The Surprising Downsides To Planting Trillions of Trees (vox.com) 115

Large tree-planting initiatives often fail -- and some have even fueled deforestation. From a report: On November 11, 2019, volunteers planted 11 million trees in Turkey as part of a government-backed initiative called Breath for the Future. In one northern city, the tree-planting campaign set the Guinness World Record for the most saplings planted in one hour in a single location: 303,150. "By planting millions of young trees, the nation is working to foster a new, lush green Turkey," Turkey's president, Recep Tayyip Erdogan, said when he kicked off the project in Ankara. Less than three months later, up to 90 percent of the saplings were dead, the Guardian reported. The trees were planted at the wrong time and there wasn't enough rainfall to support the saplings, the head of the country's agriculture and forestry trade union told the paper.

In the past two decades, mass tree-planting campaigns like this one have gained popularity as a salve for many of our modern woes, from climate change to the extinction crisis. Companies and billionaires love these kinds of initiatives. So do politicians. [...] There's just one problem: These campaigns often don't work, and sometimes they can even fuel deforestation. In one recent study in the journal Nature, for example, researchers examined long-term restoration efforts in northern India, a country that has invested huge amounts of money into planting over the last 50 years. The authors found "no evidence" that planting offered substantial climate benefits or supported the livelihoods of local communities.

The study is among the most comprehensive analyses of restoration projects to date, but it's just one example in a litany of failed campaigns that call into question the value of big tree-planting initiatives. Often, the allure of bold targets obscures the challenges involved in seeing them through, and the underlying forces that destroy ecosystems in the first place. Instead of focusing on planting huge numbers of trees, experts told Vox, we should focus on growing trees for the long haul, protecting and restoring ecosystems beyond just forests, and empowering the local communities that are best positioned to care for them. In the past three decades, the number of tree-planting organizations has skyrocketed, growing nearly threefold in the tropics alone. So have global drives: Today, there are no fewer than three campaigns focused on planting 1 trillion trees, including the World Economic Forum's (WEF) One Trillion Trees Initiative, which launched in 2020.

          The only way to plant more trees is to grow less food.

    • Did anybody really think that planting a few trees will offset the Gigatons (with a 'G') of CO2 the human race is producing right now?

      It's simple math: Per capita we produce about 4.5 tons of CO2 per year. To produce that much wood every single person would have to plant about a hundred trees (they grow slowly). In the USA you'd have to plant three times that.

      OTOH: Maybe tree planting has other benefits. Long term benefits like having a working ecosystem.

Bamboo doesn't allow for the lush green lawn acreage that reminds people of massive British estates and Southern USA plantations which are still looked at as a status symbol for homeowners.

      It's just more evidence of climate change and people (particularly politicians and NGO's) not paying attention to the science.

      If you plant trees, you plant them in the fall, because that's when the trees normally go to seed.

      If you plant trees, you plant them in the rainshadow of other trees, otherwise they will drown.

      If you plant trees, you plant only NATIVE trees, otherwise they will just die, drown or become diseased.

      Trees, in the context of humans are basically toddlers. They need support of other trees

      • Don't forget to have trees at different stages of their life together. A forest comprised solely of ancient trees is at risk of all dying at roughly the same time. Stagger what you plant and when so patches of light can support lower vegetation. Different species are susceptible to different diseases, so a biodiverse forest is more resilient. Also, since many hardwoods take 100+ years to reach maturity, you can ensure continuous harvests by planting saplings every year.

    eg by planting trees in an arid area, and others simply use it for political gain, it doesn't mean the idea itself is wrong. There arn't currently many other ways to suck up huge amounts of carbon other than planting trees. Yes, plankton in the sea but good luck seeding that on a large enough scale to make a difference.

      But it does mean it's more complicated than it sounds.

      What these programs are attempting to do are actually complex, multidisciplinary undertakings that take a lot of up-front research, preparation and long-term planning. Anyone with sufficient power -- political leaders and billionaires for example -- can order that so many trees get planted, and it will happen. But if that's *how* it happens, it's no surprise when 90% of the trees die, or when the trees aren't what locals need.

