More about this guideline
With avoidance, biodiversity impact minimisation is the other preventative stage of the mitigation hierarchy. It refers to the measures taken to reduce impacts (including direct, indirect, and cumulative impacts, as appropriate) that cannot be completely avoided, as far as is practically feasible.
Whereas avoidance removes the potential of project impact by positioning or timing of the impact activity, minimisation acts to reduce the severity (through its extent, intensity, or duration) of an impact. There are three types of minimisation actions (often termed ‘controls’) that are generally used by industry (CSBI, 2015). These are:
In some situations, minimisation measures can be implemented early on in the project before the disturbance occurs, thus enhancing the chances for successful implementation of mitigation measures, and in particular the amount of residual impacts after avoidance, minimisation, and restoration of impacts.
