It's a step in the right direction, now it's important that at the very least nothing bigger than sheep are ever in the field, it really needs buying up by the NT and just mowing now and again and very soon you'd have lovely rare wild flowers growing in the field within a few years and all the others creatures that would bring, i must say up in Scotland they're very good at mowing grass at the looked after ancient sites, they even do the Clava cairns every couple of weeks in the summer to keep it nice, now that's a job eh, gardening and keeping tidy Ancient sites, there should be teams out there to look after them and do the gardening, i can think of a few people on here [myself included] that would love to do that if it was a real job, in fact it would be the best job in the world, shame it doesn't exist.
