Dear Station Members,

After the Stanley Tree Failure in 2008 in HK, the city has gone on a frenzy to conduct Tree Risk Assessment (TRA) apparently to respond the political pressure. 95+% of the HK Arborists in the private sector right now would focus on TRA alone, because this is the biggest share of the pie. Courses of variable quality have sprung up everywhere on TRA. Laymen want to be Certified Arborists instantly because of the sudden market in TRA. The Arboricultural Discipline appears to be all about TRA alone in the small city of HK.

ISA HK/China, managing ISA activities for hundreds of cities in our territory of HK, Macau, Taiwan & China, does not see practicing TRA as the only domain in HK as healthy. This is like keep on pushing vitamin pills alone & ignore general food. The Arboricultural Discipline contains many more subjects other than just TRA. This is represented in the highest credential of Board Certified Master Arborist (BCMA) of ISA, where in all 19 Domains of Arboriculture are required to be tested. They include:

1. Abiotic Influence

2. Tree Biology

3. Biotic Influence

4. Diagnostic Process

5. Plant Identification & Selection

6. Soil Science

7. Climbing, Rigging & Removal

8. Installation Practice

9. Integrated Pest Management

10. Irrigation

11. Pruning

12. Soil Treatment

13. Support & Protection

14. Business Relation

15. Inventory & management Plans

16. Plant Appraisal

17. Tree Risk Assessment (TRA)

18. Safety at Work

19. Tree Preservation

It can be seen that TRA is just one Domain among the rest. An Arborist is supposed to master all-round knowledge & not biased on one single subject alone, because the knowledge of the other subjects will help him to make better observation & decision on that single subject. This appears to be a common fact in any scientific discipline.

In the above, a Certified Arborist is tested in multiple-choice around a combination of 10 Domains in basics. Only around 10% of the questions are on TRA. The Registered Consulting Arborist ( http://isahkchina.blogspot.com/2010/12/isa-hkchina-first-rca-in-asia.html ) credential requires the candidate to further deliver all the above knowledge in oratory & writing to international skills. Arboriculture is much broader than just filling in forms for TRA.

ISA HK/China has over the years recommended our Arborists to master profound knowledge in Tree Biology & Wind Mechanics, before attempting to conduct something so sophisticated like the TRA. If not, it is always true that Mother Natures makes the Rules. We also need to find why our trees have turned into risks in the first place, & stop them. Otherwise, we shall keep on producing risky trees.

HK is just one city out of hundreds in our territory, & HK cannot influence how ISA is developed here. In our Exchange Visit to China next week, ISA HK/China will deliver a complete package of knowledge in Tree Standards, Installation & Pruning, Tree Climbing & TRA to our brothers & sisters, who do not know much about Arboriculture nor ISA. Arboricultural knowledge links to one another & one subject alone cannot be taken out to represent all. ISA HK/China keeps an open mind & clear vision on how to develop proper Arboriculture in our territory under ISA Mission. Nothing can deviate us from that.

May the HK Arborists spread out to develop other skills of Arboriculture to meet the world. If not, HK Arborists will soon be marginalized, when they come to meet others on knowledge whether locally or overseas.

Just think about those coming to ISA Sydney Conference with us to meet the world ...

best regards,

Sammy Au

各位会员,

自2008年香港赤柱塌树后,香港似乎是由於政治压力而对树木风险评估(TRA)产生了一股狂热。有九成多的香港树艺师会只专注於 TRA上,因为这是整个馅饼中之最大份量。质数参差的TRA课程如雨後春笋般崛起。 外行人以TRA为生意, 都想成为 “注册树艺师”。在香港这个小城市, 树艺学似乎全是只关注单一的TRA而矣。

本分会是管理在香港, 澳门,台湾及中国境内数百个城市的ISA机构,对香港树艺师只从事TRA认为毫不健康。树艺行业不只是操作TRA而矣, 而是非常广阔。在ISA 的最高级文凭 “资深树艺师”(BCMA)内,所有19个树艺领域都要经过测试。它们是:

1. 非生物界的影响

2. 树木生物学

3. 生物界的影响

4. 诊断过程

5. 植物识别与选择

6. 土壤学

7. 攀树,索具及移除

8. 安装和实践

9. 病虫害综合管理

10. 灌溉

11. 修剪

12. 土壤处理

13. 支撑和保护

14. 业务关系

15. 统计和管理计划

16. 植物鉴定

17. 树木风险评估(TRA)

18. 施工安全

19. 树木保育

从这19个领域中, “注册树芸师” 只是被测试其中10个领域,及局限於基本常识。至于 “顾问树艺师”( http://isahkchina.blogspot.com/2010/12/isa-hkchina-first-rca-in-asia.html)  之认证, 考生更是被要求以口述及写作能力来传达上述知识至国际满意的程度。

