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.This conservation category is one of nine IUCN threat assessment categories for species to indicate their risk of global extinction. The categories range from 'extinct' (EX) at one end of the spectrum, to 'least concern' (LC) at the other. The categories 'data deficient' and 'not evaluated' (NE) are not on the spectrum, because they indicate species that have not been reviewed enough to assign to a category.The category of 'not evaluated' does not indicate that a species is not at risk of extinction, but simply that the species has not yet been studied for any risk to be quantified and published. The IUCN advises that species categorised as 'not evaluated' "...should not be treated as if they were non-threatened. It may be appropriate ... to give them the same degree of attention as threatened taxa, at least until their status can be assessed.
