Norfolk Island’s largest native land snail Advena campbellii is one of the three Critically Endangered species
Land snails are underappreciated but play essential roles in recycling nutrients in soils and as food for many animals. Around 60 unique land snail species call Norfolk and Phillip Islands home. They come in a remarkable variety of shapes and colours but are facing threats from predators like rats and flatworms, and habitat loss. Currently, two species have become extinct while three species are Critically Endangered. Following the footsteps of Australian Museum researchers, PhD candidate Junn Kitt Foon of Western Sydney University is undertaking a three-year project to study:
(1) How are the last populations of these threatened snails genetically connected to each other?
(2) What habitats are best for native snails?
(3) How much are these snails affected by non-native predators?
(4) How might climate change affect these snails?
Answering these questions will hopefully help secure the long-term survival of these unique Norfolk and Phillip Island species.
