Ohia trees are dying rapidly, Why?

[Guest]

Here is an updated article on how our Ohia forests are doing, pretty sad to watch the last 6-8 years. Looks like it has continued to spread quickly from lower puna to most parts of the island.

Its looking like we may never know what caused this (ROD) to start, although they do think leilani is ground zero.
Maybe a coincidence that helco and ormat were expanding a multi million dollar business that required (drilling, dozing, driving, adding power lines, and tree cutting,) in lower puna when this ohia wilt started. Also another coincidence is that Ormat owns and operates the very large geothermal plant near Mammoth lake in California. Where they have been battling the black oak wilt fungus for some time now. Concern here, Could This ROD fungus hitch a ride or stay alive long enough on a truck, tool, or on some drilling equipment from that Mammoth lake area? Wondering if the two deadly strains of fungus have been looked at for similarities, or if by chance one or the other has any effects on the others host tree oak or ohia?.
