The Economic and Environmental Benefits of Urban Trees
UFORE is a computer model developed by the U.S. Forest Service to calculate the structure, environmental effects and values of urban forests. It has been used extensively in various places in the U.S. and abroad. Using land cover maps and field survey inputs, the model provides accurate estimates of urban forest effects based on credible scientific research and analysis. UFORE provides estimates of:
- Urban forest structure by land over type. Data variables include species composition, number of trees, diameter, tree density, tree health, leaf area, and biomass of leaves and trees.
- Hourly amounts of pollution removed by the urban forest. Pollution removal is calculated for ozone, sulfur dioxide, nitrogen dioxide, carbon monoxide and particulate matter 10 microns or smaller.
- Hour urban forest volatile organic compound emissions and the relative impact of tree species on net ozone and carbon monoxide formation throughout the year.
- Total carbon stored and net carbon annually sequestered.
- Effects on building energy use and consequent effects on carbon dioxide emissions from power plants.
- Replacement value of the forest, as well as the dollar value of air pollution removal and carbon storage/sequestration.
