When I was on Exmoor earlier in the week I encountered a couple of wildlife highlights
This is the lichen Lobaria virens – it is one of the species of of lungworts found in Britain. It is a rare and special organism. Lungworts need very pure air in which to grow – they also need an Atlantic climate and flourish in shady, damp places in upland woodlands on the western side of Britain. I photographed this specimen in Horner Woods – a fantastic woodland near Porlock.
This is the distribution map of Lobaria virens produced by the British Lichen Society – see here for more details. The red dots represent records of the lichen since 2000, blue dots records from 1960-1999 and the yellow dots are pre 1960 records. As you can see if it very rare and declining but Exmoor and Dartmoor are important strongholds for it.
