3 Forecasted change in the proportion of counties in forest land use for (“Southern forest resource assessment”) Forecasted change in the proportion of counties in urban land use for Providence Canyon, GA

4 Consequences of Land Use/Cover Changes Land Use Geomorphology Hydrology Chemistry Resources Increased temperature Decreased dissolved oxygen Increased nutrients Burial/loss of substrate Increased tolerant species Decreased sensitive species Decreased species richness

5 Sediment: 2-5x increase  Nitrate (NO3): 2-7x increase  Phosphorus: 1-9x increase  Fecal coliform: 4-10x increase  E. coli: 6x increase  Pesticides – present in 1/3 of urban streams (Weston et al. 2011)  Pharmaceuticals – present in 80-90% of urban streams (Kolpin et al. 2008) Sewer discharge - Coosa River Increases in % impervious surface within watershed are linked to increased concentrations of: Fish Health - Urban Site
