Data Types

Data Types

The following data are provided for each species in the online searchable database:

Systematics

Species, genus, family, order, taxonomic authority, commonly-used synonyms, English and other common names (if any), and taxonomic notes (if needed, normally used to clarify difficult or confusing issues).

General Information

General text information on: geographic range, population (usually a subjective assessment of abundance in the absence of quantitative information), habitat and ecology, major threats and conservation measures (in particular noting occurrence in protected areas).

Red List Assessment

Based on the information above, the following is determined: IUCN Red List Category, IUCN Red List Criteria, Rationale for the Red List assessment, reason for any change from previous assessments (i.e., genuine change in status of species, new or better information available, incorrect information used previously, taxonomic change affecting the species, previously incorrect application of the Red List Criteria), current population trend (i.e., increasing, decreasing, stable, unknown), date of assessment, names of assessors, and any notes relating to Red Listing (e.g., any important issues in deciding the Category).

Preliminary species summary reports, distribution maps and global assessments were distributed to all the participants before the workshop to allow them to review the data presented and prepare any changes to the data.

Red List Assessment

Based on the information above, the following is determined: IUCN Red List Category, IUCN Red List Criteria, Rationale for the Red List assessment, reason for any change from previous assessments (i.e., genuine change in status of species, new or better information available, incorrect information used previously, taxonomic change affecting the species, previously incorrect application of the Red List Criteria), current population trend (i.e., increasing, decreasing, stable, unknown), date of assessment, names of assessors, and any notes relating to Red Listing (e.g., any important issues in deciding the Category).

Distribution Map

A geographic distribution map of the Extent of Occurrence for each species. The maps are in the form of polygons that join known locations. A species' distribution map can consist of more than one polygon where there is an obvious discontinuity in suitable habitat.

Habitat Preferences

Each species is coded against a standardised list of habitats, the IUCN Habitats Classification Scheme, and coded for suitability and relative importance.

Major Threats

Each species is coded against a standardised list of threats, the IUCN Threats Classification Scheme, and coded for whether the threat is acting in the past, present or future, or is an ongoing threat.
