Reindeer lichen  (Cladonia mediterranea)

The remaining populations of this lichen in the UK are very small; this makes them highly vulnerable (1). Possible threats are trampling by livestock and the public, and fires (2).

The sites on Lizard Peninsula occur in a National Nature Reserve (1). Cladonia mediterranea is a UK Biodiversity Action Plan Priority Species. The Species Action Plan aims to maintain and where possible, enhance all current populations. Work is needed to elucidate the taxonomic status of the species in the UK (1).
