Biodiversity enhancement


Ecological enhancement measures are those that actually improve the ecological condition of the development site (or an alternative site) after the development is complete. Ecological enhancement measures must, therefore, be over and above any avoidance, mitigation and compensation measures required to neutralise the impacts of the development on wildlife. Developments that provide ecological enhancements should be looked upon more favourably by the local planning authority.

The law, central government planning policy and, increasingly, local planning policy, now point towards the enhancement of biodiversity as part of the development process. This really means including features for biodiversity within the development design that are over and above the measures taken to neutralise the negative impacts of the development. Features that are increasingly being included in development designs as measures to enhance site biodiversity include:

An alternative to including biodiversity features within the design of the new development may be to finance the enhancement of a nearby site of nature conservation interest or even the creation of new habitats on land of low current ecological value.
