ABSTRACT

Vegetation is hardly stable and thus dynamic, changing over time and space due to variations in climatic and physiographic factors and the activities of the species of the communities themselves. Succession is a natural process by which different groups or communities colonize the same area over a period of time in a definite sequence or it is an orderly process of community development that involves changes in species structure and community processes with time and it is reasonably directional and therefore predictable. The various types of succession have been grouped in different ways on the basis of different aspects. The monoclimax theory allows for only one climax community in a region, the polyclimax theory allows several climaxes and the climax-pattern hypothesis allows a continuity of climax types varying gradually along environmental gradients and not clearly separable into discrete climax types.
