I have seen adult, trunked Howea palms removed for trivial and incorrect reasons. In my neighborhood there once was a home for sale, featuring two Howea forsteriana palms perfectly sited at the home entrance, one on each side of the foyer. After the house was sold, they were cut down immediately.
My palm mentor, the late Garrin Fullington, rang the doorbell and inquired "What happened to those palms ? I was going to offer you $2000 for each one."
At a church on Guerrero street there was a planter bed about 5 x25 feet. It has a H. forsteriana, about 8 or 10 feet of trunk, at one end. Some plant on the far end was diseased, and the gardener recommended that all the plants be cut down. ( I know this story because I asked the sisters myself.)
