Agreed with all Boa said.
This is how the species would develop naturally. Its rare to find one that hasnt been buggered with to fit in with humans needs/wants for clear space.
Once you remove those low branches, the next layer above are more likely to fail. I believe theres a bit of "teamwork" amongst the canopy, protecting each other etc.
at Boa, 3hr walk! Its not that far from anywhere if ya know where your going!
