Developers should ensure new housing developments result in:

* Retention of key wildlife sites - better protection of the already diminished wildlife resource.

* More space for wildlife - a substantial increase in the creation and restoration of habitats, through additional funding and resources, for example Section 106 agreements and conservation covenants - contributing to an overall increase in the abundance and diversity of wildlife and an improvement of soil and catchment health.

* Improved connectivity of wildlife habitats - both within developments and linking to the wider landscape and ecological networks beyond.

* More than compensating for any habitat that is lost - where damage to existing habitats is unavoidable, mitigation must bring about an overall gain in habitats. This should be assessed objectively using an improved version of the Defra biodiversity metric.

* Creating new habitat - habitat creation should be a standard feature of all new housing development, wherever it is.

* Ensuring our natural spaces are well managed for posterity - maintaining local green spaces is as essential as maintaining roads, power and other important infrastructure. Financial planning should account for this at the outset, through a service charge or capital endowment.
