It's believed there are about 30,000 mongooses in [[Okinawa prefecture]] today (a figure which does not include those in the [[Amami Islands]]).<ref name=yamatomizu>Gallery labels, Yama to mizu seikatsu hakubutsukan, Higashi Village, Okinawa.[https://www.flickr.com/photos/toranosuke/49599950422/sizes/l/]</ref> |
− | Indian mongooses were intentionally introduced into [[Okinawa prefecture]] in [[1910]], with the intention of combating the problems of vermin such as rats and ''[[habu]]'' (Ryukyuan pit viper). However, the mongooses proliferated without making a significant impact upon rat or snake populations - as in Hawaii and elsewhere, the key problem is that mongooses are diurnal, and sleep during the night, when they might otherwise encounter nocturnal rats or snakes. Instead, mongooses have had a severely negative impact upon populations of many native species, including ''[[Yanbaru kuina]]'' (flightless birds of northern Okinawa Island) and Amami rabbits, both of which are now endangered. | + | Indian mongooses were intentionally introduced into Okinawa prefecture in [[1910]], with the intention of combating the problems of vermin such as rats and ''[[habu]]'' (Ryukyuan pit viper).
