Map lichen Rhizocarpon geographicum, seen here growing on Ordovician siltstone at the summit of Gyrn Wigau in Snowdonia, Wales, is commonly found in the west of the British Isles. Lichens are composite organisms of fungi and algae existing in a symbiotic relationship and are among the oldest living things on earth. They are sensitive to atmospheric pollution and are therefore good indicators of air quality.
Landscape photography is my focus (sic) since retiring from a university career researching and teaching plant and environmental science. Photography combines my lifelong love of Britain's wild places with an understanding (I hope!) of how our diverse environments work and the processes within them, as well as the way light falls on them. Seeing - really seeing - what is around us is hard, and the challenge for me is to find formalist images whose structure and atmosphere are consonant with the nature of the subject.
