When I was a kid I saw a lot more birch trees than I’m seeing now. Not sure why that is.

The bark peels off from birch trees fairly easily without harming them. More aggressive means can remove large sheets from healthy ones without killing them. Once done the uses are many. Otzi the iceman made his arrows using the tar, made by cooking it in an oxygen-free container.

Birch bark is also excellent tinder.

Thanks Sunken - new word for me an my kids: “Hafting” - “Hafting is a process by which an artifact, often bone, metal, or stone is attached to a haft (handle[1] or strap).”

A huge development for humans, but I don’t know of any animals having been shown to do it (but many do use simple tools).

There are indications that the Neanderthals used this glue formula up to 200,000 years ago!
