The arborist is an important professional who ensures that trees and other plants remain healthy and safe for our environment. These are workers with professional education and obligatory practical experience in tree treatment, so they recognise tree biology, insect diseases, and correct pruning methods. Yet not all arborists are the same, there is a distinction between their qualifications and, thus, the service provided. An “Arborist Qualification Checklist” is a useful guide of a list that is important to both the aspiring arborist and one who wants to hire a professional. These areas of certification, skills, and experience are important when deciding whether or not an arborist is ready to safely and effectively take on many different tree care services. It is important to know the qualifications mentioned above when making decisions regarding the trees and thus have a healthy and safe environment.
