This chapter discusses the dynamics between grasses and shrub vegetation, focusing on the factors that lead to transitions between grassland and shrublands and the stabilizing feedbacks and reproductive processes which maintain them. It then discusses the dynamics at the grassland–oak savanna interface. The chapter examines the constraints over the recruitment of oaks into grassland settings, and then describes the ways in which oaks modify understory vegetation and productivity once they are established into grasslands.Less

Straddling temperate forests and grassland biomes and stretching along the coastline of two Great Lakes, Wisconsin contains tallgrass prairie and oak savanna, broadleaf and coniferous forests, wetlands, natural lakes, and rivers. But, like the rest of the world, the Badger State has been transformed by urbanization and sprawl, population growth, and land-use change. For decades, industry and environment have attempted to coexist in Wisconsin—and the dynamic tensions between economic progress and environmental protection make the state a fascinating microcosm for studying global environmental change. This book brings together scientists, naturalists, and policy experts to examine how human pressures on Wisconsin's changing lands, waters, and wildlife have redefined the state's ecology. Though the chapters here focus on just one state, the text draws conclusions about changes in temperate habitats that can be applied elsewhere, and offer insights into the future of the ecology, conservation, and sustainability of Wisconsin and beyond.Less

This chapter examines changes in southern Wisconsin forests. It reports large declines in native plant diversity since the Curtis surveys, greater invasions of exotics, and more homogenization. Forest fragmentation and deer clearly play roles here, but so do the changes set in motion 150 years ago when fire suppression allowed oak woodlands to replace oak savannas. As tree canopies close with succession, these oak woodlands are further displaced by maples and other, more shade-tolerant trees. Shadier understories that rarely burn exclude, in turn, the oak seedlings that could regenerate oak woodlands along with the sun-loving forest herbs that once thrived there.Less

This chapter examines the effects of grazing in California's grasslands, oak savanna understory vegetation, and associated herbaceous riparian areas, providing a brief history of grazing in California grasslands and examining the grazing effects on California grassland wildlife. It also describes the ways in which grazing by nondomestic large mammals such as elk differs from grazing by livestock.Less
