The following are questions commonly asked by people
interested in tree climbing. Read the answers with an
understanding that opinions vary and not all aspects of
each perspective can be addressed.
Welcome to our first recreationally based tree climbing
catalog. After 22 years serving the urban tree care industry
(not loggers) it’s refreshing to witness a generation interested
in bonding with, rather than fearing trees. During my career,
I’ve witnessed a growing apathy about trees and their
importance to our existence, not just in foreign jungles
but right here in the states. Absolutely breath-taking and
healthy trees that share space in cities around the USA are
too often mutilated or sacrificed over little more than the
inconvenience of shedding, or worse, an often unfounded
fear of catastrophic failure (leading to death of course). I
believe that the joy of tree climbing might just be the catalyst
to reverse these conceptions and encourage a new age for
trees everywhere.
Throughout this catalog you’ll see an array of techniques
that are practiced daily by professionals. The purpose of
displaying illustrations clarifying these techniques is not to
teach, but to expose. You’ll have to discover the nuances of
these techniques by learning from climbing instructors, or the
many tree experts in the field today who may emerge as the
ultimate tour guides of tomorrow.
You’ll also occasionally see two icons in
the pages that follow. The technical difficulty
icon represents products that require
advanced training and skills that should be practiced close to
the ground before employing aloft. The Tobe’s Choice icon
tobe’s
CHOICE
represents my favorites or popular choices
by customers on items where more than one
version exists.
That’s all from me, enjoy yourself, climb safe and please,
be considerate of trees, nature, public and private property, and
of course other people in your journey to connect with trees!
Tobe Sherrill, President
Q. Does climbing hurt trees?
A. Today’s tree climbing techniques are regularly
performed without hurting trees. No spikes, power
saws or gaffs are used or welcomed. Noninvasive
techniques even include chafe protection for ropes
to eliminate bark abrasion! Regardless, trees are
quite hearty, and we believe, have far more to gain
from human interaction than existing without it.
Take for example this storm-downed elm living in a
park in Amsterdam Holland. Blown over by heavy
winds several years prior, it endures a constant
stream of foot traffic from both children and adults.
Upon close review I was convinced the tree couldn’t
be much healthier and, given the circumstances,
much happier. Contrast that with the trunk of this
White Ash in my local park bumped only once by a
sloppy contractor and the issue is clear.
tranquility base.
Q. Is tree climbing dangerous?
A. Yes, although the risk is easily minimized through use of a well proven and quite
learnable self belay system. Proper tree climbing is performed using no less than
two safety lines; a primary line for overhead support and a secondary lanyard
employed whenever resting at an angle or detaching from the primary line. Other
important safety steps include making a thorough hazard assessment before
entering a tree (see page 45), wearing personal protection equipment (PPE) and
of course, receiving proper training about system use and safety procedures.
Q. How do I know if a particular limb can support my weight?
A. Generally speaking, tree structures are incredibly strong. Even small,
ornamental trees are known to withstand enormous stress from ice, wind and
yes, even climbing humans. Think back to the last time you walked on a limb
or swung from a branch to reach your own conclusion. When climbing a tree,
it’s always advisable to keep your body weight and line draped on branches
as close to the trunk as possible, at least until you’re comfortable with the tree
species’ inherent strength and flexibility.

Q. What are the best trees to climb?
A. To start with, I’d have to say that for every old-growth conifer you see in the
pages of this catalog (Sequoia, Redwood, etc.), there are millions of as technically
challenging, scenic, majestic and, usually much easier to access, climbing trees
sprinkled throughout all parts of this and other countries. Many of the oaks and
poplars tucked away in parks on the east coast are just as interesting structurally as
the biggest trees in the world. Once you start viewing your community as the ant
does a weed, your whole perspective of “neighborhood” may change dramatically.

knowledge of several more...
Memorize the acronym
TDS by relating it to
tying your shoes. First
you TIE the laces, then
you DRESS the knot by
aligning all parts, and
then you SET the knot by
pulling firmly, important
to assuring a knot
performs as intended when a load is applied,
such as running. Of course you should frequently
monitor any knot involved with life support to
make sure everything remains aligned.
The Blake’s hitch is used
as a self-belay friction
hitch within a tree
climber’s primary support
system. The end of line
is basically tied back to
the standing part of rope
to create an “adjustable
loop” for ascending and
descending (see page 15).
Once tied and dressed
you’ll need to apply
tension (on the snap
end here) and then pull
the knotted tail (image
2, left) to properly set
the hitch. If additional
holding power is needed,
add a 5th wrap to the coil.
The Blake’s is also a very
effective hitch for day to
day tasks.
STORE POLICIES

CALL-IN ORDERS will be taken by Sherrill employees
during working hours (Monday through Friday, 8 a.m. to 6
p.m. Eastern Standard Time, except on holidays). If you have
specific questions about merchandise, please call during working
hours. Night calls are taken by Telephone Answering Service of
Greensboro. We can’t ship to a post office (P.O.) box, so please
let us know if your shipping address is different from your
mailing address. Changes in orders may delay shipping. When
calling back to change an order, it would be helpful to ask for
the same operator who took the original order. All additions or
changes to your original order must be made within one hour of
placing the order. Otherwise, shipping could be delayed at least
one day, depending on the change.

