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.
