Agricultural Riparian Buffers
Nitrogen Reduction from Buffers:
• Intercept surface runoff and subsurface leaching
• Vegetative uptake
• Microbial denitrification
PA Riparian Forest Buffer Initiative:• 95,000 additional acres by 2025

Forest Buffers NOT profitable• However provide greater nitrogen reduction
• Greater ecosystem services
Grass Filter Strips MAY be profitable• Potentially only in riparian areas unsuitable
for maize production
Conclusions
Nitrogen credit trading alone not sufficient PES.
Combining with other programs may increase incentive.
• Bundle Credits
• Conservation Reserve Enhancement Program (CREP)
Conclusions
• Additional sources of revenue• Non-Timber Forest Products
• Biomass
• Nitrogen Credit Supply Curves
Next Steps
