Cabling/bracing
reduces the risk of tree failure resulting from:
structural
weaknesses (V-shaped crotch)
storm
damage
mechanical
injury
rubbing
limbs
long
heavy limbs
Aftercare
Properly
installed cabling systems are unobtrusive. But "out of sight" can't mean
"out of mind." Cabling systems should be professionally examined once
a year and after each major storm. A climber should inspect the system
every five years.
Bracing is normally done as part of an overall cabling system, mainly
to add strength to a weak "V-shaped" crotch.
