Have you ever sat and watched a tree swaying in the wind? Sure,
many of us have on a nice, cool, summer day. Now imagine studying
that tree's canopy movement using 3-D motion tracking - like a
video game showing how a tree, its branch structure and leaves
billow in the breeze, analyzing each fraction of movement.
And what if this type of tool can actually help you determine
how stable that tree really is when it's being shaken by air
currents or even how much strength is sacrificed in the
process?
What could this do for an arborist? A lot. It can help them
better assess safety risks when climbing and pruning a tree. It can
even help them determine the entire pruning plan to do what's
necessary to restore or retain that tree's normal strength. What
does this do for you - the person enjoying the tree on a daily
basis? Even more. It means you get to watch that tree grow happier
and healthier and stronger for a longer period of time, adding
value to a property and providing all the benefits for which trees
are best known.
This was just a tiny fraction of the deep and meaningful tree
studies that took place last month during the Tree
Biomechanics Research Week and Symposium, presented by the International
Society of Arboriculture and sponsored by Davey Tree, The TREE Fund, Busy Bee Services, BioCompliance
Consulting, Utility
Arborist Association, Arboricultural Research and Education
Academy (AREA), U.S. Forest Service, Ohio Chapter ISA, Ohio
Division of Natural Resources/Urban Forestry, Sherrill Tree and Stihl. The goal of the event was to share the
latest advancements and fill in some known gaps in tree research,
giving attendees a chance to see demonstrations and experiments in
progress.

Attendees from around the world, including Great Britain,
Germany, New Zealand, Australia, Hong Kong, Canada and the United
States, formed 12 research teams and collaborated on 22 projects at
the Davey Research Farm in Shalersville, Ohio. In addition to
studying wind's affects on trees, projects included studying
the effects of pruning on tree strength (both branch and root
pruning) and analyzing the load bearing capacity of healthy versus
decaying or damaged branches.
The merger of arborists and researchers - the people who climb
the trees and the people who study the trees - was probably the
best part of the Tree Biomechanics Research Week & Symposium,
says Davey Resource Group's Manager of
Utility and Urban Resources Ward Peterson.
"Climbers and researchers don't normally work together," he
explains. "But here climbers who never have chances to share
research ideas got a chance to do that, while researchers were able
to shovel mulch and watch climbers in action and come up with new
research ideas as a result."
To further foster collaboration in the field and expose
practicing arborists to the experimental process, Peterson said
they set up idea boards with questions written on them to build and
capture new ideas throughout the week. They handed out Post-it
notes so attendees could jot down concepts and put them on the
boards. "When people are too focused on what they are doing, new
ideas don't come," Peterson says. "Here, we tried to give people
the space, time and resources to be able to think of new
ideas."
The entire event was structured to stimulate biomechanics
research, which Peterson says is just coming into its own. While
biomechanics may sound like the name of a Transformer, it's simply
the process of understanding tree strengths and structures.
Speaking of Transformers, one of my friends is a big comic book
enthusiast. And every year, he gets excited for Comic-Con - a national convention for graphic
novel groupies. People attend as their favorite comic book
characters from heroes like Superman to villains like Lex
Luther.
But at Tree Biomechanics Research Week & Symposium, famous
tree researchers with PhDs who normally don suits and ties and
stand at the front of lecture halls were instead wearing blue jeans
and t-shirts and shoveling mulch. Peterson says it was remarkable
to watch.
This was the first Tree Biomechanics Research Week &
Symposium, but Peterson says it won't be the last. He says they are
planning to convene every three years to continue driving new
research ideas.
I'll definitely attend again, and in honor of my Comic-Con
friend maybe I'll come dressed as General Sherman, the renowned
Giant Sequoia. You never know - the idea could catch on. But
maybe my fellow arborists would be happier if I just came with a
notebook full of research project ideas instead.
