Arborist
ArboricultureA trained professional who specializes in the care and maintenance of trees, including planting, pruning, diagnosis, and removal.
An arborist is a specialist in the cultivation, management, and study of individual trees, shrubs, and other perennial woody plants. Unlike general landscapers, arborists undergo specific training in tree biology, diagnosis, maintenance, and safety practices. They are qualified to assess tree health, recommend treatments, and perform complex operations like canopy work at height.
Hiring a certified arborist is essential when dealing with large or hazardous trees, diagnosing mysterious decline, or planning construction near established trees. They can identify early signs of disease or pest infestation that untrained eyes would miss, potentially saving a tree that might otherwise be lost.
When selecting an arborist, look for credentials from the International Society of Arboriculture (ISA). A reputable arborist will carry liability insurance, provide written estimates, and never recommend topping a tree. They should be willing to provide references and explain their recommended course of action in terms you can understand.
