predators and the constraints of limited viable natural habitat; Thai long-tailed
macaque populations in and around temple areas are increasing, while in con-
trast, worldwide populations of long-tailed macaques are in general decreasing
(Eudey,
2008
). The average population size at identified long-tailed macaque
locations is 200 monkeys, but five locations had more than 500 individuals and
eight locations had more than 1,000 individuals. Compared with the popula-
tions reported in each locations by Aggimarnagsee (1992), 20 years ago, the
population has increased two to eight times. At these locations overpopulation
is clearly an issue and human residents have had to take precautions in order to
protect their homes against macaque damage.
Translocation of long-tailed macaques
Translocations have influenced the distribution of long-tailed macaques in
many locations in Thailand. Monkeys at Wat Pa Sila Wiwek, Mukda Han
Province (16° 32' 63” N, 104° 43' 43” E), which were regarded as the north-
ern-most population of typical long-tailed macaques, were reported to have
been translocated from Don Chao Poo Forest Park, Umnajjaroen Province
(15° 36' 36” N, 104° 50' 53” E), approximately 100 km away, several years
