The climax-pattern theory states that not only climate, but several other factors, determine the characteristics of the climax community.
Unlike, monoclimax and polyclimax theories which state that climate is the only determining factor, climax-pattern theory states that characters of the climax communities are determined by the total environment of the ecosystem not only by single factor.
According to climax-pattern theory, there are more climax communities that are continuous and varying gradually along environmental gradients.
