How Trees Bring Water

Permaculture Instructor Andrew millison explains how trees are connected to water in the atmosphere as well as water flowing through the landscape. This video articulates the amazing role that trees play to ecosystem and climate health, and how their removal causes the drought-flood cycle.
There may be some questions about the scientific validity of the concept that forests attract rain. Here are a number of peer reviewed scientific articles to support the hypothesis which suggests that forest cover plays a much greater role in determining rainfall than previously recognized. They explain how forested regions generate large-scale flows in atmospheric water vapor.

Another important concept from the video is that condensation and evaporation in large areas of forest causes moist air to flow to land
From the abstract of the article below: “ Intense condensation associated with high evaporation from natural forest cover maintains regions of low atmospheric pressure on land. This causes moist air to flow from ocean to land, which compensates the river runoff….High evaporation and large extent of natural forests guarantee both a stable and high throughput hydrological cycle. Forests protect a continent against devastating floods, droughts, hurricanes, and tornadoes. Sustaining natural forests is a sound strategy for water security and climate stabilization.”

I have changed the title of this video from "How Trees Make Water" to "How Trees Bring Water". I still support the idea of trees "making" water available in the landscape. The second definition of "make" is: _ 'cause (something) to exist or come about_ '; bring about. But my use of the word "make" was distressing to many people, because trees don't actually construct water molecules from Hydrogen and Oxygen. And the point of this video is really to encourage the planting of trees as a tool for climate stabilization and landscape rehydration. Because Trees Bring Water :-)

Yet, plants do create new water molecules too. They use the H in water from the ground and the O from air C02 and combine them into water vapour. So we are not, in fact, drinking dinosaur pee ’distilled over and over’. The atoms are recombined (but to know that we must use the complete photosynthesis equation, not the simplified models)

[@BBnibhon]

One immense effect of condensing of vapor to the atmosphere explain by physical chemistry. While vapor is condensing, it create contraction 270/1 time of an empty space or vacuum and create none stop chain reaction of air flow in which carried vapor and condense continuously. Similar phenomenon take place in Polar zone where strong airflow is naturally move through out the year.

[@rebeccaw8820]

My thoughts exactly

[@thechief762]

Andrew, there is one seldom explained effect that you didn't mention. Besides trees, a well formed forest also contains a stratification of intermediate species, the layers of mid canopy, understory and ground covering plants. Stratification within a well formed forest system with all it's layers creates a temperature gradient with higher temperature within the high strata in the top of the trees down to the cooler temperature in the understory, and the coolest temperature in the lowest ground cover layer. Since cool air is denser, that temperature gradient creates air flow downward through the different strata with air flow eventually reaching the ground. As air cools, it tends to condense water on leaf surfaces in the lower strata, further contributing to water capture beyond what happens in the upper canopy you describe. Even underground, the fungal web can absorb humidity directly from atmosphere, if the soil is permeable and aerated. This means that not only are condensed water droplets absorbed, but also invisible water vapor can directly get into the soil. One reason why this is so important is that if you compare an unstratified monocultured forest to a fully stratified forest, the stratified forest will exhibit the above described phenomenon while the unstratified forest will exhibit the opposite. In unstratified pine or eucalypt plantations without understory plants, the net moisture flux will be negative because no downward airflow occurs.

What @thechief762 said is exactly right. The coastal temperate rainforest was broken by us clearcutting all the old tree canopy, all the flora and fauna below....if you look at the NW Cascadia forests you see that climate crisis is Big Oil and clearcutting all our cousins that helped create who? You and me. I think the conclusion of this video is the heart of the problem. We have the illusion we are separate from Mother Earth. In real time it takes centuries to grow forests we have cut down, plunder the wonder. But we can stop cutting down the Amazon, stop cutting the remaining old growth in BC and Alaska. And build a restoration economy that is premised on first do no harm, returning to an indigenous way of seeing the world. Trees are cousins. They breathe out, we breathe in. Trees are our family, not a source of pulp. Break through the misperception we are separate from Mother Earth. One simple way is to begin having conversation with trees, reanimate your relationship with all plants and animals. They aren't silent, we just stopped listening.

Through domestic birth rates and brining in cheap labor from Turkey and other countries, in those 60 years Germany's population has grown by tens of millions of people, totally negating the chance for the country to produce as much oxygen as it uses in metabolisms and combustion. The German forests are token nature, not real nature, as in all of central Europe. Germany could sustain a human population of 20 million, but 70 million heavy consumers of animal products is an ecological disaster.

