Conservation status
editThis species is classified as least concern on the IUCN Red List of Threatened Species (v3.1, 2001).[5] Species are listed as such due to their wide distribution, presumed large population, or because it is unlikely to be declining fast enough to qualify for listing in a more threatened category. The population trend was stable when assessed in 2007.[6]
