There are islands and bushes all over the map. Sail to an adjacent island, set up a portal, and mark the cluster(S) of bushes. If you find an exceptionally large patch put a stake wall around the clump. Then build a permanent portal somewhere in the middle of all those clumps. When you have good gear in an early biome just use all stamina foods. I'll do a berry run while I'm smelting if I need some kind of berries.

I kind of worried the same about bee hives but after I got 12 of them built and found another 20 queen bees I realized that they were every where and I would just have to look if I needed more.
