Question

In the Northeast region of India, during the process of Jhum cultivation, the forests are cleared by burning and left for regrowth after a year of cultivation. How would you explain the regrowth of forest in the ecological term?

Accepted Answer

Ecological succession refers to the natural development of a series of biotic communities in an area, one after the other, in the same area until a permanent stable community is established. It is an orderly replacement of animals and plants communities with new ones. The first community that appears in such area is called the pioneer community. The different stages after this stage in this succession are called sere and the last, stable and the highly diverse stage is called the climax community.

In Jhum cultivation, the whole vegetation is set on fire after the harvest so that the ash that gets formed makes the soil fertile. Therefore, an area that has been destroyed by human activities like fire, makes the land barren. The life that existed earlier gets destroyed. A succession can restart again by the development of the pioneer community and this type of succession is called secondary succession.
