Are lambs counted in ECO Scheme calculations or is it just the ewes counted?
I'm not well up at all on the new scheme however after reading your question and doing a bit of research it appears that the stocking rate for sheep is a lowland mountain ewe (I presume they mean lowland or mountain ewe) and her lamb. You can see from the attached DAFM link "Stocking Rate Calculator" - ** Nitrates figure used is for lowland mountain ewe and lamb.
Don't take my word on it - best check with your Ag advisor.