    • The problem I learned with seeding plankton in order to capture carbon in the seas is that it ends up being much like this. While some of the plankton may sink to the ocean bottom, roughly 90% of it will be consumed before it gets to the dark depths, and 90% of the remaining will generally be consumed before it reaches the ocean floor. What reaches the ocean floor will generally be consumed by the critters there.

      Basically, if we seed plankton and grow a bunch more of it, the net result is more ocean life,

          "The plankton capture the carbon."

          Not really, its still part of the active carbon cycle. Same as planting trees. The carbon isn't sequestered.

          The carbon from the fossil fuels was sequestered for millions of years, it wasn't in circulation at all. It was completely out of the system.

          The carbon in oil and coal etc in the ground represent millions of generations of forest growth. Trees growing, pulling carbon out of the air for thier biomass, sinking down, and being sequestered as oil, removed from the system.

          • So planting a trillion trees is not creating a carbon sequestration engine that will pull carbon out of the atmosphere and sequester it and gradually reverse the carbon release we've done. Instead its its basically just pulling the current living biomass of the forest out of the air for as long as the forest exists, and that's it. When a generation of trees die the carbon circulates into the atmosphere instead of being sequestered to eventually become coal/oil.

            In the Fall I often go through my woodlot and cull the recently dead trees for firewood. Its a lot of red oak that have reached end of life, they are huge, but dead. I jokingly tell people that I spent the weekend liberating sequestered carbon (ie, processing firewood), and they usually look at me in a befuddled way, having no idea of what I am talking about. I often wondered what the point of planting trees is (I mean, as you say, you are really only sequestering 1 generation of carbon). I suppose some

        • What, specifically, do you think happens to the carbon in that cycle? Once the plankton is eaten, what do you think happens to the carbon?

          Well, that would generally be called "respiration", where the carbohydrates, fats, and proteins are oxidized for energy(with a small amount being reutilized to make the flesh of the consumer), releasing CO2 and H2O. Basically putting you back where you started when the plankton was converting CO2 and H2O into carbohydrates, fats, and proteins via processes that started with photosynthesis.

          What about it? Fossilization is a rare event that involves bone being replaced by minerals. It has nothing to do with carbon capture.

          "rare event" is the point. A piece of carbon even many times removed from the plankton that photosynthesized it, being

    Renewable forests that are used for lumber ARE replanted in this manner, with people paid to do it. Of course, you need to do it at the right time of year, with the right type of soil, and you need to have the appropriate amount of moisture and fertilizer.

    It's a method that works just fine, and shouldn't be discouraged by crappy articles like this one. You just need to do it with the right techniques.

    Of the 150+ saplings I've plants on my lot, we've lost about 20. Some to a mower, some to deer, some to overspray from nearby fields, and some to just plain bad luck. And that's in an area that was paid attention to, fertilized, and watered.

      Well said. Put another way, farming isn't trivial. It sounds easy...some apparently think they plant some seeds in late winter/early Spring, pull out some weeds here and there, water as needed, then harvest some awesome food in fall. Farmers will laugh at your naivety. If you've even planted a garden, you know it's not that simple. My first time, I threw some basil seeds in a lot, got an OK yield, they died a bit early. 15 years later, lots of reading, youtube videos, conversations with older, smarter people, my harvest is 10x, but that's learning lessons about plant disease, watering, fertilizer, early seed starting, buying a grow light for Feb planting, etc. This year, I planned everything PERFECTLY, to my knowledge, we had a lot of tropical storms and it decimated my garden in august with fungus from an unusually rainy summer. My garden looked AMAZING in July. I lost 1/4 of what I grew in August just due to powdery mildew and some unspecified disease that annihilated some sedum groundcover I was growing. Half of what I grew died early.

      Growing shit is kind of hard. If it's easy, you got lucky, but it is a roll of the dice from year to year, and getting good yields every year requires a lot of wisdom, thought, planning, etc. So yeah, a bunch of people with big dreams, a large volunteer workforce and a ton of saplings are going to run into all the issues any farmer or even gardener will run into. If you pick the wrong plants or the wrong spot or don't know how to manage pests and disease, your plants are in for a world of hurt.

