Nature's Alphabet

Working to a theme of 'Natural Alphabet' for one of my Flickr Groups this week, I went for a stroll through Haigh Hall Country Park and managed to find the following letters.
Some are repeated, and since I was particularly looking for J O H and N, I've probably missed loads of other letters .
