康樂攀爬 挑戰《人在野》
小記每逢星期三晚都唔逛夜街,點解?因為要追睇《人在野》(Man Vs. Wild)。每集主角Bear深入不毛,表演絕地求生真人騷,見佢手腳並用抱樹幹、爬藤蔓,真係一步一驚心。講起求生,攀樹確實係其中一項必學技巧,而香港樹木學會便有專人教授康樂攀爬(Recreational Tree Climbing),一嘗猶如《人在野》主角般挑戰大自然!

點止爬樹咁簡單
「《人在野》主角Bear擅長徒手爬來爬去,但真正的攀爬運動必須加入輔助工具。」香港樹木學會會長歐永森(Sammy)指出,徒手爬樹只限於直上直落,如果沒有利用繩結製造支點,是無法於樹上橫向移動。他續道:「基本攀爬運動講求三大重點,第一是透過引繩上樹尋找設置支點的樹椏。接着是利用連接結將身體穩固綁緊繩扣,以及靠摩擦結令身體在繩上移動。最後要熟習身體推進法(Body Thrust),攀爬時躺臥身體、雙腳穩定樹身,同時一下一下拉動繩子令自己往上升。」

第1步 檢查樹木
攀樹前首先要檢查樹木有否枯、老、病、死,同時觀察樹椏有否蜂巢等。

引繩上樹的技巧在於將投擲包,以鐘擺方式拋上目標樹椏來製造支點。

第2步 引繩上樹

身體推進法:攀樹時躺臥身體,同時腰臀發力及雙手向上拉動繩子。

雙繩腳鎖法:重點在於雙腳繞繩子作踏點,手腳並用盤繩向上。

安全坐帶:主要承托腰部及臀部,兩側及背部繫有攀爬繩、安全短繩及分叉繩,方便作上落用途。

安全鋼扣:爬樹鋼扣必須是保險鎖式並能自動關閉,鋼扣使用時虎口位必須成相反方向,防止誤開。

安全帽及護目鏡:攀爬時可避免枝葉、樹皮、昆蟲等雜物撞傷頭部或掉進眼睛。

手鋸:無論職業攀爬或康樂攀爬都必須佩戴,但多於職業攀爬時作枝節修剪。

吊索爬法:俗稱「天纜」的吊索系統,利用爬樹繩在樹與樹之間製作滑輪穿梭其中。

職業攀爬演變而來
攀樹技術並非無中生有,Sammy解釋,有系統的攀樹活動可追溯至百多年前的北美洲移民潮。「當地人為了開拓土地而大量砍伐樹木,後來重新綠化栽種,他們卻無法爬到樹上進行修剪,於是想到利用繩子及滑輪懸掛木板載人上樹,發展成所謂『職業攀爬』。」而現今的康樂攀爬可說由此演變而來。此外,謹記活動前要檢查樹木主幹及枝莖情況,若然太細便無法承受攀爬者重量,還要留意樹上有否蜂巢、蟻窩等,避免發生危險。

考牌做攀樹師
康樂攀爬屬近年新興的戶外活動,由於大眾對樹木保育意識提升,令不少人透過爬樹來親近大自然。香港樹木學會便提供有系統的訓練課程,由淺入深讓學員掌握不同技巧,Sammy藉此分享箇中玩法:「康樂攀爬是適合一家大細的戶外運動,初學者會先認識如專用裝備、繩結方法、身體推進法等,到了中階便可學習尋找攀爬場地、用投擲包引繩上樹等,至於高階訓練則集中高技術攀爬方法,如雙繩腳鎖、枝上行走等。」學會同時舉辦相關課程如樹藝理論、樹上拯救等,學成後可考國際認可牌照做攀樹師,將樹木知識傳承開去。
學員分享
Jessica於4年間由零開始到考獲教練牌,今年更到訪美國挑戰巨樹。她形容:「一般人以為爬樹很吃力,其實只要靠繩結幫助,女孩子也能輕易爬到5米以上。這令我更有自信,希望能將攀樹的樂趣跟其他人分享。」

Recreational Tree Climbing Tips
以上影片乃youtube提供,與本站無關; 若無法觀看,可查看原網址

Tree climbing is a recreational or functional activity consisting of ascending and moving around in the crown of trees.
Free solo climbing
Use of a rope, helmet, and harness are the minimum requirements to ensure the safety of the climber. Other equipment can also be used depending on the experience and skill of the tree climber. Some tree climbers take special hammocks called "Treeboats" and Portaledges with them into the tree canopies where they can enjoy a picnic or nap, or spend the night.
Tree climbing is an "on rope" activity that employs a mixture of techniques and gear principally derived from rock climbing and caving. These techniques are also used to climb trees for other purposes: tree care (arborists), animal rescue, research, and activism.
Many different techniques (free climbing, self-belayed climbing with a Doubled Rope Technique, Single Rope Technique, and lead climbing) are used to climb trees depending on the climber's individual style, purpose, and preferences. Generally though, climbing is performed by lapping a long rope over a limb and ascending the fallen end using a friction knot tied from initial tie's excess "tail." The difficulty of any particular climb depends on many factors: the regularity of branching, the brittleness of dead wood in some species, whether the bark is rough or smooth, the width of the trunk and branches, the height of the tree, the location of the tree, and the weather are all factors.

Doubled Rope Technique
The Doubled Rope Technique (DRT or DdRT) is used to self belay the climber in such a way that the rope can be retrieved without going back up the tree. One end of the rope is fastened to the climber's saddle (harness), from there the rope passes around the tree and back to a friction hitch which is also attached to the climber. This system allows the climber to easily adjust the rope to provide a belay if free climbing, or to go up or down if hanging on the rope. As long as the climber is below the anchor and there is minimal slack in the system, any fall will be restrained. This system can be placed into the tree from the ground or the climber can advance the rope up the tree over the course of the climb.

Single Rope Technique
The Single Rope Technique (SRT) is used mainly for getting to the top of large trees which cannot be easily free climbed. With the adequate hardware, a throw line, an attached weight, and a launching system (e.g., a bow or slingshot), a climbing rope can be anchored to a branch very high in the tree. This is done by launching the weight (with the throw line attached) over the desired limb and tying the climbing rope to the unweighted end. The climbing rope is then hauled over the branch by pulling on the throw line. The line is anchored to the trunk or to the high limb itself by running one end through a closed bight made in the other end. The climber then ascends the rope using a set of friction hitchs or mechanical ascenders) to obtain the desired limb. With practice this method is typically fastest and requires the least amount of hardware. One drawback is that it does not necessarily involve directly ascending the tree itself, as the vast majority of the time spent climbing is ascending the rope, and not the tree itself. Additionally, it can provide greater safety to a climber over DRT or lead climbing techniques as the climber can rig the rope over multiple limbs when using a ground-level trunk anchor. In the event that one limb breaks, the lower limbs may stop the fall.

Anchoring in the Tree

Lead climbing
Lead climbing is employed by climber where points of protection are formed by girthing the tree's limbs with slings. Once the lead climber ascends the tree, he or she may create a belay or top rope anchor or else simply rappel down. In the event that an anchor is created, other climbers can subsequently climb the tree on belay without having to lead. Drawbacks to this method include the probability of hitting a lower limb or the main trunk in the event of a fall. Due to this risk, climbers typically wear climbing helmets.
