Arborists are tree care professionals who are highly trained in the science of arboriculture, which includes the identification, cultivation, management, and protection of trees. They have an in-depth understanding of the biological needs of trees and are skilled in the processes of planting, pruning, trimming, and removing them. Arborists are also experienced in the diagnosis and treatment of plant diseases, insect infestations, and hazardous conditions.
Arborists can be found working all across the United States, with more opportunities in warmer climates. They spend most of their time outdoors in all kinds of weather and often need to work at great heights using a variety of tools. Arborists are also exposed to contaminants like pesticides and fertilizers on a regular basis and need to wear protective gear to protect against these risks.
Some arborists work on urban forestry, in parks and other public spaces. They use their expertise to help maintain the safety, beauty, and health of these areas. In these roles, arborists can also be found advising community members and businesses on tree issues, planting, and care.
Other arborists choose to focus on specific aspects of tree care, such as pruning ornamental species or shaping shrubbery. In these roles, they use their training to improve the visual appeal of landscapes by removing dead or unhealthy branches and by reducing the weight of the crown. They can also perform “crown raising” to allow pedestrians to walk under a tree, and they can cut away limbs that pose a risk to power lines or buildings.
During their training, arborists learn to understand the structure of various types of trees and how to assess their health and safety. They can then identify the best ways to care for each kind of tree, including how to trim and remove branches, plants, and roots in order to keep them healthy. They may also be able to diagnose and treat plant diseases and insect infestations, which they can prevent or control through environmental changes, pruning, and direct injections.
Before hiring an arborist, it’s important to check whether they have ISA certification. The ISA, or International Society of Arboriculture, is an industry organization that offers credentials to those who meet their educational and professional requirements. Those who want to be certified arborists must complete a series of courses and hands-on projects, and then pass an exam.
The ISA offers a list of recommended study resources, and there are many other online resources that can help prepare for the certification exam. In addition, it’s wise to find out whether an arborist has a valid workers’ compensation and personal liability insurance policy before granting them access to your property. It’s also worth checking if they have the right equipment, such as a load bearing karabiners conforming to EN362 that can be used for rigging and climbing in trees. This will ensure they can safely and effectively carry out their duties. It’s also a good idea to get references and visit previous job sites before hiring an arborist.
