This is like the “food forest” concept described in permaculture, but on steroids.
The overarching idea is to create a forest-like ecosystem, but with as many of the niches filled with food-producing plants. For example, this could consist of a:
- canopy of fruit or nut trees
- a middle layer of food-producing bushes (rainforest plants should be a good fit)
- ground layer of supporting plants, adding nutrients or attracting beneficial bugs
Contrast this to a typical orchard: the trees are carefully spaced to maximise production, but underneath there’s nothing but grass that needs to be constantly mowed. The trees themselves need constant feeding and management.
The orchard produces the most fruit, but only the fruit. The edible forest garden has more competition between plants, so the canopy produces less. But when you add up all the food produced at all the layers, it wins hands-down. Better yet, by mimicking a normal forest, only a little management is needed, and hopefully no maintenance.
Has this been done in Australia?
The original ideas come out of North America and the UK, and this is where most of the real-life examples come from. I’ve heard of a few small-scale gardens in Australia, but I suspect there’s not many in total.
So my goal is to fully explore this concept in temperate Australia, utilising native bushfoods and rainforest plants wherever possible.
The books are very heavy-weight, and the approach requires a huge amount of planning. It may be 6-12 months before even the first plant goes into the ground.
I’ll write up our journey as it progresses, starting with our goals for the edible forest garden, and then working steadily down into design details.
Give us 10-20 years, and voila, there should be an edible forest! Lucky for us it’s the journey we’re looking forward to 🙂
PS. the pair of Edible Forest Gardens books are excellent, and I’d highly recommend you get a copy if you want to take food forests to the next step…
