Isn't that the tree owner's decision? Fully disclose all alternatives and let them pick. If you try to steer them toward removal based on your perception of their economic and other values, you may find that they have values you'll never understand. You may also lose credibility with them by showing bias.Mike Barcaskey said:you just remove the lead to "prolong the life of the tree and delay that final day" you are definetly not working in the homeowners best interest
I don't know which seminar you heard that from; many different presenters at ISA sessions have different backgrounds and will present them differently. Arborists facilitate the coexistence of trees and people; to me this does not mean removal is the first resort. Read http://www.treesaregood.com/treecare/mature_care.asp
For an arborist, removal seems to be the last option.
"Peer-reviewed" does not mean there is no disagreement among individual presenters, that I can personally promise you. Besides, nO one strategy fits every tree situation, that's what makes it so much fun!
