An eradication attempt is to take place.
Other: Although Dirk Hartog Island remains a pastoral station and has also supported large populations of goats (Burbidge and George 1978, in Dickman 1996), strong comparative evidence implicates cats in the wave of extinctions. Bernier and Dorre Islands, to the north of Dirk Hartog, do not have cats and have retained their original faunas almost intact. Both Bernier and Dorre have been subject, to intermittent human occupation and sheep grazing; goats were also present on Bernier for nearly 90 years and caused considerable damage to the island's vegetation before their eradication in the mid-1980s (Morris, 1989, in Dickman 1996).
Reduction in native biodiversity: Cats have been implicated in the loss of several small and medium-sized mammals from Dirk Hartog Island, Western Australia. Burbidge & George (1978) report local knowledge that the `wallabies' (see Lagostrophus fasciatus in the IUCN Red List of Threatened Species) and the burrowing bettong (see Bettongia lesueur in the IUCN Red List of Threatened Species) became extinct in the 1920s. However, as some doubt has been cast recently on the former presence of L. fasciatus on Dirk Hartog (Baynes 1990, in Dickman 1996) the local reports may refer to B. lesueur alone. The following species also went extinct on the island probably in part due to predation by feral cats: the mulgara (see Dasycercus cristicauda in the IUCN Red List of Threatened Species), the Western quoll (see Dasyurus geoffroii in the IUCN Red List of Threatened Species), Sminthopsis dolichura (the little long-tailed dunnart), the Western barred bandicoot (see Perameles bougainville in the IUCN Red List of Threatened Species), Pseudomys albocinereus (the ash-grey mouse) and Pseudomys hermannsburgensis (the sandy inland mouse).
