Regional supply commentary

Strong supply in lowland mixed deciduous woodland and species-rich grassland; chalk grassland units are pinch-point. None of these operators publishes a per-unit price; units are sold by quote. Check registered supply on the Defra biodiversity gain sites register, then ask operators to quote.[S5]

Trading-rule and spatial-risk note

Off-site units sourced inside the LPA carry the 1.0 spatial multiplier; neighbouring NCA discounts to 0.75; outside NCA discounts to 0.5. Combine with the like-for-like trading rule when triangulating compliant supply.
