Ramblings ’round Thorne

You’ve heard us say that there’s always new discoveries to be made by people with time, determination and a keen eye.  I’ve just received some stunning images from Barry Warrington a keen amateur naturalist from Hull, along with details of his recent find Cladonia bellidiflora which we understand has been confirmed by Dr Alan Silverside.  This record consitutes (unless anyone else out there knows otherwise) a new species for Thorne Moors SSSI.

Cladonia bellidiflora can be distinguished from C. squamosa (which also has peeling squamoles on the podetia) by the red apothecis, yellow tinge and the KC+ reaction.  See a useful explanation of the use of chemical tests on the British Lichen Society website.

Dobson (2000) comments that it is frequent on soil and peat especially in stabilised scree.  Mainly found in upland areas of Scotland and northern England.  There are no Yorkshire records on his distribution map for the species, neither are there any on NBN Gateway for the species in the county.

Has this species been there all the time and been missed by visiting naturalists or is it a consequence of management practices which haven’t considered or addressed the issue of biosecurity?

Please, keep the records coming as any data adds to our understanding of the changes occuring on the Moors.  It can also help when considering management operations.
