What is a data deficient species?
What is a data deficient species?
Under these categories, the IUCN defines “data deficient” species as ones where “there is inadequate information to make a direct, or indirect, assessment of its risk of extinction based on its distribution and/or population status” (IUCN, 2001).
How many data deficient species are there?
However, of the eight Data Deficient species, we suggest that significant population reduction is likely for at least three of these based on (a) their geographic range and habitat overlapping with areas of intense and increasing fishing pressure lacking adequate management; and, (b) the threatened status of co- …
What are the 7 categories of the IUCN Red List?
The IUCN Red List Categories and Criteria are intended to be an easily and widely understood system for classifying species at high risk of global extinction….
- Data Deficient (DD)
- Least Concern (LC)
- Near Threatened (NT)
- Vulnerable (VU)
- Endangered (EN)
- Critically Endangered (CR)
- Extinct In The Wild (EW)
- Extinct (EX)
Which animal is critically endangered?
Species Directory
| Common name | Scientific name | Conservation status ↓ |
|---|---|---|
| Hawksbill Turtle | Eretmochelys imbricata | Critically Endangered |
| Javan Rhino | Rhinoceros sondaicus | Critically Endangered |
| Orangutan | Pongo abelii, Pongo pygmaeus | Critically Endangered |
| Saola | Pseudoryx nghetinhensis | Critically Endangered |
Is Vulnerable Endangered?
What does Endangered mean? Critically Endangered (CR): A species facing an extremely high risk of extinction in the wild. Endangered (EN): A species considered to be facing a very high risk of extinction in the wild. Vulnerable (VU): A species considered to be facing a high risk of extinction in the wild.
What is the conservation status of the animal?
The conservation status of a group of organisms (for instance, a species) indicates whether the group still exists and how likely the group is to become extinct in the near future.

What is datadata deficient?
Data Deficient (DD) is a category applied by the IUCN Red List, other agencies, and individuals to a species when the available information is not sufficient for a proper assessment of conservation status to be made.
How can we predict the IUCN status of data deficient species?
Two more-sophisticated approaches hold promise for predicting the IUCN status of Data Deficient species but require considerably more data. The “simplest” requires a phylogeny and distribution maps of all species, including the DD species.
How many data deficient mammals are in the IUCN threat categories?
Data Deficient species that are related to and geographically near Critically Endangered species are also likely to be in the same IUCN category. Using this approach, scientists found that 331 of the 483 Data Deficient mammals might be in one of the IUCN threat categories; AUC was 0.9 and R2 = 0.4 ( Jetz and Freckleton, 2015 ).
What does it mean when a species has not been extensively studied?
This does not necessarily indicate that the species has not been extensively studied; but it does indicate that little or no information is available on the abundance and distribution of the species.
