会员们:

本分会长在 2012中国园林领袖会议里, 展出过两场的 "树木修剪示范", 受到了一致好评, 详情可见附页。

修剪是树艺学当中一门非常重要的课题, 是所有 "执业树艺师" 必须掌握的知识。 对很多大树老树而言, 修剪往往是唯一可行的护养技术和减免风险的方法, 所以正当修剪对树木管理尤为重要。 修剪的理论看上去好像很简单, 但在现场操作起来, 许多未能预见的问题经常都会出现。 比方说, 切下去才看到枝条里面有腐烂、层裂或其他毛病, 哪还该再切多少, 才不会影响树体的结构和健康, 这动作会改变日后树体对周边的公众安全吗? 多过及年, 树体又将会变成怎样样的发展?

树木修剪其实就好像人体手术一样, 必须先经过专业检查和监定以后, 厘定修剪方案, 再由合资格的树艺师监督进行, 进行的人又以采用攀树师最为理想。 树木修剪涉及树艺学里面的生物学、结构学、病虫学和法律责任, 乱剪的树木日后会变成乱长, 最终更可能变成 "不定时炸弹", 为害社会。 在中国地区, 目前去讲 "树木修剪理论" 的人很多, 但当中又有多少个敢爬到树上, 使用电油锯把枝条运用溜缆技术安全的切下来? 又有多少个能指揮攀树师在树上的工作? 如果自己只会光讲而不会做, 这又能有说服力吗?

树木从生产、种植、护养到检查,都要涉及修剪。 换句话说, 不懂得正当修剪的话, 到头来也就得不到优质树木种植。 哪所谓 "优质树木种植", 就是指既安全, 又能提供种种好处的城区树木种植。 坊间说的所谓 "好看" 的树木设计, 也必须要照顾到公众安全, 不然的话再 "好看" 又有啥用? 其实所谓 "好看", 也需要与人家比较。 咱们目前的城区树木能与西方国家的来较量吗? 不能的话, 哪咱们的到底 "好" 在那里, 也为什么不能比较啊?

但愿树艺学和树艺行业能尽快的在中华地区发展起来, 造福社会。

谨此致意!

Dear Station Members,

The Station Manager (SM) gave a Structural Pruning demonstration at the 2012 China Green Leaders Forum & the event was widely publicized on national newspapers in China as per attached. The SM is known as the "Founder of the Arborist Profession" in the China media nowadays. This is an honour & would help to develop the Arborist Profession there against all odds.

If there is anything that the China Tree Care Industry would miss out most, the SM would call it on pruning than anything else. Topping is a common & acceptable practice all over China, & it is taught specifically as a skill of art in many academic institutions. This includes every university in China. The tradition is deep rooted & buried.

When the SM talked about pruning in several "Landscape Bureaus" in China in the past, he was mostly met with suspicion & doubt. The "tree experts" there would insist on what they were taught & what they were practicing, as the one & only method. To them, Target Pruning would be a waste of time, & the tree would not "look good" afterwards. Flush Cut is preferred because it does not leave a bulge at the wound, & it is thought that Topping would generate more sprouting to show the true vigour & "good health" of the tree. The SM kept seeing what he had seen in HK of 10 years ago, & the word would mostly come out from landscape designers & maintenance parties in China.

No doubt China has become the second economy in the world & has achieved many technical advances in the past 30 years. However, there are hardly any mature trees of larger than 1 m diameter left in their 600+ cities. The SM wonders whether bad pruning has something to do with it. He was told by the press that there is at least one person getting killed by tree failure in Beijing alone every year, & the incidence would usually be played down to avoid public attention. Having the SM there to bring up an occasional voice to speak for the trees, would hardly change a thing.

Anyway, somebody has to do the work, or China will take a long time to get good trees. At his age, the SM has no more to lose or fear, & he is an expert China Hand. ISA HK/China will find a way to rally support for proper pruning for the benefits of China trees.

Our mission will continue.

ISA HK/China --- 2012 China Green Leaders Forum 2012 中国园林領袖年会







国内朋友请查閱 "百度博客 --- 国际树木学会" (http://hi.baidu.com/%B9%FA%BC%CA%CA%F7%C4%BE%D1%A7%BB%E1/blog  )   以取得其他文章。本分会的发表文章都已放弃版权, 任何人都可以自由转载作为教育目的, 但不能作为商业目的盈利。 任何人仕都可以申请免費加入本分会, 本分会员名单从不公开, 有意者请将真实姓名、年龄、单位、职衔、最高学历、电邮和手机号传真到 +852-2679-5338 便可. 如有查询, 请电邮至 egc@netvigator.com  。本分会的一切发表内容, 谨供参考。


会员们:

本分会长有幸获邀参加了由中国花卉报和其他国家级单位主办的 "2012年中国园林领袖年会", 并被安排了在讲座发言和现场示范多次, 给参会者留下了深刻的印象。

从9月19日下午5时抵步后, 本分会长晚上7时就开始参加了由全国苗木生产大户出席的苗木发展前瞻研讨会, 分享了他个人对未来国内苗木生产与销售的意见, 供参会者作为参考。 在9月20日上午, 本分会长提供了 "国际通行的行道树生产标准" 的讲座, 现场数百听众反应良好, 而且很多都是第一次与国际树艺知识作出接触, 感觉新奇讶意。

