Simulation Scenarios

No	Description	Notes

1	Areas identified as noncropland (10,154 km²) were assumed as grassland for the land use type, prior to their conversion to cropland (baseline)	The 2008 and 2009 CDLs were combined; then the combined layers were overlaid with locations of cropland conversion from Lark et al. (2015, 2020) to identify areas where noncropland was converted to cropland. For scenario 1, which is the baseline, those identified noncropland was assumed as grassland.
2	Grassland (10,154 km²) from scenario 1 was converted to continuous corn
3	Grassland (10,154 km²) from scenario 1 was converted to corn/soybean rotation
4	Grassland (10,154 km²) from scenario 1 was converted to corn/wheat rotation
