The document discusses forest cover monitoring and mapping changes in Chunati Wildlife Sanctuary using GIS and remote sensing. It aims to inventory and map the spatial distribution of forests in the sanctuary, prepare a forest cover map showing the present status, and explore forest cover changes from 1990-2012. Field visits and ground truthing were conducted in Chunati Beat to collect location data. Satellite images from 1990, 1998, 2010 and 2014 were analyzed in GIS to detect land use and forest cover changes over time. The results identified different forest characteristics and mapped the current forest cover and changing patterns in Chunati Beat within the sanctuary.

2. Every country needs 25 % of forest cover of the total area.
The total forest cover of Bangladesh is 9.18 %.
( Forest department,Bangladesh,2014)
Bangladesh has 871000 hectors which is 8 of the total area.
(FAO Report,2005)
In Bangladesh, annual depletion of the growing stock stands at
1.65 % while a large portion of this forest land has been
encroached.
( FCC- Progress Report, Anon 1992)
BACKGROUND OF THE STUDY

3. Aim of the research
Forest cover change and monitoring of Chuanti Wildlife Sanctuary
(Chunati beat) in order to detect the present status of forest cover.

4. Objectives of research:
To inventory and mapping of spatial distribution of forest.
Prepare a forest cover map showing the present status of forest cover.
To explore forest cover change detection ( 1990-2012)
Research Questions
What types of forest covers are extent in the spatial distribution of
forest ?
What are the present types of forest cover extent ?
What extent of forest cover changes occurred ( 1990-2012) ?
