Details of this species in Falkland Islands (Malvinas) (sub-Antarctic)
Source: Douse, A., pers.comm., 2004 in Varnham, 2006
Arrival Date: 1830s but possibly earlier
Species Notes for this Location:
Felis catus, domestic cats were deliberate introduction. Feral cats are found mainly around coasts and near settlements. They are present on most but not all inhabited offshore islands. Found in 73, 10km squares. Feral cats are unlikely to expand their range & distribution.
Management Notes for this Location:
There has been some local action to reduce or eliminate cats. The possibility of selective eradication at some localities needs to be considered. It is recommended to reduce cat population in or near sensitive sites.
Reduction in native biodiversity: Felis catus have major impact on the distribution of ground nesting birds.
Threat to endangered species: Felis catus may have lead to much reduced populations of some vulnerable species. Breeding of the Tussock bird (Cinclodes antarcticus antarcticus) and the 'Vulnerable (VU)' Cobb's wren (see Troglodytes cobbi in IUCN Red List of Threatened Species) have become restricted to cat- and rat-free islands due to predatory impacts (in Atkinson, 1985 in Varnham, 2006). Feral cats and rats are likely to have decimated entire populations of Cobb's wren on some small islands (BirdLife International 2006).
