Dead time of year?
On a dank, dark day in the depths of Winter it can be hard to believe that there's any colour out there to see in Nature. I've recently been introduced to the beauty of tree bark which is easy to overlook. For any fellow newbie fans out there here's a rather lovely downloadable PDF file with of lots of different colours and textures which might help you identify a few. This is the work of Phil Barnett http://abcissa-websites.co.uk/download/bark.pdf and the fellow in the photo is my barking mad chum A who always adds a bit of sparkle to any get together!
