Biodiversity Net Gain in Winchester Local Planning Authority

Winchester, located in Hampshire, is a predominantly rural district authority that includes the historic city of Winchester along with surrounding towns, villages, and extensive countryside. Covering approximately 450 square kilometres, the area features a mix of urban areas, agricultural land, woodlands, and chalk downlands.
Aligned with the Environment Act 2021, Winchester City Council requires most development projects to deliver a minimum of 10% Biodiversity Net Gain (BNG). This can be achieved through on-site habitat creation or enhancement, off-site biodiversity units, or contributions to local and strategic ecological networks.
The LPA lies largely within the South Downs and the Hampshire Downs National Character Areas, supporting habitats such as chalk grasslands, ancient and secondary woodlands, rivers, and wet meadows.
The diverse landscape presents significant opportunities for BNG through habitat restoration, woodland management, chalk grassland enhancement, and wetland creation.
For developers, landowners, and planning professionals working in Winchester, understanding local habitats, planning policies, and biodiversity priorities is essential. Our team offers detailed BNG assessments, habitat surveys, and ecological consultancy.

Winchester BNG Planning
High distinctiveness habitats such as chalk grasslands, ancient woodlands, and chalk streams are central to achieving meaningful biodiversity net gain and require careful protection.
Lower distinctiveness habitats like improved grassland and secondary woodland offer additional opportunities for habitat enhancement.
