What are the leaves like on your ohia? That indicates the type more than the form of the trunk. The first type to come up on the lava flows has densely hairy leaves; these are eventually replaced by a form with bare leaves (there are also hybrids, which have fewer hairs that you can rub off relatively easily with your fingers, but these don't do as well so they're not as common). If the ones dying are the hairy-leaved form and the ones surviving have bare leaves, it might just be natural progression.
Unfortunately the ohe mauka (Tetraplasandra hawaiensis) are dying out around Leilani. There seems to be another type of fungal rot that kills them, turning the inner bark to slime. They're also sensitive to injuries, which may be how the fungus gets in. One landowner I talked to there said he had been told by the guy who cleared his lot that they were weeds! There is at least one planted on the UH campus, but I don't know if it's big enough to make fruit or if it will do so at all without another one around.
Ohe makai (Reynoldsia sandwichensis) prefers drier places, there were some around Kalapana but it's probably too wet in most of the subdivisions.
