What are "zones" in a permaculture system?
They are patterns of human use. The zones start with yourself, your personal patterns, and what you do as a daily practice. From there, they expand out into your home, garden, neighborhood, watershed, and extended community, until, by the time you get to zone 6-ish, where you have no control over anything that happens, the zone has become a sector. Sectors are patterns of uncontrolled influences, and we’ll talk about those next week!
Here’s a primer on zones in a permaculture system:
Zones don’t have hard lines between them. There is edge, crossover, and change. As an observation tool, you can use zones to look for flaws in your design, and also to evaluate what’s working well. As a design strategy, zones are a super powerful way to make choices about where to place new components in your system.
And here’s another layer of information, in a video excerpted from the certificate program. Here, faculty member Crystal Stevens gives an overview of zone mapping in the home system.
Zone mapping calls into play these principles, among others:

Base Mapping: the germination of your design project
If your goals and ethics are the seeds of your permaculture design project, then your base map is the sprout!
As a landscape designer, you should be able to draw a map that is reasonably to scale. Later in this course, you’ll analyze sectors, vision social patterns, learn to identify keypoints, and so on, and apply this information to the multiple layers of your design.
But for today, just focus on your base map: a 2-dimensional, to-scale aerial view of your site’s boundaries and all of the immoveable components therein.
The base map might seem like a simple thing, but it can still be quite challenging to create. Indeed cartography on any scale can come with a steep learning curve, so be patient with yourself! If your first attempt at a base map is all funky and out of proportion, don't worry about it! Just make another one.
While you're climbing up the learning curve, here are a few tips that will make a huge difference:
1. Use a pencil. And an eraser.
And a compass. The directions matter. Use them, mark them, and learn how they relate to your design’s patterns and microclimates.
2. Use a measuring wheel.
Not a measuring tape. Invest in a rolling tape with a long handle that you roll on the ground. This will give you a much more accurate reading than if you try to stretch a builder's tape across the land. Or, if you have a fancy phone, you can download a free app like this one, and use your device camera to take near-exact measurements!
3. Learn your pace length.
Follow the instructions in this video to learn your pace length. This will be a huge help when you estimate distances on a landscape.
4. Use Google maps.
Get a satellite picture of your site and use that to help you create your base map. This video explains exactly how.
5. Make a grid.
Once you have your basemap sketched out, overlay a grid that breaks it into smaller sections. Go out and measure one of those sections and use that data to double-check your scale. Adjust as needed. These smaller areas will come in handy later on when you are selecting plants or designing details into the living spaces in your design.
6. Be precise.

PWG Faculty member Crystal Stevens writes on an assortment of topics around the home system. Here are some favorite recent articles:
Oregon State University offers a free online intro to permaculture course every Spring, which teaches beginner-level zone and sector mapping. In addition, many of their full-course videos can be found on YouTube, and they are well worth watching. In fact, we highly recommend you watch them all, since they have done such a good job and been so generous as to make it available to the public. We'll link a few below, about zones and sectors. We also appreciate Andrews "decision making matrix," which he describes in the third video. Fun!
