ISA HK/China --- HK Tree News (Tree Failure in Stanley causing Fatality)

*** Our weekly Station Mail is for the information of Station Members only, but Station Mail has given up copyright & can be freely circulated. For administrative reasons, comments from outsiders are usually not entertained & may be circulated within our system locally & overseas. Please note Station Mail is sometimes given in Blog at , although images are usually not attached due to size. ***

Dear Station Members,

This Station has received enough messages & phone calls to demand a Station Mail on the hot topic of the killing Erythrina in Stanley on 27.8.08 from Station Members & media. Please kindly note ISA HK/China is a research & education organization only. We do not take side for anybody, & the information given in this Station Mail will take the attitude of an Independent Practicing Arborist (IPA) to be impartial, fact-finding & truth-telling under the details gathered by this Station.

Before anything else, ISA HK/China would like to mourn the victim of the event with grief, who was a 19 year old fair lady having a bright future ahead of her. We wish to offer our deepest condolence to her family & pray for her soul to rest in peace in heaven.

It must also be stated that the Station Manager issuing this Station Mail has not been on site, & has never seen or touched this fallen tree before the failure. Therefore, anything written down here would come from media reports only & shall be deemed as invalid for any legal or professional investigation.

From information gathered so far, it appeared that this tree failed on a calm sunny afternoon without warning to hit the passing crowd underneath causing fatality. This tree was claimed to have been inspected by a Govt Dept only a few days before the failure. It was also said to have undergone Tomograph for decay, & was quoted with result as 'acceptable'.

The remaining parts of the fallen tree were quickly removed for any post-mortem investigation. Without such, it would be hard to study the failed portion & to determine whether the branch was failing out of heavy end-weight, or from an internal decay with crack development eventually leading to breakage. Post-mortem is vital to assess the cause of the failure & without such, much of the comments here would become guesswork & IPA must not guess but state from facts.

Wind damage might not be a direct cause for the branch breakage as the weather during the failure was sunny & calm. Tree Experts suspected Erythrina Gall Wasps had weakened the tree but again, shell thickness would need to be determined against end weight & tree structure. Decay development, internal cracks, canker damage & branch structure would all need to be assessed for a probable explanation. Any of the above would require measurement of the tree before failure & after failure. It would be like forensic experts examining a murder case. Playing Tree Detective is part of IPA work.

Therefore, in view of the lack of measurements & technical details before & after the failure, for any responsible IPA, no conclusion regarding the cause of the failure can be easily drawn except this tree had failed in an unexpected circumstance. This Station is very sure that no Govt Dept in any civilized world would like to see a tree to fail to kill a civilian. Whether the incident involved Negligence or not, it would be up to the Court to decide.

While we mourn the deceased with pain, we may at the same time need to look for the future to avoid similar incident. Our Tree Professionals may wish to remind our authorities to divert extra resources to pick out those Mature Trees which have turned into Time Bombs already in our city. IPA may be deployed to provide third party opinion to explain to the public. More work will need to be done.

ISA HK/China does not look forward to issue Station Mail of this kind with grief, & sincerely wish our trees can be our assets instead of liabilities in our loving city.

best regards,

Sammy Au
Station Manager
