当本分会长正在广州华南农业大學里, 挑选为2013年5月19日攀树锯木溜纜表演项目用的大树的时候, 他碰到一批当地的专业锯树队, 正在清理一批不想要的大树。 本分会长好奇的参观了他们的工作, 也和锯树工人们交谈了半个小时, 得益良多。
据这批老师傅说, 他们最年青的都在40岁以上, 以前在老家, 是在林区里伐木为生, 全都干了20年以上了。 再看他们的装备, 用的是欧洲名牌电油锯, 与西方國家使用的不相伯仲, 唯一的分别是他们讨厌那把链刹的存在, 认为它既无用又阻档视線, 也说不明白为何贵上几倍的电油锯, 竟然存有如此的设計盲点。
再看一下他们如何打开倒树切口。 他们把大概只有3英寸宽的倒树切口切开在只有离地數英寸的地方, 刚好能把电油锯贴地面操作, 为的可能是一举把大树倒下, 不须要採用较安全的分段切落法。 他们的做法除了危险、难控制以外, 也不好操弄电油锯, 因为实在太靠近地面了。 如果一不小心, 工人很容易就会把鋸链卡住树干上, 不上不下, 结果因快得慢。
此外, 他们做背切的方法也与全世界不同。 国际上的一贯做法, 是把背切开在倒树切口的正对面, 让逐步深入的鋸切慢慢的令倒树切口形成铰键, 然后大树会一步一步的向著倒树切口的方向往下倒。 在他们这里, 广州师傅们轮流的从倒树切口的旁边地方, 一点一点的往后拉切, 由于要避免夹鋸的情况出现, 他们切切仃仃、仃仃切切, 切一下又竭一下, 时间可能把他们遗忘了。 本來只虽5分钟的工序, 他们干了20分钟都没有完成一半, 然后就竭著抽煙了。
本分会长试图解释一般的國际锯木做法, 毕竟本分会长也用了电油锯 29 年有多了吧。 但是老师傅们是充满了自豪感, 一句 "内外有别", 就胜尽本分会长的千言万语。
看完以后, 本分会长的心里是充满祝福，但愿此等老师傅们经常工作安全平安, 也感觉到广州的专业锯树工人真的与世界非常不同啊 !
另外, "中华树艺师学会" 方面已經定好 "会徽", 详情如附件所示, 希望各会员们支持使用。 在中间 A 字头顶的两片小叶, 代表著本会在兩岸四地正在萌芽发展, 蓄勢待发 ! 在 "会训" 方面, 也將会沿用过去9年都在使用的 "诚信、专业、参与、找寻事实、道出真相" 五個重点， 也是本会与众不同的地方, 树艺师要行为正直, 不能为钱写报告, 这是本行业的特性。

Dear Station Members,
During a recent visit to SCAU to select the trees for climbing & rigging demonstration on May 19, 2013, the Station Manager (SM) came across a team of professional tree workers cutting down trees in the campus. The SM spent half an hour to study their work & talked to them on their experience. He also took some photos of their dressing code & their work.
The SM saw a gang of tree crew all age over 40. The headman told the SM that they have all been working previously as loggers to take down trees in the mountains for firewood & furniture. That is also where they learned to use the chainsaw. Looking at their chainsaw, it was a famous European brand of fine quality. However, the workers did tell the SM that they have found the chain brake a useless nuisance to obscure visibility at the cutting bar. Good on them.
In inspecting their removal techniques, the SM saw the face notch was opened up only inches form the ground. This is an apparent act to try to cut as low as possible in one action, so that the crew does not have to spend time for several cuts by sections to take down the tree. The notch was only around 3 inches wide at the largest opening, & it was cut in at about 1/4 of the diameter of the trunk.
In their performance of a back cut, what intrigued the SM most was that instead of cutting at the opposite end of the notch to form a hinge to let the tree fall by its own weight, the crew were cutting alongside the side of the notch to edge towards the opposite end ! This is most confusing to the SM & he did ask why. Then the crew told him that "this is a safer practice".
When the SM asked how long they had spent on making the notch with the chainsaw so far. The reply was already half an hour. They intended to take down the tree in the next hour or so.
Since the SM was in a hurry to select the demonstration trees, he did not stay long with this professional tree crew of Guangzhou. The SM bid them good luck & safe work always, & then departed with his search.
China has a long way to go to compare with the world to do tree work. It is a different world out there to western practices. This is what our Station facing every time.
Our Station (ISA HK/China now & China Arborist Association in future) will continue to bring in proper tree education with comparison to our territory. One day we will succeed.
