Arborists Are Bringing the 'Dinosaur of Trees' Back To Life (qz.com) 148

Arborists are cloning saplings from the stumps of the world's largest, strongest, and longest-lived trees -- felled for timber more than a century ago -- to create redwood "super groves" that can help fight climate change. "Using saplings made from the basal sprouts of these super trees to plant new groves in temperate countries around the world means the growths have a better chance than most to become giants themselves," reports Quartz. "Their ancestors grew up to 400 ft (122 m) tall and to 35 ft in diameter, after all, larger than the largest living redwood today, a giant sequoia in California's Sequoia National Park." From the report: Already, super saplings from the project are thriving in groves in Canada, England, Wales, France, New Zealand, and Australia. None of these locales are places where coastal redwoods grow naturally, but they all have cool temperatures and sufficient fog for the redwoods, which drink moisture from the air in summer rather than relying on rain. [David Milarch, founder of the Archangel Ancient Tree Archive, a U.S. nonprofit that propagates the world's largest trees] calls this "assisted migration." Last month, his organization planted another such grove in the Presidio in San Francisco, California. The park lies along the U.S. west's redwood corridor, which runs from Oregon to California, home to the stumps the saplings were cloned from. But 95% of giant growths there were cut long ago. Many of the redwoods along the corridor now are young trees. Milarch notes that as the local climate is getting hotter and less foggy, it's no longer as conducive to producing the mega growths of yore. Now, 75 saplings created from the basal sprouts of the most rugged and massive ancient tree stumps of the coastal region will grow in the Presidio. They may eventually become the hardiest and tallest trees around, if their ancestors are any indication.

    The particular trees are less important.

      Less important, but not unimportant: Thanks to their huge size & height, a square mile of mature redwood forest would be capable of sequestering a LOT more carbon than a square mile of any other type of forest..

      (although counting biomass-per-year, rapid growing, shorter lived tree like poplars wouldn't be bad in the short term either)
      • Redwoods ARE fast-growing trees, like many conifers. And you can readily "sequester" the carbon in decks, fences, conference tables, etc. And then grow more...

      Right. Something to consider before planting non-native trees and potentially destabilizing the local ecology. But sure, go ahead plant tall, fast-growing redwoods that will take over the local tree canopy within a matter of years. What could go wrong?

      • And we all know that stability is the ultimate goal. Life should never have been allowed to start on Earth, polluting the pristine lifeless environment.

        Most environmentalists are fools or worse.

    To de-mystify:

    Scientists are planting samples of giant Californian Redwood Trees, around the world in appropriate climates.

    Global warming means California is no longer the best environment for them, so they are hand picking locations where it is the best environment.

      They said "dinosaur" just to get everyone's attention, but this is more like a selective breeding of an existing species, and transplanting into alien habitats, which may or may not result in more big trees.

        With most large species, the same thing that makes them big also makes them specialists. And they tend to be most prone to dying off with slight changes, because the environment changes faster than they can evolve - a problem simple and small organisms don't have. There's no particularly good reason to think that just because these trees grew old and huge under ideal conditions that they are any better at tolerating less-good conditions (like getting transplanted 12,000 miles away in a different hemisphere).

            We'll see, I guess, in about 2000 years...

        They said dinosaur, climate change, clone, "super grove", "super trees," and probably giant redwoods to get everyone's intention.

        It's hard to know what these people are actually trying to accomplish. The trees didn't die out because of climate change, their population was reduced because of logging, and there are lots of them growing now (mostly not as big, though). All up and down the coast of California, and even in the Sierra's, there are plenty of places for these trees to grow, and where they are growing.

        I'm not saying you're wrong but redwoods do have an impressive trait or two beyond height. The same bark that requires exposure to moist air also makes them mostly fire retardant. At least in the context of the type of fire present in wild fires.

        I had my Ian Malcolm lines all set up, "this wasn't some tree killed by deforestation"... Well fuck me, it was.

        Serious note though... As someone who was born in Australia the flagrant introduction of species into different environments can be devastating to the local wildlife. I know the idea is to save the Sequoias which are endangered, but we need to be careful that introducing them to foreign habitats isn't done at the detriment to that habitat (destroying the habitat may also be detri

        • You have a point, but It takes 2000 years to grow to full height. I don't think it's that much of a risk compared to rabbits or cane toads. Plus, it's probably not going to work in any case, they evolved to work in a very specific, rare (bordering on unique), habitat, and most of Australia is *utterly* incompatible. I don't see much danger of being overrun.

