Just had another look at my patch. I can see the fields that have been newly-planted with Miscanthus, including one which was only done a few months ago, which still has very patchy growth. That's pretty up to date. The shadows are pointing more or less north, which means the pics were taken around midday, but the shadows are quite long, so, going from the colour of the vegetation, I'm guessing the the pics were updated in the autumn (my location is about fifty degrees north).
