- Miyawaki is a dense, fast-growing forestation technique that enhances biodiversity and mitigates climate change. Its benefits for the UK include restoring ecosystems, improving air quality, and providing green spaces for communities, fostering well-being and resilience.
This project is part of the Trees Outside Woodland project led by The Tree Council.
I planted a native forest in my urban yard and alley 7 years ago. 5,000 sq. ft. with over 400 plants and 75 native species. I covered the cut lawn with 4-5" of medium/large bark and removed all non natives. NO soil prep. Dig holes, add a little topsoil and plant natives. I have 24 Alaska cedars, 8 Shore pines, 2 Douglas firs, 2 Red cedars, 8 vine maples, 7 Douglas maples, red flowering currant, serviceberry, evergreen huckleberry, native blackberry, tall, short and creeping Oregon grape and many more shrubs and lower level plants. Tons of habitat and food for songbirds. The forest is thick and tall. Air is cooler (12-15 degrees F.) and moister in summer. Local cats will come to kill native songbirds. I drive cats off with Broox ultrasonic ground level defenders (I am using 4 of them). And Havahart trap and release after a few hours. No hurt cats. I water during hot summer periods as the forest is still young. Shade is finally showing up on this little forest in Mount Vernon, WA USA. You can do this in your yard. Avoid big tree planting over water lines. Thanks.
I bet it looks absolutely gorgeous too.
Please share pictures and videos. 🙏🙏
Please share a video, sounds really impressive!
I remember reading about the Miyawaki method as a sidebar about potential reforestation techniques in the 2016 Project Drawdown book, it was such a small passage but really seemed like it had a lot of potential. Amazing to see this continue to be tested and the potential it shows!
I would like to see more videos on what we all can do in our gardens, no matter how small the garden. Its a great video, well done everyone
We got a team dedicated for Miyawaki forestation here in India. Key to a successful afforestation is to grow only trees endemic to the respective land. Miyawaki method really really is extremely satisfying with amazing results.
Hi 👋🏼
Do you mean the team of Afforestt?
India is doing so many things for nature as well as protective measures for what it has got. Such a good example to the rest of us.

Wow, this is such an interesting comparison between the two methods. Thank you for doing this trial, has definitely opened my eyes.
It would be quite interesting to see how some form of checkerboard planting of a Miyawaki Forest would do in a larger area. How would the planted areas spread to the unplanted ones? It is, also, good to see that those doing the planting here have used some of the rarer, less-common and more-historic trees, as well.
We have mismanaged the Once Beautiful and Bountyful Planet and its Time for All Nations to Restore all Vital Natural Ecosystems. Its so pleasing to see people to be genuinely concerened about restoring Mother Nature.😊
This is a phenomenal side-by-side trial and gives yet more evidence of the power of the Miyawaki method.
Great work - well done to all those putting in the patient hours doing the reasearch.
Excellent experiment. Thank you for sharing. Subscribed.
Shared on Landscape Architecture TV. Thanks.
They did mention insects, but no mention of birds. The dense planting is an obvious ATTRACTANT for many bird species.
It's sickening that damage caused by vandals has to be taken into account. Are there any plans on expanding the new growth to the control side? Do you intend on trying to join up Miyawaki plots with nearby existing woodlands?
Not really when you look at it in context. Saplings have always been destroyed by something. Think of those people as analogs for the bison that used to roam the land a million years ago. If you're trying to replicate the natural processes, accounting for damage and death should very much be a part of the experiment.
A very interesting video showing the benefits of this method and it is nice to listen to such well-informed interviewees explaining their underlying goals.
I abandoned a 17,000 tree project due to vandalism, it was so soul destroying seeing established trees vandalised and cut down, I sold out to developers
Oh no, how tragic. I've done restorations so I know how much work it is. So sorry this happened to you and to the planet. What a waste.
Sorry to hear.
Don’t give up. Everything adds experience and skills. Do it again, this time you can predict and avoid more potential downfalls. When you have that game perfect - you will compensate for all previous losses, especially emotional. Everything is a blessing.
I started this year in my local area and every tree has had branches ripped, plucked out of site for no reason, hitting with a ball... I always put another tree and some have been resilient but with all honesty is very tiring and if I don't see anything growing the next spring season I'm abandoning the area, I really get where you come from.
Wish whatever links people together did a better job, I believe I'd have helped you; I'm glad to know you got paid though, but in retrospect I think the trees and the land are something I'd have made you more money from than anyone on this Earth would've offered you.
Some trees were planted by us in Wallsend and less than 10% are still surviving and don’t look to healthy after a year . I might have shared this with the local council , but unfortunately govement body’s don’t like the participation of there residents from what I can tell
Just saw a landscape plan for a park in Cambridge Massachusetts that had 3 Miyawaki forests along about a half-mile of pathway.
