Some of the less disturbed areas of acid grassland will still support clubmosses, like the stag’s horn clubmoss (Lycopodium clavatum) – seen here in association with heath bedstraw (Galium saxatile) which a common component of acid grassland. However, this clubmoss has been identified by Plantlife as one of a priority species for conservation in the UK. It is a species that cannot tolerate disturbance, burning or intensive grazing.
