Course Name : Introduction to forestry

Code(Credit) : ASIF(1201) 2(1+1)

Course Objectives

The objective of the course is to Identify the tree species and the uses of NTFP.
Gain knowledge about the choice of tree species for agro forestry purpose.
Estimate the quantity of timber / firewood/NTFP(volume/weight) and other forest resources by using height and volume measuring equipments.
Manage the forest nursery by applying nursery techniques.
Apply the required cultivation practices for different tree species.

Learning Outcomes

To teach the B.Sc(Ag) students about the tree species ,its description and identification by demonstrating them inside the campus.

To make the students aware of the growing stock and the management practices of forest.

To train B.Sc.(Ag) students about the scientific management of forest trees with the crop, on the same unit of land under the agro forestry system.

To teach the student about the estimation of height of the tree, bark thickness and quantity of timber / firewood/NTFP(volume/weight) and other forest resources.
