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).
What does the term data deficient mean?
adjective Biology, Ecology. (of a plant or animal species) lacking a properly assessed conservation status due to insufficient information on population and distribution, as categorized by the IUCN Red List: We are tracking the populations of data deficient fishes and mollusks.
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 is data deficiency in research?
Data deficient. A data deficient species is one which has been categorised by the International Union for Conservation of Nature as with no sufficient information for a proper assessment of conservation status to be made.
What is the meaning of not evaluated?
A not evaluated (NE) species is one which has been categorized under the IUCN Red List of threatened species as not yet having been assessed by the International Union for Conservation of Nature.
What is the meaning of least concern?
(of a plant or animal species) assessed to be thriving, with a distribution or population status that is neither threatened nor near threatened, as categorized by the IUCN Red List: Among the least concern birds on our favorite watches are the sandhill cranes and the pied-billed grebes. Abbreviation: LC.
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 not evaluated species?
What means evaluative?
To be evaluative is to consider or judge something carefully. Find yourself deeply contemplating whether the new polka dot paint job really brightened up your kitchen? Then you are looking at those dots with an evaluative eye. At the core of the word evaluative is value.
What do we do with data-deficient species?
Typically, data-deficient species need investment in targeted research or survey to fill those knowledge gaps and determine the best approach to on-ground management. Examples in this category include small flower grevillea and the little whip snake. Research or surveys of these species are a priority for the Saving our Species program.
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.
