Abstract

This study examined nutrient, water and carbon cycling processes and biodiversity patterns within replicated sub-watersheds that comprised different configurations of annual and perennial plant communities, ranging from conventional row crops to mixed annual and perennial systems to reconstructed native plant communities.

Key Question

How much perennial plant cover is needed to achieve significant improvements in water quality?

Findings

Results suggest that placing as little as 10 percent perennial cover in the lower (toe) portion of a watershed can substantially reduce sediment loss by greater than 90 percent.
