That is not my reading of Hey and Lacey - the key quote from that publication is 'there can be no blanket solution' to evaluation. T'would be very easy and tempting to say 'oh just do 5% trenching' on all rural sites. When dealing with large sites a suite of techniques is often more appropriate. More a point of departure than a manual, I would suggest reading Appendix 2.
