In 2019 a total area of 16.5% [2] of Sri Lanka was forested. In 2010, it was 28.8% [3] (and 32.2% in 1995. [4]) 9.0% [5] of Sri Lanka's forests are classified as primary forest (the most biodiverse form of forest and the biggest carbon sinks on Earth). Sri Lanka's forests contain 61 million metric tons of carbon in living forest biomass (in ...
The Loris, found only in Sri Lanka and South India, is related to the Lemurs of Madagascar. The connection to India led to a commonality of species, e.g. freshwater fish, the now extinct Sri Lankan Gaur (Bibos sinhaleyus) and the Sri Lankan Lion (Panthera leo sinhaleyus). [5] The island was connected, off and on at least 17 times in the past ...
The following list provides the 704 species of common trees and shrubs of flora of Sri Lanka under 95 families. The list is according to A Field Guide to the Common Trees and Shrubs of Sri Lanka, by Mark Ashton, Savitri Gunatilleke, Neela de Zoysa, M.D. Dassanayake, Nimal Gunatilleke and Siril Wijesundera. [1]
More than 90% of Sri Lanka's surface lies on Precambrian strata, some of it dating back 2 billion years. [6] The granulite facies rocks of the Highland Series (gneisses, sillimanite-graphite gneisses, quartzite, marbles, and some charnockites) make up most of the island and the amphibolite facies gneisses, granites, and granitic gneisses of the Vijayan Series occur in the eastern and ...
The ecoregion covers an area of 48,400 square kilometers (18,700 sq mi), about 75%, of the island of Sri Lanka, with the exception of the islands' southwestern corner and Central Highlands, home to the Sri Lanka lowland rain forests and Sri Lanka montane rain forests ecoregions, respectively, and the northern Jaffna Peninsula, which is part of the Deccan thorn scrub forests ecoregion.
Sri Lanka is known to be home to 794 species of Hemipterans. Detailed work of Sri Lankan hemipterans are recorded in the book Catalogue of Hemiptera of Sri Lanka. Sri Lanka comprises 74 species in 46 genera and 6 families of aphids within the order Hemiptera. 2 endemic aphid species are found on Sri Lanka
The Sri Lanka lowland rain forests represents Sri Lanka's Tropical rainforests below 1,000 m (3,281 ft) in elevation in the southwestern part of the island. The year-around warm, wet climate together with thousands years of isolation from mainland India have resulted in the evolution of numerous plants and animal species that can only be found ...
The hilly virgin rainforest, part of the Sri Lanka lowland rain forests ecoregion, was saved from the worst of commercial logging by its inaccessibility, and was designated a World Biosphere Reserve in 1978 and a World Heritage Site in 1988. Because of the dense vegetation, wildlife is not as easily seen as at dry-zone national parks such as Yala.
