A rare species is a group of
Rarity rests on a specific species being represented by a small number of organisms worldwide, usually fewer than 10,000. However, a species having a very narrow
Rare species are species with small populations. Many will move into the endangered or vulnerable category if the negative factors affecting them continue to operate. Well-known examples of rare species - because these are large terrestrial animals - include the
They are not endangered yet, but classified as "at risk", although the frontier between these categories is increasingly difficult to draw given the general paucity of data on rare species. This is especially the case in the world Ocean where many 'rare' species not seen for decades may well have gone extinct unnoticed, if they are not already on the verge of extinction like the mexican Vaquita.
A species may be endangered or vulnerable, but not considered rare if it has a large, dispersed population.
A rare plant's legal status can be observed through the USDA's Plants Database.
