The question of what to call a professional who works with trees often leads to confusion due to the many specialized roles in the field. While terms like “tree surgeon” are sometimes used informally, they do not accurately describe the full range of expertise involved in modern tree care. In fact, a variety of titles exist for individuals who dedicate their work to the health, management, and study of woody plants. Ultimately, one specific title serves as the primary and most comprehensive answer to this common query.
The Primary Professional Title
The most appropriate and widely recognized title for a tree professional is an Arborist. This term, or the less common but related Arboriculturist, defines a specialist focused on the cultivation, management, and study of individual trees, shrubs, and other woody perennial plants. Arborists concentrate on the health and safety of trees, particularly within urban or managed landscapes where trees coexist closely with people and infrastructure.
Arboriculture is the practice that focuses on the individual tree, distinguishing it from the broader management of forests. The International Society of Arboriculture (ISA) is the leading global organization that establishes standards and provides credentials for this profession. Certification from the ISA indicates a recognized level of knowledge and dedication to proper tree care practices.
Scope of Practice for Arborists
An arborist’s work is largely centered on the practical application of tree science to ensure plant health and public safety. A significant portion of their practice involves performing specialized pruning techniques, which can range from structural pruning on young trees to crown reduction on mature specimens. This work maintains plant health and mitigates potential hazards by removing dead, diseased, or poorly attached branches.
The evaluation of tree risk is another core responsibility, where arborists assess a tree’s structural integrity and its potential to fail and cause damage. They are also experts in Plant Health Care (PHC), diagnosing and treating specific diseases, pest infestations, or nutritional deficiencies affecting individual trees. Furthermore, an arborist advises on appropriate tree species selection, proper planting methods, and tree preservation strategies, especially when trees are near construction sites.
Related Tree Specialists and Their Focus
The field of tree work includes several other professionals whose focus differs significantly from that of an arborist. A Forester, for example, is primarily concerned with the management of entire forests and tracts of land. Their work involves large-scale ecosystem health, the sustainable harvesting of timber resources, and the protection of broad forest areas from fire and disease. The forester manages a population of trees, whereas the arborist manages the individual tree.
A Silviculturist focuses on the practice of controlling the establishment, growth, composition, health, and quality of forests. Silviculture is considered a component of the broader field of forestry, dealing with the art and science of growing and tending forest stands to meet specific management objectives. This role is more about the long-term culture of the forest for diverse needs and values.
The role of a Dendrologist is primarily academic and scientific, focusing on the study of trees and other woody plants. Dendrology is a branch of botany concerned with the taxonomic classification, history, and identification of woody species. Unlike arborists or foresters, dendrologists are researchers who study the biology of trees without necessarily engaging in hands-on practical management or commercial applications.
Becoming a Certified Arborist
Achieving the designation of ISA Certified Arborist requires a combination of practical experience and demonstrated knowledge. Applicants must typically have at least three years of full-time, practical work experience in arboriculture or a combination of experience and a relevant college degree. An associate’s degree in a related field, for instance, can reduce the required work experience.
Once the experience requirement is met, candidates must pass a comprehensive examination covering a wide range of arboricultural topics. This 200-question multiple-choice test assesses knowledge across ten domains, including tree biology, soil management, pruning, and tree risk assessment. To maintain the credential, certified arborists must adhere to a code of ethics and participate in ongoing continuing education to ensure their knowledge remains current with industry standards and scientific advancements.
