Appendix 7a of the Environmental Assessment lists all the sites of cultural importance that might be affected, dozens and dozens of them, which rather points up the fact you can't build anything in Britain without destroying something, so it's important not to be in the position of picking out a single case - unless it's head and shoulders more important than others or you're going to say you're against all development - the forces of smashing things up win hands down as they can dismiss modern antiquarians as cranks. Ask Tarmac et al.
Anyhow, in this case there are two possible bronze age round barrow cemeteries mentioned (129 and 146) (Do they mean barrow cemeteries or barrows?) So if they're only "possible" and therefore not scheduled I wouldn't think there's a big chance of getting them protected. The Rotherwas Ribbon wasn't "possible" it was all too real and a thousand times more important and the road that was allowed to be built over it was a thousand times less needed....
