  6 March 2020: (Yes the last weeks of freedom in UK before COVID)
Join us as we walk down May Beck on the  The British Lichen Society's field day on 6 March 2020  in the North Yorkshire Moors  We are joined by a group from Whitby Naturalists
    Yorkshire had repeated record breaking repeating floods all the previous month. Now on the third fine day in a row,  we rejoice the ground is beginning to dry out a little.  
    On the 7th and 8th March (2020) we will be indoors at Cober Hill  enjoying the good food there and sharing of lichen ideas.
    Little do we know that within a fortnight the UK will be in lock-down due to Coronavirus
  


This is the fourth year the British Lichen Society has had a workshop at Cober Hill, Cloughton, near Scarborough.

The first year was an autumn field trip. In 2018, 2019 and this March 2020 were workshops where we brought specimens in ourselves.

We are joined by a bunch from Whitby Naturalists .. some of whom detour in the afternoon to count frogs elsewhere.

There is plenty to see on the big sandstone boulders in the car park

Porpidia platycarpoides
Lecidella stigmatea

On the Saturday and Sunday we spend time in the workroom at Cober Hill helping each other with specimens that had been puzzling us over the year.  Thanks especially to Neil Sanderson and Brian Coppins for helping us.



On the way home I stop at a tree near the road near Hackness to the north of the Forge Valley. Over the road was Crossdales Beck, which shortly joined the River Derwent. The river Derwent and the river Aire which starts near Malham Tarn 80 miles to the east both flow into the Ouse. (This observation kinks in with other flooding items on this blog)

On the tree is Calicium viride.  It is VERY tiny. It is a pinhead lichen.




Calicium viride. 


I return home with renewed enthusiasm to continue studying my home hectad SD 86 which I started after last year's Lichen workshop...

And lots of opportunity to study the trees near where I live in exercise walks, in the five weeks before the leaves come on the trees and hide them!

Do visit the The British Lichen Society Website. Many of the events which were planned for this year (2020) will be held next year...
