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 Bangladesh in the medium-term future.
Data Deficient (DD): A taxon is Data Deficient where there is inadequate information to make a direct, or indirect assessment of its risk of extinction in Bangladesh.
