Аnnex 1. Authority Files For Habitats, Threats and Conservation Actions and Utilization
This annex contains four Authority Files with standard categories to be used for documenting (a) the major habitats a taxon occurs in; (b) the major threats to the taxon (past, present and future); (c) what conservation actions are in place or are required for the taxon; and (d) information about the utilization of the taxon (locally, nationally or internationally). More detailed descriptors of the Authority File terms are being developed, and will be available in due course.
Приложение А. Местообитания (Habitats Authority File , Version 2.1)
This two-tiered habitat classification system is based on a climatic and biogeographic classification using Holdridge's life zones as a basis (see http://www.grid.unep.ch/data/grid/images_new/gnv005-1.gif). The aquatic habitats (inland, marine and artificial) are based primarily on the classification system of wetland types used by the Ramsar Convention (see http://www.ramsar.org/key_ris_types.htm). The aquatic habitats are under review, particularly the marine ones, as these are far too simplistic a view of the marine environment. The categories are numbered to indicate their level in the hierarchy e.g., 1. Forest and 1.1 Boreal Forest.
There is a third level to the classification which is based on the Global Land Cover Characterization (GLCC) developed by the US Geological Survey's (USGS) Earth Resources Observation System (EROS) Data Center, the University of Nebraska-Lincoln (UNL) and the Joint Research Centre of the European Commission (see http://edcdaac.usgs.gov/glcc/glcc.html). This third level is not shown here, because without access to the Species Information Service (SIS) database or the GLCC maps, it is impossible for users to accurately record habitats at this level.
In using this classification, assessors are asked to indicate in which habitats their taxon is found. This is done by means of a simple scoring system:

1 = Suitable (main or preferred habitat/s, habitat/s containing major subpopulations, habitat/s with high population densities)

2 = Moderately suitable (secondary habitat/s, habitat/s containing minor subpopulations, habitat/s with low population densities

3 = Unsuitable (unsuitability expressly known or easily inferred from the ecology of the taxon)
