Following are links to four Authority Files with the standard categories to be used when documenting:
- the major habitats a taxon occurs in;
- the major threats to the taxon (past, present and future);
- what conservation actions are in place or are needed for the taxon; and
- if the species is utilized locally, nationally or internationally.
More detailed descriptions of the terms are being developed, and a draft version of these is included in the Habitats and Conservation Actions Authority Files. The Authority Files are periodically reviewed and updated based on users comments, hence a numbering system has been adopted to allow users to check if they are using the most current version.
Users must take careful note of the comments at the top of each file, in particular, they should note that there is a major difference in how the hierarchy for the habitat classification operates compared to the classifications for the threats and conservation measures.
