Davies' curiosity led him down a creative path that eventually moved him away from a 12-year marketing career and toward creating content focused on trees. Oddly enough, it's been a great move.

"When I meet new people and tell them I make content about trees, I often get a response like, 'Trees? Really??' with a raised eyebrow, implying I've never thought about trees before in my life, that sounds boring," he says. "But you very quickly discover that it takes almost nothing to help people realize they do find trees to be fascinating. Everyone has a tree they love from their childhood. Everyone has types of trees that make them feel at home. So it's been fun to see that kind of response happen at such a massive scale."

Davies spent around eight months creating his official state tree map, making a video for each piece in which he shares scientific and historical information about each tree, how Indigenous peoples have used them and interesting anecdotes about them. As it progressed, the map project morphed into a community endeavor, with people from all over the country sending him pieces of the kinds of wood he needed from each state to complete it.

Here is Davies sharing the finished map, which is the best place to start. This video offers a glimpse of the work and community support that went into this project, as well as Davies' genuine likability that keeps people coming back.

As Davies said, he isn't actually done. He has also made different countries and Canadian provinces out of native wood, and has started making a whole new larger U.S. map for his followers on YouTube (since the vertical format for video on TikTok isn't really compatible with YouTube).

And to get a taste of what's caused millions of people to tune in each time he revealed a new state, here's the video from the final state he made, Missouri.

Check out Georgia, which attracted nearly 13 million viewers:

And how about Florida, whose official tree is only kind of, sort of a tree (same goes for South Carolina, whose state tree is also a palmetto):

Davies shares that his love of trees goes beyond just their beauty. There's something about trees native to where we live that tap into something primal within us.

"I find them absolutely fascinating, of course. I think they're beautiful, of course. But also from a practical sense, we wouldn't be anywhere without them. We need them to build our homes, to heat our homes, to make furniture, food, the games we play, the art we admire. But ultimately for me, what I love the most is the way different types of native trees and forests have the power to evoke something so personal for different people.

"For me, a large, twisted Utah juniper instantly makes me feel at peace and at home. Same goes for the color of the dancing light coming through the canopy of a quaking aspen grove. I can hear and see and smell those forests and trees that are native to the wild places in my home and they give me something so much different than, say, the exotic beauty of a forest of old-growth redwoods or a cypress swamp. And what I love is how someone from those places will feel entirely the opposite."

Part of what makes Davies' videos so engaging is that he really connects with his audience. Check out how he taps into the psyches of his viewers who were incredibly bothered by the empty space where Nevada was supposed to go before he made the piece.

Davies is thrilled with how people of all ages have responded to his videos. He says he gets sent pictures of things kids made in shop class inspired by his work and messages from viewers who say they didn't care at all about trees before, but who now find themselves out for walks with friends and pointing out things about different tree species. "That kind of stuff is just absolutely amazing," says Davies.

Seriously, who knew trees were so fascinating?

There's something so pure about watching someone do woodworking, but adding an interesting educational element and a true love for trees makes it all the more satisfying. You can follow Justin Davies on YouTube, TikTok and Instagram.
