What Is Urban Forestry?What Is Urban Forestry?
• Urban Forestry is a specialized segment of forestry.– Takes place in populated areas of cities.– Offers challenges in managing trees not
often found in forests.
• Air pollution, confined growing space, and compacted soils are some factors that can make the management of trees difficult.

• Healthy urban forests improve the quality of life by cleaning the air.
– They remove smog & pollutants from the air. This is important since we take 23,000 breaths in a day.
• Trees produce oxygen
– A half hectare of trees produces enough oxygen for 25 people.

• Trees serve as barriers– Trees can serve as windbreaks
• Very useful in winter months.
– Trees can block unsightly views• Blocks industrial highways or areas.
– Trees can lower sound pollution• Reduces noise near places of work.• Improves residential quality of life.

• Trees have a cooling effect on summer days.– Air temperature under a large shade tree
can be 15 degrees cooler than the temperature in the sun.
• A single large deciduous tree in leaf provides protection from UV rays.

• Trees are beautiful, and some have showy flowers, or attractive foliage.– Well-landscaped houses with mature trees
can be valued at 10 to 15% more than houses lacking trees.

• Although difficult to measure, trees have a positive affect on humans.– Research shows urban forests to be good
for mental health.
• Urban forests contribute to a healthy environment.– Reduces storm water run-off & soil
erosion, produces oxygen, and provides food/shelter for wildlife.

• Urban forests are managed with different uses in mind.
• In urban settings trees impact watersheds, wildlife, fish habitats, and wood production.
• Urban forestry programs address the need to educate the public on the role of trees in the environment.

• Urban forestry management programs have a variety of objectives:
– Inventorying trees as to species, size, age, and value.
– Care and Maintenance of trees• Includes pest and disease
management.
– Installation and Removal of trees• Urban forests are always changing
therefore the removal of trees due to death, decline or safety is necessary.

The General Goals for Community Forest Programs
1. Establish & maintain maximum tree cover.2. Maintain trees in a healthy condition
through good cultural practices.3. Establish and maintain an optimal level of
age & species diversity.4. Promote conservation of tree resources.5. Select, situate, and maintain street trees.6. Centralize tree management.7. Promote efficient management of urban
forestry.8. Foster community support for forestry.

• Municipalities often adopt tree ordinances to meet goals of attaining a healthy, vigorous, and well-managed community forest. – Provide authorization
& standards management activities.

the planting and removal of trees within public rights-of-way.– Often contain rules regarding private trees,
which pose a hazard to traveling public.– Planting requirements, like those in
parking lots, are generally outlined.
