While I agree he should be thinking of some kind of sustainability when logging, I don't think it's his responsibility to coddle the lumberjacks who aren't even offering their services to him.
If they truly had issue with how he went about his work, they should've stepped up and offered advice from the get-go, not go behind his back and hint to his father that they're angry.
Idiots probably could've gotten a Valkyrie or two of their own out of the exchange.
