摘要

Following are the objectives of this project: Collect pre-treatment data on all sites for soil carbon, plants, invertebrates, and birds; Conduct controlled experiments to test the effects of a fire-grazing model on species distribution patterns of both plant and animal taxa in southern Iowa; Quantify the response of native and invasive plants to fire and grazing, and how these responses are mediated by prior land use; Quantify the response of invertebrates and prairie-obligate butterflies to changes in vegetation structure and composition; Quantify the response of grassland birds to changes in vegetation structure and composition, and to changes in the invertebrate prey base; and Quantify the relationship between nesting success of grassland bird species and habitat conditions.
