About Me

My photo

I have been interested in nature for most of my life but since I retired I spend as much time as I can exploring the nature reserves and wildlife hotspots of my adopted home, Dorset in southern England. Whilst out I record what I see and take snaps where I can (I am no photographer!) and that forms the basis of my Nature of Dorset website. When I find something new I like to research it and write about it in my nature notes, it is how I learn and hopefully you might find my notes helpful as well!

This website is for the people of Dorset interested in wildlife and for people from elsewhere interested in the wildlife of Dorset!

Many years ago I was anxious to find out more about lichens and so I bought the definitive guide to British lichens written by the all time specialist in the subject, Frank Dobson (the book is called 'Lichens: An Illustrated Guide'). This is part of what it says about Parmelia sulcata:
"Thallus orbicular, grey to glaucous-white. consisting of overlapped ridged and sinuate lobes, normally covered with a faint white reticulum along which soralia develops, these may spread and cover the centre of the thallus. Under surface very dark brown with black rhizinae. Apotheccia with a dark brown disc. Distinguished from P saxatillis by the presence of soralia as opposed to isidia."
I have never mastered lichen in twenty plus years of trying and above is the reason why!
