Wide Rivers Crossed
Author: Ellen E. Wohl
Publisher: University Press of Colorado
ISBN: 1607322315
Category : Nature
Languages : en
Pages : 353
Book Description
In Wide Rivers Crossed, Ellen Wohl tells the stories of two rivers—the South Platte on the western plains and the Illinois on the eastern—to represent the environmental history and historical transformation of major rivers across the American prairie. Wohl begins with the rivers’ natural histories, including their geologic history, physical characteristics, ecological communities, and earliest human impacts, and follows a downstream and historical progression from the use of the rivers’ resources by European immigrants through increasing population density of the twentieth century to the present day. During the past two centuries, these rivers changed dramatically, mostly due to human interaction. Crops replaced native vegetation; excess snowmelt and rainfall carried fertilizers and pesticides into streams; and levees, dams, and drainage altered distribution. These changes cascaded through networks, starting in small headwater tributaries, and reduced the ability of rivers to supply the clean water, fertile soil, and natural habitats they had provided for centuries. Understanding how these rivers, and rivers in general, function and how these functions have been altered over time will allow us to find innovative approaches to restoring river ecosystems. The environmental changes in the South Platte and the Illinois reflect the relentless efforts by humans to control the distribution of water: to enhance surface water in the arid western prairie and to limit the spread of floods and drain the wetlands along the rivers in the water-abundant east. Wide Rivers Crossed looks at these historical changes and discusses opportunities for much-needed protection and restoration for the future.

Water-resources Investigations Report
An Atlas of Illinois Fishes
Author: Brian A. Metzke
Publisher: University of Illinois Press
ISBN: 0252053087
Category : Nature
Languages : en
Pages : 312
Book Description
Lake Michigan, winding creeks, sprawling swamps, and one of the world’s great rivers--Illinois’s variety of aquatic habitats makes the Prairie State home to a diverse array of fishes. The first book of its kind in over forty years, An Atlas of Illinois Fishes is a combination of nature guide and natural history. It provides readers with an authoritative resource based on the extensive biological data collected by scientists since the mid-1850s. Each of the entries on Illinois’s 217 current and extirpated fish species offers one or more color photographs; maps depicting distributions at three time periods; descriptions of identifying features; notes on habitat preference; and comments on distribution. In addition, the authors provide a pictorial key for identifying Illinois fishes. Scientifically up-to-date and illustrated with over 240 color photos, An Atlas of Illinois Fishes is a benchmark in the study of Illinois’s ever-changing fish communities and the habitats that support them.
