For example, when larger species like trees mature, they produce shade on to the developing forest floor that tends to exclude light-requiring species. Ecological succession describes changes that occur in a community over time. forest Pioneer species are important in ecological succession. The oldest stage of succession shown in the figure is: Oldest Stage Of Succession Shown In The Figure Above. Two important perturbation factors today are human actions and climatic change.[13].
