Details of this species in Hawaii
Source: SPREP, 2000
Arrival Date: c. 1870-1880, possibly as early as 1840
Species Notes for this Location:
The ship rat (Rattus rattus) is adapted especially to wooded gulches, sugar cane fields, and dry, wet, or even extremely wet forests. It is locally common at lower and middle elevations, and is found sparsely distributed at higher altitudes in Hawaii.
Management Notes for this Location:
Predation: Ship rats in Hawaii are thought to be responsible for suppressing seed regeneration of endemic plants, reducing populations of native snails, and significantly limiting breeding success of many native birds (Pitt, 2004). Bonin petrel (see Pterodroma hypoleuca in IUCN Red List of Threatened Species) predation can be reliably attributed to ship rats (Grant et al. 1981).
