Notes:
1 Species list adapted from BirdLife International (2000). The list covers species and populations that breed and migrate within the Asia-Pacific region. In addition, it includes three "globally threatened" species Corn Crake , Slender-billed Curlew and Great Snipe that breed within the region and migrate outside.
2 Categories of threat follow BirdLife International (2000). Information provided below is abstracted from the publication which provides detailed information on the criteria used for the classification.
CRITICALLY ENDANGERED (CR). A taxon is Critically Endangered when it is facing an extremely high risk of extinction in the wild in the immediate future, as defined in any of the criteria.
ENDANGERED (EN). A taxon is Endangered when it is not Critically Endangered but is facing a very high risk of extinction in the wild in the medium-term future, as defined in any of the criteria.
VULNERABLE (VU). A taxon is Vulnerable when it is not Critically Endangered or Endangered but is facing a high risk of extinction in the wild in the medium-term future, as defined in any of the criteria.
LOWER RISK (LR). A taxon is Lower Risk when it has been evaluated, does not satisfy the criteria for any of the categories Critically Endangered, Endangered or Vulnerable. Taxa included in the Lower Risk category can be separated into three subcategories:
- Conservation Dependent (CD). Taxa which are the focus of a continuing taxon-specific or habitat-specific conservation programme targeted towards the taxon in question, the cessation of this conservation programme would result in the taxon qualifying for one the threatened categories above within a period of five years.
- Near Threatened (nt). Taxa which do not qualify for Conservation Dependent, but which are close to qualifying for Vulnerable.
- Least Concern (lc). Taxa which do not qualify for Conservation Dependent or Near Threatened.
3 Status of species follows Perennou et al. (1994): M - Migratory species, MR - migratory species with resident populations
4 Populations estimates are based on Perennou et al. (1994) and Rose and Scott (1997).
5 The population estimated only refers to the population in the Asia-Pacific region for a species which has an extended range.
6 Updated population estimates base on BirdLife International (2000).
