The essential principle that a food forest is based on is the ecological concept of forest succession. If you leave a patch of dirt unattended for 50 to 150 years, you'll end up with a temperate forest. And all the layers will slowly progress from the weed layers all the way up. And if you keep on ripping it back to a veggie patch, you end up ripping it back to a weed layer. So as the wet, as the levels, the layers, the ground covers, the herbaceous layers, the shrubs, the tree, the climbers and everything else, establish themselves naturally in a temperate forest over 15, 150 years, what we do, we plant it up all at once or as fast as the water will allow. Putting the hardest species in first. And pretty well, this is a temperate forest ecological model. The only difference is we pick the species and the varieties that benefit us, things that we can eat, things that we can use, things that we like to look of. And ultimately, what we do is leveraging the processes of nature that evolved over hundreds of millions of years, rather than trying to reinvent how to grow plants and how to grow food. And what we do is we set up the way nature sets it up and then nature takes over because the natural processes have evolved over such a long time and they're pretty well perfected by nature. It's the most sustainable model you can actually get. In permaculture, we call it a small scale intensive system because we pack a lot into a small space and it makes it far easier to manage. Purely in terms of the energy and effort that you can actually put into the garden, you can produce four times as much than a regular farm, just because it's easier to manage spacewise. And the other benefit of this model is it's because you're leveraging a natural process, it means there's less inputs from you, there's less labor and effort. So it's essentially very low on energy, very low on inputs, very low on other resources. But if you want to take it to this level, what it's intensive in is information. You have to know your plants. You can keep it as simple as you like and use some of the processes or you can take it full ball. This is essentially Melbourne's first demonstration food forest. This is a pioneering work. It's the first time that a food forest has been squeezed into a public space and fully documented and it's all transparent and all published on my website, Deep Green permaculture. The pioneering work here is actually the means of squeezing a food forest which has been done in rural environments, down into a backyard. I've taken the American or the US technique of backyard orchard culture and blended it with food forest gardening to create a backyard food forest. And this is a proof of concept model that is shown to work. It's been running for six years so far. It's been trying to run as an experimental garden for ten years and will be documenting all the yields through most of it. I've only taken a two-year break from years 40, year six. Next year we'll be resuming the count and it's really just a proof of concept. And it shows that you can garden exactly like nature and create a very, very sustainable garden system that looks after itself.
