Let me know when you have a goat that will eat thousands of pounds of fallen trees.
No offense, but it's fairly clear you have never stepped in the forests that this is a problem. It's not yearly grass. It's 50 years of buildup. You make a 12ft high and 30ft wide pile of this stuff then please tell me about goats.
From experience, had a bone fire that lasted three days before it was out.... Goats...
Along the same lines, you have an excellent wolf feeding solution, now to find the problem it solves!
