It’s a complicated series of factors including climate and species; [here’s a good writeup](https://www.nature.com/scitable/knowledge/library/global-treeline-position-15897370/), including a best fit chart of tree line altitude by latitude.

Edit to add the customary thanks for my first gold; I’ve never felt so much power!
