Nice summary. No book needed.
My situation is on smaller scale in my front/backyard.. believe like 350ft2. Doing permaculture style. Thing is with all the mulching the snails/slugs have a beautiful place to live and they eat away almost anything I plant or sow. They eat the flowers from the zucchini, baby beans, etc, except my oregano 😃 
Tried years fighting them  with beer/koffie/eggshells/garlic/coins/catchingthem/killingthem:(. Even ate some snails(pretty good). Now just buying organic veg and letting be, have a plum tree and some herbs.  This year thinking about nematodes after they ate all the flowers of some new plants just planted for the spring, but not sure how good this is for other insects, worms. and if i F things up in a other way..
Any ideas?
