Fig. 2. Land use–land cover proportions in the watersheds stratified by ecoregion and/or size that are discussed in this study. WP, Western High Plains and Tablelands; FH, Flint Hills; GP, Glaciated Plains; SH, Nebraska Sand Hills; WCB, Western Corn Belt Plains; CIP, Central Irregular Plains; OH, Ozark Highlands; CGP, Central Great Plains; MRL, Mississippi River Lowlands. The proportions for some do not add to precisely 100% in some cases because not all of the possible eight land use–land cover types are shown.
