Population Studies of Species with Data Deficient

---

Data Deficient (DD) species have been marked as critically endangered by the IUCN. Still, they are included in the Red list due to inefficient data on their taxonomy, population status, or threats and their impacts. Studying these populations to acquire demographic information for sustainable species management is critical for rapid action toward their conservation. Again, the deficiency in data does not always imply the absence of extensive studies on the organism. Hence, transparent publishing and quick dissemination of knowledge are also highly required.
