Ecology Hahajima is of considerable interest to malacologists because of its endemic land snail fauna, including the eponymous Lamprocystis hahajimana. Due to the widespread presence of invasive species including goats (which destroy habitat) and rodents, flatworms and the rosy wolfsnail (which eat the native snails), it was feared that many of the endemics had become extinct. But most if not all of the endemic land snail species seem to persist on the remote Higashizaki peninsula on the eastern coast. This is a quite pristine expanse of ground, scenic but very hard to reach (one has to climb Mt. Chibusa before descending to the peninsula). It consists of sheer seacliffs surrounding a plateau with Chinese fan palm (Livistona chinensis), pandanus and broadleaf (e.g. Persea kobu, a wild avocado) forest, and appears to be untouched by invasive species at present. It has been proposed that access to the area should be monitored, so that visitors will not inadvertently contribute to destroying this unique area. Snails All of these snails are endemic at least to the Bonin Islands. Boninena callistoderma - Endangered, now restricted to Hahajima and nearby Anejima Gastrocopta boninensis - Vulnerable Hirasea acutissima - Endangered (believed extinct, rediscovered 2003), endemic to Hahajima Lamellidea biplicata - Vulnerable Lamprocystis hahajimana - Endangered Mandarina hahajimana - Data deficient, possibly a new taxon Mandarina polita - Data deficient Ogasawarana yoshiwarana - Critically endangered (believed extinct, rediscovered 2003), endemic to Hahajima Ogasawarana arata - Data deficient Paludinella minima - Data deficient Vertigo dedecora - Vulnerable Tornatellides tryoni Birds Among birds, the Bonin white-eye (Apalopteron familiare), a gaudy-colored passerine, seems to occur nowhere else anymore than on Hahajima. The extinct Bonin grosbeak (Chaunoproctus ferreorostris) is sometimes said to have occurred in the Hahajima Group (though not on Haha-jima itself), but this seems not to be true. Columba janthina nitens, the Bonin subspecies of the Japanese wood-pigeon, used to occur on Haha-jima. While it is not precisely known when it vanished from this island, the taxon apparently became completely extinct during the 1980s, but was rediscovered in 1998. The island has been recognised as an Important Bird Area (IBA) by BirdLife International.