      This article is just disrespectful to farmers, greenhouse operators, and anyone in the agricultural/horticultural trades. Just because it looks easy to the author of this article, doesn't mean it is. These planting tree programs are great. They only contribute to deforestation if you do it stupidly.

      Most of their examples fail because they pick the wrong plants. Anyone knows this. Pineapples don't grow in Michigan. Most plants that thrive in Siberia won't do so well in the tropics. They'll love the sun, but have no clue what to do with the diseases and pests of the area. Many plants HATE water and get root rot easily. Some hate intense sunlight.

      You need a lot more than good will and love to grow things. You need to know what you're doing.

      IE you pay attention to all the little details like whether the species you're planting can survive there, whether the weather is right for planting, the soil is rich enough, the saplings are healthy enough, etc...

      You don't try for "records" like "most plantings in a day" because that just encourages you to ignore all of the above to toss seedlings into the ground for the press confe

      Obviously I haven't read TFA, and this is pure guesswork. What else does one expect from /.? But it seems to me that an important question to ask is why the area lost the forest it previously had. In the UK it was largely due to tree felling either for shipbuilding timbers or to clear land for agriculture. In other places I wonder whether it's due to changing patterns of water usage which mean that the area can no longer support a forest.

    The authors found "no evidence" that planting offered substantial climate benefits or supported the livelihoods of local communities.

    I'm not sure what tree planting has to do with helping out local economies.

    However, planting more trees to mitigate climate change is a global push, requiring increased planting everywhere. I'm not sure how studying one region in India can definitively say if tree planting programs have any effect on climate change.

    • nope, old mature forests are carbon positive, they make carbon pollution! Sorry to burst your bubble but it's best to leave nature the fuck alone and just reduce our own pollution.

    Here's a direct link to the research article. [nature.com]

    I'm not a statistician, so I have a hard time making sense of how they went about this study. It sounds incredibly convoluted and a lot of assumptions were made from satellite data and what, exactly, a pixel represents (broadleaf, pine, grassland, etc). The satellite imagery they used was only 30m, so a single pixel represents quite a large bit of land.

    It sounds like this is more of a societal thing - the way they go about planting trees. This portion deep in the article pretty much sums it up:

    most tree planting happens within areas that already have some tree cover, limiting the potential regrowth opportunities. Planting in cleared areas is not a viable alternative because of socioeconomic and ecological constraints of converting agricultural lands back to forests.

    So trees are being planted... amongst other trees. Anyone who spends time in the woods knows that a mature wooded area develops a canopy to the point that it shades out the growth of other plants and trees. That is why in most mature woodlands you can easily walk through the woods, because new things can't grow well beneath the canopy of mature trees. This is also why mature trees in a forest setting only have limbs near the top.

    So in other words, planting more trees right around existing mature trees doesn't have much affect. I don't believe that is the kind of tree planting done in most other parts of the world. I know around here, fields and open areas are being reclaimed (naturally) by trees, as small scale farming has become less and less profitable. Where I grew up in Ohio, we lived next to a large, mature forest of trees covering hundreds of acres, and as kids we played in those woods quite a lot (that was 40 years ago). Deep in the woods were large piles of stones (4-5' tall) that extended in straight lines for several hundred of yards, parallel to one another. Those used to be the borders between fields, and those were the stones that farmers had tilled up and stacked out of the fields a hundred years before. It is totally forested still, and the oldest of those trees are now approaching a hundred years of age. This was land that was not just totally deforested to open fields, but also had the rocks and stones manually removed.

    Just planting a tree is useless (in fact, it's a waste of money, manpower, a living being [the tree], gasoil, etc.)

    If you want *to make a change* you have to:
    1) Plant the tree
    2) Secure it water/nutrients for, at least, 10 years
    3) Trim, clean, cut down, etc. to keep the ground "healthy" (the ground needs also the sun, it has to keep nutrients so there must not be big trees too close to one another, etc.)

    Ain't you going to do ALL that? Then you're just making things worst.

  • The example in the posting for this article is not a downside, it's just stupidity. The tree planting would have been more successful if they had planted at the right time and looked after the saplings.

    Forests need an ecosystem of many, many animals to work.

