Studying trees to become Oakwise
I was recently reading The Book of Druidry by Kristoffer Hughes. In chapter 8 they suggest studying one tree per year with the goal to be "oakwise" withing 20 years.
Sounds great! I love trees, yet don't know a whole lot about them. How do I study them exactly?
One step I've taken is identifying a specific tree on iNaturalist (Pin Oak) and I've collected fallen leaves of different stages/colors, fallen bark, and will collect the acorns that drop when its their time. I want to flatten the leaves and put them in my book of shadows. And who knows what I'll do yet with the bark and acorns.
I'm no botanist, and I've never been great at research, so I'm looking to see... Has anyone done this before? Where would you recommend I start?
