I think the economic drivers that have taken native range and converted it to cropping systems have largely taken place. There is a bit more that could take place given the recent pressures with bio-fuel production demands here and in the US, but lets be realistic. This conversion is likely to take place in the areas linked to irrigation, where margins can be reached via specialty crops and these are in localized pockets not within the pilot project's scope.
The areas in question (wmu 108 & 300) contain large land holding ranches and areas that likely would be less susceptible to the wholesale conversion to agriculture. They do graze cattle, so you could argue that the quality of the grazing could be impacted, but the habitat is already maintained. I am of the opinion that retention of habitat is somewhat of a misnomer. Several farming cycles have pretty much converted most of the "economic" habitat at this point anyway (how else would you have hutterites eligible for RAMP payments).
In wmu 300 there are grazing leases that are well utilized to graze cattle in the forest reserve west of where some of the most outspoken proponents of paid hunting ranch. This heavily grazed range might well provide grazing for a substantial amount of Elk, but seeing as it has been grazed heavily they move beyond it to graze on private land for winter range. It would seem rational to most that if these landowners are so upset as to demand payment for feeding elk on his place, that maybe there should be an immediate moratorium of all public grazing allotments to ranchers in these hot button areas. We could run a 3 year pilot without grazing to determine if the Elk would use this public grazing land over private grass.
