In ecology, climax community, or climatic climax community, is a historic term that expressed a biological community of plants, animals, and fungi which, through the process of ecological succession the development of vegetation in an area over time, had reached a steady state. This equilibrium was thought to occur because the climax community is composed of species best adapted to average conditions in that area. The term is sometimes also applied in soil development. Nevertheless, it has been found that a "steady state" is more apparent than real, particularly if long-enough periods of time are taken into consideration. Notwithstanding, it remains a useful concept.
