Yes, I am in favor of doing our best to return America's savannahs back to their previous state, though that state was not quite "wild" as you rightly point out, as Native Americans tended to the land and practiced regular burning of both the forests, savannahs, and plains. Likewise, bison did a huge part and sadly they cannot do that huge part anymore. But we can still get the land back to something healthier for everyone. My cattle (Jerseys, I do not raise commercial beef cattle) prefer my savannah land. I have approx. 100 acres of oak savannah which I have worked hard to restore to its former glory. My savannah (I don't call it pasture, it's not) is far more productive and biodiverse. I do have to remove my herds from it because trees cannot handle the constraint weight and trampling of large animals, and so I do also have a small 20 acre pasture that I keep for the off-time. I also have a 5 acre lot I keep for the winter months (Jan-April) so my cattle don't destroy dormant plants and so the grasses have time to mature in the spring.
