Street Tree Survey Completed
Volunteers
map health and
diversity of
plantings
Portland Parks & Recreation
Urban Forestry staff and more
than 1,300 volunteers have sur-
veyed and mapped nearly every
planted street tree in Portland --
almost 220,000 in all, covering
all 96 of the city’s neighborhoods.
The effort is key to help inform
how PP&R manages Portland’s
urban forest going forward.
The trees, which are planted
in the public rights-of-way, rath-
er than on private property, have
also been measured, identified,
and each one’s health rated as
part of the city’s first comprehen-
sive inventory of street trees.
Findings from the tree inven-
tory, which was completed in
September, will be presented at
the 2016 Tree Inventory Summit,
a free public event this Saturday,
A measurement is taken of a street tree planted in the public right-
of-way during an inventory of street trees in Portland.
Nov. 5, from 8:30 a.m. to 3:30
p.m. at the Mt. Scott Community
Center, 5530 S.E. 72nd Ave.

that the Urban Forestry staff and
our valued volunteers worked so
hard on the Street Tree Inventory.
Their work will help inform and
guide stewardship of this valu-
able public asset.”
Workers and volunteers spent
approximately 17,000 hours on
the project from 2010 through
September 2016. Reports for
individual neighborhoods are
already available on Urban For-
estry’s web page. Residents are
encouraged to check-out the in-
formation for their local street
trees.
Preliminary findings from the
survey have already been in-
fluencing the city’s tree-related
policies. For example, Portland
is vulnerable to significant tree
losses from pests and diseases as
a result of a very high count of
maple trees along city streets. Ur-
ban Forestry now requires prop-
erty owners to plant alternative
species when replacing and plant-
ing new street trees.
Also, given the low percentage
of evergreen trees being plant-
ed, Urban Forestry has increased
the number of evergreens on its
approved planting lists from a
handful to more than 20, and is
encouraging evergreen planting.
