The Arborists of Philadelphia Parks & Recreation’s Urban Forestry & Ecosystem Management divisions are charged with the care of the trees on 10,250 acres of park land, and the 117,000 trees along the city streets. These men and women are passionate, hardworking, and proud of the work they do to keep Philadelphia’s trees healthy and its citizens safe. For this project, photographer Sabina Louise Pierce worked with the TreePhilly program to capture the special relationship between Philadelphia Parks & Recreation arborists, the trees they care for, and the tools of their trade.
“When I was asked by TreePhilly
to shoot portraits
of Philadelphia’s Arborists as a freebie,
I said sure!
I love trees,
I love Philly.
Little did I know was how much the people
that worked with them loved them too.
Some have master’s degrees and all could
make more in the private sector
but they do this because they love trees too!”
Sabina Louise Pierce
Lover of trees and nature.
