The photos show the same area on July 2015, just before I took over the tenancy of Plot 248, and in February 2016, after I had done some clearance work. It is difficult to see that it is the same area but on the July photo you can see the post covered in chicken wire on the right, and just about make out the gable end of the shed in the top left of the photo.
Having roughly levelled the area I covered it with thick cardboard and wood chippings to try to kill off weeds. I am sure I will have to trowel out some shoots of nettles and brambles. Access to the back of the plots will now be possible for me and my neighbours.