同日的下午2点, 大会在公众地方安排了一场 "树木修剪和大树风险评估" 示范, 刻意的弄来两课生长差异的小树来作表演。 事前并未有看过示范苗木的本分会长手起刀落的示范了 "撕皮切"、"错切" 和 "三刀法" 等的切法, 把原来生成一团的两棵小苗, 分别建立了 "中央主干"、"活冠比"、"螺旋分干" 和 "强接枝" 的扰势树体, 嬴得了全场百多观众的热烈掌声。 接著下来的 "大树风险评估" 表演, 是就地取材的利用马路旁边的行道树作示范对象。 分会长首先让观众们先道出他们所能看得出的树体缺陷, 然后再给每个意见提出了科学论证, 之后再分享了国际方面在此等评估的惯用手法和理论; 如此友善的交流态度和专业精神, 再一次博得了全场掌声。

当在现场示范修剪和评估的同时, 会场内正在举办 "理事单位年会"。 为了让参会理事们没有错过观赏树木修剪的机会, 本分会长当仁不让的再次在众理事专家面前, 把另一课长得乱作一团的树木样本, 使用国际修剪技术把它的树体结构重新建立起来, 令参观者惊叹不已。

在是次参会以后, 本分会长深深感受到 "树艺行业" 这门科学在中国土地上建立起来的重要性和逼切性。 树艺知识可以为国家的绿化事业省很多钱 (优质树木设计种植), 创造庞大就业机会 (市内树木风险评估), 把农闲的劳动力释放出来 (冬季修剪移植), 为读书不成的年青人创造就业机会 (成为攀树师), 好处实在太多了。

本分会愿意倾全分会之力, 去协助所有热心单位去举办第一届的 "全国树艺知识研讨会", 当中只须一天理论讲座, 加一天攀树修剪示范就够了, 只要找到合适的场地、大树和参会者便行。 我方可以派出本地区最好的树艺师和世界级的攀树师来演讲示范, 相信必然引起广大兴趣。

树艺行业对国家、民族和社会都是有益有利, 但愿它能早日在我中华大地里遍地开花吧 !

谨此致意!

Dear Station Members,

It is the pleasure & honour of the Station Manager (SM) to be invited to speak & demonstrate at the 2012 China Green Leaders Forum (CGLF). This Forum is the biggest & most influential in China, & has gathered all recognized personnel from plant production, design, landscape construction to academic research to meet once a year, to discuss the latest development. The attending VIPs are on an invitation basis, & the SM has been given the honour of being the Guest Speaker for the 2 full days while he was there. Please see the attached photos for the various events.

According to the original planning, the SM was there to talk for an hour in the morning session of Sep 20, & then to conduct a site demonstration for tree pruning & tree inspection only. Upon his arrival at 5 pm on Sep 19, the SM was told that the Forum participants would like to see & hear from more of him. Then in total, the SM spoke at the China Nursery Trade Development Seminar in the evening of Sep 19, delivered a Tree Standards seminar at the Forum, conducted a pruning & tree inspection in the afternoon of Sep 20, spoke & demonstrated the second time tree pruning at the CGLF Board Meeting that immediately followed, & then attended the Guest of Honour Dinner in the same evening. Even at breakfast before his departure on Sep 21, the SM was still crowded by the participants for many many questions. Every minute of his presence was desperately wanted.

The success of the SM on this trip can be accounted for by his fluent Mandarin & profound knowledge in Arboriculture, from tree production to design, installation, maintenance, inspection, protection & consultation. He can practically answer any question thrown at him on tree care in China. The SM is currently the highest qualified Arborist in Asia & is an ethnic Chinese. He has worked widely in our territory since 1984. This helps very much. Although such are his merits but, the SM is already approaching the retiring age. It is very important that our second generation of Arborists can soon come & take over on our course. It has been the continuous task of ISA HK/China to train up our younger generation to maintain the steam on the Arborist Profession. It may take some time to train up leaders like the SM, but Rome was not built in a day. We must insist.

The Chinese Authorities are pragmatic administrations not bound by any colonial past to accept what is good for them in their greenery development. Practices in China are very different from HK. HK will not be the model for China in developing the Arborist Profession. Our brothers up north are intelligent enough to make the correct decision. Cultural & historical sentiments bear an important part in this development. Commercial interest is another consideration. There are practically millions of "Tree Experts" working everywhere in China. To win their hearts & gain their support would require great skills & eloquence among them.

ISA HK/China has been discussing with CGN to hold the first regional conference for Modern Tree Care in China . The response has been positive, although running such a new venture there would require to overcome many hurdles. Protectionism is still strong in China among the traditional practitioners. The academics have their own knowledge & thinking. It will take great efforts to win an event as such.

ISA HK/China will relentlessly promote the Arborist Profession & ISA in our territory. This is our objective & nothing is going stop us from now.

best regards,

ISA HK/China --- China Tree News (Contemporary Tree Pit Design) 现代树穴设计

会员们:

附上图片所看到的, 是国内目前流行的树阵设计。 从表面上来看, 确实是充滿了时代气息, 香港八十年代的设计,有些与此非常相似。

作为一个树艺行业工作者, 我们知道大自然里树木的根部伸展, 往往是由中心发根点, 平均往外辐射到超过了树冠滴水线的切面之外, 作为抗风站穩和吸收水肥。 此外,根部往下的伸展,大部份都长在泥土一米的深度之内, 因为再往下走就没有氧气, 根也长不活了。 在松软的泥土里面, 土壤颗粒之间是充滿空气和水份, 那里的吸收根会长得特别多特别好, 对地上部的养份供应充足, 树体会长势茂盛。 反之者, 如果泥土被压实板死, 土壤颗粒之间的空气和水份都被挤压出去, 泥土的密度大得连新生根都长不进去, 哪树根只会在树干下面团团转, 自然的产生 "盘根效果", 造成上重下轻, 风雨一到, 自然塌下。

看图1和图2, 那四边凸起的 "座椅", 不就等如四张闸刀一样, 把树根的伸展, 牢牢的卡死在 "座椅" 的匡匡内吗? 树根还可以长到树冠滴水线的以外吗? 哪树冠长大以后, 当受风程度增加以后, 此树能站得稳吗?

