I’m jumping in kind of late on this one but I’d like to pitch in on two cents.
The #1 item in the jungle is the machete, provided you also have a file to sharpen it. The machete is used to clear trail, clear campsites, build shelters, harvest food like palm hearts etc.
The hammock is far and away the best shelter for the jungle but if you aren’t planning to move you can make a kickin’ shelter with a full day’s work in the jungle. Where I live you can cut down Imbria trees and strip off the inner bark for very strong lashings. The poles are very straight and can be lashed to trees to make a raised bed. The important thing is to get off the jungle floor.
If there are water filled vines or bamboo in the area you can drink this water without treatment. If those types of plants are not available you have to have some way to boil or treat your water. You can boil water in sections of large bamboo but that would be a huge pain to keep yourself hydrated.
Fire is a major problem if you are in the rainy season. Most tropical jungles suffer from high heat, humidity and daily thunderstorms even during their “dry” season. People who make friction fire in such places take special care to keep their materials dry.
