Forest can be regenerated both by natural and artificial means.They are:
Artificial regeneration : It consists of afforestation means and reforestation. Under afforestation, a forest is established by artificial means over an area from which forest vegetation has always or long been absent. Likewise, under reforestation, artificial restocking of forest area from where a tree crop has been recently removed is performed.
Natural regeneration : It includes minimization of exposure of soil, economy of labour, permitting the great extension of regeneration area in good seeding year, genetic improvement through the survival of only rigorous seeding out of large numbers, reduced risk of damage from natural causes including pests and diseases, maintenance of natural mixed type,etc.For natural regeneration, there should also be adequate supply of seed, light condition, required density,etc.
