    Australia English 
    棲地改變: The Baw Baw frog (Philoria frosti) is listed as 'Critically Endangered (CR) in the IUCN Red List of Threatened Species. Native to Australia it is restricted to the Baw Baw plateau east of Melbourne. There is a deficiency of information in relation to demography and population dynamics of this species. Climate change impacts, pathogens such as the chytrid fungus (Batrachochytrium dendrobatidis); Willow (Salix cinerea), cattle (Bos taurus), rabbits (Oryctolagus cuniculus), Sambar deer (Rusa unicolor), foxes (Vulpes vulpes), dogs (Canis lupus) and cats (Felis catus) have been identified as invasive species that might be impacting the species (Hero et al 2004).

    競爭: Native to Australia, the Night Parrot (Pezoporus occidentalis) is listed as Critically Endangered (CR) in the IUCN Red List of Threatened Species. Predation by foxes (Vulpes vulpes) and feral cats (Felis catus); competition for food and habitat degradation by introduced rabbits and reduced availability of water due to over-use by introduced camels (Camelus dromedarius) are some of the potential threats to the survival of this species. Decline in populations have been recorded in some areas coinciding with the arrival of feral cats (BirdLife International 2009).

    競爭: The Australian native Princess parrot (Polytelis alexandrae) is listed as Near Threatened (NT) in the IUCN Red List of Threatened Species. Habitat degradation due to altered fire regimes; herbivory and competition by introduced herbivores, rabbits (Oryctolagus cuniculus); sheep (Ovis aries) and camels (Camelus dromedarius); and predation by cats (Felis catus) and red foxes (Vulpes vulpes) are some of the threats to this species (BirdLife International 2008)

    Macquarie Is. (sub-Antarctic) (Australia) English 
    棲地改變: In Sandy Bay Healthy green tussock vegetation is being replaced by dead brown stumps due to rabbit grazing (Tasmania National Parks Association Inc. 2006).

    物理干擾: Macquarie Island’s largest king penguin (see Aptenodytes patagonicus in IUCN Red List of Threatened Species) colony, found at Lusitania Bay, was threatened by a landslide which occurred in September 2006 and which was thought to be due to a combination of heavy rainfall and rabbit grazing which increased the instability of the land. The landslide buried some penguins alive and destroyed part of the colonies habitat (Tasmania National Parks Association Inc. 2006).

    生態系統變化: Rabbits, rats and mice are causing extensive impacts on the biodiversity and landscape of the Macquarie Island Nature Reserve (Parks and Wildlife Service 2006). Rabbits are key drivers of ecosystem change. The drive at least two key threatening processes on Macquarie Island; one is their impact on vegetation (tall tussock grassland and herbfields), the second is their alteration of valuable seabird habitats via increasing soil instability and erosion processes (Parks and Wildlife Service 2006). Rabbits are known for their ability to heavily graze vegetation, destroyed some tall tussock grassland areas and converting them to short grassland or mire (Copson 1984, Scott 1988, in Parks and Wildlife Service 2006). Some plant species, such as Pleurophyllum hookeri and Stilbocarpa polaris, are so heavily grazed by rabbits that they have become locally extinct from some sites on the island (Parks and Wildlife Service 2006).
    It is thought that habitat alteration by rabbits, as well as predation by skuas and introduced cats, wekas and rats, have greatly reduced or even eliminated populations of some of the smaller species of prion and petrel which once bred in the reserve (Brothers 1984, Brothers and Copson 1988, in Parks and Wildlife Service 2006).
    Soil stability is a key environmental variable in the Macquarie Island Nature Reserve which is affected partly by rabbit grazing, and also by continual winds, seismic activity, freezing and thawing and constant precipitation (Parks and Wildlife Service 2006).

    經濟 /民生: Loss of tourism value. A landslide believed to be caused by heavy rabbit grazing in September 2006 adjacent to Sandy Bay staircase forced the closure of the staircase, boardwalk and Royal penguin viewing platform (key visitor infrastructure) (Tasmania National Parks Association Inc. 2006).
    Norfolk Island English 
    吃草: The average rate of extinction of plant species between 1830 and 1977 was approximately one species every 10 years (Fullager 1978).

    物理干擾: Extensive soil erosion frequently follows the loss of plant cover that results from browsing by rabbits.

