There is an increasing public concern on urban trees arising from improper pruning, interference and felling of some of them. Failures of sizable trees resulting in damages to properties and human lives were even more of a concern. Proper tree management and maintenance by well trained and qualified personnel are of vital importance in enabling the public to enjoy the benefits of urban greening.

Arboriculture is an emerging industry in Hong Kong. It is developing fast as a result from the input from a number of dedicated practitioners. However, up to date, arboricultural practitioners in Hong Kong are not yet represented and regulated by any local organizations recognized by statutory instruments, nor are there any locally enforceable constitution, regulations, or Code of Conduct that bind their conduct and standard of service. From time to time, HKILA have received feedback from our members and the public that the standard of arboricultural services varied substantially, some being far from satisfactory.

For the good of the construction industry, and the general public, the HKILA recognized the need to set up a local accreditation system for the arboricultural industry. Such accreditation system will register a list of arboricultural practitioners that are assessed to have met stipulated minimum academic, professional and experience requirements. The list shall be made available to the public for their reference in procuring arboricultural services. We recognize a person on the accredited list should possess sufficient knowledge and experience to deliver reasonable arboricultural services.

The Development of the HKILA AAP Scheme

The Practice Committee and Public Affairs Committee of the HKILA jointly formed an Arboricultural Practitioners Accreditation Work Group in October 2010. This work group formulated and developed framework of the accreditation system, which was then endorsed by the Council of HKILA in July 2011. The HKILA Accredited Arboricultural Practitioners Vetting Panel (the AAP Panel) was subsequently formed in November 2011 to administer and implement the accreditation process. Through the initial membership referral scheme (referred as the first batch), the first batch of HKILA AAP was accredited and published on our website in July 2012.

Arboricultural Practitioners accredited by the AAP Panel are entitled to describe themselves as 'HKILA Accredited Arboricultural Practitioner' and to use the abbreviated designation 'HKILA ArbP'. HKILA ArbP will be bound by the Code of Ethics and Conduct for Arboricultural Practitioners under HKILA AAP scheme and are eligible to become an Affiliate Member of the institute. Joining as a HKILA Affiliate Member is not mandatory and would have no effect on the renewal of accreditation status. There will be Continuous Professional Development requirements for the yearly renewal of accreditation to be announced at a later stage.

Application Open to Practitioners in Arboriculture Industry

We have received positive feedback and general support from practitioners in the local arboricultural industry. We are aware that there is a growing voice to urge for expanding the number of AAP in order to cope with the increasing demand for qualified arboricultural personnel of supervision level in the construction industry. We are now inviting applications for the HKILA AAP which are opened to all practitioners in this field.

For decades, members of the HKILA have been taking up the roles in landscape planning, detailed design, supervision of greening and landscaping works. We are pleased to assist in promoting regulatory control on arboricultural works, ensuring proper tree management and supervision of landscape works being implemented in Hong Kong.

Code of Ethics and Conduct for Arboricultural Practitioners



Formation of Inquiry Committee

Two arboricultural practitioners accredited under the HKILA’s AAP scheme, Sum Yu Hin (accreditation no. AAP018) and Mr. Lau Siu Yeung (accreditation no. AAP008) were charged by the Independent Commission Against Corruption (ICAC) with bribery of conspiracy for accepting illegal commissions.

Details of the case per press release from ICAC: http://www.icac.org.hk/en/pr/index_uid_1839.html

Mr. Sum was pleaded guilty in the Eastern Magistracy on 7th July 2016, while Mr. Lau had his case adjourned to 28th July 2016.

This case has been brought to the attention of the HKILA Arboricultural Practitioner’s Accreditation Vetting Panel (the Panel or this Panel).

The subject of the offence is considered by this panel directly related to the duty of their works as arboricultural practitioners and in breach of the Code of Ethics and Conduct for Arboricultural Practitioners under HKILA Accredited List, in particular paragraph 3 and 6 under “code of conduct. This panel decided to suspend with immediate effect the accreditation status of Mr. Sum and Mr. Lau. An inquiry committee nominated by the Panel and appointed by HKILA Council is formulated to carry out an inquiry in the case, with the following personnel:

Mr. S C LO (vice-president of HKILA, member of HKILA AAP Vetting Panel) Mr. Paul CHOW (council member of HKILA, member of HKILA AAP Vetting Panel) Mr. Ken SO (external advisor of HKILA AAP Vetting Panel)

The inquiry committee is entrusted by HKILA to conduct proceedings and investigation, and provide recommendation to this Panel and HKILA council on the resolution. We shall announce the updates in due course.
