How to edit existing activity zones in dwarf fortress?

I have a pasture that I want to assign more animals to. I assume there must be a way to do this without deleting the pasture and creating a new one, but I really can't figure out how to do it.


Solution 1:

Open the Zones menu with i, move the cursor over the pasture you want to edit, then press N. This screen will let you manage animals and assign them to that pasture.
