Forestry Syllabus for IFS

You must be well familiar with both the material and the exam pattern to devise an effective preparation approach. There are two optional subjects in the IFoS mains, each with four papers.

Each document is broken into two parts: Part A and Part B. The papers have a total of 8 questions, four in each portion. Only five of these eight questions must be answered by both parties. Part A’s question 1 and Part B’s question 5 are both required. Aside from this, you must attempt two more from each section. Any of the sections can be used to answer the fifth question.

Forestry Optional Subject for Indian Forest Service

Even though that forestry is not necessarily a subject of specialisation for many candidates, many who have related disciplines in their undergraduate degrees pursue it.

Forestry is a good alternative for those who are interested in agriculture, gardening, or botany. Here are some of the benefits that make it a good option for many candidates:

#There isn’t a lot of factual data on this subject, therefore you won’t have to memorise a lot of dates and events. Many candidates find the subject simple to comprehend and study primarily for that reason.

#If you can remember the botanical names of different trees and back up your answer with good diagrams, this is a very high-scoring subject.

Paper-1, Forestry Optional Syllabus

One and Two

General silviculture

The greatest source for this chapter is L.S. Khanna’s book.

To get the most points, use as many examples as possible while composing the answers to this chapter’s questions.

This is the most crucial chapter in paper 1, so devote as much time as possible to its preparation and go over the questions from prior years several times.

Silviculture system

This, like the previous chapter, is a fundamental forestry chapter that necessitates a large amount of effort and attention to prepare the themes.

Because questions are frequently repeated, reviewing past years’ papers will be beneficial.

Forest engineering and surveying

This is another technical issue that can be difficult to grasp if you are unfamiliar with the principles.

Wikipedia is a wonderful place to start if you want to study the basics of the chapter.

It is not as critical, but having a basic understanding will allow you to attempt any questions posed from this point forward.

Reference Books for Forestry Optional
