Ratio of performance indicators in watersheds with prairie strips (10% prairie strips and 90% row-crops) to performance indicators in watersheds without prairie strips (100% row-crops). Soil sediment data are from Helmers et al. (2012); phosphorus, nitrogen, and rainfall runoff data are from Zhou et al. (2014); crop data are unpublished; bird data are from MacDonald (2012); and plant data are from Hirsh et al. (2013). Data were collected during 2008-2012 from three replicate watersheds for each treatment.
