Ohia trees are dying rapidly, Why?

[bgiles]

Here in Mt. View, 1400', most trees look VERY healthy. That's why it's disconcerting to see a healthy tree die in a very short period of time, with intact but desiccated leaves. Now I have entire branches on two trees dying, but they're on trees with "co-dominant" trunks, meaning largely separate root systems. No traumatic root damage; last bulldozer was on property over 15 years ago.

Excise branches, then burn?