由此可见,在ISA众多领域中, TRA仅仅是其中一个。本分会多年来都建议任何树芸师, 都要掌握好对树生物学及风力学之渊博常识後,才可尝试处理类似TRA之复杂事项。不然, “由大自然决定成败 ” 经常是对的。

香港仅仅是我们领域里数百个城市当中的一个 ,而且,香港不能影响本分会如何去发展ISA树艺。 例如,在我们下一个进入中国之交流参观会内,我们将传递一套 “树本标准,安装及修枝,攀树与TRA” 的完整基本知识。这些知识互相连结,而且不能剔除当中任何一项去宣称这就是这样了。本分会在ISA使命下对如何在我们领域上发展适当树艺, 保持着开放的态度及清晰的视野, 没有什么能令我们由此偏离。

但愿香港的树艺师们, 能伸展出去发展其他树艺技能去衔接世界。否则,当香港树艺师与海外树艺师相比之时, 将会被再次边缘化。

试想想,那些与我们前往ISA悉尼会议的同伴们会如何面对世界 ...

此致

ISA HK/China --- Writing Arborist Report 撰写树艺报告

国内朋友请使用翻译软件阅读本文 (http://translate.google.com.hk/?hl=en&tab=wT#enzh-CN)。

Dear Station Members,

ISA HK/China frequently receives complaints upon our local Arborist Reports in HK from various clients. Issues include poor English, irrelevant information, inaccurate description & lack of clear decision. Clients complain that they have difficulties in making judgment after reading such a report, & would regard it as unprofessional as compared to other disciplines.

It is true that the Certified Arborist (CA) exam does not test for English report-writing. This appears to belong to the following reasons:

1. The CA exam was originally developed in North America & candidates there would use English as their mother tongue. Somehow if a report is required, the CA there can write something out that is understandable in their own language.

2. Arborists in western countries would do all kind of Arborist work from design, selection, maintenance, inspection, protection to risk assessment. Writing up detailed technical report like those frequently demanded by Govt Depts in HK, would belong to specialists like the Consulting Arborists (www.asca-consultants.org), who are trained to address such issue with good communication & technical skills.

In our territory, Arborist work is lob-sided to Tree Risk Assessment (TRA) due to political influence. Whereas quantitative TRA is done by filling in forms for quick assessment, there are times where Govt Dept would require special focus on trees pending detailed investigation. There are also cases where trees have been damaged or interfered under public attention. The client would then like to obtain specific information on the extent of damage/interference, & make a decision on the next move. For this kind of work, a common Tree Survey or Ecological Assessment report will fall short of what the client is looking for, & would not help them to make a justified decision.

Whereas the CA exam came to our territory, it made the same assumption that all our candidates can use English in their daily life. This is certainly too much to ask for, as a lot of our local candidates may read English well, but not to speak or write it the same, since Cantonese is the mother tongue in HK. Also after 1997, many politicians have encouraged using Cantonese as the common language even in Legco. English more or less remains for business/administration writing, & there is a trend that it is getting stereotypic as seen in many of the daily communication issued everywhere.

ISA HK/China has not seen by now a good Arborist Report with many pages of description written to international standard in HK. Most of the time, the report structure is confusing; the language used is full of errors; the observation is unclear without justification; & the conclusion is unconvincing. All there is appears to be nice packaging of pages after pages of irrelevant information, which can drown the reader into boredom & confusion. Such a report can be easily challenged at Court.

It is also noticed in a lot of the Arborist Reports which mention that they are written to the "Practicing Standards" of ISA. ISA is a research & education organization. It does not produce "Practicing Standards". Any CA who puts this in may have impeached the Code of Ethics of Certified Arborist, & may be subject to investigation by ISA Cert Dept.

Many people have been respecting our newly emerged Arborist Profession partly out of respect for the prestigious organization of ISA. If our local Arborists do not upgrade themselves in their performance, the respect may not last forever. ISA HK/China will collaborate with Govt Depts & public to eliminate poor quality work, & will not fight to be there by status. ISA HK/China will insist on quality work. After all, HK is just one city out of hundreds in our territory of HK, Macau, Taiwan & China. Why should we protect the HK Arborists alone for bad work?

ISA HK/China has set up a Qualified Arborist credential (QA, http://isahkchina.blogspot.com/2010/09/isa-hkchina-qualified-arborist-qa.html)  to elevate our performance locally. One of the focus is report-writing in its requirement. The QA credential is also modeled after the Registered Consulting Arborist (RCA, http://www.asca-consultants.org/)  requirements, although in a much junior level. At least Technical Writing is not demanded in the QA. ISA HK/China regards our QA can write a basic Arborist Report of some sense. Clients should demand QA to give them readable Arborist Reports in future.

