Not sure if this has been been covered elsewhere already, but I was surprised to see what appear to be grave markers (wooden crosses) dotted across the corner of the old Nursery land (by the far end of the platform) at Honor Oak Park?

Are they actually old graves that have been uncovered after clearing the woodland or something else (my understanding from reading the previous applications to extend the cemetary was that neither the Park nor Nursery had been previously used for burial plots)?
