Why do I need a Certified Arborist?

Below is a description of what a Certified Arborist is, what levels of excellence they are held to and who the governing authority is. Excel Tree Experts believes that as tree care service provides, the ISA Certified Arborists designation is essential for both our company and our clients. The following information published by the ISA (Interntional Society of Arboriculture):

Why do I need a Certified Arborist?

Certified Arborists are tree care specialists dedicated to excellence in the field of Arboriculture.  They are highly qualified in the care of your valuable trees and shrubs with knowledge of the most up-to-date advances, and proven age-old techniques.

Certified Arborists are widely recognized professionals.  They are educated and trained in:

  • Diagnosis and treatment of your tree and shrub related to problems.
  • Proper pruning and management techniques for your valuable trees and shrubs.
  • Understanding tree biology.
  • Identifying and selecting the appropriate trees and shrubs for your landscape.
  • Installation and establishment of trees and shrubs to enhance your landscape.
  • Understanding the delicate soil and water relationships which affect tree and shrub health.
  • Nutrition requirements and fertilization techniques to keep your trees and shrubs in peak form.
  • Recognizing certain tree hazards and construction damage.

To maintain and beautify the world around us, residential property, commercial property, or the town you live in, Certified Arborists are there to help you.

To qualify as a Certified Arborist, an experienced tree care professional must pass an extensive examination developed by an international panel of experts in the industry and academia.  The International Society of Arboriculture maintains this voluntary certification program.

The educational program does not stop with testing.  A Certified Arborist must keep arrest of new technology, by attending seminars and reviewing the latest publications to obtain necessary continuing education credits.

In today’s fragile environment, a Certified Arborist can maintain your landscape and help you preserve the aesthetic and ecological value of your trees and shrubs.

Please remember, Certification can attest to the knowledge background of an arborist, but it does not guarantee or assure quality performance.  It is a means to assist you in selecting an arborist who has a proven level of knowledge based competency.

Not all arboricultural firms have Certified Arborists on their staff.  When choosing a tree care firm, check the classified pages for those companies that employ arborists who are certified.  Do not hesitate to ask any prospective arborist to see their International Society of Arboriculture (ISA) Certification Identification Card.

For additional information, contact your local Cooperative Extension Office, State urban Forestry Department, ISA Chapter; or the ISA Certification Office at (2170355-9411.
