A Concept of Forest Ecosystem Stability and of Acid Deposition as Driving Force for Destabilization the ecosystem. Under the assumption that the ecosystem tends to minimize net proton production or consumption in order to keep the chemical soil state in optimal conditions for growth, the characteristic features of stable forest ecosystems showing high resilience are deduced. A sequence of ecosyst
