Examples of an Assisted Regeneration Approach
This approach requires both removal of the cause of the damage and active interventions to stimulate recovery. (It is sometimes erroneously included in 'spontaneous regeneration' or 'passive' restoration). It differs from 'natural regeneration' in that, without active intervention, recovery will not occur.
All restoration interventions - including reintroductions - provide starting points for natural recovery. However it is important to ask prior to the start of a project, 'what can be done to trigger any remaining recovery potential?' Sometimes that may be all that is needed to get the process up and running.
Lessons and Limitations
- Adaptive management is always required when applying disturbances as they can lead to unpredictable responses.
- Adaptive management is also needed where the triggers are in the form of resource provision - as undesirable species may also be facilitated.
- Some species may not regenerate and may need reintroduction. Others may regenerate but in too small numbers to maintain genetic diversity.
