Lawachara National Park
Lawachara is about 160 km (99 mi) northeast of Dhaka and 60 km (37 mi) from Sylhet. It is 8 kilometres (5.0 mi) from the town of Srimongal.
The terrain of Lawachara is undulating with scattered 10 to 50 m (33 to 164 ft) hillocks. Locally known as tila, the hillocks are primarily composed of Upper Tertiary soft sandstone. The park is crossed by numerous sandy-bedded streams (locally known as nallah), one of which is the Lawachara tributary, from which the park derived its name.The soil of Lawachara is alluvial brown sandy clay loam to clay loam dating from the Pliocene epoch. Shallow depressions filled with water (haor wetlands) are also a feature of the region as the low-lying areas are often subject to flooding.
The climate of Lawachara is generally pleasant to warm, averaging at 26.8 °C (80.2 °F) in February to 36.1 °C (97.0 °F) in June. The humidity is high throughout the year, and Lawachara experiences frequent rains with occasional cyclonic storms.
Biological diversity in the Lawachara National Park consists of 460 species, of which 167 species are plants, 4 amphibian species, 6 reptile species, 246 bird species, 20 mammal species, and 17 insect species. One of this is the critically endangered western hoolock gibbons, of which only 62 individuals remain in the area.
Mammals found in Lawachara include slow lorises (Nycticebus), the Northern pig-tailed macaques (Macaca leonina), rhesus macaques (Macaca mulatta), Assamese macaques (Macaca assamensis), capped langurs (Trachypithecus pileatus), Phayre’s leaf monkeys (Trachypithecus phayrei), western hoolock gibbons (Hoolock hoolock), golden jackals (Canis aureus), Dholes (Cuon alpinus), Asian black bears (Ursus thibetanus), yellow-throated martens (Martes flavigula), tigers (Panthera tigris), leopards (Panthera pardus), fishing cats (Prionailurus viverrinus), leopard cats (Prionailurus bengalensis), wild pigs (Sus scrofa), sambar (Rusa unicolor), barking deer (Muntiacus), and Indian giant squirrels (Ratufa indica).
The western hoolock gibbon (Hoolock hoolock) is a higher primate found in Bangladesh. It is one of the top 25 most endangered primates and one of the six non-human primate species found in Lawachara. In a census in 2007, only 62 individuals in 17 groups were found in Lawachara and in the greater West Bhanugach Reserved Forest. Yet this is the biggest surviving gibbon population in Bangladesh. The Lawachara population is considered of ciritical importance as it is likely to be the last viable population of western hoolock gibbons that will survive into the next century.
