EXPERTISE
SAVING LIVES WITH URBAN
TREE COVER
Dr. Satoshi Hirabayashi, environmental modeler for the
Davey Institute, co-authored a peer-reviewed paper titled,
"Modeling lives saved from extreme heat by urban tree
cover." The research, conducted over three years, focuses
on two important areas: how many lives can be saved and
lost due to temperature changes and how temperatures
can be reduced from tree canopy cover. The paper studied
Baltimore, Maryland's temperatures during warm seasons
compared to annual premature mortality from extreme heat.
The findings will be incorporated into i-Tree Landscape for
consumer use. This paper covers the first trial of research
on this topic, and a second paper will be published soon
that applies this research and i-Tree technology to 10 U.S.
cities. "The overall goal of the paper is to bridge the gap
between separate stories: how many people can die or
be saved because of temperature change, and how much
temperatures can be reduced or affected because of the
existence of trees," said Hirabayashi. "We need to
somehow change people's mindset towards trees."

TREE MOVED INDOORS
FOR GIE+ EXPO
A green ash tree 45 feet tall took up temporary
residency inside Louisville, Kentucky's Freedom Hall
for the GIE+Expo.
The tree served as a classroom of sorts, hosting the
Women's Tree Climbing Workshop during the three-day
conference. Davey employees Alex Julius, Emmett
Shutts and Matt Salvator oversaw the removal of the
tree from nearby Cave Hill Cemetery, from where it
was transported by truck to the hall and erected
inside the expo.
Herb Landmann, project manager, National Business
Development Team, said the indoor climbing tree
installation offers a unique opportunity to expose other
green industry professionals attending the expo
to arboriculture.
"Projects like this are important because we are able
to recycle a tree and use it to help educate other tree
care professionals," he said.
Davey oversaw installation of this green ash tree for climbing
instruction at the GIE+Expo in late October.
