We stopped to walk in a different jungle and pick up some survival tips. I think there would be a lot of things to worry about.
Our guide used the machete to scrape against the tree and these gigantic ants came running out from the ground. These are bullet ants. They contain a neurotoxin in their sting that last for some time.
This is a species of eucalyptus that when cut has a resin that is used to start fires even if the wood is wet. We actually used some of this tree bark to start our campfire on the overnight hike.
A fun hike, glad we did not get close to the bullet ants.
