Charlotte’s Trees as Green Infrastructure

• City of Charlotte views public trees as green infrastructure
• There’s work to do
• View needs to be developed and better integrated into

City’s management strategies

• 50% tree canopy coverage of entire City of Charlotte by

2050…………aka “50 by 50”

• We know trees aren’t the answer to every problem, but one
• f the tools to help move the needle

Value of Trees in Charlotte

– 3% decline in canopy over 7 years

Urban Forestry Master Plan

Community-Driven Urban Forestry Management Plan

• A high level playbook targeting all stakeholders and all areas public

and private

A Master Plan Is Created by All Stakeholders

• Promotes awareness of the urban forest resource.
• Fully describes the community’s urban forest goals.
• Creates a plan to reach the community’s goals and

defines responsibilities: “a playbook”.

• Embeds success measures into the plan.

Urban Forestry Master Plan

• Holistic planning for the future
• Need to get beyond the basic “Trees are Good!” mindset
• Of course they’re good, but WHY?

– Benefits – environmental, social and economic

• Ok…..now we’re going to monitor the WHY…….get

data……and refine goals, strategies, development requirements, etc.

• Tools used:

– UFMP, i-Tree, GIS, partnerships, new research, feedback from professionals/community, collaborate with in-house professionals

Partnerships

• The City of Charlotte’s greatest impact with trees

is on public property….that won’t cut it…….need partners

• Mecklenburg County
• Catawba Lands Conservancy
• City of Charlotte – all departments especially

Storm Water Services

• Researchers
• TreesCharlotte
• Charlotte Community

TreesCharlotte Collaborative