再看图3, 树穴以外都铺了一层又厚又重的花岗岩表层, 在它下面的泥土, 颗粒之间的空气和水份, 早就被挤压一光了, 这里的土需要压实平整, 来承托上面花岗岩和行人的重量, 其密度之大, 会令新生根无法往外开展, 造成的效果就与图1和图2一样, 创造了 "盘根效果"。

明白了科学理由以后, 我们要决定我们的设计是想要什麼, 是要一个有 "即时效果" 和 "好看" 的树阵, 还是要一个有安全、长寿和省工省钱去管理的树阵? 聪明人会怎样决定啊?

谨此致意!

Dear Station Members,

Attached is a recent set of photos in a China newspaper, giving admiration to the Tree Pit Design so shown. Particular attention was given to the elevated boarders of the planting area to serve as a seating location for the visitors underneath.

It is noticed by Arborist that the weight of the "seats" would serve as a chopping gate to enclose the viable planting soil to within the less than 1 m x 1 m growing area inside. The weight of the structure would likely wipe out any macrospores in the planting soil, to completely eliminate any air or water pockets, with which the absorbing roots will need to survive. The soil directly under the "seats" would also be compacted to a bulk density so high, that any root penetration to beyond would be impossible. Therefore, the tree roots would be confined to within the tree pit, & may perhaps produce Girdling Roots in a few year's time. Girdling Roots are known to constrict tree trunk to kill tree.

Another effect is that as tree canopy continues to grow & expand, the Girdling Roots underneath have nowhere to spread for safe anchorage. A top heavy structure is then produced. In time, it will come to a point where the wind may topple the tree. This would usually happen in storm. Would the tree owner then claim it an "Act of God" ?

Practically millions of tree pits as shown are now installed in China, as well as in HK. Many will turn into Time Bombs in time.

Good luck to these beautiful Tree Pits in our territory. May they stay safe in our cities, especially in those with typhoons.

best regards,

ISA HK/China --- Chicago trees in October 2011 2011年美国芝加哥市的市区树木种植

会员们:



附上的图片是副分会长梁永强和王卓粤, 在2011年参加 "ISA领袖训练班" 时, 在美国芝加哥市内拍到的。 本分会从来都致力培养第二代的接斑人, 也为发展树艺行业努力不懈, 只愿我中华大地到处种上优质树木, 改善社会生活环境, 也能为广大纳税人省工省钱。



图片上很多的成年树, 其实栽植时间与国内许多大城市里开始搞绿化的时间也差不多, 大概也是30年左右吧, 但从这些树木的树体结构、整体健康和绿化效果来看, 与我们的来相比, 却有相当大的差別。 看起来芝加哥的种树要求是重"质", 而不是重"量", 他们会在合适的地点种上了合适的树种, 给地上部份合理的修剪, 给根部有足够伸展的空间, 也给予时间和耐心去让小树长大成荫, 种树的目的着眼在长期效果,而不是 "即时效果"。 这样子, 30年后得出来的结果是一份份的社会资产, 而不是一个个的 "不定时炸弹"。



芝加哥的市区种树,从30年前开始到现在, 都是由他们的 "市立树艺师", 从设计、栽种、护养、检查和保育, 来全盘负责,再由其他行业辅助。 芝加哥人爱树, 也同意树艺师是懂得护理树木的专家, 完全把市内种树交给树艺师去打理, 得出来的成绩是有目共睹。



树艺行业在大中华地区尚未发展起來,凭我中华民族的智慧和毅力,理应很快可以建立起來。 但愿有一天同样的文章能被某国外专家,写上在我某大城市里的树木种植, 能够让他们国家来取经。



如此的日子, 希望不离目前很远。



谨此致意!

Dear Station Members,



It may be a little bit late, but attached are the photos brought back by our Deputy Station Managers Mike Leung & Chiky Wong, during their trip to the ISA Leadership Workshop in Chicago, Illinois, USA in October 2011. ISA HK/China is giving every opportunity to our second generation of Arborists to train themselves to carry on what we have built since 2005. We are here to build the Arborist Profession in our territory of HK, Macau, Taiwan & China. We need to advance our next generation to continue on what we have developed.



In the photos, please note the quality, the spacing, the species selection, & the end results of the tree planting in Chicago. Also note the trees are not that old, perhaps planted at around the same time, to a lot of the mature trees in the cities of HK & China. Then please compare the contribution of the Chicago trees with a lot of our existing trees. Which one is the asset?



It is known to us that the urban trees in Chicago are monitored by their City Arborists from design, installation, maintenance, inspection to protection. Their Arborists have done a fine job, well to be admired by any tree care specialists all around the world. How we wish we can have trees similar to theirs in our territory.



It is important that trees are placed into the hands of the correct professionals. Trees are long living. They may not give an "instant effect" of the mature trees just after installation. They also take a long time to show any damage, & would enter a "spiral of decline" gradually to total failure. People who do not know enough about tress would pack trees like in a refugee camp for an "instant effect". Some even pulled out mature trees from a forest into the city to try to buy history. Then the trees will eventually take revenge.



