Birding Site Guide

The area is 300 km NW of Bangkok and there are several accesses. The first entry is at the headquarters of Huai Kha Khaeng Wildlife Sanctuary, approximately 102 km. from the provincial city along Highway No. 333 (Uthai Thani – Nong Chang). Then take Highway 3438 from Nong Chang – Lan Sak. After turning left at Km. 53-54 and driving along for about 15 km., arriving at the office of Khao Hin Daeng Checkpoint, located on the Huai Thap Salao creek side.

HUAI KHA KHAENG WILDLIFE SANCTUARY VIDEO

The vast expanse of Thung Yai-Huai Kha Khaeng forest is home to a huge variety of flora and fauna, it was one of only two evergreen forest refuges during the driest periods of the Pleistocene glaciations and is on the crossroads of biota from Himalayan, Cambodia-Malaya, Burma and Cochin-china (Sino-Himalayan, Sundaic, Indo-Burmese, and Indo-Chinese). It also covers a large altitudinal range of 200 to 1,800 m. The forests here connect unbroken with the forest of the long border of Burma, the area being prone to malaria and not suitable for farming has preserved it well. Threats however exist with much poaching and illegal logging despite the 200 permanent well equipped rangers in the area.

The sanctuaries are strongholds for birds such as Green Peafowl, Burmese Peacock-Pheasant and Rufous-necked Hornbill. Important mammals include Water Buffalo, Tiger, Sumatran Rhinoceros and Asian Elephant (see lists below for more species and scientific names).

The local varied topography has helped the ethnic people the Karen. This area of steep mountains is in a monsoon zone the waters forming many limestone caves and sinkholes. The highest peak the 1,830 m Thung Yai, is in the far N of the protected area. The main rivers are Kwai Yai and Kwai Noi, which both are tributaries of the Mae Klong River, which runs through Kanchanaburi and Ratchaburi provinces and into the Gulf of Thailand. The mountains affect the monsoon with abundant rains on the W side and the E side having poor rainfall. Forest types include Dry evergreen forest, Mixed deciduous forest, Deciduous dipterocarp forest, Hill evergreen forest and bamboo forest (more on vegetation below).

As well as forest there are the unique huge Thung Yai Grassland (100 square km) which are at around 800 m on shallow topsoil over limestone. The area is covered by both large and small grasslands. The larger areas are named: Thung Yai, Thung Krating, Thung Ruesri and Thung Mongdong. These grasslands dependent on fires to keep out invasion by trees. There are characteristic grassland plants too such as Curcuma Sessilis. Also the palm Phoenix acautiswhich provides fruit and the savannah tree Cycas pectinata, another tree isCycas siamensis.

The dipterocarp forests here are some of the largest in the world, being unique to this part of the world. The types of forest are as follows: in the monsoon climate (W. 1,500mm) and up to 950 m, and where there is a dry season of 3 or 4 months there are dry evergreen forest on deep soils. Drought resistant deciduous species occur on thinner, poorer, more well-drained soils. Deciduous dipterocarp forest is found only in five countries in the world, namely Myanmar, Laos, Cambodia, Vietnam and Thailand.

Dry evergreen forest. The significant species include Dipterocarpus turbinatus,Vatica harmandianaPolyalthia viridisWalsura. trichostemon and Baccaurea ramiflora. They are mixed with deciduous species such as Afzelia xylocarpa andPterocarpus macrocarpus and with ferns, vines and orchids. Bauhinia saccocalyx loses its leaves before flowering prior to the fire season. Dry evergreen forest’s understorey is mainly of Zingiber sp., Alpinia sp. and Boesenbergia sp.

Deciduous dipterocarp forest. The significant species are Dipterocarpacece families, which include Shorea obtuseS. siamensis, and Dipterocarpus obtusifolius. These forest have a fairly open canopy allowing light to the ground and it is prone to annual fires.

Hill evergreen forest. Found at elevations up to 1,000 m. The main species are Castanopsis sp. This is a dense, shady evergreen forest. Sapria himalayana a parasitic plant does not photosynthesis, and takes sap from roots of plants such as Tetrastigma leucostaphyllum.

There is also the bamboo forest in the mixed deciduous forest. It is an excellent food source for much wildlife.
