Dear Station Members,

For those of you who can search newspaper online, please kindly look up South China Morning Post Saturday May 7, 2011 at 'City' section, for a piece of local news on "Top girls' school hit with heavy fine for tree pruning".

According to the newspaper report, the fine is HK$200,000.00 for incorrectly pruning a Candlenut tree (Aleurites moluccana), something that some agreed as just, & some disagreed. The incident came from a tip-off by a local group after they saw the pruning, to the Govt authorities for action. A local Arborist commented on the work, so did other Tree Experts. There appears to be no common approval on the quality of the work, although no international standards have been brought up against it, but only personal opinions.

From the photos acquired, the work looks more like Topping than Structural Pruning. Stubs were left & tree parts were cut in random. Apparently no justifiable pruning design had been conducted before the work, & it was said that the leading worker on the pruning gang was once a Certified Tree Worker working for the Govt. We wonder who he is? All Certified Tree Workers in HK were evaluated by the Station Manager who has been the Chief Proctor since Nov 2006. Would it be someone before that period? This case may go to the Ethics Committee of ISA to revoke his certificate as a maximum penalty, if proven & justified.

This girls' college is the second in line for heavy pruning fines after the previous hospital in Aug 2010. This is suggesting that the HK Govt is paying attention to unacceptable treatment to damage trees. It may be a reality in HK that trees become more damaged after 'pruning' than before. Look up those trees in natural forest without artificial pruning. Do they fail more than the city trees given with frequent pruning? HK needs to learn more on proper pruning, & this cannot be done without getting the Arborist up on a tree with ropes & chainsaws. Anyone designing or supervising Tree Pruning without having doing it himself for some time to understand the biomechanics & reaction of trees after pruning, would be like employing a doctor who has never operated in surgical theatre before for removing body parts. Can he really manage the complicated work?

HK has many 'Office Arborists' but lacking Practicing Arborist. ISA HK/China is fully aware of this in our drive towards China. Or else, our brothers & sisters would simply find somebody better to replace us.

若各位能够在网上溜览报章的话,请翻查2011年5月7日星期六的南华早报’ 城市’ 版,一则本地新闻关于” 修剪树木,著名女子学校受重罚” 。


从图片得知,修剪工作像斩顶而多于结构修剪。残枝仍然留在树上而树的各部份也是随意修剪。明显地,在工程之初,没有进行过适度的修剪设计;及有人说,修剪队伍的领导曾是为政府工作的注册攀树师。我们猜度究竟他是谁?所有在香港的注册攀树师也会由会长 --- 从2006年11月至今的主考官 --- 评核过。也许是在之前的某人?这事件可能会上达至ISA的道德委员会,若证明失德有理,最高的惩罚是撤销他的证书。


香港拥有很多 “办公室树艺师" 但缺乏能够在现场操作的 “执业树艺师”。ISA中国地区分会在我们进军中国之时已充分警觉此事。事态若是如此发展,国内的兄弟姊妹可能会简单的找一些更能在现场操作的工人去取代我们的“办公室树艺师"来修树, 这是否我们愿意见到的呢?