Design & installation are usually the most critical stage of any tree planting. If done incorrectly, Mother Nature makes the Rules. Look around us for our city trees in our territory. Are they giving us the end results of the trees in Chicago, or as in Portland as shown before? Do we need to ask ourselves why? Are we using our Arborist Profession properly?



Give trees back to the Arborists. Let the right professionals look after our urban trees, or Mother Nature will make the Rules in the long term.

Dear Station Members,

ISA Certification Department has recently published an article on Certification & Qualification. This article is now attached for our Station Members viewing with ISA Cert Dept's blessings. Please kindly take note on the subtle differences between Certification & Qualification, & its recognition internationally.

In our territory of HK, Macau, Taiwan & China, only HK practices the British format of qualification due to our colonial history. When ISA HK/China brought the ISA Certifications such as Certified Arborist, Certified Tree Worker, Board Certified Master Arborist, etc. into HK in 2004, these credentials have been taken up as the same as Qualification, & are given in contract specifications & requirements.

Outside HK in the rest of our territory, the translation for Certification & Qualification into the Chinese language & its understanding, is practically the same. The Station Manager would hesitate at this early stage to advise our China brothers & sisters that, there is indeed a subtle difference between the two, as no ISA credential is recognized in the China tree care system so far. This may confuse them to further their hesitation. Therefore, this message is not translated into Mandarin in our Station Mail system, & is not circulated into China.

Taiwan & China are both trying to start up the Arborist Profession, with the Station Manager helping as their Chief Adviser so far. It has been going on smoothly, although not always reported in our Station Mail system. As far as we can say, Taiwan will begin the Arborist Profession hopefully by this December, & China may be within a year or two. The Station Manager is heavily involved with the design & politics of the Arborist Profession in both places. We are steering our course very carefully. To us, there is no point of announcing glory. We just want to see the right things done. When the profession can begin there, all will benefit.

In time, the advanced ideas & practices of the West can be gradually brought in to grow in our territory. HK is lucky to have most of our professionals understanding English, maybe not so in the rest of our territory. Less than 0.1% of our brothers & sisters in China can manage English to a level of most of the HK Certified Arborists. This is a reality in our place.

ISA HK/China will continue to develop & advance the Arborist Profession in our territory as our duty. With it installed, we can talk about everything else.

best regards,

Sammy Au

By Marya Ryan ISA Director of Certification
HEADQUARTERS’ BULLETIN

Qualifications, Certifications, and International Recognition of Credentials

With the planned rollout of ISA’s tree risk assessment qualification, ISA is setting out on a new path. We have twenty years of certification experience behind us, but we are learning quite a bit as we venture into qualifications— including where our new type of credential fits in globally.

Qualifications Versus Certifications

In the December 2011 issue of Arborist News, we outlined the difference between the two types of credentials. Key differences are summarized below.

ISA Qualifications

ISA qualifications are currently being developed under the American Society for Testing and Materials (ASTM) E2659-09 standard. The plan is for ISA to develop a number of qualification programs over time. We envision the programs to comprise a few days of training, immediately followed by an assessment. For each program, we will establish a period of validity based in part on how frequently new knowledge and skills are developed in each subject area. Once that period has expired, a person will have to take the program again to ensure that they have received training in current knowledge and methods. Programs will vary to some extent, but we anticipate that most of them will follow this model.

Because qualifications are so different from certifications, we are developing a separate set of policies and procedures for them. For instance, certification policies require a strict wall of separation between the exam and preparatory training. Anyone who sees exam questions is not allowed to help candidates to prepare to take the exam or to develop

any training materials. By contrast, a qualifications instructor will usually be very familiar with the exam and might even administer it. This is because the program focuses on a specific set of learning outcomes that need to be tested. Again, by contrast, certification exams focus on testing a broad body of knowledge that a person gains through education and experience.

ISA qualifications differ from certifications. They share important similarities with qualifications offered worldwide, but they also have their own unique characteristics that make them different from the types of qualifications that people in the United Kingdom (UK), New Zealand, Australia, and elsewhere may be familiar with.

ISA Qualifications and National Qualifications Frameworks

The UK, New Zealand, Australia, and several other countries have well-established national qualifications frameworks, tied to their educational frameworks. Under these frameworks, a qualification or set of qualifications has a status similar to a diploma in the United States. In fact, diplomas and other academic degrees are usually included within the national frameworks. The frameworks define various levels, from basic through highly advanced, and designate which qualifications satisfy the requirements of each level.

Qualifications under these frameworks differ from the qualifications that ISA is developing:

• In both cases, qualifications are tied to well-defined, measurable learning outcomes; however, under the national frameworks, a specific training program is not always an integral part of the credentialing pro-

A summary of the difference bet ween qualifications and certifications.

Qualification Certification The exam assesses a defined set of learning

outcomes. The exam assesses a broad body of knowledge.

The program includes training as an integral component.

Assessment questions may be well known to trainers.

Trainers may assess their own trainees, depending on the requirements of a given program.

Qualifications may be valid for life, but many have a set period of validity. Credential holders must retrain and retest at the end of that period if they want to continue to hold the credential.

Certification is independent of any specific training program.

Exam questions are shielded from anyone teaching preparatory courses or developing preparatory material.

Trainers may not assess their own trainees.

The credential is periodically renewed, subject to recertification requirements, such as participation in continuing education opportunities.

cess. By contrast, ISA’s qualifications require a training component. • The period of time required to obtain qualifications under the national frameworks typically varies from several weeks to several years; ISA qualifications will be tied to shortterm training programs of several days’ duration, with the possibility that there may be programs that combine a series of short trainings. • The national frameworks often include provision for recognition of prior learning without undergoing a specific training, where ISA credentials will require training as part of the program.

