The idea of rewilding Hawaii makes me laugh. Not on Oahu, not anymore. It’s basically a city, the whole island. it’s too small and there is no local anymore. 95% of the food is imported and those who do grow food locally for the markets are priced out by the strict certification rules that they can’t sell anything in the farmers market or stores.
So I took to the big island of Hawaii and lived in the jungle rewilding for 9 months. It was more difficult than I imagined (and colder too!) Despite what people believe about Hawaii, little of it is true. You do need a coat, and wool socks to live there. A pair of boots wouldn’t hurt either. It rains alot. A LOT.
Wild pig destroyed my gardens, both fenced and guerilla gardens, constantly. If I built a stronger fence, they just destroyed it more violently. They didn’t just destroy gardens, but destroyed soil, plants, streambeds and whatever lawns they could get their hooves on. Sure, you can hunt as many wild pig as you want, and that’s an advantage (and even encouraged) but I get bored after 7 meals straight of pig. There’s also wild goat, wild chicken and abundant fishing. Except for the permitting of fishing poles adn the fact that most beaches where the fishing is good are crowded with tourists and authority figures who will ask you if you have a permit to fish. Gathering is forbidden unless produce is “fallen” and in the road. If it is off to the side, it is still “stealing” to take it, no matter how hungry you are. If it’s in the road, you can imagine what has already happened to it.
Not to mention mosquitoes, which deserve a page of their own as “ecological hazard”.
There are some advantages and yes, tropical places have to be rewilded same as any other, but I don’t think it’s any “easier” than any other place. I left the islands, and now I’m in cascadia too, and there’s a lot here, that’s easier to work with than there, believe it or not. Mostly, dry weather.
