Ecological Restoration: Defining the Goal

Ecological restoration involves assisting the recovery of degraded ecosystems. The process aims to repair damage and improve the ecosystem's health.

The defined endpoint for this process is when the ecosystem:

This endpoint emphasizes the removal of negative anthropogenic impacts or unnatural stresses that caused the degradation. The ecosystem is considered restored when these detrimental influences cease.

Analysis of Alternatives:

• Option 3 (Structure and functions restored): While crucial, restoring structure and function is often the mechanism or a concurrent result of becoming disturbance-free, not the final definition itself in this context.
• Option 4 (Provides some ecosystem services): Providing services is an outcome and indicator of recovery, but the primary goal is the ecological state free from damaging disturbances.
• Option 1 (Pollution-free, solace): This option includes subjective and human-centric elements (solace) and is broader than the core ecological definition focusing on disturbance elimination.

Therefore, achieving a state free from harmful disturbance is presented as the defining criterion for completing ecological restoration.
