One of the grandest avenues of trees in London is the elm avenue in Kensington Gardens which marks the grand finale of this creative photography walkshop (walking workshop) to mark National Tree Week (26 Nov - 4 Dec 2016).  Join Peter Coles, urban nature writer and photographer, as we go stalking elm in Marylebone, Mayfair and Hyde Park.  Our walking route, may well be determined by the shape and structure of trees as their branches become visible, now their leaves have fallen.  This time of year, is often the best time to capture trees photographs, as their branches and trunks  stand out starkly against wintery skies.
