Apparently the 12 OWD in 2003 was the actual number of OWD and not the minimum. So it is pretty obvious hat they reduced the herd in 2G from the goal of 15 DPSM to 8 r 9 OWD PSM in 2006. Therefore, it is also obvious that the habitat in 2G can support more than 15 DPSM ,since breeding rates and productivity didn't increase as the herd was reduced.
