About Clements' distinction between primary succession and secondary succession, Cowles wrote (1911): This classification seems not to be of fundamental value, since it separates such closely related phenomena as those of erosion and deposition, and it places together such unlike things as human agencies and the subsidence of land. Ponds are shallow holes where water collects. Primary succession is characterized by a total loss of biomass and soil from the ecosystem or a beginning lack thereof. Each transitional community that is formed and replaced during succession is called a stage in succession or a seral community.
