A simple solution of course is to fence it all in, but that doesn't seem very permacultural.
Why don't you grow a
live fence? That is
very permaculture. For instance, check out pages 8&9 in Gaia's Garden, 2nd ed., where Toby Hememway goes into deer-deflecting hedges and the like. Such barriers are discussed in much of the permaculture literature. There are lots of thorny, fast-growing species that fulfil several functions at once -- they not only deflect the critters but provide edible foliage, fruits, and roots; wood for building and fuel; they can serve as windbreaks, etc. Just work them into your design. At the very least, they can cut down on the sheer amount of man-made fencing you'd have to purchase and erect.
As for slugs, as someone once said, you don't have a slug surplus you have a duck deficiency. Of course, that's only one way to handle slugs but it might be worth considering as another solution that also provides multiple benefits... as well as creates some new problems, but on balance, [s]like women[/s], they might be worth it.
