Each tree has asserted itself in its respective strata, i.e., ensuring a vital space for energy (light, mineral salts) and water. In primary forest, competition obviously still takes place, particularly when climatic conditions prove difficult, bringing about a difference in vigour between individuals of the same species (thus in relative diameter). c) A period of maturity ... d) A period of senescence ...