Hello!! Well said 🙌

[@CanadianPermacultureLegacy]

The point you make at 4:20 is probably the most important of all of them. These raindrop nucleation centers are SO critically important. Another great example of this is when you have very very pure distilled water and cool it in a freezer to below freezing. It will still remain as a liquid until the water is shaken, then it instantly freezes. I'm sure most of us have experienced this. This happens because the very pure water doesn't have many nucleation sites to start (nucleate) an ice particle in the water. It's a bit of a different example, but just one that many people may have tangible experiences with. Similar things happen with very microscopically flat pots and boiling water well above boiling point before it boils. Then all of a sudden it flash-boils and can explode on someone. This happens often with microwaving water in a really smooth coffee cup. Trees creating nucleation centers for raindrop formation is so critically important. I didn't think you'd mention it, and I was going to come here and mention it, but I'm really glad you did, and makes me respect you even more as a fellow scientist/engineer.

[@codniggh1139]

On top of that, the shade from a tree reduces evaporation and creates a micro climate that can be noticeably cooler. 🌳 Thanks for the great video, you are great at sharing knowledge!

[@antondrosse6464]

and on top of that also water does not mix with water of differing temp's and water does not compress. so the water that goes underground will slowly come to the temp of the water already down there force the water already down there to move along. eventually finding its way to outlets we call springs. the tree's act as insulation getting the ground level to a temp close to 4 degree consistantly will enable a natural spring as opposed to a seeping spring.

[@jakewiddicombe8044]

Absolutely spot on !! Very well explained & nicely illustrated too. Planting trees is definitely the solution for preventing drought and fixing soil conditions as well as bringing & retaining water & moisture within the soil structure. I like that your conclusion is to go and plant trees, particularly starting near the coast and working with nature to bring water further inland helping to prevent drought and deserts areas forming. I understand this fully and have been planting trees recently in the UK, England, Cornwall. I have planted many native trees and will continue to plant many many more…🌱 Trees also soak up and store co2 & release oxygen in return which enables life to exist. I have been planting common alder this week which also helps to fix nitrogen back into the ground. There are so many benefits that come from trees and woodland areas. They provide shade, habitat, leaf matter, as well as the roots and all life that exists around it helping to nourish and aerate the soil. If you take a tree, plant at least two to replace it. Well don’t stop there, simply keep on planting more & more trees. Work with nature and become a part of it. Personally I find the whole process of planting trees extremely satisfying & rewarding… 🌱🌱

A million times THANK YOU for this video. I don't understand why this exact messaging isn't being put forth by large environmental organizations with this level of detailed explanation. It's not enough to say we need to plant trees, people need to understand the why. But maybe even more than that, people need to understand how we got here, and that the land around us wasn't always the way it looks today. Since the Bronze Age, our ever-growing population has needed trees for warmth, food, housing, tools, boats, furniture, and especially industry. Can't fire pottery and melt metals without burning trees. Weapons, cookware, food storage, canopic jars, glass, artwork, jewelry, just about everything an archeologist might dig up got there with the help of trees. Multiply that by 5 thousand years and by now 8 billion people who believe the human race cannot survive without enough toilet paper and Clorox wipes, and it's no wonder we're in crisis. THANK YOU.

Awesome job in communicating that well and with the drawing. it is almost exactly what I have observed over decades of doing reforestation work. in Ecuador in the late 90's UBC Canada researchers where putting up water particle nets, but they plugged up with the living air plants. it was a time of pushing the carbon credit imported pine tree mono platations in the wrong echo system, as I witnessed indigenous communities destroy small native patches of high elevation brush forest. so a few of us pushed for a native tree nursery we built up, yet sadly the centre for studies and international cooperation told me they cut there environmental part of community development. I found however near the cloud nets that "Chilca Negra" grew like a wild native "weed" but its leaves formation act as partial channels to the hexagon stem that is slightly indented to drop the water to the base root of the plant. its a incredible natural technology of nature. sadly tho the climate change gatherings tend to divert attention from deforestation. where I sense the big issue is "investors" want to make quick return of profits from there investment by simple log and simple lumber and chip exports. Rather then community selectively log the trees that are beginning to rot or over crowd, and then processing locally the wood in to finished local products where you can not then make money from investing money, but you have to do the work to make a living and so many others can as well.

Thanks for this! 💚🌲🌳🌦💙 I love hearing & seeing this system explained with Andrew's fabulous illustrations. I'd love to see him tackle the increased transpiration cycle from keystone burrowers in arid temperate grassland climates that can't sustainably support forests. Bill Mollison listened to the Navajo legends of prairie dogs crying for rain & understood how their burrowing draws up moisture from the underground aquifers that move with the tides. I think it's fascinating how the prairie dogs perform some of the same ecosystems services as trees, in different ways, & from different kingdoms. Nature is amazing. I love zone 5. BTW, prairie dogs are down to 1% of their historic populations. Both deforestation & killing off native burrowers contribute to increased drought & desertification. Restoring both is important work.

[@amillison]

Wow, fascinating. Where did you hear about the Bill Mollison part of that?

[@asktheanimals]

@@amillison , YT doesn't seem to let me reply to this thread. I have no idea why. I've tried twice. I suggested a search with Bill's name & prairie dogs. I mentioned his trip to the SW swale system when he learned of the Navajo story about PDs crying dor rain... let's see if this shows up. If you are seeing 3 replies, my apologies. They're not showing up on my end. 🤔

[@amillison]

I see this reply. Thanks and I'll see if I can find that.

