Most prairies exist today as fragmented landscapes, making thoughtful and vigilant management ever more important. Intended for landowners and managers dedicated to understanding and nurturing their prairies as well as farmers, ranchers, conservationists, and all those with a strong interest in grasslands, ecologist Chris Helzer’s readable and practical manual educates prairie owners and managers about grassland ecology and gives them guidelines for keeping prairies diverse, vigorous, and viable.
Chapters in the first section, "Prairie Ecology," describe prairie plants and the communities they live in, the ways in which disturbance modifies plant communities, the animal and plant inhabitants that are key to prairie survival, and the importance of diversity within plant and animal communities. Chapters in the second section, "Prairie Management," explore the adaptive management process as well as guiding principles for designing management strategies, examples of successful management systems such as fire and grazing, guidance for dealing with birds and other species that have particular habitat requirements and with the invasive species that have become the most serious threat that prairie managers have to deal with, and general techniques for prairie restoration. Following the conclusion and a forward-thinking note on climate change, eight appendixes provide more information on grazing, prescribed fire, and invasive species as well as bibliographic notes, references, and national and state organizations with expertise in prairie management.
Grasslands can be found throughout much of North America, and the ideas and strategies in this book apply to most of them, particularly tallgrass and mixed-grass prairies in eastern North Dakota, eastern South Dakota, eastern Nebraska, eastern Kansas, eastern Oklahoma, northwestern Missouri, northern Illinois, northwestern Indiana, Iowa, southwestern Wisconsin, and southwestern Minnesota. By presenting all the factors that promote biological diversity and thus enhance prairie communities, then incorporating these factors into a set of clear-sighted management practices, The Ecology and Management of Prairies in the Central United States presents the tools necessary to ensure that grasslands are managed in the purposeful ways essential to the continued health and survival of prairie communities.
In the rush of modern life, we measure our lives by the clock, the calendar, the timetable. But there are older rhythms in nature: the call of chickadees before the first hint of spring, the golden face of a compass plant in July, the first snowfall. These signs mark the passage of time in a world that Aldo Leopold knew well and eloquently described.
With notebook and camera in hand, John and Beth Ross revisit the Aldo Leopold Memorial Reserve in south-central Wisconsin fifty years after Leopold’s death. Thanks to the efforts of Leopold, his family, and the Leopold Foundation, this once-ruined farmland is now largely restored to a natural state. The Rosses explore the terrain of this sandy land, encounter its natural citizens, and relate life here to its physical underpinnings. Following Leopold’s own practice of phenology, they note the seasonal changes: arrivals and departures of wild geese, the blossoming of the pasque flower at the edge of melting snow, the appearance of monarch butterflies on the milkweed. And further, they seek to find in this landscape an underlying morality, a communion of understanding, a sense of place in the cosmos.
Beautifully illustrated with color photographs, the book also includes notes on the behavior, habitat, and human interactions with ninety-four species of plants, birds, and other animals found in the reserve. An extensive glossary explains terms from geology, ecology, meteorology, and related life and earth sciences.
