Redwood is primarily used for the chunks/chips that are used because the
redwood has a chemical in it to try and suppress other species seeds from

I wonder if that might be where they get that playground chip stuff
that they used to call "tan bark" or maybe "tanbark"?


That stuff is mostly bark, but not from this tree. Primarily conifer.

Tan oak was a major source of vegetable based tannin, until around the turn
of the twentieth century. Then other processes and sources made the
economics less attractive.
