Abstract/ Executive Summary:

In a study conducted in three southern districts (Bhola, Borguna and Patuakhali) of Bangladesh, a total of 69 tree species was recorded from the home gardens, of which 32 were fruit tree and 37 were timber tree species. Among the fruit tree species, coconut, betel nut, mango, jackfruit , guava, velvety apple were found in more than 80% households. The stocking of fruit trees per homestead was found highest for betel nut (265) followed by velvety apple (212), mango (38) coconut (25), jackfruit (20) and guava (9). Among the timber tree species, rain tree, mehogoni, rajkoroi were most prevalent and found in more than 65% homesteads. The stocking of timber trees/ homestead was found highest for mehogoni (79) and then for rain tree (57), raj koroi (29) and katbadam (6).

Objectives:

To identify fruit and timber tree species and their distribution pattern in the coastal homesteads of Bangladesh .

Methodology:

The coastal zone of Bangladesh forms the lowest landmass and is a part of the delta of the extended Himalayan drainage ecosystem and covers 19 coastal districts. Among them three districts namely Bhola, Borguna and Patuakhali were selected for the present study. These coastal districts lie between the latitude 22°10'-22°39N and longitude 90°39'- 91⁰05'E. The climate is humid. Temperature ranges between 18° and 32° Celsius. The amount of rainfall varies between 2000-2500 mm at Borguna, 2500-3000 mm at Patuakhali and 3000 mm at Bhola district (Siddiqi and Khan 2004). Soils in the delta consist primarily of sands, silts, silty sands, sandy silts and clayey silts (Anon 1987). The delta soils occur in the coastal region of the Ganges tidal flood plain , the young Meghna estuarine flood plain and the old Meghna estuarine flood plain. The estuarine floodplain landscape occupies Bhola and Borguna districts. The landscape has been formed by the combined actions of rivers Meghna, Brahmaputra and Ganges. Usually, silty and clay deposits are finely stratified, and sandy deposits, as well as mixed sandy and silty deposits are coarsely stratified. The greater part of Borguna district consists of Gangetic meander floodplain soil having non-calcareous grey floodplain soil. Information was collected through a semi structured questionnaire and field survey which included interviews, group discussion and field observations. The respondents from selected homestead were interviewed with this pre-formulated questionnaire . Information was recorded through interview of family members like head of the family, housewife and others. The name and number of different timber and fruit tree species from sapling to big trees were recorded from the selected homesteads . The survey was conducted during January-March 2010. Microsoft Excel was used to process and analyze the collected data

Achievement/Findings:

This information might help to understand the tree diversity, and selection of salt tolerant species of any environmental stress condition. Present study reveals only occurrence and diversity of different fruit and timber tree species in the coastal regions, but intensive research should be undertaken to improve home gardens for more productivity.
