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

Riparian Buffer ScenariosScenario Schematic

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
