You are correct the PGC assigns no carrying capacity to farmlands just like they don't assign any additional carry capacity to food lots on SGLs, reclaimed strip mines, and right of ways. That is why 5C had a goal of 6 DPSM while 2F had a goal of 17 DPSM. The habitat in 5C was a lot better than in 2F but the PGC refused to acknowledge that fact and that explains why they are managing the herd at such low numbers.
