Tasmania's Giant Ash Trees May be the World's Tallest

While the majority of people (at least us native Californians) have heard of the towering redwoods found in Northern California, no one talks about the giant ash trees of Tasmania. Found in, you guessed it, Tasmania, ash trees are the tallest flowering trees in the world. While they aren't the world's tallest (beaten by those pesky redwoods), research suggests that they could have been if it wasn't for climate change and humans. While ash trees were thought to live for only 350-450 years, recent studies show that they could live past 500 years and although this doesn't compare to 3,000 year old redwoods, ash trees grow an astonishing 5 times faster than their California Counterparts. Like many other species in Tasmania (disregarding natural causes such as fires, fungus, and climate change), Ash Trees faced dire consequences with European colonization. Logging severely reduced ash tree populations, and today, only a tiny percentage of these trees that were alive in pre-European Tasmania are still standing. One can argue that these trees are as tall as redwoods; they'll just have to wait 100 years to see their true potential.

  1. Heh, growing up in Sonoma County, CA I've always felt a bit of pride in our redwoods - looks like they have some competition!

    I'm curious about what this means for forest succession. Because they are so big, fire resistant, and live so long, redwood forests are some of the most stable ecosystems (at least when people aren't cutting them down). Since Tasmanian Ash trees have such a fast growth rate, could ash forests be adapted to withstand more frequent disturbances? That could be good news for forest regeneration! - Aaron

  3. Very interesting! I wonder why it is that climate change impacts their growth. It's also interesting that the Ash Tree grows 5x faster than Redwoods, it makes me wonder what kinds of things are taken into account with the maturation of these huge trees. I hope we get to see some of these when in Tasmania, it would be great knowing that we might be seeing, potentially, the tallest trees!
