Advena campbellii—Campbell's keeled glass-snail

Conservation significance
Endemic to the Norfolk Island Group.
EPBC Act Listing Status: Critically Endangered
Non-statutory Listing Status: Listed as Extinct on the IUCN Red List (IUCN 2020)
Approved Conservation Advice: 19/12/2008 (DEWHA 2008a).

Description
A small land snail, which usually has a bi-coloured shell with an elevated fawn spire and a black round base. Typical specimen is about 17 mm in diameter and 11 mm high.

Distribution
Campbell's keeled glass-snail (Advena campbellii) was once common on Phillip Island and pre-European fossil records suggest it was once abundant in the Emily Bay-Cemetery Bay area of Norfolk Island (Varman 1991; Neuweger et al. 2001).
Its range contraction and rarity suggested it may be close to extinction, with the species only being recorded in the national park and botanic garden by 2008 (DEWHA 2008).
In surveys undertaken in March 2020 (Hyman & Kohler 2020), Campbell's keeled glass-snail was observed east of Mt Pitt Road and near the national park boundary, both inside and outside the park. Twenty-one living specimens and over 40 empty shells were observed over a 1.5 person-hour search in an area approximately 10 x 60 m. In subsequent surveys in October 2020 and May 2021 the population size had increased, as had the size of the area in which they were found. The current estimated population size is 500 individuals, based on a count of 197 live specimens in May 2022 and 137 live specimens in November 2022, distributed over 1.3 ha and three populations. The distribution is shown in Map 13.

Ecology
Live bearing and the largest of the native land snails.

Habitat
It is known to live under leaf litter, logs and rocks; particularly common under fallen palm fronds (Smith 1992, Hyman & Kohler 2020).

Threats
Major threats include habitat loss, fragmentation and degradation by land clearing and stock grazing, as well as the introduction of feral animals (notably rats) and invasive weeds. Predation by rodents and feral chickens remains a significant threat. Many empty shells found in the 2020 survey showed clear signs of rodent predation, and there were also signs of feral chickens in
