Pang Sida National Park

  • Pang Sida National Park comprises 844 square kilometers in Mueang, Wathana Nakhon os Sa Kaoe and Na Di of Prachin Buri Province in Northeast Thailand.
  • Pang Sida National Park is part of The Dong Phayayen-Khao Yai Forest Complex declared a World Heritage Site by UNESCO.
  • Thailand also declared it a National Park to preserve the water shed forest there.
  • Pang Sida comprises lush jungle mountains with valleys, cliffs and waterfalls.
  • The vegetation ecosystem is Tropical Rain Forest, Tropical Evergreen Forest, Deciduous Dipterocarp, Mixed Deciduous Forest and Hill Evergreen Forest.

Ecosystem at Khao Yai and Pang Sida Region
  • The complex has a well defined topographic, climatic and vegetation east-west gradient. It contains all major habitat types of eastern Thailand and at least 2500 plant species are recorded ( 16 endemic ) of the 20,000 to 25,000 species estimated for Thailand.
  • Within the area three main types of vegetation are dominant: evergreen forests ( 73.8% of all five reserves ), mixed dipterocarp deciduous forest ( 5.3% ) and deforested scrub, grassland and secondary growth ( 18% ). The first two categories, with karst and riverine ecosystems, comprise the most significant habitats.
  • The evergreen forests are of three types: dry ( 28.7% ), moist evergreen above 600 meters ( 25.8% ) and hill and lower montane rainforests ( 19.3% ). They provide a wide range of ecosystems and habitats. The dipterocarp deciduous mixed forests provide a similarly wide range but in drier fire-prone areas with sandy soils. As well as mixed forests the drier areas include dry dipterocarp forest and grassland.
  • The small area of karst in the northwest of Khao Yai National Park has distinctive microhabitats. Riverine ecosystems wind through other forest types, with distinct features and limited habitats such as cascades, waterfalls and deep pools.
  • More than 80% of Khao Yai National Park is covered in evergreen or semi-evergreen forest, much of it tall, good quality primary forest. Moist and dry evergreen forests also occur in the other protected areas of the complex: Thap Lan 59%, Pang Sida 86.5%, Ta Phraya 72.5%, and Dong Yai 70.6%. A greater proportion ( 32% ) of Thap Lan has been degraded, mostly through loss of dry dipterocarp forest by clearing for agriculture and tree plantations in the northern and northwestern sections. However, it also has about 700 hectares of the fan-leafed corypha or lan palm, on the leaves of which Buddhist sermons were originally inscribed.
  • Pang Sida has wide south-facing hill-slope habitats. There are also extensive areas of bamboo forest.
  • In Ta Phraya 25% and in Dong-Yai almost 20% of the land is grassland or scrub. The protected areas in the DPKY complex were logged to a varying extent prior to the declaration of the 1989 logging ban by the Thailand Government, with secondary regrowth forest succession evident in many areas. Nevertheless, there are significant core areas of primary forest in all protected areas of the complex, as evidenced in a low altitude overflight during the evaluation mission.

Animal Species at Khao Yai and Pang Sida Region
  • The complex contains more than 800 fauna species, and protects some of the largest remaining populations in the region of many important wildlife species.
  • A total of 112 species of mammals are known from the four parks: in Khao Yai 72 species, Thap Lan 76 species, Pang Sida 85 species and Ta Phraya 21 species. Complete data are not yet available for Dong Yai but the wildlife sanctuary is known to contain important large mammal species. Globally threatened mammals found in the complex include the Asian Elephant, Tiger, Leopard Cat, Clouded Leopard, Marbled Cat, Asian Golden Cat, Pigtailed Macaque, Stump-tailed Macaque, Pileated Gibbon, Asiatic Black Bear, Malayan Sun Bear, Asiatic Wild Dog, Large Spotted Civet, Malayan Porcupine, Wild Pig, Serow, Banteng and Gaur. The karst area has endemic species of reptiles and bats ( 63 reptile species are recorded in Khao Yai ).  Important riverine species include the Smooth-coated Otter and the endangered Siamese Crocodile, rediscovered in Pang Sida NP in 1992. The Department of National Parks, Wildlife and Plant Conservation is currently implementing a scientifically controlled crocodile re-introduction programme in Pang Sida NP in collaboration with Mahidol and Kasetsart Universities.
  • Khao Yai National Park is scientifically important at a global scale, as it is the only known location where White-handed and Pileated Gibbon species have overlapping ranges and interbreed. Other notable species found in the complex include: Long-tailed Macaque, Silvered Langur, White-handed Gibbon, Slow Loris, Malayan Pangolin, Black Giant Squirrel, Hairy-footed Flying Squirrel, Whitehead’s Rat, Brush-tailed Porcupine, Palm Civet, Binturong, Marbled Cat, Jungle Cat and Leopard. There are also unconfirmed reports of Wild Water Buffalo. Recent surveys of herpetofauna indicate more than 200 species of reptiles and amphibians, with nine endemic species.

Bird Species at Khao Yai and Pang Sida Region
  • A total of 392 species of birds have been recorded within the DPKY-FC:
  • Khao Yai 358 species,
  • Thap Lan 284 species,
  • Pang Sida 238 species and
  • Ta Phraya 200 species.
  • The complex provides resident habitat for three globally threatened bird species: Pale-capped Pigeon and Silver Oriole ( evergreen forest ), Green Peafowl ( dipterocarp/ deciduous forest ) and Masked Finfoot ( riverine habitat ). In addition, 53 species considered nationally threatened or near threatened occur including four species of hornbill. Some 12.5% of birds are vagrant or passage migrants, including the Spot-billed Pelican and Greater Adjutant.
