The TREE SHADE SYSTEM is a new tree climbing assessment chart with seven classes of difficulty. Each one is divided into three subclasses. Altogether, there are twenty-one subclasses, from Ia (very easy) to VIIc (extremely difficult).
The TREE SHADE SYSTEM is based on five indicators : Structure (tree shape), Height, Access (first footholds and handholds), special Difficulty and Extension (main interval between two branches). A degree from 0 to 4 is given to each indicator according to its difficulty.
