Arborist

An arborist, also known as a tree surgeon or arboriculturist, is a professional in the practice of arboriculture, which is the cultivation, management, and study of individual trees, shrubs, vines, and other perennial woody plants in dendrology and horticulture. Arborists focus on the health and safety of individual plants and trees, rather than managing forests (the domains of forestry and silviculture) or harvesting wood.

Qualifications and Duties

Arborists typically hold qualifications from colleges or technical schools in the fields of arboriculture, horticulture, forestry, or environmental science. In some countries, arborists must be licensed to practice and may require continuing education to maintain their certification. The duties of an arborist include planting, pruning, structural support, preventing or diagnosing and treating pest and disease problems, and sometimes tree removal.

Pruning

Pruning is a significant part of the job, aimed at removing dead or unnecessary branches to improve a tree's structure, enhance its health or appearance, or reduce risks due to falling branches. This is critical for the safety of the public and the preservation of trees in urban environments.

Tree Removal

Although tree removal is seen as a last resort, there are circumstances when it is necessary. An arborist can help decide whether a tree should be removed. Arborists have the skills and equipment to safely and efficiently remove trees. Removal is recommended when the tree is dead, diseased, or poses a safety risk.

Emergency Tree Care

Arborists also engage in emergency tree care, which can involve removing trees or branches that have fallen on homes, vehicles, or other structures during storms. This work can be dangerous and requires a high level of skill to avoid further damage to property or injury to people.

Consulting and Legal Services

Experienced arborists may also provide consulting services, offering advice on tree preservation during construction, assessing tree health, and providing legal testimony on tree-related cases.

Professional Organizations

There are several professional organizations that arborists can join, such as the International Society of Arboriculture (ISA), the Tree Care Industry Association (TCIA), and the American Society of Consulting Arborists (ASCA). These organizations provide members with access to continuing education, certification programs, and industry conferences.

Challenges

The work of an arborist is physically demanding and can be hazardous. Working at height, often in close proximity to power lines or in difficult terrain, requires the use of specialized equipment and safety protocols. Arborists must be knowledgeable about a wide variety of tree species and their specific care requirements.

Environmental Impact

Arborists play a key role in maintaining and enhancing urban green spaces. Their work contributes to the health of the urban forest, providing numerous environmental benefits such as improving air quality, reducing urban heat island effect, and supporting wildlife.
