I have about a one acre "pasture" that has mature elms plus some evergreens, bushes and seedlings I planted growing. I used to mow under there, but because of all the trees, it'd take literally 3 hours just for that area. So, the past 2 years I've just let it grow up. My plan was to put sheep back there and maybe some goats. The goat idea is pretty much out because I know they'd eat everything they could reach. But what about sheep? Would they leave the trees and seedlings alone? I thought about sectioning it off in 1/3 acre parcels and rotating them. How many sheep could I really put in this area to keep it fairly manitained?
