associated Instance Attributes:
COMNAME Data type: text; Format: character; Value range: n/a; Description: Common name of species. See NAME, below. Reference: Procedures Manual, Oklahoma Natural Heritage Inventory Biological Diversity Database.
GRANK: Data type:text; Format: alphanumeric; Value range: G[1-5][T][Q,1-5] Description: Global (G) Rank. An index of the status and distribution of an element throughout its known range; 1 is most threatened and 5 is most secure or common in abundance. Two global ranks can be used to indicate a range, i.e. G3G4. Used in conjunction with State (S) Rank: See SRANK below. Reference: See www.biosurvey.ou.edu/species.html 'Guide to Rare Species Status and Rarity Ranking Codes'.
LASTOBS Data type: text; Format: YYYY-MM-DD; Value range: n/a; Description: Last observed date. Date of most recent record in the database for associated species at a given site. Reference: Procedures Manual, Oklahoma Natural Heritage Inventory Biological Diversity Database.
NAME Data type: text; Format: character; Value range; n/a; Description: Scientific name commonly in use in the state for the element; genus, species and subspecies name (if any). Reference: Procedures Manual, Oklahoma Natural Heritage Inventory Biological Diversity Database.
ORGTYPE Data type: text; Format: character; Value range: Fish, Amphibian, Mammal, etc. Description: Organism type. Commonly used term referring to the taxonomic class to which the element belongs. Reference: Procedures Manual, Oklahoma Natural Heritage Inventory Biological Diversity Database.
PRECISION Data type: text; Format: character; Value range: G,M,S; Description: An index of horizontal accuracy. G = species occurrence probably occurs within an approximate area of 50 square miles of mapped location at 1:24,000 scale; M = species occurrence probably occurs within an approximate area of 7 square miles (about 1.5 mile radius) of mapped location at 1:24,000 scale; S = species occurrence probably occurs within 3 acres of the mapped location. This index is brought about by varying quality of location information provided by data sources. Vague or poorly described locations are of necessity mapped with less precision than are those locations having detailed description.
