Arborists are excellent problem solvers. They are well educated about
the botany of numerous species of trees and the unique needs of each one.
Arborists also take into consideration the life cycle of each tree, and its
symbiosis with the organisms in its immediate ecosystem, including humans. With
the inescapable power and telecommunications lines placed both overhead and
underground, a talented arborist must effectively plan and maintain the
planting and growth of just the right type of tree for a client's purposes.
Arborists are both artists and scientists. http://www.bls.gov/opub/ooq/2001/spring/yawhat.htm http://education-portal.com/articles/Arborist_Job_Description_Duties_and_Requirements.html
