Focal Species


IUCN Red List Status of Focal Species

Of the 72 recorded species in the family, 22 species are extant: 11 are extinct in the wild but surviving in the international breeding program, 9 are critically endangered, and 2 are considered vulnerable. 45 species have gone extinct and data is missing for 5 species.

About the Project

The Partulid Global Species Management Programme’s mission is to preserve and enhance the survival prospects of all endemic tree snail species of the family Partulidae within their natural range of French Polynesia facing extinction after the introduction of the carnivorous Rosey wolfsnail  including the extinct in the wild Tahitian species Partula nodosa.  The intent is to reintroduce the several Partula SSP collection populations currently in the international breeding program in which Woodland Park Zoo participates into secure reserves, or protected areas, on two of the islands of origin for those species.

During this reporting period, introduction of the consolidated populations from the Zoological Society of London will be made into the constructed predator exclusion reserve in Tahiti’s Te Faaiti Natural Park after intensive pre-release health screening in London, exportation to French Polynesia, and completion of an island-based quarantine period.  There will also be introduction of populations into selected and prepared natural habitat in Papehue Valley in Tahitian chestnut trees (called maple trees in Polynesia).  Intensive follow-up monitoring and reporting will be conducted.  The project will aid ongoing public awareness efforts including installation of an interpretive panel at the Partula reserve site in collaboration with the French Polynesian government, as well as wider public engagement opportunities.

Tree Snails at Woodland Park Zoo
Just beyond Bug World, zoo visitors will encounter the Tree Snail Laboratory where they can get a look inside our partulid snail breeding program. You might see zookeepers tending to the snails or catch a glimpse of the newest generation of snail offspring.
