Arborists play a crucial role in maintaining the health, safety, and aesthetics of trees and woody plants. They manage individual trees rather than forests, with work including planting, pruning, treating diseases, and ensuring safety. Arborists require specific training and certifications, with education programs available in many countries. They adhere to professional standards that protect trees' health, providing solutions through cultural practices like proper pruning techniques.

A tree surgeon, also known as an arborist or less commonly, an arboriculturist, is a professional
who plays a crucial role in maintaining the health, safety, and aesthetics of our natural
surroundings. With a focus on individual trees, shrubs, vines, and other perennial woody plants,
their role goes beyond forestry or logging to include the care and management of these crucial
components of our ecosystem.
A Unique Field of Expertise
Arborists provide a critical service in urban and rural settings. They manage and study trees in
dendrology and horticulture, maintaining a focus on the health and safety of individual plants
rather than managing forests or harvesting wood. An arborist's scope of work varies from that
of a forester or a logger, encompassing a range of activities from diagnosing and treating
diseases to planting and pruning trees.
Working in diverse ecological settings, arborists also monitor and treat large and complex trees
to ensure they are healthy, safe, and suitable to community standards. This includes installing
lightning protection, removing hazardous vegetation, and dealing with invasive species.
Skilled Climbers and Plant Doctors
Not all arborists are climbers, but those who are employ various techniques to ascend trees, the
least invasive of which is ascending on rope. Safety is of utmost importance, and when
necessary, arborists use spikes attached to their boots to ascend and work on trees. These
activities involve significant technical skills, including the use of equipment like cranes and lifts.
Arborists are also the "doctors" of the plant world. They have the skills to diagnose and treat
tree diseases, prevent or interrupt predation, and manage other factors affecting plant health.
This role often requires them to work closely with power lines and other urban infrastructure,
necessitating additional training or certification.

2. 2
Varied Roles and Responsibilities
The work of an arborist goes beyond just climbing and treating trees. They also provide
consultation services, write reports, and offer legal testimony. This part of their work is often
done on the ground or in an office. An arborist may specialize in one or more disciplines, such
as pest and disease diagnosis and treatment, climbing and pruning, cabling and lightning
protection, or consultation and report writing.
Education and Certification
Becoming an arborist requires specific training and qualifications. This varies somewhat by
location, but often involves gaining practical experience working safely and effectively in and
around trees. Formal certification, which is available in some countries, is pursued by some
arborists. The certification process includes rigorous continuing education requirements to
ensure the continuous improvement of skills and techniques.
In many countries, there are specific arboricultural education and training programs. For
example, in Australia, these are streamlined countrywide through the Australian Qualifications
Framework. In France, a qualified arborist must hold specific certificates delivered by the French
Ministry of Agriculture. Similarly, in the UK, an arborist can gain qualifications up to and
including a master's degree, while in the US, a Certified Arborist (CA) must have documented
experience and pass a rigorous written test from the International Society of Arboriculture.
Cultural Practices and Professional Standards
Arborists are also keepers of cultural practices, providing solutions like pruning trees for health
and good structure, aesthetic reasons, or to allow for human access. This often involves a
thorough knowledge of local species and environments.
Professional arborists adhere to standards that protect the trees' health. For example, practices
like tree topping, which can seriously damage or kill trees, are considered unacceptable. Proper
pruning is practiced with the goal of removing the minimum amount of live tissue. Recent
research has shown that wound dressings like paint, tar, or other coverings are unnecessary and
may even harm trees. Instead, proper pruning, done by cutting through branches at the right
location, can do more to limit decay than wound dressing.
In Conclusion
A tree surgeon's role is multi-faceted and vital to maintaining the health of our environment.
From climbing towering trees to diagnosing diseases and consulting on tree-related legal
matters, arborists are the guardians of our natural world, ensuring that our trees and other
perennial woody plants continue to thrive and contribute to the ecological balance of our
planet.
