What is interesting is that plant communities diverge and converge over 100k+ year timeframes. The boreal or what have you might have looked a bit different in terms of composition a few 100k years ago. Most env. Scientists (myself included until I learned this) tend to think of ecosystems as relatively static, but that’s not the case. They, like the organisms they contain, adapt to external pressure, or die.
