The ecological experiment is natural based, as their name suggests, are not controlled by anyone. These are natural disturbance to an environment. The ecosystem itself is an experiment, for instance, following a natural disaster, a shift in the climate, or the introduction of exotic species.
Disturbances are significant natural forces that shape the dynamics of forest ecosystems and significantly influence their composition and functionality. As a result, shifting disturbance patterns may significantly affect forest ecosystems, potentially having long-lasting effects on their biological richness and ability to deliver ecosystem services to the general public.
Ecosystem management necessitates a thorough comprehension of the effects of natural disturbances in order to offer ecosystem services to society while promoting biodiversity.
