an Entity references as follows:
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.
