Assess students' ability to analyze empirical and modeling studies on riparian buffer restoration effectiveness for reducing nitrogen and phosphorus runoff in agricultural watersheds. Scope includes buffer design (width, vegetation, placement), hydrologic connectivity, nutrient removal mechanisms, monitoring and study designs (paired-watershed, BACI, load calculations, models), statistical interpretation of reduction metrics, common confounders, and implications for management and policy; students should interpret data, evaluate methodological quality, identify limitations, and propose improvements or alternative assessment approaches.
