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.  Where feasible, the intent is to reintroduce the 11 species that currently exist only 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.  Regular monitoring of remnant populations and surveys to maintain up-to-date information on the species is the focus of the project.

The most immediate goal for the project is the re-establishment of 4-6 of the species from the breeding program into secure reserves, or protected areas, containing natural habitat on at two of the islands of origin of those species.  A secondary goal is the establishment of a parallel research project into the ecology and control of the Rosey wolfsnail.

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.
