Notes:

1. Species list adapted from Collar et al. (1994) and Perennou et al. (1994). The list covers species and populations that breed and migrate within the Asia-Pacific region. In addition, it includes two "globally threatened" species Crex crex and Numenius tenuirostris that breed within the region and migrate outside.

2. Categories of threat follow IUCN/Species Survival Commission (1994). Information provided below is abstracted from the publication which provides detailed information on the criteria used for the classification.

  1. 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.
  2. Near Threatened (nt). Taxa which do not qualify for Conservation Dependent, but which are close to qualifying for Vulnerable.
  3. Least Concern (lc). Taxa which do not qualify for Conservation Dependent or Near Threatened.

DATA DEFICIENT (DD). A taxon is Data Deficient when there is inadequate information to make a direct, or indirect, assessment of its risk of extinction based on its distribution and/or population status. A taxon in this category may be well studied, and its biology well known, but appropriate data on abundance and/or distribution are lacking. DD is therefore not a category of threat or Lower Risk. Listing of taxa in this category indicates that more information is required and acknowledges the possibility that future research will show that threatened classification is appropriate. It is important to make positive use of whatever data are available. In many cases great care should be exercised in choosing between DD and threatened status. If the range of a taxon is suspected to be relatively circumscribed, if a considerable period of time has elapsed since the last record of a taxon, threatened status may be well justified.

NOT EVALUATED (NE). A taxon is Not Evaluated when it has not yet been assessed against the criteria.

3. Status of species follows Anon (1993): M - Migratory species, MR - migratory species with resident populations


4. Populations estimates are adapted from Perennou et al. (1994) and Rose and Scott (1994). Global (G) population estimate is provided for species that are restricted to the Asia-Pacific region. For species that have an extended distribution beyond the Asia-Pacific region, a regional (R) population estimate is provided. ? indicates lack of information. Additional details of population sizes of populations of species will be covered in species/species group action plans.

5. Population estimate from W. Larned, U.S. Fish and Wildlife Service (in litt. 1996).
