1. High Forest System

2. Clear Felling System The clear felling system is defined as a silvicultural system in which equal or equi - productive areas of mature crop are successively clear-felled in one operation to be regenerated most frequently, artificially but sometimes naturally also. The area to be clear-felled each year in uniformly productive sites is l/n of the total area allotted to this system’s . Where n = no of years in the rotation and is usually referred to annual coupe. The regenerated crop is absolutely even aged. The coupes to be felled every year are made equi -productive

3. Clear Strip System A silvicultural system in which clear-felling is done in the form of strips which progress successively in one direction across the regeneration area. It is also known as progressive strip system.

4. Alternate Strip System The Alternate-strip system may be defined as a silvicultural system in which clear felling is done in the form of strips, and the clear-felled strips alternate with unfilled strips of similar width, though sometimes these may be narrower or wider also..
