Ubud Monkey Forest is dwelt by more than 200 monkeys belonging to long tailed monkey group in Latin language called macaques or Macaca fascicularis that has the wide distribution area. Among the number of monkeys, there are around 23 adult male monkeys, 79 adult female and more than 98 were children. All monkeys in the forest are consisted of 3 groups that occupying a certain area and use the certain place including the certain time as well. When two groups are existing in one place at the same time, hence the fight is difficult to be avoided. Those monkeys are believed by the local societies as the holy monkeys that keep the temple and forest from the bad influences.
The forest has been populated by monkeys in greater numbers than an environment undisturbed by humans would allow for a number of years, with the population density now (2013) higher than ever. The visitor will notice the interesting phenomenon of numerous obese monkeys, a testament to the almost unbounded food supply the huge number of tourists entering in and near the forest provide. Tourists are bitten by monkeys daily and numerous of these attacks can be can be found by a key word searches on YouTube. The monkeys - crab eating macaques - will invariably approach human visitors in a large group and then grab any bags containing food. They may also grab bags not containing food. If the demanded food is readily provided the monkeys will usually not, although occasionally will, bite the human owner. If the demanded food is not provided quickly enough, one or more of the monkeys will certainly bite the human owner. Numerous bites occur because humans are not quick enough in producing a desired food item. Given that tourists don't enter and travel the monkey forest armed and ready to fight relatively small monkeys, and that dogs are not allowed inside, the monkeys have none of the normal environmental competitors to keep them in check. They have also lost the fear of humans normal to almost all animals.
