Lichens in churchyards
Ivan Pedley follows up his November 2016 lecture.
An excellent meeting with 14 members attending. The weather was also excellent, dry with some sun and a temperature of 21C. A considerable number of lichens were seen and it was interesting to note the difference both in numbers and species that occur on different substrates, basic materials especially limestone exhibiting the most. Also present were granite, and slate, both Welsh and Leicester (Swithland) which carried very few species.
Other organisms noted were fox and cubs, green woodpeckers, a colony of Speckled Bush Crickets (new for our records) and some five species of plant gall.