      Forests need an ecosystem of many, many animals to work.

      Not just animals, but various species of plants. The typical life cycle of a forest involves clearing due to fire, disease or floods, followed by pioneer species [wikipedia.org]. Many of which provide beneficial functions like nitrogen fixation and shade. And then you get the stable, slow growth but long lived species following on.

      Trying to jump directly to species suitable for old growth forests messes up the ecology. Not only for trees, but animal species. Old growth is a shitty habitat for many prey and predator animal

  • Claim: "large-scale tree planting initiatives sometimes lead to deforestation"

    Fact: this was not a tree-planting initiative. It was an economic incentive to turn jungle into economic crops. From the link in TFA https://www.bloomberg.com/news...

  • It is axiomatic that stupid people do stupid things. Nearly all politicians are stupid people, when it comes to anything other than their own well-being. The corollary is left as an exercise to the reader.

  • It is expected that not all saplings will grow, hence they are planted very densely. Even of those that grow, some will get crowded out within a few years.

    However planting bare root saplings at the wrong time of the year is a gross mistake. I bet they weren't even area-native species either.

    Planting appropriate plants for the area, at the correct time of year, in areas with no existing tree cover (possibly due to historic deforestation), but the right conditions for trees to grow, is fine.

      A plant has a huge element of chance. It's a roll of the dice. What worked perfectly for you would kill your neighbor's plant the next year, month, etc. Some kid in your town who replicated the experiment could have planted it in an area with contamination or fungus. Another kid could have a deer eat it and kill the plant. Another kid could have a pest infestation.

      Growing things are far from deterministic. I've had plant species I thought were total weeds and idiot-proof because I got a 90% yield

  • The summary mentions deforestation twice but doesn't provide any elucidation. TFA does however:

    In Mexico, a $3.4 billion tree-planting campaign launched by the government in 2018 actually caused deforestation, as Bloomberg News’ Max de Haldevang reported earlier this year. The program known as Sembrando Vida, or Sowing Life, pays farmers to plant trees on their land, but in some cases, they would clear a chunk of forest before putting seedlings in the ground. One analysis by the World Resources Institute, an environmental group, suggests that it caused almost 73,000 hectares of forest loss in 2019.

    For a very long time grazing animals helped spread the grasslands. A herd of animals moves into an area, nibbles at the grasses, stirs up the ground with their hooves, spreads seeds in their hair and feces, and so on. Managed grazing can turn desert into grassland. To make this profitable people need to eat meat. The grasslands build up topsoil and capture carbon in the soil. More grass means

  • Trees are no different than any other species. You have to establish their habitat before you can expect to plant a lot of them and see them thrive.

    What's missing here is landscaping to retain the right amount of water, and regulate its flow. Rainwater has got to be captured, retained, and allowed to move slowly through the landscape, and this usually means swales, berms, and lightly angled ditches. The next important part is the soil biome. We need to be farming for soil microbes to unlock its nutrient

  • I can't speak to the Turkish project, although one does have to wonder about the competence of planting millions of saplings, and then not ensuring they have enough water to survive. The thing is: re-wilding takes more planning than "plant a million trees". A forest has a lot more life in it than a bunch of trees, even if you do water them. Best is if you can work off of existing wild areas, and help them to expand.

    Anyway, the real solution is to re-wild farmland. Certainly in the West, we have far more f

  • The headline suggests that it's bad somehow to plant trees. So, the Turks did it incorrectly and a lot of the trees died. Other places have had planting campaigns that didn't work out to anyone's benefit, so say some researchers. The writer even asserts that planting campaigns contribute somehow to deforestation but offers no support for this statement. I agree that there is a virtue-signaling aspect to the activity, but I fail to see what harm there could be in planting trees. At best, they make oxygen

  • My dad had a PhD in 5 related fields, including ecology. He was often called in as a professional witness regarding the ecological impact of mining and logging operations. One thing I learned from him is that it's unhealthy for all trees in the forest to be the same age. We need to stagger the trees we harvest and how many saplings we plant at a time. Old trees are more susceptible to insects, fires, and diseases. We don't want the whole forest to die at the same time.