          If it was paleozoic glossopteris, then it would be more of a concern. They are about at close to managing that as they are T. Rex.

    • by tomhath ( 637240 )
      These aren't really scientists, mostly just a bunch of tree-huggers. And the surviving Coast Redwoods are doing fine along the coast of Northern California (which is still the best locale for them). They're endangered because most of the old growth was harvested a century ago and California doesn't manage the existing stands very well, but new ones continue to grow there anyway.
      • The more the merrier, I say. Redwoods are cool. They look like something from fantasy. I'd like to see them all over. I was just 5 when my family went west for a vacation (this was the 1960s) and visited CA, CO, AZ, and UT.. I remember.. just barely.. the giant redwood you could drive through, it was one of those things that left an indelible impression from so long ago.

    • it's still has the best environment which is shrinking

      they always did grow in relatively narrow band with the proper conditions.

      I don't see them faring well anywhere else. the big trees in california are 2000 - 3000 years old, these transplants might do okay for the first century or six....

    I like having giant trees again, even though I will be dead long before they reach max size.
    But these things grow slowly and are not the best at carbon capture.
    Plant some bamboo or some other fast growing tree if you want that.

      It's not just absorbing carbon, but also sequestering it. These will live quite a long time and mostly just need to be left alone to do their thing.

      If these guys want to try tackle the problem this way, may as well let them. If you've got other ideas or a different approach, then you should be free to do that. Sure this isn't going to magically solve everything overnight, but it's better than just sitting around expecting someone else to do something. It's also kind of cool in its own right, so who cares if you think they have silly motives.

      Because redwoods actually require forest fires to properly open their pine cones. Without that heating the majority of the seeds will never properly germinate or be released from the cones, causing them to be eaten, decomposed, or be outcompeted long before they can become a threat to local flora.

      Having said that, my real question is: 'Why aren't they selling cuttings of these in their store for local restoration in central/eastern California. You know, the NATURAL RANGE for Redwoods/Giant Sequoias? Persona

        As TFA explained:

        Milarch notes that as the local climate is getting hotter and less foggy, it's no longer as conducive to producing the mega growths of yore.

        So their natural habitat is no longer the way it was. The saplings will not grow that easily where their ancestor stood of which they are clones.

    • by dfghjk ( 711126 )

      No, because they are inherently not "invasive species" nor should the be "removed immediately" because they're being put there deliberately.

      You know, some conscious thought is required when stringing together words that you've heard before.

  • They may eventually become the hardiest and tallest trees around, if their ancestors are any indication.

    Tallest, yes, but hardy implies that they can endure difficult conditions. If they struggle to endure reduced fog in their native habitat this suggests that they are not particularly hardy.

    They take 3-4k years to grow, and from what I've seen of sequoia trees, they have few branches and few needles to photosynthesize CO2. Surely smaller. faster growing, more leaf/needle sprouting plants such as bamboo would be faster at sucking up CO2.

      Yeah, I think you're off by a bit there. Redwoods grow a few feet per year, some varieties as much as six feet. It may take 100+ years to grow a 400 foot tall redwood. It's more likely these will grow for less than 100 years and top out at 90 feet, which is what typically happens when redwoods are cultivated.

      To create a biological carbon sink, you need plants that will live for a long time and resist decay. Bamboo grows fast, but sequesters carbon for a decade or two. Trees like redwoods sequester carbon f

    • They take 3-4k years to grow,

      These are the coast redwoods. Their maximum lifespan is about 2000 years, and most don't make it past 800. They tend to topple in storms around that time, like the Dyerville Giant that toppled in 1991, which is when they discovered it had been the world's tallest tree. It was 1600 years old though.

      The article, to me at least, seemed to be a little fuzzy about whether it was discussing giant redwoods vs coast redwoods. Giant redwoods do not actually grow in the coastal fog zone, so it was kind of confusing. Giant redwoods tend to be found in the Sierra Foothills. They are the most massive trees in the world, and live potentially for a few millennia.

      But coast redwoods actually grow taller than giant redwoods. They grow pretty fast and live for hundreds of years (still not too shabby). This is exactly w
