Threats

The SRF is as well as a deeply densely populated place, for that excuse human pressure is important. Around 1.2 million local users reside seasonally in the place for fishing and totaling resource use deeds. Commercial hunting was a problem mainly in the in the by now the 1970s and this resulted particularly in a immense depletion of the crocodile populations and to a lesser extent to the deer population. Although the sponsorship has bigger significantly in the last decades, illegal hunting is yet happening on the order of an incidental basis and fishery is having an adverse impact in this area the populations of the surviving turtle and crocodile populations as these animals drown frequently in fishing nets.

Due to natural processes the role of the Sundarban to freeing the water of the Ganges and Brahmaputra catchment is decreasing as main waterways are varying eastwards. As a upshot the salinity of the Sundarban is increasing, particularly in the western region. Further, the sum annual discharge is decreasing due to intensifying home use (dams, irrigation) upstream. The role of this regulate is not yet determined, but is evident that it will influence wildlife populations and vegetation in the long term.

However, the main threat today may arrive from uncovered the place in the form of pollution. On the northern edge of the area, Mongla, Bangladesh second largest harbor, is situated. This harbor and its allied marine traffic is a frequent source of oil spills and there is a enduring risk of accidents then chemicals. Moreover, toxic products (pesticides, etc.) enter the system due to upstream pollution in the big Ganges catchment. Pollution may be a dispatch source of mortality, but it may plus shorten the health, increasing the mortality rate upon the long term. Many products such as pesticides have furthermore been proved to shorten the reproductivity (birth rate) in animal populations.

A highly developed threat is the ill-treatment of mineral gas, which is abundant in the underground of the Sundarban.

Some species extinct during the last century are javan rhinoceros (Rhinoceros sondaicus),water buffalo (Bubalus bubalis),swamp deer (Cervus duvauceli), gaur (Bos gaurus),hog deer (Axis porcinus)