ISA HK/China will try to deliver 3 session of ISA Tree Seminars to introduce "Technical Writing" to our Station Members later on. A mere 3 session will not instantly qualify an Arborist to write international report. However, it will help.

ISA HK/China will relentlessly upgrade our Arborist Profession locally, one tree & one Arborist at a time.

各位会员,

本分会经常接到不同人仕对本地树艺师所撰写的英语报告的投诉,包括英文差,加入不相关的資訊,不准确的描述以及缺乏明确的决定。客人抱怨说他们在阅读这样的报告后并不能作出适当的决定,从而觉得本地树艺师并不够专业。

事实上,"注册树艺师" 考试并不测试撰写英语报告, 主要基于下列原因:

1.此考试最初是在北美洲发展起来的,当地考生是以英语作为母语。如果他们要用英语撰写报告,这些树艺师是不难做到的。

2. 树艺师在西方国家是负责全面的树艺工作,包括设计、选种、维护、检查、保护及风险评估。 香港政府部门也经常要求写作详细的技术报告,这些工作应该由一些专科人员, 例如 “顾问树艺师”(www.asca-consultants.org)去担当, 而并非由一般 “注册树艺师”去担任,因为 “顾问树艺师”们接受过另类培训,拥有特殊的沟通能力及和技能。

由于政治影响,香港树艺师的工作侧重于树木 “风险评估”。 大部份的评估是通过填写某些简单表格快速做出的。 然而有些时候,政府部门是需要更加详尽的树木报告。还有一些情况下,树木的损坏及干扰是受到公众关注。客人有时候也需要取得具体的资料,去了解树木是受到何等程度的破坏或干扰,才能决定下一步的行动。在这样的大前提下,一个普通的 “树木统查’ 或 “生态评估”报告并不能够提供足够的资料帮助客人来做出合理的决定。

当 “注册树艺师”考试来到香港的时候,它假设了所有考生是在日常生活环境中使用英语的。但这显然是不恰当的假设,虽然大部份本地考生可以阅读英语,但他們说讲和书写英语的能力并不高,因为自从一九九七年开始,粤语已变成为香港的母语。一九九七年后,许多政治家都鼓励使用粤语为共通语言,即使在立法会会议亦是如此。尽管在商业/管理写作上仍然仃留使用英语,但在日常沟通上, 英语的使用已经渐趋公式化, 而树艺报告倒是千变万化。

本分会直到现在还没有看过一个达到国际水平的本地树艺报告。大部分时间,报告的结构是混乱的,所用的语言充满了错误,观察往往是不明确, 或是理由不充份,结论亦往往也是不能令人信服。包装报告往往在不错的页面设计及不相关的资讯下,令读者感到混淆及困惑。这样的报告是很容易地在法院被提出质疑的。

我们亦注意到在很多的树艺师报告中提及报告是符合ISA的“执行标准”。 然而,ISA是一个研究和教育机构,它并不制定“执行标准“。任何树艺师把这个不遵守 “注册树艺师”道德标准的字句加入报告内,可能会受到的ISA发牌部门的调查

许多人都尊重我们这新出现的树艺师专业, 部分是出于尊重我们这个国际权威组织ISA。但是,如果本地树艺师不保障自己的专业表现,这种尊重不可能永远持续下去。本分会将与政府部门及公众合作,消除质量差的树艺工作,以及不断地向前进步。本分会将坚持贡献高质量的树艺工作及把持专业态度。毕竟,香港只是在中华地区数百个城市的其中一个。我们为什么要特別关照香港能力低下的树艺师, 而损害整体利益?

本分会已成立了一个 “认可树艺师” 的认证制度 (QA , http://isahkchina.blogspot.com/2010/09/isa-hkchina-qualified-arborist-qa.html ) ,以提升我们的本地水平。要成为 QA, 其中一个重点是报告的撰写。 “认可树艺师” 的认证是仿照 “顾问树艺师”(RCA, www.asca- consultants.org) 的要求,但仃留在较初级的水平, 亦不要求懂得“技术写作”。本分会认为我们的 “认可格树艺师” 是可以撰写有一定意义的基本树艺报告。客人亦可在未来要求聘用 “认可树艺师” 去提供可读的树艺师报告。

本分会在不久将来会提供三节讲座,向本会会员介绍 “技术写作”。短短三次讲座将不会立即令本地树艺师写出国际水平的报告。但是,它会有所帮助。

本分会将坚持不懈及一步一步地提升本地树艺师的专业水平。
