In some places it might. And i guess in a sense all forests are managed…

But yeah paper comes from trees. Trees grow in forests. Sawmills sell a lot of their chips and sawdust to pulp mills.

I’m pretty sure (most of?) the patches of boreal forest in question are managed.

Boreal just means northern and not the coastal rainforests or something. Y’know, the trees we have an almost endless amount of.
