Design using Zoning helps us place elements where they are needed according to level of observation and attention. In Permaculture we break the design up into Zones according to the amount of attention each area requires Zone 0 – Home = indoor production (sprouts/ferments) and processing of food, waste, water collection, repairs and education. Zone 1 – Area outdoors needing regular observation tending and harvesting eg. plants we can browse and use each day.- intensive garden beds with keyhole access. Zone 2. Less intensive managed areas but with animals needing daily attention eg. poultry, rabbits, worm farm, snail farm. Orchard trees. Zone 3 Occassionally visited areas with self-fed animals (stock) and seasonal wide ranging crops eg. corn, wheat, rice, pumpkin, bamboo Zone 4. Wild food gathering (eg. nuts, native fruits) Wood for Fuel, self seeding trees Zone 5. Natural area – a rarely visited area. linked with neighbouring wildlife corridors. Sometimes managed to reduce risk of catastrophes ie. fire/pollution/drought/hurricane.
