Landcover change is an important global change process with diverse direct and indirect causes and consequences within social-ecological systems. Although substantial uncertainties exist regarding the future of landcover change and its affects, the consideration of past, present, and potential future changes could be useful for learning, assessing, adjusting, and preparing.
I consider case studies of past, present, and future landcover and landcover change in selected landscapes of Nebraska, U.S.A. Specifically, I present species distribution model ensembles for 16 tree species in the Missouri River bluffs of extreme southeast Nebraska, assess functional connectivity of wetland habitats in three central Nebraska landscapes that have experienced varying degrees of human-driven landcover change over the past several centuries, and develop scenario storylines and simulations of future landcover change for the Pine Ridge of extreme northwest Nebraska. Results are useful for increasing understanding about regional landcover changes and for informing ongoing conservation activities.

Agriculture is an economically important form of landuse in the North American Great Plains. Since 19th Century European settlement, conversion of grasslands to rowcrops has increased food and bioenergy production, but has decreased wildlife habitat. Future agricultural landuse changes may be driven by alternative energy demands and regional climatic changes. Landuse change and its drivers could affect bioenergy production, wildlife populations and natural resources, and considering the potential impacts of impending changes in advance could assist with preparations for an uncertain future.
This study addressed how the conversion of marginally productive agricultural lands in the Rainwater Basin region of south-central Nebraska, U.S.A. to bioenergy switchgrass (Panicum virgatum) might impact ethanol production, grassland bird populations and agricultural groundwater withdrawals. This study also used multi-model inference to develop predictive models explaining annual variation in springtime wetland occurrence and flooded area in the Rainwater Basin.
Results suggest that cellulosic ethanol production from switchgrass and residual maize (Zea mays) stover within existing starch-based ethanol plant service areas is feasible at current feedstock yields, removal rates and bioconversion efficiencies. Throughout the Rainwater Basin, the replacement of marginally productive rowcrop fields with switchgrass could increase ethanol production, conserve groundwater and benefit grassland birds under novel future climatic conditions. However, converting Conservation Reserve Program (CRP) grasslands to switchgrass could be detrimental to grassland bird populations. Predictive wetland inundation models suggest that surrounding agricultural landuse, wetland hydric footprint shape complexity, and autumn and winter precipitation and temperature are strong drivers of springtime wetland occurrence and flooded area in the Rainwater Basin.
