We presently have around 140,000.000 head of cattle in North America. Mob grazing can bring that up to most of 300,000,000 head. Folding Bison into the nix along with goats will allow winter grazing and strong weed plant utilization with the goats. When we are really keen we can follow along with mobile chicken wagons to process the manure in particular. All this will produce an optimized grassland, even superior to the natural grassland dominated by the Bison.
