Planning Policy Guidance note 17: “Planning for open space, sport and recreation” (PPG17) already encourages local planning authorities to identify the specific needs for easily accessible, good quality open space, including woodland, within their areas. Authorities should use the information gained from their assessments of needs to establish an effective open space strategy which should form the basis for appropriate policies in their development plan. PPG17 requires local authorities to derive local standards for the provision of open space, as national standards cannot cater for local circumstances, such as the extent of existing built development in an area.
