Hi [member=200704]Leefle[/member] , I wonder if, rather than us trying to teach our Grannies to suck eggs, you tell us how much you know, and which aspects of forest gardening you have found would work for you? Then, ask specific questions. Open ended topics tend to end up not being relevant unless you let us know precisely what you want to know, and give feedback when someone has offered an answer. You have found that it is possible to keep sheep in a forest garden, but if we know what you are already considering then we can give our relevant experiences.
I grow a lot of trees, but for them to survive I keep my sheep well away from them, allowing them only to eat overhanging leaves and branches, or branches we have cut for them to eat in winter.
Similarly, our sheep are not let anywhere near our veggies, or we would have none.