The figure 8 is
commonly used to
secure a rope to a
rope snap in this
traditional “tail tied”
method because it’s
easy to untie following
significant loading. It
also serves well as a
stopper knot in the end
of line, lending some
assurance that the tail
doesn’t creep back
through the Blake’s
hitch. The Figure 8 is
NOT designed for life
support when used as
a terminating knot (last
knot in a rope’s end).
INTERNET ORDERS can be placed 24 hours a day, 7
days a week at www.sherrilltree.com. Our website is secure for
credit card use. Orders placed after 2 p.m. Eastern Standard
Time, or on weekends and holidays, will be processed the
following business day.
C.O.D. ORDERS can no longer be paid in “CASH”
due to UPS and FedEx policy. They both now require a check
or money order made payable to Sherrill, Inc. C.O.D. fees
currently run $7.50 per package, in addition to regular shipping
charges. C.O.D. orders rejected upon delivery or “not in on 3
attempts” will put the customer in “Cash in Advance” status for
following orders, with shipping fees still owed. C.O.D. orders
exceeding $500 must be paid with a certified check or money
order.

BOWLINE
The bowline (step 2)
is a great rigging knot
and unique in that it can
be heavily loaded and
then, when off tension,
easily untied. But this
easy-to-untie feature
is a negative when it
comes to life-support
because in the wrong
conditions the knot
can loosen between
loads, making it a poor
choice for life support.
To combat this, some
tree climbers include a
securing measure called
the Yosemite tie-off
(step 3-4).

list, look to see if this particular item has a number in the “B.O.”
column. If it does, the item is on back order, and we will ship it
the day that we receive it, unless otherwise specified. “Hold to
ship complete” requests by you may delay the order, so please
discuss with a Sherrill employee before making this request. We
do not currently call customers to inform of back orders. Back
orders ship UPS or FedEx ground unless customer requests
special delivery.
RETURNS If you are not satisfied with a product purchased
from us, please feel free to return it, unused, within 30 days, or
restocking fees may apply. Call for authorization first. Insure
your return shipment; Sherrill is not responsible for damages
incurred or the loss of package during transit. Direct shipments
are returned to Sherrill, not the vendor. Upon receipt of the
unused item(s), we will give you credit for the full purchase

Although rope-assisted tree climbing has
been going on since the turn of the 19th
century, the great majority has been work
oriented for both care and research. As other
means of training and education evolve, you’ll
find them listed at sherrilltree.com.
TRAINING OR ADVENTURE
For complete information about tree
climbing and instruction, go to Tree Climbers
International TM. TCI and its affiliates offer
comprehensive training for beginners to
advanced climbers, as well as fun events for
individuals, families, and groups!
RETURN SERVICE LABELS, or “prepaid returns”
are issued only in the event of an error on the part of Sherrill,
Inc., or as a prepaid request by our customers.
DEFECTIVE OR INCORRECT
MERCHANDISE If you receive defective or incorrect
merchandise from our company, please call us within 3 days
of the delivery, and upon return, we will send a pre-paid (by
Sherrill) shipping label, as well as the correct item without
additional shipping costs (once the incorrect merchandise is
returned). It is often discovered that the item number shipped
is identical to the one on the invoice, indicating that the wrong
number was given to the operator or a description was offered
instead of the stock number. In this circumstance, shipping costs
will be the customer’s responsibility. Also, when the order is
delivered to you, we suggest that you inspect the package(s) for
damage before you sign for the delivery or open the package(s).
A package must be signed for as “damaged” to process a claim
for replacement, and the boxes must be kept for inspection.

new climber to decide which throw weights,
line and storage will work best for them. To
make this selection easier, we’ve grouped the
essential components together, while ensuring
that your kit has the key tools you’ll need for
this important first step in tree climbing.

The trick to precision throwline
technique is matching line size
to proper weight (see throwline

can be thrown higher than a heavier

brush. Heavy bags can be quite helpful
once line is placed to manipulate a

The Big Shot
TM
Once you’ve mastered the
steps to hand-casting an
accurate throwline into the
highest branches in your
range, you might decide
on the Big Shot as your
special reward. I developed
and patented the Big Shot
to convert the power of
a simple slingshot into a
recoilless weight launcher.
This unique 8-foot catapult
allows you to launch weights
with great accuracy into the
tallest tree canopies, piercing
through brush and other limbs. The straight up
throw is virtually impossible through the standard
hand throwing technique, making the Big Shot
a big must for truly adventuresome climbers.
Includes (2) 4' poles and head.

Q. How strong does my climbing equipment need to be?
A. Throughout this catalog we report the “rated
tensile strength” of products that may be involved
in personal support. In the working world, ANSI
(American National Standards Institute) outlines
that climbing hardware have a tensile strength of
5,000 pounds and rope 5,400. This leaves room
for dynamic loading in case of errors or slippage.
My suggestion? Follow these guidelines when
shopping for any product involved in personal
support.
Q. When’s the best time of year to climb?
A. Generally speaking, in seasons when the tree
29290 $19
Hard Plastic Carrying Case. (4lbs.) 16418 $39
is past its most active growth stage (all seasons
but spring), when the new cambium layer has
strengthened and sprout growth has matured
from buds to rubbery twigs. Although most
thick-barked trees are unaffected by animal
traffic in all seasons (that means soft shoes
for humans), thin-barked trees like beech and
maple can experience damage if the cambium
is scuffed or torn in its early growth stage. As
for the best times for humans I’d have to say
summer (in the neighborhood), fall (in the
mountains), winter (somewhere lakeside) and
spring (anywhere the wind blows for “tree
surfing”).

WARNING!
“Over the past six
years the Big Shot
has very simply
changed the way
people climb and
care for trees.
Good line position
is key to a safe and
productive climb.
Great invention,
Tobe!”
Mark Chisholm (USA)

Tree Climbing Champion
(Men’s Division)
We strongly advise that you never launch rocks or
other rigid objects and never launch projectiles toward
people or animals. Be sure to examine the landing
area for potential hazards. Vertical launches should
be attempted only when visibility allows a clear view
of the projectile’s return. Only Sherrill’s utility grade
fiberglass poles should be used with the Big Shot.
Read instructions carefully before using the Big Shot.
If you have any questions about using the Big Shot,
please call.
Q. How about people with a fear of heights?
A. Oddly enough, rope-secured tree climbing has
been discovered as one of the most effective
acrophobia-breaking excrcises around. Time and
again people with fear of heights report that the
ability to ascend and descend close to the ground
while securely attached to a life line has been
a helpful cure for often deep-seated fears. The
eventual journey into the canopy? Just a bonus!

tree climbers are only

STEP THREE:
Tree Climbing Lines are different
from others because they must function in a unique selfbelaying configuration that, so
far as I know, doesn’t exist in other
climbing practices. Tree climbing lines
are not dynamic, having very low
elongation (2%) compared to many
rock and wall belay lines (upwards of
30% elongation). Yet, even though
they can be considered static,
tree climbing ropes have an amazingly
supple hand (rope talk for softness and
flexibility), to make knot-tying a breeze
and constant hand to rope contact more
comfortable.There are many variables

Recreational Tree Climbing
By Parke Puterbaugh
Back at the dawn of the surfing craze, the
Beach Boys celebrated the thrill of the sport with a
song that went: “Catch a wave and you’re sitting on
top of the world.”
Today, with recreational tree climbing poised
to break through to the public, those lyrics might be
amended to go: “Climb a tree and you’re sitting on
top of the world.”
around with a fresh set of eyes. It has been said
that you’ll never look at trees the same way after
climbing one. The first time you hang suspended
between a tree’s canopy and the ground below, open
to a breathtaking new world of visual and auditory
stimuli, you will know this to be true.
It is a pastime that’s climbing in popularity for
obvious reasons. Like the popular adventure sports
such as surfing, skiing, rock-climbing and hanggliding, tree climbing can be as challenging as you
wish to make it. Moreover, the activity is readily
accessible. Unlike decent rock-climbing routes or
rideable waves - resources whose limited supply has
been pushed to the limit by ever-increasing demand
- trees are plentiful. They’re as close as your own
back yard, and you don’t need a garage full of highly
specialized gear and attire to get into them.
Tree climbing is unique among outdoor
activities in the range of approaches it allows. These
can vary from ascending to daredevil heights with
competitive speed to
lolling in a lower limb
without a care in
the world. In
other words,
you can chase
an adrenalin
rush, pursue a
more sublime,
meditative
experience, or go for
something in-between.
Tobe Sherrill has savored both ends of the
spectrum. He has hung from a few hundred feet in
one of the West Coast’s largest Sitka spruces. But he
also loves climbing average-sized oaks in the parks
and neighborhoods of his NC hometown. He points
out that each season offers something different to
enjoy. “For instance, if you love a beautiful, cool fall
day,” he says, “you’ll enjoy it all the more up in a
nearby tree.”
The best part of tree climbing is that you get
to hang out, quite literally, in nature. For most
practitioners, competition and conquest aren’t
necessarily the point of the endeavor. It’s more
about opening up another dimension - the vertical
one - and surveying the world above, below and
of a tree, rest assured that contact by climbers is
incidental, negligible and non-damaging.
It is possible to learn how to climb trees from
printed literature but better to be tutored by a
professional. There are currently eight chapters of
Tree Climbers International in the U.S. and abroad,
and more trained arborists are getting into the
recreational tree climbing field all the time.
Doubled rope technique (DdRT). Tree climbing’s doubled rope technique is unlike most other
rope-assisted activities in that a single rope, draped over a fixed position (tree limb) is used to create friction upon itself (without mechanical
assistance) for both ascending and descending. This very simple self-belay technique uses the rope’s own end to both secure the climber during
ascent as well as control descent during rappel. The practice can very simply be described as an “adjustable loop” that the climber makes
longer or shorter to move in or out and up or down the tree. The images on this page illustrate a climber entering and then exiting a tree with some
of the more common moves associated with canopy exploration.

Like many outdoor adventures such as

once, occasionally or frequently, depending on one’s
level of interest and ability. Once you’ve tried it,
however, chances are you’ll feel the urge to get up
there again.

At what point can you call yourself a tree
climber? As soon as your feet leave the ground.
It has been said that you’ll
never look at trees the same
way after climbing one.
So exactly what is recreational tree climbing?
Basically, it means climbing trees for pleasure in
a safe and secure fashion using many of the same
techniques that professional arborists employ. Your
gear will include a tree climbing harness, a helmet,
arborist-grade rope, carabiners (metal clips), and
friction savers (which protect limbs from abrasion).
You will learn to tie particular kinds of knots,
“blind-folded” as Sherrill suggests. Finally, tree
climbing requires the ability to hoist oneself up a
rope, with a bit of technological assistance. It is a
pleasurable and rewarding exertion like few I’ve
experienced.
No, you won’t fall, either. A tree climber
is always safely secured by rope, harness and
carabiners. How safe is recreational tree climbing?
Having taken more than 50,000 people into
trees since its founding in 1983, Tree Climbers
International reports that not one serious injury has
occurred.
Moreover, the trees themselves are protected
from injury through the use of friction savers. And,
lest you worry what human limbs might do to those
With running, some people jog around the block
while others run marathons at a five-minute
pace; most, however, fall somewhere in-between.
Likewise the International Society of Arboriculture
sponsors an annual International Tree Climbing
Championship that attracts professionals. Then
there are simple nature lovers who like to hang ten
feet off the ground in a backyard pine tree. And
most of the rest of us fall in the middle.

I received an introduction to tree climbing in
my own back yard. In a few short minutes, I found
myself happily hanging 80 feet up in a rugged old
red oak. I was impressed with the “roominess” of
the tree – particularly the cathedral-like quality of
this peaceful green-leafed and gray-limbed space,
filled with birdsong and the sound of rustling
leaves. I experienced what is known as “tree time”:
a slowing down of the mental clock that typically
keeps us scurrying from one earthbound errand to
the next. Up in a tree you become synced to a clock
that ticks at a more deliberate pace. You notice the
stratification of plant and animal life. A limb can
look like a short hiking trail, and there’s no reason
not to step out and explore it. And there’s no hurry
to come down. The rat race can wait.
The traditional tailtied method of DdRT is
essential to a tree climber’s
knowledge base.

NICE EFFECT!
The Marbar system was developed by Washington state
arborist Paul Sisson in the late ‘90s. As an aging student of
ArborMaster Training, Paul, then in his mid 40’s recognized
his physical limitations when climbing multiple large trees
each day, and set out to fulfill the need for a rope ascending
“ladder.” Today, working arborists as well as competition level
tree climbers employ the Marbar system because it saves
time and energy. Why? Because the system can be quickly
attached on doubled rope, used to ascend to the supporting
branch where switchover occurs, and then quickly detached,
leaving the doubled rope ready for traditional attachment.
Although this system is ideal for production pruning I find it
less appealing for the 1 or 2 tree-a-day ascents because of the
cost. Two pairs of ascenders and the hardware to complete
the handles is understandably expensive, even for production
climbers. It’s a good reason to learn to footlock (a skill that’s
handy to know anyway) and then purchase only the upper
set for hand-gripping. If you already have a pair of CMI
Ultracenders (large) you can purchase the handle kit alone.
The Marbar System with ascenders works on 11-13mm.

The Micro Pulley attached by a snap below the knot in this
diagram acts to “tend” the friction hitch. Generally, when
climbing a tree with rope, you must pull once, then advance
your friction hitch, over and over until you reach the top.
This can be tiring, especially if you are climbing a very
tall tree. The Micro Pulley advances the knot, so you only
need to pull the rope through it, exerting much less energy.
Another popular technique allows the climber to hand haul
himself up while a person on the ground pulls the slack line
through the pulley as fast as the climber advances.
During the past several
years a number of
climbers have embraced
the 2-eye split tail for
climbs that include a lot
of horizontal movement
in open canopy. The
leading advantage of
this technique is how
smoothly the climbing line falls through a few advanced friction
hitches like the Distel hitch (illustration left), the Valdotain and
Machard Tresse. Petzl’s William carabiner and Fixe pulley make a
sweet fairlead combination when configured underneath the hitch in

Regardless of prowess, people do love to get
into trees once they’re introduced to the idea. Peter
Jenkins estimates that among the many thousands
who have come to his Founder’s Grove site in
Atlanta, less than 1% never get into a tree.
“A lot of people say they are afraid of heights,
but they find out once they’re high in the tree that
they enter into what we call ‘moments of peace’,”
says Jenkins. “I used to be a rock climber, and tree
climbing is not like that, where you’re hanging by
tooth and nail from hand and finger holds you can
barely even see. It’s a restful, peaceful experience.”
I experienced what is known
as ‘tree time’: a slowing down
of the mental clock that typically
keeps us scurrying from one
earthbound errand to the next.
The mounting interest in tree-climbing
couldn’t come at a better time, both for people
and for trees. Our urbanized society has largely
abstracted itself from nature, to the detriment of our
mental and physical well-being. The culture of the
indoors - which keeps us confined to homes, cars
and office cubicles - has led to a disinterest verging
on disregard for nature. More from ignorance than
malice, the natural world is often viewed as little
more than a source of raw materials from which
to fashion the consumer products that stoke our
lifestyles.
As noted ecological writer/philosophers
John McPhee and Bill McKibbon have argued,
respectively, this has resulted in “the control of
nature” and “the end of nature”. The disconnection
between man and nature in modern times has
had dire consequences for the world’s forests. Ten
thousand years ago, 15.4 billion hectares of trees
covered the earth. That figure had shrunk to 9.7
billion hectares by 2000. In other words, there are
one-third less trees covering our planet today.
More alarmingly, remaining semi-natural and
old-growth forest is only 1-2% in the United States
and less than 1% in Europe. One-fifth of the world’s
tropical forests have been cleared just since 1960.
Rainforests are being lost at the rate of 214,000
acres a day – an area equal in size to New York City.
Atlanta, GA, which once touted itself as “the City
of Trees,” has lost 40% of its urban forest due to
rapid development. In Greensboro, NC - where
Sherrill Arborist Supply is headquartered - nearly
one-fifth of the urban forest has been lost in recent
years as ever-more land is cleared for often treeless
development.

The destruction of forests is hard to fathom
given the multitude of benefits that trees afford us.
According to the U.S. Forest Service, the strategic
placement of trees around homes and buildings can
reduce heating and cooling costs by 30% or more.
The cooling effect of a healthy tree is equal to ten
air conditioners operating around the clock! The
benefits of trees to human well-being are staggering.
Scientists who translate biological functions into
monetary worth estimate that a single tree provides
$62,000 worth of air-pollution controls over a
50-year lifetime. In a similar time span, a healthy
tree recycles $37,000 worth of water and produces
$31,250 worth of oxygen. Trees dramatically reduce
soil erosion and stormwater runoff. They provide
habitat for birds and wildlife. Trees even serve as
sound buffers, reducing noise levels by half. You
might say that good trees make good neighbors!

today.
Tree climbing is as
old as humanity itself.
Human life evolved in and
descended from the trees.
Even after learning how to
survive on the forest floor,
our forebears would retreat
to trees as a “safe haven.”
Even in recent times, the first
thing the average kid would
do when he or she got old
enough to play outdoors was
climb a tree. However, in
our increasingly cloistered,
urbanized society, trees and
the urge to explore them
have declined.
While Doubled Rope Technique is
the way to go for short asscents
and canopy scouting, SRT is the
hands down preferred choice for fast,
energy-efficient ascents of 50 feet
and higher. The more traditional of
Peter “Treeman” Jenkins
founder of Tree Climbers
International
It’s a truism that people
cannot miss something they’ve never known, and
with great tracts of the natural world disappearing,
so has the experiential awareness of and ethical
regard for nature. A world of healthy forests,
clean air and water, deep wilderness and thriving
ecosystems is something we have every right to
demand, but for recent generations who have been
denied these things, awareness and support must
be cultivated. One way to start is by reintroducing
people to their primordial “safe haven.”
In other words, get them up in a tree.
The positive news is that there is growing awareness
of these facts and broad support for greater
environmental stewardship. It is their belief at
Sherrill that by bringing average people into contact
with trees, recreational climbing will raise awareness
of our priceless natural heritage and support for its
caretaking. They will learn something that working
arborists have known for a long time: that trees are
great places to hang out, and that keeping them
happy and healthy is a way of doing the same for
ourselves. That is why Sherrill is entering the
recreational field with this catalog.
“Until they experience a tree, a lot of people
see them as things that drop branches, leaves,
acorns and fruit, and you’ve got to pick up behind
them,” says Peter Jenkins, founder of Tree Climbers
International. “You can shift the whole paradigm for
a person with one climb in a moderately sized tree.
It’s almost instantaneous. They have this pleasurable
adventure, and suddenly trees become more
personal. People start looking up and taking notice,
because the possibility has been given to them. It
opens a lot of doors.”
It’s heartening to see what happens when
a child or adult ascends a tree for the first time.
There’s a sense of delight, discovery and, on some
subliminal level, recognition of what once was a
primordial safe place. “I’m firmly convinced it’s
programmed and imprinted in our genes,” says
Jenkins. “There’s a psychological kick-in that occurs
when people get up there.”
On the West Coast, with its towering redwoods
and Sitka spruce, recreational tree climbing began
catching on about 30 years ago. With the dawn
of the environmental movement in the late sixties
and the establishment of a consciousness-raising
annual “Earth Day” in 1970, it was only natural that
recreationists would take to the trees. The founding
of Tree Climbers International in 1983 was a pivotal
event. The many chapters of TCI today include
a thriving one in Japan, where recreational tree
climbing has become extremely popular.

Sherrill’s Tree Frog Climbing System
Of course we rate our own first. And for
good reasons! We checked out all the existing
systems and adapted the best features of each
to create our own definition of excellence.
We’re certain this system will work well for
you too. Our mantra while developing the
Tree Frog was “simplify, simplify, simplify”.
It’s easier to attach, adjust and operate, and
takes up minimum storage space. Once in the
canopy, most SRT climbers switch over to the
DdRT because it allows fluid and immediate
change of direction, either up and down or
in and out, and the Tree Frog makes this
transition a breeze. The recommended extras,
a Pantin (foot ascender) and Croll (chest
ascender) can be worn throughout your climb
without interfering with your DdRT system.

The Texas
Climbing System
This SRT system is the most
basic of all, with each part stitched
together into one compact kit.
From a sitting position (on the
upper ascender’s tether) the
climber brings both heels under
the buttocks and stands, lifting the
upper ascender as they go, then
it’s basically a sit, stand, inchworm
motion until reaching destination.
Although the technique is
effective, it’s slower than other
systems because here, two legs
act together as one. The good
things about the system are: it’s
easy to learn; it is very compact
(portable); and requires the least
amount of time to engage and
disengage from line. Separate

Handled ascenders are beloved by climbers because even if you’re old,
overweight, out of shape and crazy enough to climb really high, they save
energy. They lock in one direction and can be pushed, nearly friction free
in the other. We offer three choices: each can be attached midline on ropes
measuring 9 to 13 mm. and have a spring-loaded safety latch that is manually
tripped to insert or remove rope. The ascenders are left- and right-hand
oriented, constructed from lightweight aluminum and have formed handholds
for comfort. The Petzl ascenders feature slightly curved teeth which are more
effective in ice and mud, while CMI has straight, conical teeth which are less
damaging to rope. If subjected to a high load (2,000 lbs. plus) these ascenders
are known to tear or destroy most ropes. Use with caution! Wt. 1 lb. per pair.

STEP SIX:
The Line on Lanyards.
The positioning lanyard, also known as a safety lanyard or buckstrap,
tobe’s
CHOICE
is a vital component of tree climbing safety. Used when performing
tasks while standing in a tree (shooting pictures, making hardware
adjustments) this lanyard can keep you from swinging wildly in case of the
unexpected; as I once experienced flinching for a dropped handsaw. More
than just a secondary safety, the positioning lanyard is also useful as primary support during
switch-overs from SRT to DdRT or while redirecting your climbing line.
Grillion Lanyard
This is an adaptation of Petzl’s popular Grigri
belaying device into a unique lanyard. It’s my
lanyard of choice because it allows the climber to
release line even while under significant tension.
The lanyard includes an anti-friction sleeve that cuts
down on self-abrasion. Carabiners not included.

Microcender Caming Lanyard

helpful when dealing with branchy or slippery trees where

is secure yet easily adjusted on the lanyard, oh, and easy
to replace when worn. 16-strand braided rope (10'), hip

disadvantage? The hitch will usually be
in the most difficult to reach position
when it’s needed most. Weight 1.6 lbs.

It’s in the Bag. As all who use synthetic rope know, lifeline storage is serious
Sherrill I.D. Rope Bags
business! There’s nothing more frustrating than deploying a lifeline only to discover an entangled rat’s
A-D. Our most popular bags are double-
nest midline. Climbing and rigging lines are best stored and deployed when flaked into a pile in what I call
FPO
“orderly disorderness”. The rope should be fed hand over hand,
piled onto itself in a manner that allows the rope end to literally be shot
from a cannon without entanglement. Our better tree climbing rope
bags include stiffeners that keep the bag standing while you load rope.
They’re usually recognized by strap material running vertically up the
outside wall. Other features to consider include additional pockets
for storing non-rope items. I often choose a rope pack large enough to carry 200 feet of rope, harness,
helmet and lanyard.

around in your pocket and practice until you can open and close it blindfolded. Carabiners generally
come in two shapes: a modified D (smaller of the two) and HMS (designed for performing the Munter
hitch). Both have various uses, but generally speaking, I lean toward the smaller, higher-strength, d-shaped
variations. We offer a variety of lightweight aluminum carabiners (mostly for climbing), and heavier-duty steel carabiners
(rigging applications). kN represents kilonewtons, a European strength rating system that reflects dynamic loading. To convert
kilonewtons to strength in pounds, multiply the kN figure by 224.8.

able to let go of line and rest without the
object falling to the ground. Both work
on ropes 8 to 13 mm.
M-N. The side plates on these pulleys
have a square edge that acts to block
the coils of a prusik, producing a prusik
minding effect. The double sheave
version has an auxiliary attachment point
for attaching rope and producing up to
4 to 1 mechanical advantage.
These high strength blocks are ideal for tensioning lines
or lifting heavy objects. With very little set-up time you
can produce 5 times the lifting power of the weight of the
object to be raised. A built-in rope cleat allows you to hold
the object between strides of pull and release tension, bit
by bit or all at once with the flip of a wrist. Includes one
cleating and one non-cleating block, 50' of 1/2" 16-strand line
with spliced end, two non-locking carabiners, a prusik and
instruction. SET82 $199

Petzl Swivel
Continued from page 18
Tree climbing requires a
lot of moving around on
the rope and that usually
means a lot of twisting. For
most climbers, the worst
time to untwist your line
usually occurs when you’re
in the most precarious
position. Although rarely life
threatening, this untwisting
activity can be inconvenient.
Petzl’s precision swivel uses
sealed ball bearings inside a
strong forged body designed
to relieve line twisting in
many circumstances.
TS-8,000 lbs., 5 oz.
Another development that put tree-climbing on the radar
was the adoption of “tree sitting” - the practice of climbing and
occupying a tree to protest and prevent logging of old-growth forests
- as a tactic. A two-year sit-in by Julia “Butterfly” Hill atop a majestic
thousand-year old California redwood brought widespread attention
to the preservationist movement and, indirectly, to tree climbing.
A number of professional arborists assembled in 2003 for
an organized recreational tree climb - the first of its kind to bring
together so many notable figures from around the world. The group
gathered in the Bogachiel River Valley, located in a rain forest near
the coast inside Washington’s Olympic National Park. They took
turns climbing a 250-foot Sitka spruce, setting an elevator line at 175
feet as well as running a zipline that allowed them to ride a “rail”
above the treetops.

Nine of the participants even spent a night “tree camping”
– that is, sleeping suspended from a tree using a PortaLedge,
hammock or tree tent. Mike Kraus – owner of the Hawaii-based
Tree Works and father of climbing champion Dan Kraus – spent two
nights in the Sitka spruce at Bogachiel. He had this to say about the
experience:
F
“I camped about 155 feet off the ground, which left me above
the canopy of the surrounding forest,” Krauss recalls. “So it gave me
the position of being 40 or 50 feet above a kind of dream meadow
all around me. I was all alone by myself above the trees with a full
moon shining and a creek flowing below me. Gorgeous, gorgeous,
gorgeous...”
Dynema and Nylon Loop Runners
Most often used in a choke configuration, loop runners have many uses, from
creating a foot position, hanging a pulley, to redirecting lines. As portable as a
handkerchief, they’re as strong and durable as rope. Because they’re circular,
you’ll rarely clip into the same spot twice, which maximizes service life by
distributing wear evenly. Dynema (high strength to bulk ratio) loop runners are
the latest addition to our selection of the best available.

