Thames Basin Heaths Special Protection Areas Avoidance Strategy
In March 2005, the Thames Basin Heaths Special Protection Area (SPA) was classified under the EC Birds Directive. It includes areas of heathland across Surrey, Hampshire and Berkshire, covering 11 different local authorities, including Woking. The sites in Woking Borough are parts of Horsell Common, Sheets Heath and Brookwood Heath.
The SPA has been identified as an internationally important breeding habitat for three rare species of bird - the Dartford warbler, woodlark and nightjar.
Natural England has demonstrated that the new population arising from housing developments at a distance of up to 5km from this SPA can cause significant disturbance to the breeding success of these rare bird populations, due to the impact of residents recreational activities, particularly walking and walking with dogs. As a result, all housing developments within 5km of the SPA will now be subject to stringent tests and impact assessments.
As a statutory consultee on planning applications within 5km of an SPA, Natural England has the right to object to applications which it considers will have a negative impact on an SPA. However, it has established that impacts on the SPA can be avoided through the provision of suitable alternative natural greenspaces to divert recreational pressure away from the SPA. These alternative greenspaces can either be new or improved existing greenspaces.
Natural England has produced standards for the provision of suitable alternative natural greenspaces and Woking Borough Council has applied these to produce a strategy to enable housing developments to continue. In producing this Strategy officers have worked closely with Natural England.

Thames Basin Heaths Special Protection Area Avoidance Strategy SPD 2026
The Thames Basin Heaths Special Protection Area Avoidance strategy SPD was adopted by the Council on 22 January 2026 and is a material consideration in the determination of planning applications. This SPD replaces the previous version of the SPD, adopted in 2022. The Avoidance Strategy ensures that the Council takes appropriate and necessary steps to avoid harm to the SPAs and that developers are fully aware and informed of their duty to mitigate the effects of their development on the SPAs. The SPD will help meet the protected bird targets and increase biodiversity across the Borough.
The Avoidance Strategy contains an overview map of the Borough. A large detailed map of the Borough can be downloaded which shows individual dwellings.
In order to avoid harm to the SPA planning applications for residential development are expected to financially contribute towards works to improve existing greenspaces within the Borough.

Strategic Access Management and Monitoring (SAMM)
The SAMM tariff is a separate payment from CIL which is secured by a S106 Agreement. The SAMM tariff is indexed linked year on year. The following table demonstrates the tariff as of 1 April 2025 - 31 March 2026.
Joint Strategic Partnership Board
The Joint Strategic Partnership Board (made up of relevant local authorities, Natural England, Homebuilders Federation, RSPB, Open Spaces Society and Wildlife Trusts) has produced a Delivery Framework. Each affected authority has adopted the framework which details the introduction of SPA access management measures to inform visitors about the impacts their visits are having on rare birds, to encourage changes in behaviour.
