Études de cas sur la gestion
Bora Bora (Pora-Pora) Is. (Society Islands)
The only native snail on Bora Bora of the Partula genus probably became extinct soon after 1986, the year that Euglandina rosea was introduced. The most recent survey was in 1991.
Huahine Is. (Society Islands)
All three native snail species of the Partula genus on Huahine were extinct in the wild by 1997, but 2 species survive in captivity. The most recent survey was in 2000.
Moorea Is. (Society Islands)
It was believed that all seven native snail species of the Partula genus on Moorea were extinct by 1987. However, a small population of one species was located in 2001 by Jean-Yves Meyer of the French Polynesian Research Department. Five species survive in captivity. Attempts are being made through the International Union for the Conservation of Nature (IUCN) for the captive breeding of those stocks that remain in the laboratory (Murray et al 1988)
Raiatea Is. (Society Islands)
The unexpected discovery of these two surviving montane populations raises the possibility of preserving some fraction of Raiatea’s endemic tree snail diversity in the wild (Lee et al. 2008).
Partulidae are clearly a highly threatened family of invertebrates and in need of the most intense conservation focus.

Résumé: This compilation of information sources can be sorted on keywords for example: Baits & Lures, Non Target Species, Eradication, Monitoring, Risk Assessment, Weeds, Herbicides etc. This compilation is at present in Excel format, this will be web-enabled as a searchable database shortly. This version of the database has been developed by the IUCN SSC ISSG as part of an Overseas Territories Environmental Programme funded project XOT603 in partnership with the Cayman Islands Government - Department of Environment. The compilation is a work under progress, the ISSG will manage, maintain and enhance the database with current and newly published information, reports, journal articles etc.
