Answer:
Ecological succession refers to the changes taken place in a forest over a particular period of time.
Succession is usually influenced by environmental factors such as water regimes, soil type, climate, vegetation history, and invasive species.
Humans interventions affect all of the above-mentioned factors.
Human activities such as fragmentation of forests, clearing of forests for agricultural practices, construction of dams, civilization, logging et cetera drastically reduce the biodiversity of a forest.
This reduction of biodiversity forms the foundation for a secondary succession of a forest.
