A not-to-be-missed attraction for nature lovers, Hala-Bala is one of Thailands more recent conservation areas. Officially established in 1996, the reserve is located near the Thai-Malaysian border. Covering an area of approximately 433.16 square kilometers, it extends over Sankala Khiri Mountain Range and the deep forests of Hala and Bala Forests that are not connected to each other.
Although they are a part of the same reserve, Hala Forest is in Amphoe Betong in Yala Province and Amphoe Chanae in Narathiwat Province while Bala Forest, the only part that is open to the public, spans Amphoe Waeng and Amphoe Su Khirin in Narathiwat.Highway No. 4062 (Khwam Man Khong Road) goes through Sankala Khiri Mountain Range, making access to the reserve easier.
Wildlife here creates an ecological balance for the area. Many of the animals are on the list of nearly-extinct animals of Thailand. They include the large black gibbon, or Sia Mang, that is totally black in color and nearly double the size of the white-handed gibbon. There is also the agile gibbon that is usually found on Sumatra, Borneo and northern Malaysian jungles and southern Thailand. With luck, visitors may be able to see two of these creatures hanging from a branch. The area also has Thut frogs that are the largest frogs in the country. It is about a foot long and weighs over 5 kilograms. The frogs live in watershed forests on high mountains.
A survey discovered that four types of protected mammals, which are the Sumatran serow, tapir, marbled cat, and Asian two-horned rhinoceros, inhabit the area.The hornbill, a rare bird, is an indicator of the state of the forest. Nonetheless, the reserve has 9 out of 12 species of hornbills in Thailand. These include the wrinkled hornbill, helmeted hornbill (the only kind of hornbill that has a thick upper beak and Indonesian villagers hunt it to get the beak to carve into ornaments like ivory), Oriental pied hornbill, great pied hornbill, white-crowned hornbill, bushy-crested hornbill, Malayan rhinoceros hornbill, black hornbill, and wreathed hornbill.
Visitors wishing to enter the area for nature study must write in advance to the reserve at P.O. Box 3, Amphoe Waeng, Narathiwat 96120 or the Wildlife Reserve Department of the Natural Resources Conservation Office, Royal Forest Department, Bangkok. As the reserve is a sensitive area, visitors are not permitted to stay overnight. The best time to study nature here is from late February to September, when there is little rain.
