What Does an Arborist Do?

Arborists are highly skilled tree and woody plant care professionals who recognize the considerable value trees add to life and property. They are called upon by homeowners, businesses and communities to help them protect and maintain their tree investments. An arborist’s career is based on the science of arboriculture, which includes planting, pruning, fertilization, pest and disease control and when necessary, removal of damaged or dead trees.

An arborist will diagnose and provide treatment for tree diseases, insect infestations, structural faults, poor growth, obstructive limbs, soil compaction, wind damage and improper planting. They will also assess the horticultural potential of a site, including the potential impacts of construction projects on existing trees.

In addition, arborists will provide services such as mulching and spraying. They will use a wide range of equipment such as trucks, tractors, chippers and power saws. They will often be required to climb with ropes and harnesses, or drive a truck-mounted lift to work on large trees. They will need to be aware of local laws and regulations, and adhere to industry accepted practices.

Arborists can be found across the United States, with more opportunities in warmer climates with longer growing seasons. They are usually employed by tree service companies, or are self-employed. Some arborists may choose to specialize in a particular field, such as pruning or landscape work. Arborists can be found working on residential, commercial and public property, as well as in parks and forests.

If you’re looking to hire an arborist for your business, be clear about what the job entails and how much it pays. This helps prevent applicants from getting to the final interview only to find out that the position is outside of their budget. It is also a good idea to state whether the role is full-time or part-time, seasonal or year-round.

The ISA offers an accreditation program for arborists, who must have at least three years of work experience and pass a written exam to achieve certification. The ISA also offers an online continuing education course to keep arborists up-to-date with the latest trends and developments in the industry.

Unlike the “tree guy down the street,” who treats tree removal as the first course of action for damaged trees, an arborist will always try to save the tree if possible. This is because a qualified, insured arborist will have the skills, knowledge and equipment to do so safely.

People who are best suited to being an arborist tend to be independent individuals, stable and persistent, genuine and practical. They enjoy tasks that are tactile, physical and athletic, and they often have an enterprising personality.
