If fruit tree canopy area is more than 25-30% of the total area; then the system is not in balance (if you include nut trees too, then it needs to be something 50-60% nuts and fruits - 40-50% fixers and mulch generators). Any fruit produced than that is excessive, which will create a network for pests to navigate through without encountering predators. Even these figures are upper limit, I prefer to aim for 10-20%, to keep work minimum.