• National-framework qualifications are typically good for life; although some ISA qualifications may be good for life, most will have a set period of validity, after which they will expire.


International Recognition of Credentials

Under the UK, New Zealand, and Australian frameworks, equivalences can often be made between credentials issued one country and those issued in another country. As we develop ISA qualifications, we seek to establish equivalencies between ISA qualifications and national-framework qualification levels. The possibilities are truly exciting, as they would help arborists who work internationally to have their hard-earned credentials recognized across national borders.

Establishing such equivalencies for qualifications will take ISA into new territory: We have not established any national-framework equivalencies for our certifications. Our certifications are recognized internationally, and they are fully transferrable among countries. In fact, the ISA Certified Arborist® credential is accredited under an International Organization for Standardization (ISO) standard. In spite of this recognition, employers are not always sure how our certifications equate with the nationally based credentials that they are familiar with.

It is important for our credential holders that employers can readily understand what knowledge and skills they bring to the table. Therefore, we have investigated whether we can equate ISA certifications to the various levels within the national frameworks. The short answer is that it is complicated; the types of credentials are not similar enough in scope and objectives. For example, unlike qualifications, certifications do not have a training component and are not tied to specific learning outcomes. Another important difference is that qualifications do not typically have a continuing education component, whereas commitment to continuing professional education is a hallmark of certification.

Even though we have not been able to equate ISA certifications to nationalframework qualifications levels, the Certification Board seeks to recognize national-framework qualification levels as eligibility criteria for taking certification exams. Qualification at an appropriate level would make a candidate eligible to take a certification exam, but the candidate would still have to take the exam.

With our venture into qualifications, we believe it will be easier to equate ISA qualifications to national-framework qualification levels. It is a new pathway that we are eager to explore. We continue research and outreach for mutual recognition of credentials across national borders to foster transnational recognition of expertise. It all comes back to the value we place on a robust global exchange of tree care knowledge and practice.   A•N

ISA HK/China (Professionals) --- 2012 ISA Portland Conference 2012年 ISA 国际树艺年会










国内朋友请查閱 "百度博客 --- 国际树木学会" (http://hi.baidu.com/%B9%FA%BC%CA%CA%F7%C4%BE%D1%A7%BB%E1/blog ) 以取得其他文章。本分会的发表文章都已放弃版权, 任何人都可以自由转载作为教育目的, 但不能作为商业目的盈利。 任何人仕都可以申请免費加入本分会, 本分会员名单从不公开, 有意者请将真实姓名、年龄、单位、职衔、最高学历、电邮和手机号传真到 +852-2679-5338 便可. 如有查询, 请电邮至 egc@netvigator.com   。 本分会发表的一切内容, 谨供参考。


会员们:

在2012年的8月份, 本分会长与几名分会员长途拔涉从香港起飞先到东京, 然后再转机前往美国俄立冈州的波特兰市, 单向飞行距离是10,000公里, 时差是15小时, 前往参加2012年的国际树艺年会。

有人问, 你们不是去年已在澳洲悉尼去过了吗? 干吗今年又去? 是否喜欢坐长途飞机和享受巔倒晨昏啊?

非也。 本分会各人自费前往参会, 主要为了三个目的。 第一是为了参观和参赛于 "国际攀树锦标赛" (ITCC), 2012年是本分会同时派出男女代表前往参加, 是历史上的第一次。 第二是为了参观 "树艺行业展" (Trade Show), 此等展览一旦离开美洲大陆就会变得小型很多, 因为众多大小机器都带不走, 而美国树艺供应商仍然是全球最大最多的, 美国是目前全球树艺工作最大量的单一国家。 目标第三是为了考察波特兰市的树木种植, ISA 不会茂然的选址开年会, 看一下附件里的树木图片便可比较一切。

在ITCC里, 本分会非常高兴的告诉大家, 男子组的我方代表李启宏 (凤溪学生、由本分会长亲手训练), 在双绳脚锁比赛当中, 取得了季军。 这是一个历史性的特破, 是第一次有亚洲的男性取得此国际殊衔,实是香港人的骄傲, 也是中华民族的骄傲。 李启宏今年才23岁, 在攀树生涯是如日东升, 我们祝他能百尺竿头, 更进一步, 继续为国家民族添光彩。

在行业展方面, 本分会长以前在全球各地也看过很多, 但比足球场还要大的室內展览, 从书刊到摆放18米升台机器的, 还是第一次看到。 美国好像甚麼都比亚洲的大一点, 一份主飧食就可供应亚洲一家四口吃饱。 从附上的图片看到, 这里连攀树示范用的7米高大树, 都可以被弄进室內展馆里, 无惧风雨。 在这里, 许多美国本土的树艺行业和顾问机构都趁此盛会自我宣传一番, 本分会长花了两天时间在会场内购买了50磅重的书籍报告和攀树器材,交了不少朋友, 可谓获益良多。

对本分会长个人来说, 是次行程的重中之重, 就是考察和比较波特兰市的市区树木种植。 为此, 本分会长故意不乘车而选择走路三天, 因为这样才能小心观察, 和记录下当地的种树方法与我们的有何不同。 如果 "一张照片胜过千言万语" 这句话是对的话, 哪各位请留意一下附上的图片 Fig. 1 - 8。

本分会长注意到波特兰市的街道宽度与我们的城市相近, 交通、水电和城市配套与我们的也不相伯仲, 但他们的树木种植和旁边的建筑物和其他硬件配套, 几乎没有冲突。 成年树的树冠不会伸展到建筑物的窗边, 而是保持约2英尺的距离。 再小心看一下, 这里的树龄都在20年以下, 换句话说, 他们比我们许多已经搞了绿化30年以上的大城市, 要种得还晚。 在三天的走路观察中, 本分会长没有看到好像我们城市里经常见到的不正当修剪, 危险树和烂树,也没有见到好像我们城市里经常见到的绿化工人穿着制服, 封道拦路的在列队修剪、打药和施肥。

为什麼会这样子啊? 是波特兰市的树木天生就不用剪, 还是那里的绿化经费不够用啊? 难道老天爷特別照顾这里的树木?

