Ecosystem Preservation and Conservation Strategies
Ecological Restoration
It is a process of assisting the recovery of an ecosystem that has been partially or completely degraded. In simple words ecological restoration means restoring the ecosystem, to a former state or to an perfect condition. Ecological restoration focuses on the recovery of many aspects of ecosystem which are as following.
- Integrity of ecosystem: Species composition and community structure
- Health of the ecosystem: purification of air, sequestration of carbon dioxide, filtration of water
- Sustainability: Resistance and resilience to disturbance
Rehabilitation
It mean returning of a degraded land to a fully functional ecosystem irrespective of its original state but according to a prior landuse plan. Examples of the rehabilitation process are partial recovery of species diversity and ecological complexity, reducing the livestock grazing from riparian zone, allowing natural growth of vegetation or restoring fluvial processes.
Remediation
It is a process in which using physical and biological methods, chemical contaminants are cleaned from polluted ecosystem in order to protect human and ecosystem health.
Reclamation
It is a process by which biotic function and productivity of severely damaged land is restored.
Mitigation
It is defined as restoration, rehabilitation or reclamation process to reduce the effect of the source of degradation.
