Mangrove case study

Often the local poor people are used to destroy the forests taking tolls many times higher than government rate from them illegally. It is not uncommon for a mangrove forest in the Caribbean to feature only three or four tree species.

The most immediate threat is over-exploitation, both of timber resources, which may have already taken place, and also of the fauna. Shrimps and mud lobsters use the muddy bottoms as their home. However, recent research suggests the older, yellowing leaves have no more measurable salt content than the other, greener leaves.

Describe the role and responsibility of the Government of Bangladesh towards the Sundarbans In addition to Mangrove case study own role, the Bangladeshi government must also take on the responsibility of providing for the World Heritage Site, which was designated in These findings have implications for coastal zone management in Asia in the face of climate change.

EPIC seeks new evidence for the capacity of healthy and well-managed ecosystems to prevent or mitigate disasters from tsunamis and the extreme weather events provoked by climate change.

Top-dying of sundri is most likely associated with the decrease in freshwater flow, either as a direct effect of increasing salinity or other associated edaphic changes.

Marvellous Mangroves in China

About species are considered "mangroves", in the sense of being a tree that grows in such a saline swamp, [4] though only a few are from the mangrove plant genus, Rhizophora.

Since then initiatives have been taken to re-orient the policies with current need, particularly as they relate to the depletion of forestry resources owing to numerous socio-economic factors. Among the many which may be readily seen by the visitor are no less than nine species of kingfisher, including brown-winged and stork-billed kingfishers, Pelargopsis amauropterus NT and P.

The integrated management of wood and non-wood resources depends upon an understanding of the ecological and silvicultural parameters of forest management, and the biological role that primary production from the forest plays in the mangrove food web of aquatic resources. Though the trees themselves are few in species, the ecosystem that these trees create provides a home habitat for a great variety of other species.

The surface is clay except on the seaward side of islands in the coastal limits, where sandy beaches occur. They will serve as the basis for the development of country-specific long term protection concepts. The area supports a varied insect population including large numbers of honey- bees, honey and beeswax being among the economically important products.

High tide brings in salt water, and when the tide recedes, solar evaporation of the seawater in the soil leads to further increases in salinity. Once a propagule is ready to root, its density changes so the elongated shape now floats vertically rather than horizontally. The Sundarbans Reserve Forests composed of 0.

They are responsible as a state to preserve the forests and mangroves of the Sundarban, but also to create a dynamic economic community within them, and to utilise fully the resources which they provide in a self sustaining manner.

Some 53 reptile species and eight of amphibians have been recorded Hussain and Acharya, The eighteen recorded snake species include king cobra Ophiophagus hannah and spectacled cobra Naja naja, three vipers and six sea-snakes Salter, Cyclones and tidal waves Mangrove case study some damage to the forest along the sea-face, and are reported to result occasionally in considerable mortality among spotted deer.

This area is approximately half the size of the area of mangrove that existed years ago, the other half being cleared and converted to agricultural land Hussain and Archarya Black mangroves live on higher ground and make many pneumatophores specialised root-like structures which stick up out of the soil Mangrove case study straws for breathing which are also covered in lenticels.

Mangrove plantations in VietnamThailandPhilippines and India host several commercially important species of fishes and crustaceans.

The main reasons of the depletion of this forest are due to the corruption and negligence of the some Forest Department staffs, illegal traders, local influential leaders, some government officials concerned, and sections of the media and police forces.

For comparison, the tropical rainforest biome contains thousands of tree species, but this is not to say mangrove forests lack diversity. The Sundarbans constitute about 45 percent of the natural productive forests and provide livelihood for at least 0.

In addition to their collaboration in the tree nurseries, environmental education centers and demonstration gardens will be established to inform school classes, tourists and local residents about the importance of and threats to mangroves, and conservation measures as well as the sustainable use of the mangrove ecosystems.

In a frequently cited concept that has become known as the "sacrificial leaf", salt which does accumulate in the shoot sprout then concentrates in old leaves, which the plant then sheds. Conditions are most saline in February-April, the depletion of soil moisture being coupled with reduced freshwater flow from upstream.

If it does not root, it can alter its density and drift again in search of more favorable conditions. The only primate is rhesus macaque Macaca mulatta, considered by Blower to number in the region of 40, to 68, based on surveys by Hendrichs and Khanrespectively, as compared to the much higher estimate ofderived by Gittins Mangrove seeds are buoyant and are therefore suited to water dispersal.

The Sundarbans of Bangladesh and India support one of the largest populations of tiger Panthera tigris ENwith an estimated in that of the former Hendrichs, Scott gives further details of the avifauna. The roots also contain wide aerenchyma to facilitate transport within the plants.

There are also three species of monitor, Varanus bengalensis, V. The most recent incidence due to ship wreckage occurred in August when a Panamanian cargo ship capsized near Dangmari Forest Station.

Anthony Calfo, a noted aquarium author, observed anecdotally a red mangrove in captivity only grows if its leaves are misted with fresh water several times a week, simulating frequent tropical rainstorms.

Herons, egrets, storks, sandpipers, whimbrel, curlew and numerous other waders are to be seen along the muddy banks and on the chars or sandbanks which become exposed during the dry season. The pH averages 8.This publication, Economic Analysis of Mangrove Forests: A case study in Gazi Bay, Kenya is prepared as part of the efforts of the United Nations Environment Programme of promoting coastal intertidal forests as a significant green economy asset.

MANGROVE SWAMPS CASE STUDY; THE SUNDARBANS OF BANGLADESH. The Quality and Status of the Existing Mangrove; PHYSICAL FEATURES The Sundarbans, covering some 10, of land and water, is part of the world's largest delta (80, formed from sediments deposited by three great rivers, the Ganges, Brahmaputra and Meghna, which converge on the Bengal Basin.
