TREE CLASS REFERENCES

As I was researching prior to my first-ever class on trees, I had to limber up my brain.  There is a forest of facts we now know about trees beyond the elementary biology back when I was in school.  Then it was layers of bark, photosynthesis and roots. We now know that every living tree trunk is NOT a single tree but often just one sprout off a long-lived, wide-spreading root system that may have many trunks, even a grove of trunks.  If the root system is healthy a cut, wind-felled or burned trunk may simply lead to more new growth above the ground.moon

So here are some of the sources I saw and from which I harvested information.  There is much online where you can root around.  You can leaf through an orchard of books, many new and some venerable.  Trees can now be seen as a rich branch of knowledge: from legend and folklore, to forest bathing and self-therapy, to science, and down into profit-mongering orchardry.  This world of trees is our world, and we are in theirs.  It seems highly unlikely our species would survive on a planet devoid of trees.
Herewith some of my sources:
