Always use arborist ropes for climbing trees, not ropes intended for rock climbing or caving. Rock climbing rope dynamic rope is very stretchy and designed to take climber falls. Tree climbing ropes come in a variety of colors. Which color you choose is a matter of personal preference. For recreational climbing, bright ropes are easy to see, but the muted earth-tone ropes make the climber less obvious to people on the ground.

The availability of reliable information on tree climbing methods is critical for the development of canopy science and for the safety of workers accessing the forest canopy. To assess the breadth and quality of information contained in published climbing information, we performed searches in Web of Science and Google Scholar and evaluated 54 published sources on 10 predetermined criteria related to safety.
We found a high incidence of unsafe recommendations that, if followed, could result in serious injury or death. Common errors included recommendations for equipment not suitable for tree climbing, advocating methods suitable for rock climbing but that can result in falls and trauma in tree climbing, and outdated information that no longer reflects best practices.
We conclude by providing safety recommendations and a short review of tree climbing methods. This article thus serves as a guide for finding and interpreting best sources of methods for canopy access. The published literature is an important source of information on climbing methods for canopy ecologists. Since Perry first published on methods of access into forest canopies, the very science of canopy ecology has evolved at a dramatic pace, and published sources of information on canopy access have grown from one to dozens.
Over this same time period, canopy access methods have continued to progress with advances in technology and the development of new climbing equipment. Further, as climbing equipment and methods continue to change, so do best practices for climbing safety. Partly for these reasons, published sources vary widely in the breadth of climbing methods described and in their adherence to best safety practices. The purpose of this study was to meet that challenge.
Finally, we follow guidelines written by the American National Standards Institute ANSI as our benchmark for best practices and current safety standards in tree climbing. The entire system is designed to arrest the fall of a person climbing above the last anchor point Eng This is not a minor philosophical point based on aesthetics or personal preference. Inherent differences in the climbing systems create different physical forces on ropes, substrates and climbers and dictate the use of different types of equipment.
After performing all searches, we conducted a careful revision of the reference sections of each source to obtain additional publications.
Finally, we conducted a forward search in Web of Science from all references. We next obtained a citation history of all sources from Google Scholar inasmuch as this serves as an index of a source's visibility to climbers i. We then evaluated breadth of content by noting whether each source presented information on five primary climbing methods or topics: safety, climbing spurs, single rope technique SRT , doubled rope technique DdRT and aerial traverse.
To evaluate sources, two of us BF and WK independently read every source and recorded each occurrence that a particular criterion was mentioned in the text. Ambiguity in writing was also a recurring issue with important safety implications. Seven passages in five sources could be reasonably interpreted as advocating unsafe practices criterion Another six passages in six sources were too vague to be interpreted by experienced climbers and could result in misuse of equipment or methods criterion 5.
We found nine sources that mentioned a need for instruction, but failed to distinguish between rock climbing instructors and tree climbers with specific knowledge and skills required for training others in climbing trees. The authors of six sources advocated methods that could lead to climbers falling from trees 10 occurrences, criterion 7.
Another six sources advocated methods that could lead to a dynamic fall eight occurrences, criterion 6 , in which improper use of rope and harness configurations prevent the climber from falling to the ground but which can lead to serious impact and trauma occurring in the tree. We provide a complete listing of all minor and major safety deviations by source in the Supporting Information to help climbers identify and avoid them.
Safe climbing demands an awareness of the distinction between rock and tree climbing principles, but this distinction was blurred in many of the sources we reviewed.
This error is important from the standpoint of advocating unsafe practices and also underscores a larger issue in the tree climbing literature, namely a widespread and ongoing misunderstanding of basic tree climbing principles and safety standards. Several observations serve to reinforce this observation. How unsafe practices continue to surface in publications is important to consider.
We found no relationship between source age and the frequency of minor and major safety deviations. In other words, even new publications often contain bad information. We speculate on two potential reasons for this. First, there is an overreliance on citing early publications without careful consideration of the content, and some common errors carry over from one publication to the next. Technology changes rapidly in many disciplines, and tree climbing is no exception. These developments have improved climber safety and climber efficiency i.
Therefore, best standards for tree climbing change often, and it is important for climbers to remain abreast of current standards. For example, we found recommendations in our benchmark for safety, ANSI , that were already outdated due to changes in technology. Canopy access methods can be divided roughly into two planes of movement: vertical movement up into or down out of trees, and horizontal movement within tree crowns or between trees.
Specific methods used to move either vertically or horizontally include climbing with spurs, SRT, DdRT and aerial traverse. Because the amount of information available to new climbers can be overwhelming and varies greatly in quality, we review published sources on canopy access methods. Tree climbing spurs are metal gaffs that attach to a climber's legs by use of metal or fibreglass stirrups and leather or nylon straps and are used to ascend the trunks of trees Davis The gaffs point downward and puncture the surface of the tree trunk, providing traction as the climber steps up the trunk.
This step is made easier by first placing small diameter fishing line or a light cord over the desired branch, then using this line to pull the climbing line into place.
Choosing a method is largely a matter of personal preference and experience, although some guidelines are helpful to new climbers.
Regardless, setting a line takes time and there is no substitute for practice. Time spent using the separate methods for rope placement will only make this step in canopy access faster and easier. Due to the sheer variety of mechanical ascenders and related pieces of equipment, there is a nearly infinite number of ways to configure SRT climbing systems. Doubled rope technique differs from SRT in the relative position of the anchor point in relation to the climber.
In DdRT, one end of a rope is tied to the climbing harness, the rope passes over a branch, and the opposite end of the rope is attached to the harness by means of a friction hitch a knot or mechanical device that grabs the rope when weighted and releases when pulled downward.
As the climber pulls rope through the friction hitch, the length of rope above the climber is shortened and the climber advances up the tree Jepson Doubled rope technique allows controlled movements up and down ropes, which a climber can use to walk out onto branches by easily controlling the amount of tension or slack in the rope Jepson Until recently, the sole use for SRT was to climb ropes upward into trees.
Aerial traverse is a technique whereby climbers move horizontally between trees. Here, we briefly summarize critical points on safety. A major difference between SRT, DdRT and aerial traverse is in the climber's ability to test an anchor point before hanging on it. In SRT and DdRT, a climber can hang and bounce on a rope at ground level and thereby assess the strength of an anchor point before climbing on it.
In aerial traverse, a climber is already at height in one tree when she or he installs a rope in a second tree. Working at height, the climber has to gradually transition from supporting their total weight on the first rope that has been climbed and tested, to supporting their weight on the second rope and anchor point that have not been tested. As a rope is tensioned from slack to horizontal, the physical forces exerted can exceed the strength of the rope and can cause it or the anchor point to break Harris Also important to consider is that branches are typically stronger when pulled downwards than when pulled to the side.
Despite the inherent risks involved in climbing trees, safety receives infrequent attention in climbing sources. Similar standards exist outside the United States, and we recommend that climbers in other countries obtain the applicable standards. Below we highlight ANSI standards that were frequently overlooked in the sources we reviewed. Helmets for tree climbing must be capable of sustaining impacts from both above and the side and must have a chinstrap ANSI Arborist helmets are constructed to meet this standard, but not all industrial or rock climbing helmets are.
The minimum rated strength in kN is stamped on carabiners and other climbing hardware for easy identification. The properties of ropes for tree climbing have developed rapidly in recent years with the introduction of a variety of new materials and types of construction.
We advise climbers that DdRT, SRT and rock climbing methods require ropes with different properties and that ropes constructed and sold for rock climbing do not necessarily meet the properties required for tree climbing.
Inappropriate rope choice can lead to serious injury and death. Specifications for tree climbing ropes are provided in catalogues for tree climbing gear, but the onus is on the climber to carefully research the available options to ensure that a rope meets current ANSI specifications and is suitable for the intended use. ANSI regulations state that arborists will wear eye protection capable of sustaining shock. Eye protection that meets this standard is stamped Z Although we can understand that there are situations in which a climber may need to remove eye protection while climbing e.
Secondly, we recommend that novice climbers obtain proper training from experienced tree climbers who follow ANSI standards for equipment choices and best practices. Thirdly, training and regular practice in aerial rescue methods are essential for safe climbing. Fourthly, independent audits of existing canopy research programmes could help improve safety standards and prevent climbing accidents.
Finally, careful review of new manuscripts can improve the published standards available to future climbers. This study benefitted from comments and discussion with D. Brown, E. Forsman, K. Harms and C. We thank R. Dial for constructive comments that improved the manuscript. We were motivated by conversations in trees with B. Price and B. Siedenstrang helped with the tables.

You must position the firm line to ensure safety. Now, go to the free part of the tight rope over the circle. Haul the stable line and tighten it. After that, coil the rope for increasing force and pass through it above the limb for a few times. Continuing the process, once the rope coil end is near, pick up the sturdy rope again and wrap it at the same time. Repeat the procedure two to three times around the other tree limb. Then, climb down carefully, without taking off the rood as it creates tension.

Rope covers, hammock straps and tree-climbing accessories help protect a tree from rope scars. Tying a rope around a tree for a hammock, boat or animal tether can scrape or cut the tree's bark. Ropes used on branches for tree shaping, climbing or hanging swings cause friction and can wear through bark.
The damage may expose the tree to diseases and pests. A rope tied around a tree trunk, however, may constrict the tree and kill it. When placed between the rope and the tree, rubber hose reduces pressure on the bark and the risk of friction. The rubber hose pad method offers a quick solution if you need to support a weak trunk. Although this technique is often used on ropes stabilizing young trees, it still includes a risk of damage to tender bark.
Using flat straps with grommets to support a tree produces less risk of damage to the bark than the rubber hose technique, according to Colorado State University Extension. Use two to three straps to stake one tree. Thread ropes through the grommets, and attach the ropes to stakes driven in the ground. The straps cover a wide surface along the trunk, spreading their pressure against the tree.
Garden centers sell tree-staking straps. This method can be used to support a newly planted tree and to help straighten a tilting tree. Arborist and recreational tree climbing equipment suppliers sell specialized equipment for protecting trees from ropes. Some friction savers are flat straps up to 6 feet long; they can be attached to climbing rope to prevent tree damage and increase climbing safety.
Leather cambium savers follow the same principle as a rubber hose: The cambium guards keep rope off the bark. These devices, also called tree savers, are straightforward to use. Just feed rope through a friction guard, and place the guard over a branch or around the trunk, depending on how you want to use the rope.
Tree topping, high pruning and other potentially hazardous tree work is best left to professionals. Hammock straps made from flat webbing are designed to prevent bark abrasion. Different brands of hammock straps are available, and the straps are adjustable to create a snug fit without harming a tree. Adjusting the straps as the tree grows prevents girdling, which will kill the tree; a tight rope prevents the tree from obtaining nutrients and water. Check sporting good suppliers for hammock hanging kits; a kit generally includes two straps for slinging a hammock between trees.
These straps also work for suspending chairs and swings from trees. Gryphon Adams began publishing in Adams is a certified health educator and a massage practitioner. Skip to main content.
