Abstract The design and methods are described of farmer-managed action-research to test the survival and performance of trees planted in paddy fields of private farms in Bangladesh. Farmers received seedlings of indigenous and exotic trees with extension advice on planting methods and care. Planting was done in systematically designed randomized modules involving twelve thousand trees up to the end of 1990. Survival and condition of individual seedlings were monitored twice annually, and mortality was replanted for up to three years after which little further mortality occurred. Stocking rate, including original survivors and replanted seedlings, tended towards 55% after six years. The main factors conductive to survival were the presence of a ‘nurse’ crop in the field at the time of tree planting, and the quality and size of planting stock. Cause of death could not be attributed in about 8% of mortality. Main recorded causes of tree mortality, in order of frequency, were livestock browsing, physical damage during cultivation or harvesting operations, pests or diseases, drought, and flooding. About 15% of tree mortality was due to losses of complete modules owing to catastrophic flooding, land disputes, and public works such as roads or pipelines. It is suspected that some of this mortality may be unacknowledged changes of mind and deliberate removal by the participating farmers.
