MANAGEMENT AND MITIGATION OF BIODIVERSITY:Short Term Process
- Preparation of national biodiversity strategies and action plan in line with CBD and its appropriate implementation;
- Strengthening the national institution and capacity building for conservation and management of biodiversity;
- Promote community based biodiversity conservation and management
- Preparation of National Biosafety Framework
- Implementation of effective ecosystem approach community based conservation programme involving stakeholders/local communities;
- Development of detailed guidelines for freshwater, coastal and marine biodiversity conservation
- Adaptive measures of adverse impact caused by cyclone and flood and anticipated global warming and sea level rise.

Coastal Biodiversity of Bangladesh
Bangladesh has
the world’s longest beach (710 km) along the Bay of Bengal,
filled with a rich and unique coastal biodiversity. It has a great natural and
because of its outstanding aesthetic value. It also provides multiple renewable
resources of direct economic benefits to the nation.

Wetland Biodiversity in the Haor Basin
It is estimated that about 50 percent or more of the land surface of Bangladesh is wetland, consisting of about 700 rivers, creeks, streams, and other water bodies known locally as Haor, baor, heel and khal. There are also the vast estuarine systems and mangrove swamps of the south and southeast regions, as well as innumerable man-made water bodies of various size.

Fauna: BIODIVERSITY DEPLETION
Aquatic invertebrates:
In Bangladesh there are about 362 species of molluscs, of which 336 are marine and 26 are freshwater (Table-1). Law-lying marshlands are the best habitat for them.
Shrimp:
Bangladesh earns a good amount of foreign exchange from the export of shrimp and prawn. Shrimp export brings in the most attractive financial returns.
Turtles and Tortoises
About 12 species of reptile are critically endangered, including the estuarine crocodile, Genetic gharial, river terrapin, tortoise, turtle, flying lizard, and reticulated python.
Birds:
The population of birds in Bangladesh is still very rich, and there is a wide variety in the country (Table-1). However, bird population around the globe are declining at an alarming rate, and that does not exclude Bangladesh. IUCN’s Red list (2000) revealed that among 388 species of resident birds, 41 species are threatened in this country. The primary threats to them are habitat destruction, illegal trade, and over hunting.
Threatened Plants:
A tentative list of about 26 angiosperm species endangered in Bangladesh was prepared by Khan (1991a) as the first step in intensive field studies to locate the species in the wild, the collect relevant data. This is being followed up by screening, preparing status reports, reviewing information, and analysis of the data to assign the species to the IUCN Red list categories (IUCN. 1994). It is still premature to categorically name the endangered plants of Bangladesh until the field surveys are completed. But the current project for a Red Data Book of Bangladesh Plants taken up by BNH is nearing completion. The list of threatened plants has been expanded to more tan 100 number.
Forests:
Most of the forests of Bangladesh are located in the Greater Districts of Chittagong, Chittagong Hill Tracts (CHT), Sylhet, Khulna, Dhaka, Mymensingh, and Tangail. The moist deciduous forests are found in Dhaka. Mymensingh, Rangpur, Dinajpur, and Rajshahi districts. In the coastal areas, plantations have been established on they newly accreted char land.
Throughout the country the forestland are largely devoid of adequate natural cover, except negligible forest pockets. To conserve plants and other biodiversity, the GoB have declared a number of protected areas throughout the country.

Flora: BIODIVERSITY DEPLETION
Natural forests throughout the country are increasingly being depleted. Various types of development activity, such as dikes, highway, road construction, and other infrastructure development have further intensified deforestation, and destruction of natural forests in Bangladesh. Briefly, the other causes of deforestation are listed below.

Habitat Depletion and Over Exploitation: BIODIVERSITY DEPLETION
Fish
The people of Bangladesh largely depend on fish to meet their protein needs, especially the poor in rural areas, several decades ago there was an abundance of fish in this country. But recently, capture fish production has declined to about 50 per cent, with a negative trend of 1.24 per cent per year (Ahmed, 1995b). Despite the constant depletion of the river, canal, and flood plain habitats for years, Bangladesh still holds the worlds most diverse and abundant inland fisheries. But the availability of many species that were very popular locally has been drastically decreased, and some are no longer found in the country.

Reasons for Loss of Biodiversity in Bangladesh
- High population pressure
- Extreme poverty
- Natural hazard
- Deforestation
- Over exploitation of biological resources
- Destruction of habitat
- Water pollution and flood control related activities
- Salinity intrusion/high salinity
- Land use change and land use conflict
- Shifting cultivation in the hills

Biodiversity Depletion
Biodiversity influences people’s economic, social and cultural development and hence their quality of life; The knowledge, cultural traditions, innovations, and management practices of indigenous communities, and the traditional practices of farmers, and rural communities concerning biodiversity constitute the basis for sustaining both biodiversity and human life. However, biodiversity is being threatened in Bangladesh by the destruction of natural habitats due to the failure to recognize the social, economic, and cultural value of biodiversity. This threat and the concomitant destruction are likely to increase as population growth continues. It is believes that the problem may minimized through effective implementation of ecosystem based conservation of biodiversity involving community peoples.
