Baan Pang Chum Pee

Finding a suitable location in Chiang Mai, that assured the sustainability of a long term Gibbon Release programme was a considerable challenge, not least  because the trustees were determined that the local community had to be responsible for protecting the Gibbons if the project stood any chance of success.

After several years of research, the village of Baan Chum Pee was discovered.  Chum Pee Community Forest (PCF) is in the Mae On national reserve forest, (under the National Forest Reserve act B.E. 2507 (1964))
nestled in the folds of Doi Saket Mountain, approximately 40 KM East of Chiang Mai.

The village encompasses a  total area of approximately 12,091 Rai (1,934 ha), consisting of no-hunting conservation zone 5,091 Rai (814 ha) and sustainable utilization zone 7,000 Rai (1,120 ha). There are several streams and waterfalls with some wild mammals such as Wild boar (Sus scrofa), Common Barking deer (Muntiacus muntjak), Rhesus macaque (Macaca mulatta), Asiatic Black bear (Selenarctos thibetanus), Malayan pangolin (Manis javanica), Common Palm civet (Paradoxurus hermaphrodites) and Large Bamboo rat (Rhizomys sumatrensis). The natural predators of the gibbon in PCF are potentially the Crested Serpent-eagle (Spilornis cheela), Burmese python (Python molurus bivittatus) and some large wild cats.

The most exciting and significant fact about Baan Chum Pee is the villager’s commitment to rehabilitating the Gibbons.  The headman tells of his grandparents often describing the Gibbon song to him, and after many years of exploiting his forest, he and the other villagers have realised that their future lies in preservation and conservation, not exploitation.

The long term future of the project in Chiang Mai is dependent on this type of cooperation.  The other major goal for the project will be educating the local people, especially the next generation about the Gibbon project and how they can help.

With the help of the villagers, extensive ground and aerial surveys were conducted to find the best area to place the Gibbons. The most suitable habitat is at Huay Pong Lung valley. This site was firstly selected because it was a dry evergreen forest, where there is water supply all the year and easily accessed by the following and observation team. There was high abundance of food trees, which mostly were Ficus species and at least 22 different species of plants (in 16 families). All species are shown in table 1, with the growth types to which they belong, the parts of the plant which were eaten and local Thai name.

Huay Pong Lung valley site is large enough to release 3 family groups.  PCF is connected to Mae On national reserve forest. This habitat could be much larger than Khao Phra Thaew forest, Phuket and can sustain more than 60 family groups.As part of many initiatives they were very eager to participate in the re-introduction of Gibbons to the forest.
