Climate difference in Fern forest vs Hawaiian acre

[Greenreef]

I've been looking at moving to the bIg island for a few years now and the date is set, I'll be there in two weeks. I'm well prepared, done a fair amount of research and have a realistic outline for my first year or two but I know there's a difference between experience and information. I'm looking into Hawaiian acres and Fern forest as the main two communities I'm interested in buying in but others are not out of the question. I'm curious with the elevation and temperature change what fruit trees wont grow very well in fern acres. I know coconuts won't and I don't mind that. I'm more curious about fleshy fruits like papaya, barbbedos cherry, bananas and plantains, bread fruit, avocados and citrius. Anyone with experience growing these in fern forest please chime in. From what I've seen online most rentals are in the lower elevations and experiences may not translate one lot to the next let alone higher elevations. I don't want to rent for too long before buying and plan on a thorough camp out and survey before buying. Just want to help narrow my search some more and get an idea of what an uper elevation limit I may have to grow what I want. Also as far as garden vegetables go are most fine at higher elevations when in a greenhouse such as eggplant, cherry tomatoes and the like?
