Rediscovered Species and Subspecies

Rediscovered Yunnan Box TurtleExtinction of organisms is difficult to prove, even in well-studied groups such as mammals (Fisher & Blomberg, 2010). Organisms that haven’t been sighted for a long time and are considered possibly extinct, are regularly rediscovered (Fisher & Blomberg, 2010).

Australian biologists Diana O. Fisher and Simon P. Blomberg conclude in their paper published in 2010 that “[mammal] species affected by habitat loss were much more likely to be misclassified as extinct or to remain missing than those affected by introduced predators and diseases, or overkill, unless they had very restricted distributions” (Fisher & Blomberg, 2010).

It is most likely that the highest rates of rediscovery will come from searching for species that have gone missing during the 20th century and have relatively large ranges threatened by habitat loss, rather than from additional effort focused on charismatic missing species. (Fisher & Blomberg, 2010).

NOTE: The lists with rediscovered species and subspecies presented here are incomplete and will regularly be updated with new entries. Do you know a species or subspecies that should be included? Please contact us if you have more information.

 

Species

The subjoined table shows you some of the rediscovered species in an incomplete list. Three rediscovered species have been removed from the subjoined list: the Christmas Island Shrew (Crocidura trichura). This species was last sighted in 1900 and rediscovered in 1985 (Fisher & Blomberg, 2010). However, recent surveys were not able to find it. The Vanikoro Flying Fox (Pteropus tuberculatus) was last collected in 1828 until it was rediscovered in 1927. However, it has not been recorded since and Vanikolo was extensively logged in the 1950s and 1960s. Surveys in the early 1990s did not detect this species and it might possibly be extinct. Therefore theyse two species have been moved to the list of missing species and subspecies that are possibly extinct. The now extinct Desert Rat Kangaroo (Caloprymnus campestris) was first believed extinct in 1841, but rediscovered in 1931 (Fisher & Blomberg 2010). Sadly it became extinct 'again' in 1935 (Turvey 2009; IUCN 2011). Unconfirmed sightings in Queensland are reported in 1956-1957 and 1974-1975 (Carr & Robinson 1997; IUCN 2011)

Subspecies

The subjoined table shows you some of the rediscovered subspecies in an incomplete list. Although it was not completely extinct and surviving in captivity, the partulid snail Partula taeniata elongata has been rediscovered in the wild on the island of Moorea (French Polynesia) in 2003 (Coote, 2007).

The Sixth Extinction Database (TSED)

The Sixth Extinction has created a database (TSED 1.0) with currently all known recent mammal extinctions, possible extinctions, extinctions in the wild, rediscoveries, and more. Later versions of this database will include extinctions from all animal and plant groups. The database is free to download in Excel and OpenDocument formats.
