When the vegetation of a region reaches climatic climax, it usually becomes
mesophytic
The final or stable community in a sere is called as climax community or climax vegetation. It is self-perpetuating and in equilibrium with the physical habitat. This vegetation is tolerant of environmental conditions. It has a wide diversity of species, a well-drained spatial structure, and complex food chains. Mesophytes are those plants which grow neither in too dry conditions not in too wet conditions. A forest is thus a mesophytic vegetation which is a climax vegetation.
Hydrophytes, lithophytes are the not the climax vegetation and xerophytes become predominant in successions disturbed by human activities which lead to desertification of the land.
