Ohia trees are dying rapidly, Why?

As there is noting "endemic" to Hawaii, the Ohia also travelled here. It came in the stomachs of birds on the jet stream. The seeds evolved on their way here and the tree further evolved to the Big Is;and's unique stressors. As far as I know, it is the only tree that can stop "breathing" during times of high SO2 from the volcano. Koa came the same way, most likely from Tasmania where its very close cousin, blackwood is from. Old koas in the park are also dying off as they live about 700-800 years. But there is also drought to consider as well as the worst invasive in the area, the fiya tree. I think there are many stressors on the ohia now that are causing them to die. It is very disturbing to me to watch.
