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,