为了探讨这个问题, 本分会长故意参加了由大会主办的 "波特兰市城区树木一天游', 在那里与十多位当地专家交流过, 得出以下结论。

波特兰市的市区树木种植是独立的由他们的 "市立树艺师' 团队来负责; 从设计、选料、栽种、护养、检查、保育等等, 都是由他们来一手包办, 而并非其他任何行业。 本分会长为了看树, 都已经跑遍了大半个地球, 但这里的市区树, 可算是他见到的最好其中一批。 就经济效益而言, 这里的几乎不需要经常保养的市区树, 不单省工省钱, 更不会为社会生活带来不便, 招引市民投诉, 也不会每天制造大量残枝废物去塞满垃圾堆填区。

波特兰市的市区树木种植是充滿计划, 也很有长远眼光, 为的不是 "即时效果" 而去曇花一现, 对花费公帑也负上责任, 令到这个城市的树木种植令人焕然一新, 非常值得一赞!

明年的国际树艺年会将会在加拿大的多伦多市举行, 本分会建议持加拿大籍的会员不妨前往参加, 顺道探亲旅游, 一举两得。

谨此致意!

Dear Station Members,

It is our pleasure to inform you that after some meticulous planning, the Station Manager (SM) & a group of HK tree climbers, have embarked on a 10,000 km journey across the wide Pacific to take on a 15 hour jet lag, to attend the 2012 ISA International Conference in Portland, Oregon, USA this August. Attached are some photos of the SM taken at the International Tree Climbing Championship (ITCC), the Conference Proceedings, & the urban tree planting of the Portland City.

Before the trip, the SM was advised by overseas experts that there will be 3 major areas that he should focus upon. They are the ITCC, the Trade Show of the Conference, & the urban tree planting of the Portland City. Why? It was said that the ITCC & the Trade Show would be bigger while in the US Mainland, since the majority of the ISA Chapters are from the US. People don't need to go far to attend. Also, USA is the single country in the world with the largest Arborist Profession in practice. It is just a matter of convenience for the professionals & suppliers to attend. The conference venue in the US is usually more roomy than in a lot of other countries to hold large shows. Just look at their Elections. It is a tradition over there.

As for the urban tree planting, the SM was told to see it with his own eyes to make a comment. The SM has spent a fifth of his life overseas to look at trees. The SM paid attention to this word before he departed on the trip.

2012 is the first year that ISA HK/China has sent both male & female climbers to compete at the ITCC. We were very excited about it. And the result has been pleasing. KW Lee, the student of the SM in Fung Kai, scored a 3rd place in the Men's Footlock Event. This is the first time ever that a HK Climber has won anything in the ITCC. This has also proven our climbers can climb with the world's best. This is very encouraging. Well done KW, congratulation! Do better for us next time.

Next was the Trade Show in the Conference, & it was massive & indoor. The size must be bigger than a football field. It was so big that even a 20 ft tree could be brought in at the Climbers' Corner for climbing demonstration & seminar. The SM has never seen anything like it before outside the US. After spending two days walking around to collect brochures, books & tree climbing equipment, the SM was kicking himself for not bringing in the third suitcase. Nearly every major US supplier & arboricultural consultancy was present at the show. It was impossible to see them all for details in just a couple of days. It was an eye bubbling event.

The mystery of this trip for the SM personally was really to find out about the Urban Tree Planting of Portland. Why did the overseas experts say that to the SM? Then from the moment that the SM got down the plane to ride the train into the city, despite the agonizing 15 hour flight & jet lag, he was made wide awake by the superior tree planting all along the way. The trees here are different. The SM has seen trees in many places around the world, but has not yet seen a place where the trees are so neat, healthy, & free of defects. Out of curiosity & respect, the SM has decided to spend the next 3 days to walk around Portland City to see for more.

The attached Fig. 1-8 showed some of the street tree planting in Portland Downtown. It can be seen that there is hardly any conflict between the trees & the buildings. The SM, in his many travel around the world, has never seen a city where the urban trees are so designed, planted & structurally pruned to avoid conflict with the infrastructures of a city, in a sustainable manner. Portland has done just that. The residents of Portland can be very proud about their trees indeed.

The SM has also noticed that the majority of tree planting is under 20 years old. He could not see any one of them has structural defects or obvious hazards. The SM also did not notice any army of maintenance staff, wearing uniform & brandishing tools & machines, to work on the city plantings anywhere like in our cities. The City council must have saved a bomb. But does it mean that the Portland trees are maintenance free? How do they do that?

