> Specifically: raising 200 goats, trucking them around from place to place, the human logistics (and their vehicles and food and supplies) and the cradle-to-grave carbon expenses of every piece of this activity ... it's not obvious that that is smaller than the released carbon of 10 acres of spindly brush.

I think the advantage is that goats are easier to control than fire, especially in very dry conditions, which is why they are used in high fire risk urban areas.
