Many of the tree doctors in Buffalo, NY now employ ISA Certified Arborists to take care of their client’s trees and shrubs. An ISA Certified Arborist has demonstrated a high level of knowledge about trees and tree care by passing an extensive exam developed and administered by the International Society of Arboriculture.
The ISA Certified Arborist exam assesses a tree doctor’s knowledge in six main areas of tree care:
- Tree biology
- Tree identification and selection
- Tree installation and establishment
- Soil management
- Tree pruning, tree diagnosis, and tree protection
- Tree risk management
