4. ● ● ● ● ● ● ● ● ● ● ● Value of ecosystem services provided Ecological processes Number of affected people Tastes and preferences of affected population What Determines Ecosystem Service Value?

5. ● ● ● ● ● ● ● ● ● ● ● Example: Georgia’s Private Forests

6. ● ● ● ● ● ● ● ● ● ● ● We identified seven forest characteristics that describe this variation: Forest type Riparian status Rare species abundance Public land buffer Scenic visibility Development status Geographic region Per acre value of ecosystem service Ecological processes Number of affected people Tastes and preferences of affected population What Determines Ecosystem Service Value?