    與其他入侵物種相互作用: Rabbits can also become additional food for animals such as cats, enabling these predators to increase their numbers and thus eat more native animals, including lizards and birds. This is an example of a flow-on effect, where the introduction of one problem animal results in an increase of another invasive species already established.
    Ascension Is. (Saint Helena) English 
    威脅瀕危物種: Rabbits are affecting re-establishment of the 'Critically Endangered (CR)' endemic Ascension Spurge (see Euphorbia origanoides). Rabbits have affected attempts at re-establishment of this plant by grazing and digging at the base of plants, possibly to feed on the roots. Similarly rabbits are affecting establishment of new colonies of the 'Near Threatened (NT)' fern (see Marattia purpurascens).

    降低本地生物多樣性: There are suggestions that rabbits may be affecting the ability of smaller sea bird species to recolonise the island (Pickup, 1999 in Varnham, 2006).
    Saint Helena English 
    與其他入侵物種相互作用: Rabbits have important predator-prey interactions with other invasive species on St Helena such as feral cats and rats. High rabbit numbers help maintain high predator numbers. Rabbit numbers are particularly high on two of the best habitats of the 'Critically Endangered (CR)' endemic wirebird (see Charadrius sanctaehelenae) on St Helena . As a result feral cats, which predate wirebirds, are also found in high numbers (Bell & Boyle 2008). Control of rabbits may result in prey switching of feral cats and rats to native species.

    農業: Rabbits are an important agricultural and horticultural pest on St Helena. Farmers have reported almost total loss of crops by rabbit browsing (Bell & Boyle, 2008) and horticultural production at Longwood and Sandy Bay has suffered up to 100% losses of young plants. Rabbits also graze pasture which reduces food for sheep and other livestock (Miller, 2008).

    降低本地生物多樣性: Rabbits threaten the five endemic plant species on St Helena through browsing, and are particularly damaging to young native plants growing in drier coastal zones (Miller 2008).
    La Palma Is. (Spain) English 
    捕食: The La Palma endemic (Lactuca palmensis) is listed as Least Concern (LC) in the IUCN Red List of Threatened Species. Threats to this species include predation by feral goats (Capra hircus), rabbits and the introduced game species aoudad (Ammotragus lervia) leading to population declines and habitat destruction (Guerra 2011)

    捕食: The Vulnerable (VU) Retamón (Genista benehoavensis) is endemic to the island of La Palma, Canary Islands, Spain. The major threat to the survival of this species is predation by goats (Capra hircus) ; rabbits and the introduced aoudad (Ammotragus lervia) leading to habitat destruction and decline in populations (Alamo et al 2011)
    Tenerife (Spain) English 
    捕食: Native to the Canary Islands and found on La Palma and Tenerife, Garbancera canaria (Cicer canariense) is listed as Endangered (EN) in the IUCN Red List of Threatened Species. The main threats to the survival of this species is the threat posed by introduced herbivores such as rabbits (Oryctolagus cuniculus); goats (Capra hircus); sheep (Ovis aries); and the game species Ovis musimom and aoudad (Ammotragus lervia) (Guerra & Betancort 2011).
    Canarias (Spain) English 
    捕食: Native to the Canary Islands, Spain (Bencomia exstipulata) is listed as Vulnerable (VU) in the IUCN Red List of Threatened Species. Major threats include browzing and herbivory by rabbits. Herbivory by introduced game species Ovis musimom, and aoudad (Ammotragus lervia); and rats are an additional threat (Baudet et al 2011)

    Laysan Is. (United States (USA)) English 
    吃草: Between 1903 and 1923 (when they were eradicated) rabbits apparently eliminated 26 species of plants, a rate of loss exceeding one species per year (Christophersen and Caum 1931). A subsequent visit by Lamoureaux (1963) indicates that not all of these species became extinct on Laysan Island; presumably regeneration from seed had been possible. The vegetation was severely damaged. In 1923 the island was ‘a barren waste of sand with a few stunted trees’, only four of 26 plant species could be found, and three land birds had died out.

    棲地改變: The Laysan crake (Porzana palmeri) was found on Laysan Island, Hawai'i, USA, from where it became extinct between 1923 and 1936. Habitat destruction by rabbits (Oryctolagus cuniculus) and guinea pigs (Cavia porcellus) introduced by guano diggers, was reported to be the major cause (BirdLife International 2008)
