来源： Hilton, 2004 in Varnham, 2006 此地点的物种说明：
Black rat, Rattus rattus is found to occur mainly in forests though there may be some present in agricultural and residential areas (Hilton, 2004 in Varnham, 2006). 此地点的管理信息：
Experimental rat control is ongoing at a small sample of Montserrat oriole nesting sites in the Centre Hills. There are plans to revive rat control in agricultural areas (Hilton, 2004 in Varnham, 2006). 影响：
传播疾病: Rats are also considered to be major agricultural and public health pests (Hilton, 2004 in Varnham, 2006).
农业: Rats are also considered to be major agricultural and public health pests (Hilton, 2004 in Varnham, 2006).
威胁濒危物种: Rattus rattus is known to predate nests of the 'Vulnerable (VU)' forest thrush (seee Cichlherminia lherminieri in IUCN Red List of Threatened Species) and the 'Critically Endangered (CR)' endemic Montserrat oriole (see Icterus oberi in IUCN Red List of Threatened Species). Rat predation is a major factor in the decline of the oriole in recent years (Hilton, 2004 in Varnham, 2006).
R. rattus are known to attack and kill mountain chicken the near-endemic 'Critically Endangered (CR)' (see Leptodactylus fallax in IUCN Red List of Threatened Species) though the population impact is not known (Hilton, 2004 in Varnham, 2006).
生态系统变化: Rattus rattus can affect forest ecology through predation of seeds, fruits, flowers, seedlings and invertebrates (Hilton, 2004 in Varnham, 2006).
降低本地生物多样性: Rattus rattus is likely to be significant predator of other birds and herptiles (some endemic). 最后修改 ： 17/06/2008 9:57:30 a.m.
