Site constraints 7

Special area of conservation: Dorset Heaths

3 designations overlap here. A habitats assessment is needed.

Harm to a protected site is only accepted where there is no alternative and an overriding public interest.

SSSI: Winfrith Heath SSSI

Natural England must be consulted on work that may affect it.

Sites of special scientific interest are the best wildlife and geological sites in the country. Development likely to harm one is rarely permitted.

Nutrient neutrality catchment: Poole Harbour SPA/Ramsar

New homes and overnight accommodation must show nutrient neutrality before approval.

Natural England advice: extra wastewater in these catchments harms protected habitats, so schemes must offset their nutrient load, usually through credits.

Priority habitat: Lowland heathland

A habitat of principal importance. It shapes the ecology work and the biodiversity net gain a scheme has to show.

Agricultural land, grade 3b

Not best and most versatile land (grades 1, 2 and 3a). Source: the Predictive Agricultural Land Classification Map (Defra and Natural England, 2025; the Welsh Government's Predictive ALC Map 2 in Wales), a model rather than a site survey. Natural England's Provisional ALC map (1:250,000, 1970s) agrees.

Where development of farmland is needed, policy prefers poorer land over the best and most versatile (grades 1, 2 and 3a). Three sources: Natural England's post-1988 field surveys, which are definitive where they exist; the Defra predictive map for England (2025) and the Welsh Government predictive map, modelled from the soil map with 3a and 3b split; and the 1970s provisional map, which planners and other services still show, coarser and with grade 3 undivided. Where the provisional and predicted grades disagree, treat the predicted grade as the current estimate and expect an application to carry its own survey.

Habitat network: Lowland heathland

Where habitat is joined up enough to work as a network. Context, not a constraint on its own.

Also on the record

Nature improvement area: Wild Purbeck.

Not affected

Outside flood zones 2 and 3 · Not green belt · No listed building at the site

Checked on 6 October 2026. Historic England, the Environment Agency, Natural England and council datasets, Open Government Licence. A boundary can run through a site and the council holds the definitive record: confirm with the council before relying on this.
