    I was curious and looked it up. Apparently it mostly happens between trees of the same species, with several causes.

    Most are mechanical. The tips brush against each other, and damage new branches and leaves. Both trees divert growth away from the area.

    Some also sense shading via red light. They focus growth away from shade. This means neither tree grows into the gap, since they are partially shading each other.

    It also helps limit the spread of leaf eating parasites. Again, particularly useful in a forest of the same species.

    So yes, the trees are social distancing, to avoid the spread of disease.

      Lol I thought you said you looked up at the trees, and just observed all those facts

        Considering how little conflict we currently have, compared to our population size, we are doing extremely well. Unfortunately, the conflicts remaining are spectacular enough to counter that.

      I think there’s also a corelation on how dense a forest can get because it affects the sunlight in ground too. If it gets too dark then life would rot underneath

        Well, if they were stinky I’d probably be upset. If their hands were sticky, I’d be upset. Repeat for the other social offenses. Otherwise, sure, go for it. We all need a case of mistaken identity in our lives.

    This is real? I read about it in a scifi (or rather solar punk) novel and thought it’s a metaphor or something

    This shouldnt happen in nature should it? Just talking out of my ass here but i feel like this only happens because they are all the same height because they were planted by humans at the same time. Or maybe only in mono culture forests, because i have never seen this simply because there is always overlap from smaller or different trees where i have been.

      Not only should it happen in nature, but nature causes this behavior. They evolved that way because they survive better than a species that gets tangled up in itself. That’s it. That’s the whole reason, start to finish. There are a multitude of reasons why not getting tangled up in your neighbors is good, but the tree simply has to survive better, and that is all that is required for the behavior to become the new natural norm.

        Correct

        Natural selection happens at the genotype level, not the individual level. Having a species that likes to combat with other individuals with, essentially, the exact same genotype, at the expense of both individuals, is often not a winning strategy.

        (There are exceptions and caveats of course – e.g. competition between individuals to select the fittest ones of them to preferentially survive, or Fisher’s Principle which explains why the ratio of males to females is roughly 50:50 in most species, even though that’s often not optimal for the species as a whole).

        Man, that’s some crazy logic. I’ll take occams razor and state that wind movement abrades the leaves/limbs on one another.

            I’m just saying you’re adding too much complexity in this particular phenomenon. Evolution by natural selection is a very robust model that has remarkable predictive power. It only works if you’re not assuming too many inputs.

        And isn’t it advantageous to the whole forest if the mature trees are the same height? Doesn’t that happen naturally all over the place? Something about equal sunlight, hydraulic pressure, hydration, and… I forget.

          It’s advantageous to be a taller tree than your neighbours, since you get more sun. That turned into an evolutionary arms race to the top, and now we have tall forests.

      I’m no expert, but plants could all begin growing at the same time in nature thanks to things like wildfires, landslides, etc.
