STOPPING INVASIVE SPECIES STARTS
WITH RESEARCHING THEM
If someone
would let him,
Jim Zwack,
Director of
Technical Services within The Davey
Institute, could talk about Emerald
Ash Borer (EAB) for days.
Not just because he finds the
species interesting. (He does.) Not
only because EAB has killed 100+
million trees and spread across 17
states and Canada. (It has.) And not
merely because EAB impacts tree
biomechanics in a way that makes
affected trees extremely dangerous.
(It can.)
But mostly because Jim knows from
scientific research at The Davey
Institute that individual ash trees can
be protected with a very high rate of
success. And that, says Jim, is what
makes The Davey Institute's work in
invasive species so profound.
"Given the right circumstances," he
says, "any invasive species—not
just EAB—can repopulate and
outcompete native material, making
invasive species of all kinds very, very
difficult to control."
Using plant science research, the
teams at The Davey Institute evaluate
everything from invasive species
behavior to tree biomechanics to
product chemistries, just to obtain
scientifically meaningful results to the
benefit of trees and turf.
Here, Jim shares three types and examples of invasive
species often found in commercial landscapes.
The Davey Institute
houses a diagnostic
lab with R&D scientists
and experts in any
particular aspect of
horticulture. Regional
technical advisors train
our technicians and
serve as resources to
address the specific
needs of our clients.
The
Institute
helps multi-
national product
companies evaluate
their chemistries for
uses and applications in
the green industry.
The
Institute
engages in
survey work
to evaluate and
document Davey Tree
sustainability processes
for the company's
corporate social
responsibility efforts.
DITS (Davey Institute
of Trees Sciences)
is a 100-year-old
landmark training pro-
gram for future Davey
leaders that involves an
entire month of rigorous
coursework and
technical skills training.
