The Central Grassland region covers a large proportion of the contiguous U.S., and has experienced dramatic alterations through human landuse management. These changes in landuse management have caused significant changes in ecosystem attributes that are important to regional dynamics and sustainability, including plant community structure, net primary productivity, carbon storage, trace gas flux, and atmosphere-biosphere interactions that determine regional climate. Although previous studies have evaluated the effects of landuse at subregional scales (county to state levels), no previous work has assessed all of these factors as an integrated assessment of the impacts of landuse management at the scale of the entire central grassland region and at a resolution that will allow for the important effects of heterogeneity in landuse and soil type to be expressed. This study represents the first integrated regional assessment of landuse for the central grasslands, utilizing a suite of databases, remote sensing, and simulation models. The research will provide estimates of the impact of landuse on regional ecosystem attributes including plant species composition, above-and below ground net primary productivity, trace gas flux, and total system carbon storage.
