It's a mix, a lot of light hedge with some thicker bits from the trees. Not many big enough to really need a saw though. I didn't take a good look at ground level.
Not recent but see https://www.google.co.uk/maps/@55.9744942,-3.2410087,3a,75y,123.44h,79.39t/data=!3m6!1e1!3m4!1suw9BCG55YChaYPZSVQ4imA!2e0!7i16384!8i8192
And the hedge at the bottom is massively overreaching now too: https://www.google.co.uk/maps/@55.9807534,-3.236846,3a,15y,211.24h,88.45t/data=!3m6!1e1!3m4!1sNqWNr5cuOj1u1zrjR25WqQ!2e0!7i16384!8i8192
I've got a split shaft strimmer / hedge trimmer / polesaw type thing (electric, not petrol). Will bring a rake and spare gloves / glasses in case anyone else can rock up.