This where effort and energy should be put in, not blocking roads and streets✌🏾
Interesting!
Excellent demonstration but I don't think this method is applicable for a large area of land as it would not affordable with the soil preparation in large scale. Very good for urban small scaled forestry garden anyway. Thanks for sharing! 🌿
Miyawaki specifically designed his method for small scale urban "groves" or mini-forests, it was never intended for large scale reforesting.
It works perfectly for what it was designed for. In most urban settings you never have more than 1/4 acre to maybe a couple acres of area to work with if you are lucky.
One meter deep digging is quite a lot of work and expensive. Wouldn't it be enough to plough the area and grow some nitrogen fixing plants like mustard and plough it under?
Actually Mirawaki did experiments and founf that the loosening of the soil down to 1 meter is important to the rapid growth of the trees root systems.
The control was planted without the deep dig, and they only had 75% survival of tree seedlings compared to 99% in the meter deep and densely planted area.
Yes, digging up the soil to that kind of depth is expensive, but they are trying to fast-track the natural process and nature wouldn't have had compacted soil. Trees would have a very hard time burrowing through the hard-packed ground, slowing down the growth of the tree because they're having to expend a ton of energy below ground.
While the trees will break up the dead soil in time, it's the time that's their main concern.
They could have easily just piled on leaves and chipped up trees from the local arborists. A foot or more of mulch left over a year's time would have broken up the soil amazingly well. However, the time that takes is time they didn't want to spend. On GrowItBuildIt's youtube channel, he has documented just how big a change a foot of leaves can make to clay soil just by letting the natural process happen. However, it takes months and months for those leaves to be broken down by the worms and incorporated into the ground strata.
There's no doubt that the leaves work wonders, but those wonders take a year to really materialize.
So what they've done by excavating the ground a yard deep and adding amendments is simply to replicate what would have always been there if no development would have happened over the last century. It's more expensive and all that, but it's also faster and allows them to see how the plants react when the soil is soft and airy, allowing the trees to root through the ground with minimal effort.
Were it me, I'd have opted to plant native wild flowers and grasses, turning the patch into more of a natural field like nature puts everywhere. That would allow the herbaceous plants to root down, break up the soil, create a lively biome, and eventually create habitat for trees. Of course, while easier and cheaper..... it would have taken a lot more time.
Saplings of many of those trees costs tens or hundreds of dollars. If normal planting leads to vandalism everytime, it's more cost effective to use the Miyawaki method and avoid wasting years and thousands of dollars in planting saplings doomed to be destroyed anyway.
Would be interested in seeing a proper scientific trial with a third control plot combining the Miyawaki prep with traditional planting density and probably even a 4th plot combining Miyawaki density with traditional (i.e. no/very little) prep.
Miyawaki himself already did a lot of texperimentation, as far as I gather from other commenters.
Brilliant! - but I wish more attention had been paid to the detail of the recipe, with a condensed summary of the key elements rather than dribbling this info out interspersed by other material. One thing not elaborated was the size of the trees when planted - bare-root whips I assume, for economy: the commentary seemed to say they were 'larger' - but without any comparator. Also how many tree species in total? It's not enough just to say 'more than usual'. I'd also like to know more about the subsoil - if digging a metre down in Bristol, 90% of the depth will be in alluvial ooze, and once mixed for aeration, the topsoil will be lost among the yellow clay subsoil. Is this REALLY desirable? And when mycorrhiza was talked of, woodchip was shown. Detail please!
Throw some edibles in there and you'll have a perfect situation. Growing mini forests in the urban areas is a great idea I think. There's got to be some native edibles that can go in these. On my land I have wild muscadine, paw paws which love to grow by hickory, mayhaws, and native pecan in addition to other varieties of trees and native flowers. I let sunchokes grow because they've been here for decades before I bought the land.
Mini forests can grow wild berries, lot of different herbs for both culinary and for medical purposes. Throw a couple squash plants and other annual vegetables around the edges to feed wildlife and people. I think every public place should become a mini forest or orchard, or community garden. Lawns are a waste of space but their clippings make the best natural nitrogen fertilizer.
I sent this documentary to my English friends and told them I am SO shocked ... 😲
"The ground was cleared after the Second World War for setting up the housing estate " ... that is 80 years ago, by MY counting ... !
What other re-forestation was done in the meantime ... ?
Obviously this project lacks common sense: where is hedgerow, juneberry and mountain ash which provide precious seeds for birds ?
I wish I had known this before I wasted my entire forest budget on a failed aforestation project
I don’t get why would someone vandalise the trees. It’s not that I just disapprove it, but I sincerely don’t get their reasons behind it.
