    地點註解：
    影響：
    威脅瀕危物種: Black rat, Rattus rattus are likely to be preventing some seabirds from successfully recolonising Tristan, and also to be major predators of the island's landbirds, notably the 'Near Threatened (NT)' rare Tristan thrush (see Nesocichla eremita> in IUCN Red List of Threatened Species) (Hilton, 2004 in Varnham, 2006).
    農業: Black rats, Rattus rattus are important agricultural and food storage pests on Tristan (Hilton, 2004 in Varnham, 2006).
    降低本地生物多樣性: Massive reductions of storm petrels (Pelagodroma marina) and Prions (Pachyptila forsteri) can be attributed to predation by cats (now eliminated) and rats.
