FRST 121 : INTRODUCTION TO FORESTRY
Introduction – definitions of basic terms related to forestry, objectives of silviculture, forest classification, salient features of Indian Forest Policies. Forest regeneration, Natural regeneration – natural regeneration from seed and vegetative parts, coppicing, pollarding, root suckers; Artificial regeneration – objectives, choice between natural and artificial regeneration, essential preliminary considerations. Crown classification. Tending operations – weeding, cleaning, thinning – mechanical, ordinary, crown and advance thinning.
Forest mensuration – objectives, diameter measurement, instruments used in diameter measurement; Non instrumental methods of height measurement – shadow and single pole method; Instrumental methods of height measurement – geometric and trigonometric principles, instruments used in height measurement; tree stem form, form factor, form quotient, measurement of volume of felled and standing trees, age determination of trees.
Agroforestry – definitions, importance, criteria of selection of trees in agroforestry, different agroforestry systems prevalent in the country, shifting cultivation, taungya, alley cropping, wind breaks and shelter belts, home gardens. Cultivation practices of two important fast growing tree species of the region.
Identification of tree-species. Diameter measurements using calipers and tape, diameter measurements of forked, buttressed, fluted and leaning trees. Height measurement of standing trees by shadow method, single pole method and hypsometer. Volume measurement of logs using various formulae. Nursery lay out, seed sowing, vegetative propagation techniques. Forest plantations and their management. Visits of nearby forest based industries.
1) Identification of tree-species of the Campus and its classification according to uses and preperation of herbarium
2) Measurements of diameter-girth and basal area of trees using Calipers, Tape, Ruler, Pentaprism Tree Caliper etc
3) Measurement of height using non instrumental method and Instrumental methods like Hypsometer, Ravi Multimeter, Abney level
4) Volme estimation of logs and standing trees using Quarter girth formula
5) Study of Natural regeneration in forest area and mode of regeneration
6) Planning and layout of forest plantations, Choice of species, methods of planting and after care
7) Exercise on tree nursery practice- seed collection, seed pre-treatment, bed preparation and sowing
8) Field exercise on various tending operations in forest/plantations like thining, pruning, climber removal etc.
9) Study of Traditional agroforestry systems in the region and visits to some of the local agroforestry systems and recording its components.
10) Study of Tree Architecture, structure and growth of trees, crown and root architecture
11) Identification of trees suitable for Windbreaks & Shelterbelts, Fodder etc.
12) Visit to forest plantation and study of its growth and general condition of plantation.
