Vientiane Province
Phou Khao Khouay National Biodiversity Conservation Area is a protected area 40 kilometres (25 mi) northeast of Vientiane. It was established on 29 October 1993 covering an area of 2,000 km2 extending into Khet Phiset Xaisomboon (special zone), Vientiane prefecture, and Vientiane province. Its mountainous topography, with elevation varying from 200 m to 1761 m, emerged from "uplifting and exposure of the underlying sedimentary (Indosinias schist-clay-sandstone) complex". Sandstone is also seen spread in layers. extensive flat uplands with sandstones with hardly any soil cover are also part of the topography of the park. It has a large stretch of mountain range with sandstone cliffs, river gorges and three large rivers with tributaries which flow into the Mekong River. It has monsoonal climate with recorded annual rainfall of 1936 mm (with higher reaches recording more rainfall). The mean annual temperature is 26.6 °C with a mean maximum of 31.6 °C and a mean minimum temperature of 21.5 °C. The forests are evergreen, Shorea mixed deciduous forest, dry dipterocarp and pine type; particularly coniferous forest, of mono specific stands of Pinus merkusii, Fokienia hodgsonsii, bamboo (mai sanod), and fire-climax grasslands. Animals found here include elephants, tigers, bears, white-cheeked gibbons, and langurs and many species of reptiles, amphibians, and birds. The green peafowl has been reported here, near Ban Nakhay and Ban Nakhan Thoung, although it was generally considered to be extinct in Laos; conservation management has increased its population.
