Arborists work to protect trees from insect infestations, sun bleaching, and fungal infections. They can also remove damaging plants and provide drought mitigation. They can also improve the appearance of decorative species. They can also recommend trees for specific conditions, such as climate zones. They can help plan preventive care for trees in advance of spring.
They may work for an insurance company, a tree nursery, or in a state park service. They may also work in private lands or in an urban environment. Some of their jobs require specialized vehicles or equipment. Depending on the company, an arborist may perform soil analysis, hazard assessments, moisture testing, or disease detection.
Aside from the usual tasks, an arborist may be required to take an exam to become certified. Certification can be obtained through a university or vocational program. After obtaining this certification, an arborist must continue to hone their craft and learn new techniques. The International Society of Arboriculture (ISA) offers six different certifications. To maintain this certification, a certified arborist must retake an exam periodically.
To become an arborist, you need to have a high school diploma or GED. You can then choose to specialize in a particular type of tree. Many arborists work as climbers for 5 to 10 years before branching out on their own. They can become supervisors or crew leaders.
Those interested in advancing in the field can consider completing a bachelor's degree. Having a bachelor's degree will increase the likelihood of getting a job in the tree care industry. The most common entry-level positions require only a high school diploma. However, some employers will require an associate's degree in horticulture or arboriculture.
An arborist must have a thorough understanding of local tree species. They will also need to understand safety rules regarding working around power lines and wildlife. They will need to learn first aid and how to deal with poisonous plants. They will also need to be knowledgeable about the proper use of pesticides. They will need to know how to work with a chainsaw and other tools.
