What is an Arborist and its Daily Responsibilities?

Take an arborist as a doctor of plants. And this is why they are also commonly called “tree surgeons.” In other words, they take care of all types of plants, such as – shrubs, vines, and trees. 

But how? By ensuring that they stay away from insects or diseases and are in their best shape to live a healthy life. As an arborist, your daily responsibilities may include:

  • Removing dead, diseased, or hazardous branches to improve tree health, structure, and appearance.
  • Cutting down and removing trees that are dead, hazardous, or in the way of new construction.
  • Selecting, planting, and transplanting trees to improve the landscape.
  • Identifying and treating diseases and pests that can harm trees.
  • Evaluating the health, stability, and structure of trees to determine the best course of action for maintenance or removal.
  • Installing cables and braces to support weak branches and improve the stability of the tree.
  • Respond to emergency situations, such as fallen trees or broken branches, caused by storms or natural disasters.

Now that you know what an arborist is, let’s have a deeper look at the certification authority.

  • Have at least three years of full-time job experience.
    OR 
  • Have a combination of education and practical experience equalling 3 years.

    Note: One year of full-time experience as an arborist is equal to 1795 work hours.

But how should you prepare for the exam?

So, are you ready? Ok then, pass the exam to get your credential. The exam consists of 200 MCQs (with 4 options) and provides you with a time of 210 minutes to attend them. 

You need to get a score of at least 76% to clear the exam. If you fail to do so, you will need to retake it.

Congratulations. Now you are an ISA Certified Arborist.
