British NVC community SD1, the only shingle community in the British National Vegetation Classification system.
Major restructuring of BL following the Ryder Report resulted in the SD1 production line being moved to the former Morris plant in Cowley in 1981.
A stable situation existed from thereon, with new models such as the Discovery debuting in 1989, and the Freelander in 1998 - which finally made use of the old SD1 assembly hall.
