  abstract = {Sundarbans in Bangladesh has been facing tremendous environmental pollution problems, including that of dieback (top-dying) of the main tree species (Heritiera fomes), and also various health hazards among the surrounding people in Sundarbans, Bangladesh, which is affecting millions of trees and people in Sundarbans areas (Awal, M.A. 2007).

AB  - Sundarbans in Bangladesh has been facing tremendous environmental pollution problems, including that of dieback (top-dying) of the main tree species (Heritiera fomes), and also various health hazards among the surrounding people in Sundarbans, Bangladesh, which is affecting millions of trees and people in Sundarbans areas (Awal, M.A. 2007). The cause of this dieback and health hazard is unknown. The present work has investigated one of the possible factors that might be causing this top-dying, namely the concentrations of various chemical elements present in the sediments, particularly heavy metals, though other chemical parameters such as the pH, salinity, moisture content of the sediment and nutrient status were also assessed. Tree height and trunk diameter were determined as indications of tree growth, counts of seedlings and saplings were made to assess regeneration success, and the intensity of top-dying within the sampled plots was recorded on a rank scale. In order to establish the views of local people about the incidence and causes of top-dying and health hazard, a questionnaire was prepared for asking peoples either individually or in groups. This survey was done among people living or working in the 17 Sub-Districts of Sundarbans, making a distinction between those living within and outside of Sundarbans. So, this survey was performed to receive their indigenous response and knowledge towards top dying, and its present conditions, and their ideas about what leads to top-dying, as well as questions about tree regeneration and human health in Sundarbans.