For this the SM has joined a one day tour of the Portland Society of Municipal Arborists to try to find out some answers. In his conversation with the experts, the SM has found out that the tree planting is the responsibility of their City Arborists, from design, selection, planting, maintenance, inspection to protection. The City Arborists have their own system of planning, contracting & management, & they are all true experts in the field. This may be something our territory can use as a comparison, & perhaps even learn from them. If trees are not on the hand of genuine experts, then it will be "Mother Nature makes the Rules". Facts speak better than a thousand words. No exception.

In review, the Portland trip has been a very educational experience. If the SM did not go, then he did not see. Our tree climber could not have brought back the glory. We have opened to the world for advanced knowledge. We have made networking with international experts to learn their experience. We have advanced ourselves.

The 2013 ISA International Conference will be in Toronto, Canada. ISA HK/China would encourage all those Station Members who hold Canadian passport to attend. It will be a homeward bound journey for them, plus a chance to share among the profession. ISA HK/China would certainly want to go.

Hope to see you all in Toronto next year.

best regards,

Dear Station Members,

As our development with Arbor Japan is now strengthening, ISA HK/China is now planning a visit to go to Japan early next year to deliver seminars & Tree Work demonstrations to our Japanese counterparts, to try to help them to develop an Arborist Profession over there.

For this purpose, ISA HK/China is currently seeking a Japanese speaking Station Member, if any, to come along as our escort on this Japan Trip. This person must have been a Station Member for over a year, so that he/she would understand how we function; must speak Japanese fluently, & preferably possess some form of Arborist credentials &/or Tree Climbing skills. He/she will work with the Station Manger closely on conducting this trip, & he/she may be asked to help with the translation during the seminars & demonstrations.

As for this hard work, ISA HK/China will offer free travel & accommodation to our Japanese speaking Escort for this trip, to show our appreciation for his/her contribution. Please note that all of us are working in ISA HK/China as volunteers only, & everyone else on the trip will pay his/her own costs for everything. This includes the Station Manager too.

If anyone is interested in this offer & meeting our requirements, please kindly reply this email or contact the Station Manager at 9090 6719. All your information will be treated in the strictest confidence to until you are on the trip with us.

best regards,

Sammy Au

会员们:

本分会很高兴的告诉各位, 本年度的 "香港攀树锦标赛", 将会在2012年11月17-18日, 在香港马安山的 YMCA 度假村里面举行, 详情请看各附页。

为了隆重其事, 本分会的 "周年晚宴" 也会在比赛结束后同时举行, 而这次"攀树锦标赛"也将会与 "香港国际树艺研討会" 同时协办, 令香港成为目前能举办如此树艺盛事的唯一远东城市。

举办攀树比赛的其中一个目的, 是为了寻找更新更好的树上工作技术和装备, 令高空工作能够更安全, 更有效率。 攀树是树艺行业独有的工种, 也是目前所有绿化行业当中缺乏的训练,没有了攀树,高空修剪会变得很困难, 攀树也令树艺行业者在所有绿化工种之中独树一幟。

在日后条件成熟以后, 本分会冀望 "攀树锦标赛" 也能在两岸四地的大小城市里面举行,为此目的,本分会必然全力以附。

谨此致意!

Dear Station Members,

It is our pleasure to inform all of you that the HK Tree Climbing Championship (HKTCC) will be held on Nov 17-18, 2012 at the Wu Kai Sha YMCA Camp in Ma On Shan, Hong Kong. Details of the event are given in the attachments.

This year, the ISA HK/China Annual Dinner, the HKTCC & the International Arboricultural Summit of HK (IASHK), will join hand together in the same period to create the biggest Arboricultural Event in our territory of HK, Macau, Taiwan & China. We shall also extend the invitation to our regional counterparts & tree climbers to come & join us for networking & sharing. More information on IASHK & our Annual Dinner will be issued in our weekly Station Mail later.

Tree Climbing is an integral part of Arboriculture, & is a unique skill of the Arborist Profession. It is like a doctor operating surgery. Tree Climbing is also exciting to watch. From international experience, any Tree Climbing display usually draws a large crowd to applaud the agility of human to mimic animals to maneuver intelligently in a tree canopy. The swings & jumps from branch to branch earn amazement from the audience. It is also a sport so authentic to make the cameras click & snap repeatedly below.

Tree Climbing Competition is a way in finding new skills & equipment to improve the safety at work in the tree canopy. New climbing techniques are frequently tested out in the competition. New gears are comparing themselves with traditional tools. The best are taken out for future use. It is a way to upgrade the industry to advance both knowledge & safety.

ISA HK/China invites everyone to come to support the HKTCC. You can make it a family day out. The weather will be nice at the time & the ground is roomy to spend a day out in leisure. The venue is easily accessible by public transport, & car parking can be made available by prior arrangement. More information of the event is given in the attachments.

As for those who will be competing in the HKTCC, please ensure yourselves to send in the registration before the deadline. The winners of the Master Challenge will become the representatives of our territory to compete in the regional Tree Climbing Competition, & ultimately in the International Tree Climbing Championship. It will be an honour for life.

