Living in an urban forest, ripping up wild young trees is part of normal yard maintenance. I probably get at least a dozen a year. Two of my full-sized trees in my yard were wild seedlings that I allowed to grow because I like those particular kinds of trees (a catalpa and a sumac), and they were in good locations.

This also includes invasive tree species like buckthorn, which is a villain in our area. Buckthorns pop up constantly.
