Horton Plains National Park

Horton Plains National Park is a protected area in the central highlands of Sri Lanka and is covered by montane grassland and cloud forest. This plateau at an altitude of 2,100–2,300 metres (6,900–7,500 ft) is rich in biodiversity and many species found here are endemic to the region. This region was designated a national park in 1988. It is also a popular tourist destination and is situated 8 kilometres (5.0 mi) from Ohiya, 6 kilometres (3.7 mi) from the world famous Ohiya Gap/Dondra Watch and 32 kilometres (20 mi) from Nuwara Eliya. The Horton Plains are the headwaters of three major Sri Lankan rivers, the Mahaweli, Kelani, and Walawe. In Sinhala the plains are known as Maha Eliya Plains (මහ එළිය තැන්න). Stone tools dating back to Balangoda culture have been found here. The plains' vegetation is grasslands interspersed with montane forest and includes many endemic woody plants. The mean annual rainfall is greater than 2,000 millimetres (79 in). Frequent cloud cover limits the amount of sunlight that is available to plants. The mean annual temperature is 13 °C (55 °F) but the temperature varies considerably during the course of a day, reaching as high as 27 °C (81 °F) during the day time, and dipping as low as 5 °C (41 °F) at night. During the southwest Monsoon season, the wind speed sometimes reaches gale force. Although some rain falls throughout the year, a dry season occurs from January–March. The ground frost is common in February. Mist can persist in the most of the day during the wet season.Many pools and waterfalls can be seen in the park, and Horton Plains is considered the most important watershed in Sri Lanka.The Horton Plains are the headwaters of important rivers such as the Mahaweli, Kelani, and Walawe. The vertebrate fauna of the region includes 24 species of mammals, 87 species of birds, nine species of reptiles and eight species of amphibians.The Sri Lankan elephant disappeared from the region in the 1940s at the latest.At present, the largest and the most commonly seen mammal is the sambar deer. Some research findings estimate the population of sambar deer to be around 1500 to 2000, possibly more than the carrying capacity of the plains.
