Use of indicators for monitoring the biodiversity health status of mangroves is an innovative approach for Bangladesh mangroves as well as the global mangrove resources. Identification of effective indicators for such purposes needs long drawn studies over decades, but the use of experiences and observations is no less valuable in putting up a list of ‘initially identified indicators’ for the purpose. In the context of the Sundarbans, the experience in the use of this experimental approach coupled with the field verification by experts is presented in this paper.
