Aloha,
These trees are very invasive and wreaking a lot of havoc on the island, I would like to help reduce their impact and their numbers. Let's start at your property!
I had a lot of these at my property here in Pahoa, and have a lot of practice at how to reduce these nuisance trees and other ones as well.
If you are trying to go this route, I have already bought the expensive poisons (milestone & crossbow) for Albizia & African Tulip.
I have chainsaws and climbing gear depending on their size, safety is priority, but I will try to help with what I can.
