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

Aim of the researchForest cover change and monitoring of Chuanti Wildlife Sanctuary

(Chunati beat) in order to detect the present status of forest cover.

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) ?