Looking forward to seeing you all at the 2012 HKTCC. It will be an event that everyone will remember.

best regards,

Sammy Au

ISA HK/China --- Aftermath of Typhoon Vicente on 23.7.2012 台风 "韦森特" 2012.7.24 掠过香港以后












国内朋友请查閱 "百度博客 --- 国际树木学会" (http://hi.baidu.com/%B9%FA%BC%CA%CA%F7%C4%BE%D1%A7%BB%E1/blog ) 以取得其他文章。本分会的发表文章都已放弃版权, 任何人都可以自由转载作为教育目的, 但不能作为商业目的盈利。 任何人仕都可以申请免費加入本分会, 本分会员名单从不公开, 有意者请将真实姓名、年龄、单位、职衔、最高学历、电邮和手机号传真到 +852-2679-5338 便可. 如有查询, 请电邮至 egc@netvigator.com  。本分会的一切发表内容, 谨供参考。


会员们:

台风 "韦森特" 於 2012年7月24日凌晨时份, 在香港的西南面约130公里处掠过, 虽然它没有正面吹袭香港, 但对市区里的树木则带来严重破坏。按照传媒报导, 截至7月26日为止, 政府方面共有2,000 宗以上的塌树报告, 过 7,000 棵的树木被吹倒或吹断,这可能是香港有记录以来,市区树木被损坏最严重的其中一次。

除了附上的图片以外,更多的有关是次树木损坏的消息, 可在下述连结看到:

1. http://news.sina.com.hk/news/2/1/1/2727384/1.html

2. http://orientaldaily.on.cc/cnt/news/20120728/00176_065.html

13年前香港也经历过一次10号风球, 当年的台风 "约克" 只是造成了 282 宗的塌树报告, 而在1999年, 香港并未有推行 "树木评估' 和 "风险减免" 等等树木管理工作。 如今的香港已推行了 "树木评估' 、 "风险减免" 和 "全民验树" 等活动已经3年, 为何这次倒树却是 13 年前的 7 倍多? 是否又把它推到 "自然灾害" 的解释当中?

传媒揭发了有倒树的土球连包装袋都没有拆掉, 在小树洞里种上大树, 许多断落的品种属於 "脆木" 树种等等,这又可否算得上是 "自然灾害" 吗?

"韦森特"过去了, 但不能肯定恶梦已经完结。 许多倒下挡路的大树, 给建筑工人或园丁干脆的砍掉拦路的枝干部份,用的切法往往是 "去顶法", 这可能会令树体结构被切底破坏。 树顶被风吹撕裂的伤口如不及时处理, 日后会造成内部腐烂。 倾斜的树体如不马上扶正支撑, 会造成日后倒塌, 变成危险树。 但过去数天本分会长所见到的, 只有普通工人在现场工作,并没有看到有树艺师在现场监督,这又可以吗?

受破坏的树木如不及时获得正当处理, 可能会变成都市里的 "不定时炸弹"。 树木的设计、种植、护养和检查, 如果不交由 "树木医生" 的树艺师来承担, 最终只会是 "大自然去决定成败', 而不是由任何人!

谨此致意!

Dear Station Members,

Typhoon Vicente skimmed passed HK at early morning of July 24, 2012 at about 130 km southwest (http://www.weather.gov.hk/wxinfo/currwx/tc_pos_1210.htm ). The widespread destruction it has done to the urban tree planting is seen to be unprecedented in the memory of the Station Manager (SM), ever since he came back to live in HK in 1984. From the photos sent in by Station Members, the urban trees in HK seemed to have been bombed. Fallen trees & broken branches were everywhere. Roads were obstructed by them for days. Properties were damaged & the traffic was slowed down because of the failed trees. Public discontent was high, & the media have attacked for days on the event.

One media reported on 26.7.2012 that more than 2,000 cases of tree failures were reported to the authorities (see attached), with some 7,000 trees fallen or broken. More information of this can be viewed at the following links in Chinese :

1. http://news.sina.com.hk/news/2/1/1/2727384/1.html

2. http://orientaldaily.on.cc/cnt/news/20120728/00176_065.html

The last No. 10 signal typhoon to hit HK was in September 1999. Unlike Vicente, the Typhoon York hit HK directly on the front. However, from the media report in the above links, there were only 282 cases of tree failures reported to the authorities. No "Tree Risk Assessment" (TRA) or "Risk Mitigation Measure" was carried out at that time. HK has begun TRA for more than 3 years since 2009, & many trees should have their "risks" removed or reduced. Then why does HK have more tree failures (nearly 7 times!) after TRA now, than before without in 1999? The SM has been asked this question by the media, & could not answer.

If the tree failures of Vicente are to be entirely blamed as an "Act of God", then the media has discovered that some fallen trees did not have their rootball wrapping removed during planting, large trees were planted in small planters, & a lot of the broken branches belong to the "brittle species" with weak wood in the design. Then can all these be called an "Act of God" ? The SM could not answer any of these questions again, & told the media to seek them from the authorities instead.

Now Vicente has passed & it may not the end of the nightmare. Many failed trees were "topped" away to allow traffic through. Many leaning trees were not erected immediately. Broken branches at the tip of the canopy have been left untouched which can lead to decay. Some trees may have their internal fibers torn out by wind but are still standing without external symptom displayed. Other trees may have their roots torn in part, but not failing for the moment. If these structural defects are not picked out & corrected immediately, the damaged trees would simply turn into Time Bombs to cause more "Act of God" in future. Yet some of the hidden defects would need expert eyes to identify, & the work would take time & cost to complete. Does HK have the resources?

In the past few days, the SM has seen tree clearance work started by the contractors. He has not yet seen one case of an Arborist supervising the work (90+% of the Arborists in HK are our Station Members), but rather, he has seen mostly construction workers & common gardeners operating chainsaws to top & cut without adequate PPE. Does it mean that the correction work will be done again in future by Arborists to rectify the defects? If a tree is topped, can we still "structurally prune" ?

Urban trees in HK may never be the same again after this Typhoon Vicente. Maybe we need to think of why for the next time.

Would HK now place Arborists to be in charge of tree planting from design, installation, inspection to protection, or let Mother Nature make the Rules yet again in future?

best regards,
