This colour comes from the bark’s natural structure and chemistry, including compounds such as tannins that help protect the tree from pests, fungi, and environmental stress. The bark also peels in thin layers as it grows, which can make it harder for mosses, lichens, and other organisms to firmly establish on the surface.
That's pretty neat
For me, nature is one of the neatest things on this planet. That's why Rodney and I started Neature Walk. Cause we want everyone to know how neat nature is; instead of just me and Rodney knowin' it.
