The forests which is being clear cut will be disturbed. The animals and birds species will migrate to different location in search of food and habitat. The clear cut forests can be restored as the soil is fertile enough to support the growth of new plants. The colonization of new plants will take place with the already present precursors like seeds, roots and partially trees. The animals and birds species will soon immigrate after colonization of tree and plants species. Therefore, the ecosystem will repair itself with the help of these precursors.