One piece of equipment that I simply can’t be without is my Spyderco. Whether trimming

Intelligently designed, precision made, easily maintained and constructed of the highest quality
materials, Spyderco continues to earn the outdoor person’s hands down seal of approval.
Temperance
A serious entry into the martial arts world, this

Delica
My personal favorite, the Delica, features the Spyderco
trademark thumb hole that lets me open the blade with one hand,
even in the dark. Formed from a combination of high grade carbon and
steel, the blade holds a razor sharp edge. The lightweight Zytel handle is
made of a nylon composite reinforced with 33% glass fiber. The patented
“volcano grip” texture keeps it securely in hand. Closed length - 4".

The Bogachiel get-together,
sponsored by the Northwest Chapter
of ISA, was a pilot project of the Tree
Research and Educational Endowment
Fund, and it bodes well for the future.
So does the popularity of
ecotourism operations in places like
Costa Rica, where ziplines allow people
to experience the wonders of the Central American rainforest. As
ecotourism gains popularity worldwide, recreational tree climbing
and zipline riding will provide the means and access into wondrous
high places.

Once you give tree climbing a try, you will likely become a
tree-hugger, both in the literal and figurative senses. Hoist yourself
up and have a look around, and you’ll see what we’re talking about.
There is nothing holding you back from the experience of a lifetime
except a harness, helmet, rope, a few clips and a bit of knot-tying
know-how. Up in the trees you’ll discover a world of beauty and
wonder you might never have guessed existed so close at hand.

New School
vs. Old School
Tree Support
Some traditions last because
they are sound, while others
last because people just
don’t know better alternatives.
Since the 1900’s, if an American
homeowner was concerned that a tree near their
house might fall and damage property, the typical
response by tree experts as the only alternative to
cutting the tree down, was to cable the tree. This
involved stringing steel wire between the limbs, often
healthy ones, by using metal screws and corrosive
hardware. Not satisfied with these options, modern
experts looked to Sherrill for a newly emerging
noninvasive, flexible product called COBRA, being
utilized throughout Europe and other parts of the
world as the preferred form of limb restraint.
Two of the most
commonly used cable
anchor products in the
US require installing
corrosive steel hardware
into an otherwise
healthy patient.
Non-invasive cabling systems cradle branches
and stems to provide gentle, dynamic support
during inclimate weather.
Advanced tree experts in the US are now
familiar with the COBRA dynamic system that has
quickly become the option of choice due to its many
advantages. In addition to causing no harm to the
living parts of the tree, the synthetic ropes provide an
elasticity that reacts to inclement weather like wind
and ice by gently cradling the branches and stems as
they move. The old systems would respond to snaploading forces with wires and anchor hardware that
greatly restrict the movement of healthy limbs and
stems. Wire can’t absorb shock loads when limbs are
swinging in the opposite directions so the steel cables
are installed taut, actually discouraging the tree’s
natural inclination to build strength. With dynamic
systems like COBRA (yes, others exist), the ropes are
installed slackly so the tree may continue its natural
tendency to pile reactive wood onto weak areas. They
are attached around the stem in a patented method
developed to prevent girdling or the hampering
of growth. COBRA, like any manmade restraint
installed in a living tree, requires annual inspection. If
adjustments are required, the ropes can be moved and
repositioned without damage or growth interference.
The bending motion of
trees in high wind proves
that static wires are
poorly compatible with
flexible green wood.
Made in the USA from a
Swedish formula, this long
term, year-round protection
for your garden emits an
odor that animals like deer,
rabbit and elk associate
with predator activity. Not
unpleasant to humans,
Plantskydd creates a strong

providing enough sway to help the tree develop
trunk strength. ArborTie® fastens to any stake or

PROPER PRUNING 101
The art of pruning is less about
the cut, and more about how trees
compartmentalize wounds to defend
against microbial invasion. The best
books to read on the subject are New
Tree Biology and Tree Prunning by Dr.
Alex Shigo.
For a quick lesson we let the tree do
the talking in the illustration above,
showing just where the dead wood
begins and live wood ends. This tree has
already begun the process of rolling in
its branch collar to compartmentalize the
wound. Cut only the dead wood and as
low as possible, NOT the living collar!
