Long-tailed macaques (Macaca fascicularis) are native to much of
Southeast Asia and have been noted as one of the most geographically
wide-spread and abundant non-human primate species in the world. They have been
deliberately introduced to a variety of small tropical islands, commonly for
Long-tailed macaques are a pest in many introduced areas and the species is
included on the Global Invasive Species Database list of 100 of the
"World's Worst" invaders. In Mauritius, the introduced population has
contributed to the extinction of one parrot and one owl species, and
contributed to the decline of many endangered bird species including pigeons,
parrots, birds of paradise and frogmouths. Small reptiles and large mammals
have also been affected. Modelling indicates that the Tasmanian climate is
unsuitable for this species, however should a population establish, competition
with local possum species could be expected.
The species has a significant impact on agriculture and consumes a wide
variety of crops. Macaques are frequently killed as agricultural pests and some
farmers have stopped planting crops due to damage caused. Long-tailed macaques
are also noted for being a nuisance to humans. They may grab or take human
possessions, threaten people by lunging, biting, following or chasing, and raid
houses, bins and cars. Mobbing behaviour is observed occasionally.
Wild populations of long-tailed macaques are vulnerable to a variety of
diseases including herpes B virus, canine distemper virus and hepatitis E. Some
of these diseases can be fatal to humans.
The species is currently listed as a species of 'least concern' under the
IUCN Red List and is classed as a 'serious' threat under the Vertebrate Pest
Committee's list of exotic animals (Vertebrate Pest Committee, 2007). In
Tasmania, long-tailed macaques are 'controlled animals' under the Tasmanian Nature
Conservation Act 2002.
This risk assessment concludes that long-tailed macaques are a serious
threat to Tasmania and proposes that imports be restricted to those license
holders approved for keeping serious threat species.
