In the absence of the natural dynamism previously associated with the creation of new dune habitats there are only two practical options: to allow the systems to stabilise and mature and accept the inevitable losses of biodiversity associated with that process, or to introduce a rejuvenation program. Rejuvenation programmes can operate locally within a dune system, targeting discrete habitat patches, or to destabilise parts of the system in an attempt to kickstart the dynamic processes again. On the dune systems bordering the Bristol Channel, the targeted rejuvenation of carefully selected dune slacks has proved far more successful than attempts to kickstart natural processes.
