Without leave-no-trace straps, hanging hammocks can be very harmful to trees. Thin straps or ropes can cut into their bark or strip it off entirely, which leaves the trees vulnerable to insects, fungus, animals, and the drying effects of wind and sun.
How do you hang a hammock without damaging a tree?
Use Rope. If you have a hammock you want to hang right now, but you don't have tree straps, using a rope is another simple option. You simply need to loop two lengths of sturdy rope around the hammock end-loops and secure them to your trees. It's low-tech, but it's easy to do and won't harm your trees.
Will a hammock kill a tree?
A poorly hung hammock can kill a tree over time as the ropes will eat away at the bark which is the trees protective barrier from insects and disease. If you're camping temporarily, then you don't have much to worry about and can continue to use rope or straps.
