There is also a state certification for every state in America which is usually a more localized test showing you know plant species and vectors in a given area. Something I think needs to be adopted here.
Ithink the definition needs to give some weight to the fact that an Arborist specializes upon the impact of man and the urban area on trees. We are called to study how urban trees and man interact. Otherwise we would just be foresters.
