Urban Forestry for Municipalities
Trees are a vital part of all cities and towns. Whether on public or private land, trees provide many benefits to a community including:
- aesthetic contributions,
- improved environmental quality and
- increased property values.
For all of these reasons, many municipalities look to trees as a way to make life better in their city or town.
In Connecticut, with the exception of trees in wetlands, trees on private property are usually not subject to the direct jurisdiction of the municipality. At the same time, trees in municipally-owned public spaces, such as along roads, in parks or adjacent to public schools, usually are the responsibility of the municipality. These public trees place financial and legal obligations on the community as a whole. These trees need to be cared for, with management costs involved and the need for plans and policies to guide their care.
These obligations are what form the basis of municipal urban forestry.
State Laws Relating to Municipalities and the Urban Forest
CGS Sec. 7-131
: Municipal ForestsGives municipalities authority to establish municipal forests and a municipal forest commission.
CGS Sec. 7-131a

Sets out requirements regarding the appointment of a tree warden.
CGS Sec. 23-59

Establishes that tree wardens must be qualified for the position and how that qualification may occur.
CGS Sec 23-65
: Processes Relating to Roadside TreesOutlines various aspects relating to the management of roadside trees by municipalities, such as the need for a permit for anyone seeking to remove a municipal tree and the penalties associated with damage or unauthorized removal of a municipal tree.
Plans, Goals, Policies and Ordinances
State law requires that each municipality appoint a qualified tree warden
. Many municipalities further define their urban forestry program through planning, the development of goals, the creation of policies and the establishment of ordinances.
Planning can come in different forms, depending on the interest of the group creating the plan. This can be illustrated by the different approaches taken regarding urban forestry planning by two major national professional organizations.
- The American Planning Association (APA) has published a document entitled Planning the Urban Forest: Ecology, Economy, and Community Development. This document discusses how urban forestry can be integrated into larger scale community planning. Urban forestry is considered in terms of integration with other community goals, such as economic growth and environmental issues. The various partners who might work together are identified along with how they might collaborate towards common goals.
An example of this type of plan is Bridgeport's BGreen 2020 Sustainability Plan. The plan describes urban forestry as a tool for accomplishing wider environmental and sustainability goals for the City.
- The American Public Works Association (AWPA) has produced a series of guidebooks for public works managers that look at urban forestry in terms of a series of Best Management Practices (BMP). One example of a BMP is the development of an Urban Forest Management Plan. This guidebook focuses on such specific outcomes as tree inventories, tree risk reduction and urban forest cost/benefit analyses, and what these mean to managers.
The Public Works Primer
, published by DEEP, combines aspects of both approaches. This document was produced in 2008 and although parts of it are dated, it still provides a very useful outline for municipalities.
In most cases, urban forestry goals set by municipalities are based on a quantitative standard. Examples of such number-based goals include:
- increased percentage of urban forestry canopy cover,
- reduced numbers of unhealthy or unsafe trees,
- increased diversity within the tree population, or
- more tree plantings in sections of town with proportionally less tree cover.
In each case, these goals depend upon there being some type of quantitative assessment of the urban forest at the start.
Street tree inventories
are useful in determining the basic status of the municipal urban forest. An inventory would include the number of trees, kinds of trees, condition of these trees and, in the case of a complete inventory, location of these trees within the municipality.
Alternatively, aerial photography can be used to provide detailed information regarding the extent of urban forest canopy cover
for a municipality. Urban tree canopy cover assessments are very useful for setting canopy cover goals and for allowing comparisons among different geographic areas within the municipality, such as among neighborhoods.
Examples of urban tree canopy cover assessments in Connecticut include those done for
The tools within the i-Tree software suite
are very useful tools for goal setting within a community. In particular, i-Tree Streets
and i-Tree Eco
can be used to provide extensive analyses of the urban forest based on collected data.
allows the user to summarize tree data for geographic areas at a variety of scales, develop information of the ecosystem services provided by those trees and relate those benefits to the demographic characteristics within those areas.
Policies and Ordinances:
Once a community has determined, through planning and goal-setting, what it would like to achieve, policies and ordinances are useful for keeping actions aligned with goals.
Written policies can be beneficial for guiding local decision-making, especially at the day-to-day level. For example, departmental policies can be created that apply to specific urban forestry activities such as the purchase of trees. They can also be established so that they apply only to the actions of that department.
are local, legislative acts. Ordinances usually have a degree of permanency and are established so that they are generally applicable to all parties, unless specific exemptions are included in the ordinance.
