He held that within any given region of climate, ecological communities tended to slowly converge toward a single endpoint, which he called the "climatic climax."

Clements even thought that the process of ecological succession—the replacement of some species by others over time—was somewhat akin to the development of an organism, from embryo to adult. Clements thought that succession represented discrete stages in the development of the community(rather like infancy, childhood, and adolescence), terminating in the climatic "adult" stage, when the community became self-reproducing and succession ceased. Clementss view of the ecological community reflected the notion of a precise balance of nature.
