Conservation status[edit]

This species is classified as Least Concern (LC) on the IUCN Red List of Threatened Species (v3.1, 2001).[4] 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 is unknown. Year assessed: 2007.[5]
