Question

Role of mangroove in conservation of biodiversity

Answer 1

Mangrove biodiversity and conservation has received significant
importance in the recent past as research has increased the
understanding of values, functions and attributes of mangrove
ecosystems and the role they play in providing important ecological
services and livelihoods for the mangrove associated communities.
Mangroves are unique ecosystems occurring along the sheltered
inter-tidal coastlines, mudflats, riverbanks in association with the
brackish water margin between land and sea in tropical and
subtropical areas. They sustain diverse flora and fauna species in
large proportion and provide many ecosystem services such as
coastal protection from storm, reduction of shoreline and riverbank
erosion, stabilizing sediments and absorption of pollutants.
In all, about 10,000 ha of mangrove vegetation was present in the
country prior to the tsunami and there have been no further
estimates in quantifying the damage to the mangroves from the
tsunami. Coastal areas of Sri Lanka have experienced losses of
mangroves due to various reasons predating the Asian Tsunami..
Many mangrove ecosystems in Sri Lanka have been, and to a large
extent are, indiscriminately exploited for commercial, aquacultural,
agricultural, residential, tourism, mining and industrial development.
They are also being used as dumping grounds for domestic,
agricultural and industrial waste thus posing as imminent threats to
the mangrove habitats. Studies conducted to evaluate the loss by
the tsunami have found that the areas with dense mangrove forests
have reduced the damage to properties by absorbing the tidal
waves.
The destruction of mangrove ecosystems is caused mainly because
of the conservation benefits of mangroves not receiving importance
and the little understanding of the role mangroves play for
sustenance of other economic systems. This has led to mangroves
being considered as wastelands with little use, and no value.
