Setting objectives and defining outputs for ecological restoration and habitat creation

The past 40 years have seen the legal and policy framework for nature conservation in Britain extend from protection and preservation to include enhancement through techniques such as ecological restoration and habitat creation. Clear objectives need to be set for ecological restoration and habitat creation schemes because the processes involve human intervention in combination with natural factors operating over time. Objectives are required for both management and monitoring in order to enable measurement of success or failure. The most effective way to achieve high-quality restoration and creation schemes is to define the output of the process-a habitat, vegetation type, or biological community. The better the definition of the output, the greater the need to define the inputs and the nature of the intervening processes. Ecologists and environmental managers have a key role to play in establishing the degree of definition necessary in order to achieve a particular objective.
