An RPA can be represented on a TCP plan as a circle, a
polygon or a square. The fundamental shape is
determined by the existing trees root morphology.
A 20% offset can be applied on open grown trees, and
this effectively allows the RPA to be moved depending
on the tree's species and the current site conditions.
The RPA cannot be reduced.
If this is the case, what's is the difference between
using a polygon rather than a circle to achieve the
desired RPA?
Thanks for your comments, Ian.
PS. What does open grown mean exactly? is this 'open'
to interpretation? Or does there have to be cohesion
between canopies etc?
