Urban forests provide numerous benefits to society, and now these important benefits can be accurately
quantified.
U.S. Forest Service’s Urban Forests Effects Model (UFORE)
Urban Forest Effects and
Values

Designed to provide information to aid cities, counties, and urban forest managers with:
Management Planning Design Budget Decisions

What Does UFORE Assess?
Forest structure and health - aid in urban forest managementCarbon storage and sequestration - aid in carbon accounting & potential carbon creditsBuilding energy use effects - accounting for direct savings to property ownersAir pollution removal - aid in developing plans to improve air qualityPotential pest impacts - understand the risk of invasive pests

Urban Forest BenefitsTrees perform the following beneficial functions that
can be translated into economic values
Removal of air pollutantsozone (O3), carbon monoxide (CO), sulfur dioxide(SO2), nitrogen dioxide (NO2), and particulate matter less than 10 microns (PM10)
Decrease energy costsshading and cooling effects of trees
Carbon storage and sequestrationStormwater mitigationIncrease property value

Carbon Storage & Sequestration
Carbon Storage – Carbon currently held within tree tissues (roots, stems, and branches) from year to year
Carbon Sequestration – Estimate of carbon that is removed annually from the atmosphere by trees and soil to be later stored in tissue.

Northern Kentucky85 tons/year absorbed & 3,059 tons stored = $ 69,745*
Bellevue 5 tons/year absorbed & 137 tons stored = $ 2,275
Covington 30 tons/year absorbed & 906 tons stored = $ 20,657
Florence 12 tons/year absorbed & 338 tons stored = $ 7,706
Fort Thomas 20 tons/year absorbed & 1,113 tons stored = $ 25,376
Newport 18 tons/year absorbed & 565 tons stored = $ 12,882
