CLARK ET AL.: A MODEL OF URBAN
FOREST SUSTAINABILITY
"Urban trees and forests are
considered integral to the
sustainability of cities as a
whole. Yet, sustainable urban
forests are not born, they are
made. They do not arise at
random, but result from a
community-wide
commitment to their
creation and management.”

2 Community Surveys
368 responses
Responses were used to create TMP
goals and strategies
Most of the survey respondents (40%)
felt that the quality of the City’s trees
has declined over the last 10 years. This
presents an opportunity to invest more
into public tree maintenance, public
education, and community outreach
events to support urban forestry efforts.