Boredom is a powerful motivator to destructive human behaviour, both internal and external
Anyone heard of “Syntropic agroforestry”?
Anyone heard of warm socks?
No, but I have cold hands!@@oldbatwit5102
This mob have the right idea, try everything and see what works empirically
Nature 1 Monsanto 0 :-)))))))
plant wild rose with each tree and no more moron problems
3:47 challenges to growth ? there would NEVER be challenge in growing plants
What kind of scumbag kills people's trees like that?
1:00 Young woman has such a beautiful accent. Is she descended from nobility? Reminds me of Keira Knightly's speaking.
So, this is nice, just be aware it is a pseudo-scientific methodology. There is one experiment, as the video refers to it, comparing two different methods, Miyawaki vs standard contol, but I gathered at least 5 different variables between the methods. The discussion focuses on diversity and density of planting, 2 variables combined as one method. Other variables are mentioned in passing but not emphasized in reasoning, though they might actually be more important: soil prep (dug soil to 1 meter depth and turned over), organic mulch layer, and addition of fungi). Searching the net, there are many variations on what is called Miyawaki Method, it is not well defined. A thorough study would involve combinations of the variables to compare them all, requiring I think 5*4*3*2*1=5! (5 factorial) = 120 separate plots (to compare the many possible combinations of the variables) for each experimental site, and then be replicated at multiple sites. So what can really be learned from this? If you plant trees more densely then 3 years later you end up with a denser thicket. Well, that's not very remarkable. Similarly, if you start with a greater diversity of trees, you end up with a greater diversity 3 years later. Again, what else would one expect? Perhaps turning the soil over was more important than the other factors. Perhaps that raised up old organic matter on the experimental plot (which had been buried by construction material), and/or loosened the soil so roots could grow better. Perhaps the fungal seeding of the experimental side was more important. Certainly adding a layer of organic mulch was important. Given all the prep work on the experimental side, I question if it was truly cheaper than the contol side. How was that derived? Certainly, the combination of these 5 factors in one method does demonstrate more growth than the control side. Still, not everyone using a Miyakai Method uses all 5 factors. Given that so many factors were given short shrift in the presentation, perhaps there were other factors altogether which were not even mentioned? Things to study.
Get rid of the music.
How lost some humans must ne to vandalise small trees just for fun. 😢
So basically you mean Syntropic Agroforestry ?!
Syntropic forestry is different: it includes intense management: pruning, chop and drop, etc. It is very labor intensive. It also aims at creating an edible forest, even though it uses fast-growing tress at the beginning which will be chopped to favor the fruit trees.
agreed, agroforestry is farming with trees. At the start, there is planting, and later when the system gets going it produces its own fertlizer via prunings and interventions at various stages to maintain forest floor. But when cover crops take over from annuals there can be less, and it can become a forest, still edible one. @
It isn't as labor intensive as you think. The system produces its own fertiliser. But yes some intervention via pruning is necessary of the support species to boost the system. This accelerated effect via diversity and syntropic relationships could be revolutionary for farming. @
you payed for at 13 minute movie, so you get a 13 minute movie!
Pretty sure that should you throw as much money and effort to plant with the traditionnal method, you'd get good results anyway.
How would the traditional method plot do better with 30% LESS money being spent on it?
@@glennmartin6492 The cost of the "miyawaki" method is 3000$ per 1000 sq ft, that's 30,000$ per quarter acre. That's 120,000$ per acre. Traditionnal method of tree planting is 100 to 400$ per acre. That means for the same cost a 1000 sq ft patch you could already reforest 10 to 30 acres of land. At the 100k$/acre price range you might as well plant full sized trees with a built in irrigation system, natural ponds and all manners of top notch biodiversity installations. Beats the very purpose of this "alternative" method. Business speaking this is just a way to sell lots and lots of mini digger hours, manual labor, maintenance plan and play on 'green' sentiment, while doing huge margins doing extremely little meaningful work in reality.
What kind of jerk destroys a tree.
This system frankly is bollocks.
I especially love the fear-mongering. Good that they are putting in native trees, but you have to wonder what this fascination with woodlands is about. After all, nature in England made lots and lots of open fields, glades, savannah, and such. For every tree planted, you shade out a native wildflower that needs the open sunlight. In short, replacing the turf lawn with native wild flowers and forbs would be an excellent plan to "increase diversity". Of course, all the plans in the world won't matter if folks aren't working to stop the flow of people into the country. After all, you can't complain about losing land and natural resources to development and then not work to stop the very thing that drives that development. The UK is an island. That means there's only so much room and so many resources. The idea that they could just take in millions of people from around the world every year is ludicrous. Of course, you can bet that folks will fight that idea even though it's obvious on its face.
