The ISA Hong Kong Chapter was formed at the beginning of 2012 under the auspices of, and technical guidance provided by the International Society of Arboriculture. (ISA)

The ISA had been a growing presence in Hong Kong since it first began offering the ISA Certification Exam as far back as 2004. Several years later ISA Members living in the HKSAR decided to develop a local chapter to assist with the growing need to provide networking, education, and training opportunities for those who live and practice in Hong Kong. Today, there are more than 1,000 ISA Certified Arborists in Hong Kong of which 250-plus are current ISAHK Chapter members.

Our Mission

Through research, technology, maintenance of standards and education our mission is to promote the professional practice of arboriculture and foster a greater public awareness of the social health and environmental benefits of trees throughout the Hong Kong community.


Our Education Committee will help organize seminar/training to suit the needs of credential holders to accumulate their continuing education units (CEUs). 

Help organize examination

Our Certification Committee will help to organize the CTW skill exam, QCPT exam and certification. 


The ISA Hong Kong Chapter offers membership benefit to members, where they can obtain the latest industry updates and information through the media of conferences, seminars, workshops and events. They can also establish and maintain a network of professional arborist connections in Hong Kong.

Our Membership Committee will also organize bulk book purchases from overseas for both members and non-members with different discounts being applied.  

Tree Climbing Activities and Competitions

Our Tree Climbing Committee organizes and holds tree climbing activities and competitions for the general public and for industry practitioners. Our aim is for such activities and competition to promote and enhance the development of tree climbing sports in Hong Kong particularly among young people. These competitions also demonstrate to the public how professional tree works should be performed as part of the daily routines.
