Do you ever feel bad about cutting down a tree?

They do make a lot of productive progress in those 40 years…I have a few oaks that could have become a saw log 35 years ago and they have not gotten that much bigger.

Black walnuts grow at a faster clip in their youth…from 3 to 10 feet in no time…even 10 to 25 can be amazing…but they do not go from 25 to 50 anywhere nearly as rapidly. (But, if you are measuring total mass of a tree, the added mass yearly of a 35 year old black walnut or a 50 year old one in some cases can be phenomenal…and the dense black hardwood core increases in proportion to sap wood in these old walnut trees.
