Horton Plains National Park

Horton Plains National Park

    Horton Plains National Park is a protected area in the central highlands of Sri Lanka and is covered by montage grassland and cloud forest. This plateau at an altitude of 2,100–2,300 meters (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 kilometers (5.0 mi) from Ohiya, 6 kilometers (3.7 mi) from the world-famous Ohiya Gap/Dondra Watch and 32 kilometers (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. 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. Large herds of Sri Lankan sambar deer feature as typical mammals and the park is also an Important Bird Area with many species not only endemic to Sri Lanka but restricted to the Horton Plains. Forest die back is one of the major threats to the park and some studies suggest that it is caused by a natural phenomenon.

The sheer precipice of World's End and Baker's Falls are among the tourist attractions of the park.

In 20th century there are some records of elephants again in the park.

Physical Features

Waterfall in the national park

    Horton Plains is located on the southern plateau of the central highlands of Sri Lanka. The peaks of Kirigalpoththa (2,389 meters (7,838 ft)) and Thotupola Kanda (2,357 meters (7,733 ft)), the second and the third highest of Sri Lanka, are situated to the west and north respectively. The park's elevation ranges from 1,200–2,300 metres (3,900–7,500 ft). The rocks found in the park belong to the Archaean age and belong to the high series of the Precambrian era and are made up of Khondalites, Charnockites and granitic gneisses. The soil type is of the red-yellow podsolic group and the surface layer is covered with decayed organic matter.

     The mean annual rainfall is greater than 2,000 millimeters (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 plains also feeds Belihul Oya, Agra Oya, Kiriketi Oya, Uma Oya, and Bogawantalawa Oya. Due to its high elevation, fog and cloud deposit a considerable amount of moisture on the land. Slow moving streams, swamps, and waterfalls are the important wetland habitats of the park.

History

      The original name of the area was Maha Eliya Thenna ("great open plain"). But in the British period the plains were renamed after Sir Robert Wilmot-Horton, the British governor of Ceylon from 1831 to 1837, who travelled to the area to meet the Ratemahatmaya of Sabaragamuwa in 1836,[4] in 1834 by Lt William Fisher of the 78th Regiment and Lt. Albert Watson of the 58th Regiment, who 'discovered' the plateau. Stone tools dating back to Balangoda culture have been found here. The local population who resided in the lowlands ascended the mountains to mine gems, extract iron ore, construct an irrigation canal and fell trees for timber. A 6-meter (20 ft) pollen core extracted from a mire revealed that in the late Quaternary period the area had a semi-arid climate and a species-restricted plant community.

      Since Sri Lanka has a long non-written history, there is a significant and logical folk story, which also goes with the epic 'Ramayana' with some deviations. It is believed that Thotupala mountain in Horton plain to be the place where King Rawana landed his aircraft, 'Dandumonaraya'. According to the story King Rawana kidnapped Sitha, who was the wife of Rama as a revenge for cutting King Rawana's sister, Suparnika's nose. It provoked Rama in India and he led an army that consisted of monkey like humans, whose leader was Hanuman. In the story, Hanuman set fire to Horton plains and that fire lasted for a long time. The original name, Maha Eliya Thenna carries the meaning, 'The hugely lighten ground'. Even now the upper layer of soil can be seem in a blackish grey color. There had been some soil tests done by local universities,and it revealed that upper layer contains a high amount of Calcium Carbonate and Potash. For Sri Lankans, Horton Plains is very significant in their History and Culture.

      Sir Joseph Dalton Hooker had advised the British Government "to leave all Montane Forests above 5000 ft. undisturbed" and an administrative order to this effect had been issued in 1873 that prevented clearing and felling of forests in the region. Horton Plains was designated as a wildlife sanctuary on 5 December 1969, and because of its biodiversity value, was elevated to a national park on 18 March 1988. The Peak Wilderness Sanctuary which lies in west is contiguous with the park. The land area covered by Horton Plains is 3,160 hectares (12.2 sq mi). Horton Plains contains the most extensive area of cloud forest still existing in Sri Lanka. On July 2010, the Central Highlands of Sri Lanka which incorporates Horton Plains National Park, Peak Wilderness Sanctuary and Knuckles Mountain Range was inscribed on the World Heritage List.

Flora

        Shrubs with pink flowers Rhododendron arboretum is the predominant tree species in the park
The vegetation of the park is classified into two distinctive groups, 2,000 hectares (7.7 sq mi) of wet patana (Sinhalese for "montane grasslands") and 1,160 hectares (4.5 sq mi) of subtropical montane evergreen forests. Nearly 750 species of plants belonging to 20 families have been recorded from the park. The forest canopy reaches the height of 20 meters (66 ft) and features Calophyllum walkeri, forming communities with varieties of Myrtaceae species such as Syzygium rotundifolium, and S. sclerophyllum, and Lauraceae members including Litsea, Cinnamomum, and Actinodaphne speciosa. The undergrowth layer is characterised by Strobilanthes spp. The thickness of the Strobilanthes vegetation hinders the development of a herb layer. Dwarf bamboo species such Indocalamus and Ochlandra also found in the undergrowth layer. Rhodomyrtus tomentosa bushes specially grow in forest margin and near the mountain peaks. Species such as Gordonia and Rhododendron arboreum have spread to Sri Lanka, along the Western Ghats of South India from the Himalayas and are now common. Nearly 54 woody plant species have been recorded from the park, of which 27 (50%) are endemic to Sri Lanka.

Fauna

      Sri Lankan sambar deer occur in large herds.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. Other mammal species found in the park include Kelaart's long-clawed shrews, toque macaques, purple-faced langurs, rusty-spotted cat, Sri Lankan leopards, wild boars, stripe-necked mongooses, Sri Lankan spotted chevrotains, Indian muntjacs, and grizzled giant squirrels. Fishing cats and European otters visit the wetlands of the park to prey on aquatic animals. A subspecies of red slender loris, the Horton Plains slender loris (Loris tardigradus nycticeboides formerly sometimes considered as Loris lydekkerianus nycticeboides) is found only in highlands of Sri Lanka and is considered one of the world's most endangered primates. In July 2010 a group of researchers from the Zoological Society of London was able to photograph the mammal for the first time.

In 2016, rusty-spotted cats (Prionailurus rubiginosus) were recorded in Horton Plains National Park for the first time, at altitudes of 2,084–2,162 m (6,837–7,093 ft).[13]

Tourist attractions

World's End is a major attraction

     Horton Plains is a popular tourist destination, with World's End being the key attraction. In the six months ending in August 2009, Horton Plains National Park earned a revenue of Rs. 20.1 million (US$ 0.17 million). The park is accessed by the Nuwara Eliya-Ambewela-Pattipola and Haputale-Boralanda roads, and there are railway stations at Ohiya and Ambewela.

World's End is a sheer precipice with a 870 m (2,854 ft) drop.[6] It is situated at the southern boundary of the park. Another cliff known as the Lesser World's End of 270 m (886 ft) is located not far from World's End.

Baker's Falls, a waterfall formed by Belihul Oya, a tributary of the Walawe River is named after Sir Samuel Baker, a hunter and explorer who attempted to establish a European agricultural settlement at Nuwara Eliya. The waterfall is 20 meters (66 ft) high. Slab Rock Falls is another well-known waterfall in the plains. The waterfall can be reached by walking on one of the main trails; the trail is a bit steep at the end but the difficulty level is medium to easy.
