Converting woods to silvopasture

Hello! Just bought 20ac in North WI!

I want to do sheep. Almost all 20 acres (outside of ~1 right around the house) are densely wooded. Not ideal for sheep, so I’d like to turn it into something more in line with their ideal without clear cutting. Sheep will not be introduced until late fall this year at the absolute earliest.

Do we: 1) clear the trees we’d like to and get fencing up to pasture a rooting pig (3) rotationally out there to kick up all the soil and “reset” the land this spring and summer 2) clear trees, sow seed over the woodland ground and leave it in hopes that new seed will displace the ferns/low woodland plants due to the changed lighting and stuff

If the hive mind has other ideas PLEASE share! We are in the idea stage right now. I’d like the sheep to mostly be on pasture. I only want 3 to start and would like to have 3-5 acres for them.

Side quest- what fencing would be best to go around 20 acres? Hoping to fence the lot and do smaller fencing for livestock within. Best fencing for sheep for 3-5 acres?
