South Gloucestershire LPA BNG

South Gloucestershire runs from the tidal Severn on its north-western edge, across a coastal plain and the River Frome valley, to the Cotswold escarpment on its eastern side, with the western half mainly urbanised around the northern edge of Bristol. The Frome rises in Dodington Park near Chipping Sodbury and runs through Yate, Frampton Cotterell and Winterbourne. Lower Woods near Wickwar, a 280-hectare SSSI managed by the Gloucestershire Wildlife Trust, is the most extensive area of ancient woodland in the former county of Avon, and Dyrham Park on the Cotswold edge is a National Trust deer park. According to the council’s 2022 draft biodiversity SPD, the district has 22 SSSIs, 271 Sites of Nature Conservation Interest, 11 local nature reserves and one European site, the Severn Estuary.

​

Biodiversity Net Gain became a legal requirement for major developments in England on 12 February 2024, and for small sites on 2 April 2024. The council consulted in July 2022 on a draft Biodiversity and Planning SPD, which encouraged a minimum 10% gain and set out a sequence for sites that cannot deliver on site: commuted sums paid to the council, third-party habitat brokers, offset land bought by the applicant, and statutory credits as a last resort. The council’s new Local Plan was submitted to the Secretary of State on 27 October 2025 and is still under examination, with adoption expected in 2027 or 2028.

​

The practical constraint is room. The western half of the district is mainly urbanised and Green Belt protections apply around it, so urban-fringe schemes have less space for on-site habitat and the council’s off-site sequence matters. The draft SPD lists the habitats that count locally, including traditional orchards, hay meadows, wood pasture and parkland, and the saltmarsh and intertidal flats of the Severn Estuary. South Gloucestershire does not appear in Natural England’s nutrient neutrality catchment tables.
