This framework Study area is adopted from Angelsen & Sal forests constitute about 10% of the Kaimowitz (1999) defo- total forest land (a total of 0.12 million ha) restation model. of Bangladesh (GOB 2010). Until the begin- ning of the 20th century, these forests existed as a continuous belt from the central and northern parts of Bangladesh. Nowadays, they exist mainly in the central part of this country, which is mainly located in the Gazipur, Dhaka, Mymensingh and Tangail districts (Alam et al. 2008 - Fig. 2). The Sal forests ecosystem supports a rich and diverse variety of flora and fauna, though Sal tree (Shorea robusta) is the dominant tree spe- cies (more than 80% in volume - Green 1981, Khan et al. 2007). Out of four catego- ries of forest type in Bangladesh, plain land Sal forests are the most endangered and threatened one, having already faced severe deforestation problems (Safa 2004, Ali et al. 2006). Therefore, this study was conducted at the Central Sal forests of Bangladesh (Fig. 2). Data Collection The study was based on different sources and methods for collecting primary and se- condary data, i.e., several data collection techniques. For primary data we used formal and informal discussion with local people, expert interviews, a case study and direct field observations. On the other hand, secon- dary/literature review were collected through field documents and project reports, peer-re- viewed journals, making use of Bangladesh Forest Department library, exploring reliable relevant online sources and related books. A random sample of 120 forest dependent people was selected (for case study) in equal number for each of the twelve Beats (lowest administrative unit of Forest Department) under the five Ranges (a range has one to several Beats) of the Madhupur Sal forest. Two ethnic minorities (Garo and Koch) have been living all over the Madhupur Sal forest area from time immemorial (Gain 2002). So, the sample population consisted of 60 ethnic and 60 non-ethnic forest dependent people of various ages, ranging from 22 to 65 years. Of the respondents engaged in the case study, about 85% were illiterate and only 10% were female. The majority of the re- spondents (about 63%) were day laborers and subsistence agriculture farmers. Further, this study covered the opinions of four “Range Officers” and the Assistant Conser- vator of Forest (ACF) in Madhupur Sal forest, together with eight scientists working on Sal forests (selection based on their pub- lished books/article/research on Sal forests). The whole study was conducted during the months of July-October 2010, and the case study was conducted in September-October 2010 by a research team consisting of three Fig. 2 - Forest cover map of Bangladesh and the study area.
