Accordingly, two buff-cheeked gibbons (Nomascus annamensis), one otter, two northern pig-tailed macaques (macaca leonina) and one red-faced monkey were released back into the wild. Among them, one pig-tailed macaque was released for the second time. It was keptin captivity since very young, and has lost most of its wild instincts.
The centre said these animals were handed over by local people and werecared for by the Center in a semi-wild environment forthe past several months. After their release, the centre will continue to monitor them.
Buff-cheeked gibbon, pig-tailed macaque,red-faced monkey, and otter have been included in the Vietnam Red Book 2000and the list of species that need protection by the forestry sector./.
