Definition of ecological restoration
In 2004, the Society of Ecological Restoration defined ecological restoration as “the process of assisting the recovery of an ecosystem that has been degraded, damaged or destroyed.”Ecological restoration makes a substantial contribution to the ‘greening’ of the planet through Ecological Engineering (the management of nature) or Ecotechnology (the transfer of ecological principles into ecological management). Restoration ecologist attempts the disturbed ecosystem to reassemble it, to repair it and to adjust it so that it works properly.
Restoration goal
The goal of restoration ecology is the restoration of a degraded ecosystem to their natural condition or the creation of a new ecosystem to replace the one that was lost.Restoration has been called the ‘acid test’ of ecology because of the substantial challenge it
represent.
Restoration approaches
Restoration is the process of rebuilding a degraded ecosystem. Ecological restoration is an intentional activity that initiates or accelerates recovery of an ecosystem with respect to its function (processes), integrity (species composition and community structure) and sustainability (resistance to disturbance and resilience). It enables abiotic support from the physical environment, suitable flows and exchanges of organisms and materials with the surrounding landscape and the reestablishment of cultural interactions upon which the integrity of some ecosystems depends.It may have 3 – approaches:
Re-vegetation – re-establish the vegetation cover.
Reclamation – making the ecosystem more habitable to wildlife.
Rehabilitation – rebuilding essential structures and functions of degraded ecosystems.
Ecological restoration re-initiates ecological processes. The restored ecosystem in the course of time self-organizes and becomes increasingly self-sustaining. Restoration ecology and conservation ecology are related because the restored ecosystems provide habitat for species threatened by human impacts.
Restoration components
Generally this can involve many different elements,
depending on the ecosystem and the degradation that has occurred. Essentially
the process needs attention of 3 aspects:
1. Re-modelling the physical aspects of the habitat;
2. Re-modelling the chemical aspects, nutrients and toxicity; and
3. Replacing missing species or removing undesirable exotics.
