|Dawn Redwood (Metasequoia glyptostroboides)|
Here are some of my pictures of the single specimen at the Göteborg Botanical Gardens. It was exciting when I found it there on my first visit ever to the Botanical Gardens. Prior to the visit I had been researching Metasequoia as a result of the uncovered giant trees found at the north pole on Axel Heiberg Island some couple decades back and the studies of not only the tree, but also what the climate was like to have such an incredible forest of these giants along with countless other biodiverse living organisms. There is a large stump field right where the trees actually grew after what was described by some as a mega-tsunami which destroyed life there by snapping the trees off their trunks and burying them under massive amounts of sediment which apparently flash froze. Sounds like a "The Day After Tomorrow" scenario of sorts doesn't it ? They estimate in an area called the Buchanon Lake Formation there are some 10,000+ logs and other debris buried there. But the truly amazing thing is that the evidence of this ancient world is still somewhat fresh. The wood still burns and so would the cones, leaves, twigs and branches they have unearthed as a result of further global warming revealing this treasure. None of this is petrified wood as in other fossils caches. Just extremely well preserved organic matter. I'll post a further references pages on this subject below.

The photo above insists that this is a 50-million-year old tree stump which lies exposed on Axel Heiberg Island, where Nunavut may establish a territorial park. I'm skeptical as to an actual 50 million years old without anything happening to cause decay. But the prevailing ideological philosophy holds the power of the print. Below is a photo of the stump field on the hillside. Notice the lake terracing effects of the gradual receding waters which were no doubt followed by snow and glacial build ups. One can only imagine how such an enormous extinction event not only wiped out all the rich biodiverse ancient life for good, but also entirely changing the weather dynamics permanently which presently prevents a re-occurrence of such life again.

This tree would be a challenge to grow in many of the drier locations on Earth, but possible given enough water and the proper biological organisms makeup of the soil they are in. The Los Lunas, New Mexico Nursery "Trees The Please" which is just south of Albuquerque is an excellent example of growing such trees in an otherwise challenging soil and climate environment. Please review some of the important and informative links below for further understanding of proper soil requirements and the ability to change saline and badly alkaline soils into a rich forested habitat by using biological processes which have the ability to digest, redistribute and to recreate the Earth into something extremely productive. Keep in mid that not everyone is on board with turning wastelands into natural productive ecosystems. Many environmental groups become viciously indignant aat the very thought of changing the status quo of any untouched wildland for the better. The Center for Biological Diversity in Arizona and one of it's main leaders and spokeman, Kieran Suckling viciously attack author, Fred Pearce, who wrote a wonderful piece in 2013 about the transformation of a true desert island, Ascension Island, where over the past 100+ years sailors & a well known British Botanist had brought and planted various plants on the bare island which moved up the mountain slopes and created a cloud forest. Previously little rain fell, but now they get precipitation and running streams where there was once nothing. The reason for the environmentalist anger ? They claimed certain native lichens, mosses and other small perennials would be wiped out and if Nature wanted a forest there, it would evolve one. This is complete nonsense. I was attacked by the Southern California Desert Protective Council who were livid that I would mention turning lifeless badlands into protective native plant ecosystems. There are many groups out there who think they know Science and what Earth needs, but the reality is they are mainly obsessed with a political ideology and worldview that views humans as a threat to the natural world. Of course they never view themselves as part of that threat, but only it's answer. In any event, I hope this spotlight on Metasequoia and how much humans have to go as far as learning about nature need to go.
