Central Highlands of Sri Lanka - Declared as a World Heritage site by UNESCO in 2010.

Sri Lanka's highlands are situated in the south-central part of the island. The property comprises the Peak Wilderness Protected Area, the Horton Plains National Park and the Knuckles Conservation Forest. These montane forests, where the land rises to 2,500 meters above sea-level, are home to an extraordinary range of flora and fauna, including several endangered species such as the western-purple-faced langur, the Horton Plains Slender Loris and the Sri Lankan leopard. The region is considered a super biodiversity hotspot.

Outstanding Universal Value

The Central Highlands of Sri Lanka is a serial property comprising three component parts: Peak Wilderness Protected Area, Horton Plains National Park and Knuckles Conservation Forest. Its forests are globally important and provide habitat for an exceptional number of endemic species of flora and fauna. The property includes the largest and least disturbed remaining areas of the sub montane and montane rain forests of Sri Lanka, which are a global conservation priority on many accounts. They include areas of Sri Lankan montane rain forests considered as a super-hotspot within the Western Ghats and Sri Lanka biodiversity hotspot. More than half of Sri Lanka’s endemic vertebrates, half of the country’s endemic flowering plants and more than 34% of its endemic trees, shrubs, and herbs are restricted to these diverse montane rain forests and adjoining grassland areas.

The property includes the largest and least disturbed remaining areas of the sub montane and montane rain forests of Sri Lanka, which are a global conservation priority on many accounts. The component parts stretch across the Ceylonese rain forest and the Ceylonese monsoon forest. In the montane forests represented by the three serial properties, the fauna elements provide strong evidence of geological and biological processes in the evolution and development of taxa. The endemic purple-faced langur of Sri Lanka (Semnopithecus vetulus) has evolved into several morphologically different forms recognizable today. The Sri Lankan leopard, the only representative in the island of the genus Panthera, which diverged from other felids about 1.8 million years ago, is a unique sub-species (Panthera pardus kotiya). All three nominated properties provide habitat to this subspecies of leopard, endemic to Sri Lanka. Long isolation and the concomitant evolutionary processes have also resulted in a Sri Lankan molluscan fauna that is the most distinct in the South Asian region.

Integrity

The small size of the components of the nominated property is a result of the limited extent of the most significant rain forest areas remaining on Sri Lanka. However, provided the property is effectively protected and managed, these areas are sufficient, especially since many of the plant and animal species have highly localized distributions. The boundary of the Peak Wilderness Protected Area includes a range of protected zones, and this component has a common boundary with the Horton Plains National Park. Effective arrangements to protect the properties from the impacts of surrounding land-use, as well as to address a range of threats are required, including via functioning buffer zones.
