Abstract: Biological diversity, or biodiversity, is the variety of life. It encompasses the variability among living organisms and includes diversity
within species, among species, and among ecosystems. High biodiversity enables a forest ecosystem to respond to external influences, absorb and recover from disturbances, and still maintain essential ecosystem processes such
as regeneration, nutrient cycling, support of wildlife, and purification of air and water.
