I would also include a demonstration and skill set that shows proper care and respect for trees.
- determining a proper minimum diameter to hang from
- demonstrate proper height of tree hugger to minimize stress on a tree
- explain the benefits of tree huggers and their proper use
- different types of barks and how they might be affected by hammocking
- overall general care and consideration for trees and their role in the environment
and... +1 on the pros/cons of hammocking as well as tent camping and how they benefit/are risks to the user and the environment.
another +1 on first aid to hammocking related injuries.
I would LOVE to see a push/movement to an official Hammocking merit badge. I'm Scoutmaster for Troop 1567 in Utah National Parks Council.
I strongly believe that there is a misconception of hammocking and its effect on environment. It might be a two-part reason; 1. some hammockers don't know how to hang properly; and, 2. the policy makers are making decisions based on those hammockers.
If we can get a movement/effort moving forward in our youth that demonstrates they know how to and respect the trees through proper demonstration of hammocking, then maybe the barriers that ban hammockers from some areas can be removed.
