What is the International Society of Arboriculture (ISA)?
A: The International Society of Arboriculture (ISA) was founded in 1924 and has served the tree care
industry for over seventy years as a scientific and educational non-profit organization. ISA supports tree
care around the world and is dedicated to the care and preservation of shade and ornamental trees.
This organization continues to be a dynamic medium through which arborists around the world share
their experiences and knowledge for the benefit of society. Aligned on many fronts with other green
organizations, ISA is working hard to foster a better understanding of trees and tree care through
research and the education of professionals as well as global efforts to inform tree care consumers.

What is the difference between an arborist and a certified arborist?
A: Arborists are trained professionals that are knowledgeable and equipped to provide proper tree
care. They are specially trained to provide a variety to services to maintain trees. ISA Certified Arborists
are individuals who have achieved a level of knowledge in the art and science of tree care through at
least three years of experience and have passed a comprehensive examination. They are also
required to continue their education in order to maintain their certification, ensuring their knowledge is
updated on the latest arboriculture techniques. ISA Arborist Certification is a non-governmental
voluntary process that operates without mandate of law. It is an internal self-regulating device
administered by the International Society of Arboriculture, and therefore, cannot guarantee or assure
the quality of performance. Certification provides a measurable assessment of an individual’s
knowledge and competence required to provide proper tree care.

Why should I hire an arborist?
A: Trees restore natural harmony in an urban environment, giving scale to human life. Trees are alive,
like us, and require an investment and continuous maintenance in order to provide the maximum
desired benefits. Some benefits include:

* Air Filtration? filters out particulate matter and absorbing harmful gases
* Purifies Water? slows and filters rain water and protects aquifers & watersheds
* Cost Reduction? reduces yearly heating and cooling costs by 2.1 billion dollars
* Climate Control? obtained by moderating the effects of sun, wind, and rain
* Increase Property Value? well-cared landscape properties are 5-20% more valuable than non-
landscaped estates.

For a healthy and long life, trees need the proper maintenance. Therefore, in order to provide proper
tree care, you should refer to a certified arborist.

How often does my tree need care?
A: The type and frequency of tree care depends on the species, age, location, climate, and other factors
that affect the tree’s growth. The first step is to educate yourself about your trees and understand their
needs. It is imperative to understand that proper tree care is a life long process, and that planting and
caring for a tree is a long-term commitment, not just a one time deal.
