Nice post. I have collected lodgepoles in the Cascades, both larger ones and smaller ones and have found them very durable to collection. I have seen the same things seen elsewhere in this thread, i.e. additional enthusiastic flushes after fertilization as well as very good back budding, especially on laid flat / descending branches.
Also as
@parhamr mentioned upthread a lot of Cascades-collected lodgepoles seem to be infected with dwarf mistletoe, but it doesn't seem to have much in the way of negative effects on their health (though may depend on how far it's progressed). Out of morbid interest I actually collected one of these mistletoe-infected lodgepoles a year ago, chopped the mistletoe off and let the tree recover in a basket with a mix of larger pumice and native soil from the collection site, fertilizing regularly starting in mid-spring. It responded with a considerable amount of budding and I've got roots popping out of the bottom of the basket. No return of mistletoe yet.
