What is UFORE?

UFORE is a computer program used to analyze our urban forest by combing:

  • Field observations
  • Meteorological information
  • Pollution data

UFORE calculates our urban forest for:

  • Environmental effects
  • Values
  • Structures

The City of Edmonton used this model to determine how effective the urban forest is in:

  • Cleansing the air
  • Carbon storage
  • Reducing storm water run off

The Study

The study is completed ever 10 years, the next one in 2019.

June to September 2009

Field observations: Recorded on 300 circular plots (on public and private land within the City)

  • Plot size: 22.6 meters diameter
  • Location selection: Generated randomly using a Geographic Information System (GIS)

Trees and shrubs in the plot were recorded for:

  • Species
  • Height
  • Diameter (trees only)
  • Health
  • Canopy width (trees only)
  • Density

Also recorded was:

  • Amount and type of vegetation
  • Porosity of the surface area
  • Open space available for new tree planting

No trees or shrubs were removed or damaged in conducting the survey.

Gathered data creates a model that establishes:

  • Species composition
  • Diversity
  • Amount of carbon stored
  • Pollution removed by trees

Tree species composition will be used to identify the insect and disease potential in the city.

The amount of storm water runoff generated from impermeable surfaces (for example, paved areas, will also be determined).
