Study on bark damage?

This is related to Knothead's challenge to use cambium protection. The issue also came up in a hammock camping forum (debating if the ropes used to hang a hammock do bark damage).
Does anyone know of any research that has been done about cambium damage or resistance to rope injury? Or are there official guidlines that have been established for arborists in regards to tree protection?

Research on cambium damage or resistance to rope injury is limited, but there have been discussions in forums, like a hammock camping community, regarding the potential bark damage caused by ropes. Official guidelines for arborists may vary, but they often emphasize the importance of tree protection during activities such as pruning or rigging. However, specific protocols for mitigating cambium damage from ropes may not be universally established.
