There is a well-developed mangrove ecosystem throughout the coastal belt. About 28 species of true mangroves and 18 mangrove associates have been recorded and many of them are shrubs, shorter than 10 m. Most of the mangroves of Sri Lanka belong to the families Rhizophoraceae and Avicenniaceae.
Present status of small-scale exploitation of mangroves in Rekawa Lagoon, Sri Lanka. [ 4 ] Effects of industrialisation and urbanisation on the biology and water quality of three lagoons in southern Sri Lanka viz. Rekawa, Dondra and Galle with reference to water pollution and upstream land uses.
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 ...
Sri Lanka's mangrove forests, small trees that grow in coastal water, have been decreased by 70% since 1915. [7] The size of mangrove ecosystems is being reduced because of the implementation of agriculture and aquaculture systems like fisheries. Shrimp aquaculture projects are one of the biggest threats. The shrimp business is growing very ...
The region was designated as a sanctuary by the Department of Wildlife Conservation in 2008, and it offers a range of ecosystems (mangroves, salt marshes, lagoons, waterholes, and grasslands). In July 2010 it was selected as the fourth Ramsar wetland in Sri Lanka. [2]
Location and relative density of mangroves in South-east Asia and Australasia – based on Landsat satellite images, 2010 [41] Global distribution of threatened mangrove species, 2010 [40] "At the limits of distribution, the formation is represented by scrubby, usually monotypic Avicennia -dominated vegetation, as at Westonport Bay and Corner ...
Muthurajawela is a marsh in Sri Lanka in the southern region of the Negombo lagoon, 30 km (19 mi) north of Colombo.The Muthurajawela Marshes are 3,068 ha (7,580 acres) in area and the country's largest saline coastal peat bog. [1]
Among coastal ecosystems, mangrove forests are of great importance as they account for three quarters of the tropical coastline and provide different ecosystem services. [43] [44] Mangrove ecosystems generally act as a net sink of carbon, although they release organic matter to the sea in the form of dissolved refractory macromolecules, leaves ...
