(a) Selective exploration: This involves the cutting down of matured trees while allowing the younger ones to reach maturity before they are cut down.
(b) Deforestation: This is the process involved in the cutting down of trees to provide for materials needed by man. Deforestation should be carried out carefully so that the forest or land is not exposed to the agents of erosion.
(c) Regeneration: This is the ability of a plant to easily grow back after it has been cut down. Trees that have the ability to easily grow back when cut can be cut at a faster rate that those that will not easily produce new shoots after they have been cut down.
(d) Afforestation: This is the planting of new trees to replace the ones that have been cut down. This ensures the continuous availability of trees all the time. Afforestation in other words, is the growing of tree seedlings to make a forest.
