DATA DEFICIENT (DD) -
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 is lacking.