Beautiful and effective illustrations, what a great educator

[@jordanmayne3366]

Everybody deserves this kind of ecological education. Trees are more than trees!

[@Dancerlil]

I knew a few things about trees such as how they help clean the water, however this was absolutely fascinating ! Thank you for the education Andrew. I have been a fan of permaculture for some time. Just recently found your highly educational channel. In grateful appreciation. Liliane

[@suneetsalvi1200]

Your are just too good Andrew ji. Love your sketching and way of explaining. Trees also break the impact of the rain drops and prevent soil erosion.

[@SonicPhonic]

Great video. Both my parents were from farming communities. We always had gardens and now all my family enjoy gardening. I tried promoting gardening while working with summer camps, but my boss always came up with some excuse. With climate change, drought, flooding, famine...we have to start considering that some politicians and rich business men don't care whether people die or not and go from there...

[@growabundant]

Love this because the trees are our most loving partners as we are people of the trees. I hope this is spread far and wide! ❤

[@BongLoy13]

In South Korea, we have 식목일 - tree, planting day, where people are encouraged to plant a tree : ) I'm sure it's made a big difference throughout the decades.

Learning about how drought works is the biggest thing i've discovered in a while. Even after watching all these science documentaries-

you are a role model this is so useful for my for my contry, keep up the good work greetings from Bolivia

[@Angie2343]

Crysta from FernGully was right. Trees DO make rain!

[@henriinwanguma8762]

This was 7+ minutes of distilled education. Thank you for making it easy to understand. Important to add that there are variations to all you've said depending on topography and prevailing winds for example.

[@naimedwards1422]

Great connecting of the dots from the individual tree to the Continental landscape! 👏🏾

Your a great artist ! I love it . I saw this in my town . Shopping center I was at got no rain 🌧 as I drove one block to my home 🏡 that had lots of trees and it was Down pouring of rain . I do believe the trees bring rain 🌧!

[@joshmcdonald7196]

And u also confirmed a lot of things I already knew. Thank you. Now I understand the whole system. At least as much as we know so far. It's so beautiful

[@hhwippedcream]

You are a phenomenal teacher and love all of your videos. Thanks much. This brings to mind the microbiota/fungi below soil that contain the water and extend/enhance the soil stability and water carrying characteristics. Exchanging photons for electrons via the circuitry of water. Trees are just enormous phase altering portals for elements in the air, in the earth and through the water.

This is a wonderful, *wonderful* inclusion of previously overlooked or undersupplied masses of information. I remember driving past a highway of lined trees, raining only where the trees were.

[@jhonhoyos612]

I live in my dear Colombia , and I have planted several mangos trees , I hope someday they give fruit , shadows and help to bring rain even though I won't be here anymore to enjoy all of them.

I need to send this to the local county planners and see if they'll sponsor new coastal planting

[@louisegogel7973]

Give them a video or two on Geoff Lawton explaining various ways to make water catching part of the landscape… then the trees have a super chance to establish and recharge the ground water table.

This was very enlightening and a great explanation!

[@nunamvseravno]

Absolutely CORRECT! There is an old saying: "For every man should have a tree to write his name to!" So plant a "buddy" buddy. We have to find ways to stop destroying our own nature!

Thanks for watching!

[@jaymedomejka1977]

I live on a natural short grass prairie where climate and moisture create conditions where trees really struggle without added irrigation. Do you think in the future you could put together a video of how important the prairie ecosystem is for sequestering carbon and holding soil moisture? I am all for planting trees, but context is important.

[@amillison]

I did mention climax prairie ecosystems in my last video: How to Fix a Broken Ecosystem

[@jaymedomejka1977]

@@amillison thanks. I'll find it.

[@tomasck2973]

Omg please that'd be great! I also live in a flat grassland part of the world and would love to see his explaination of how they work.

[@louisegogel7973]

Swales, water catchments… working with the land through permaculture principles to plant the water back into the land… there are many videos a s sites which speak about how to do this… watch and read them all. I like Geoff Lawton’s videos a ton, because he explains as he demonstrates.

[@emrusso4625]

I refer back to this video regularily & share it more often. Thank you! With massive pressure on the coastal rainforests in B.C., you have made clear why it is crucial to protect existing forest ecosystems. The only issue I have with your video...at the end..."go plant a tree." Yes. In 10, 20 years, if it survives, it might make a difference. Please, please, please stress the importance of protecting old growth forest ecosystems ❤ first and where they are gone, plant a forest of trees and shrubs and wild things.

[@khusi231]

Nice explanation why trees and all natural resources are so important

[@marysuewhalen5446]

Your knowledge is brought to life and so beautifully displayed in your artistry of the environment and how it works. It’s mesmerizing!
