Can you link area where forests are somehow not mappable and cause you to propose deleting tree coverage data from OSM?
You claimed that we should consider deleting tree coverage data from OSM and create a separate project of it (what is mostly offtopic in this thread). I responded that forests are mappable in OSM. And poor data quality in an unspecific location is not a good reason to do something like that. Why proposing solution for the problem would be ignoring it? Hard to say more or verify without getting specific location but I cleaned up some places mangled by badly done forest imports - for example border area that was hit with multiple low quality imports. But it sounds exactly like https://www.openstreetmap.org/user/Abbe98/diary/28368 that was solved by splitting unreasonably large relation in parts (by deleting it and remapping) And yes Canada is large and we may never finish mapping forests. It does not mean that we should delete all forest data. We will also never finish mapping shops, opening hours and many other things.
