Book Description
Eighty-four percent of the upland bird species in present-day bird counts along the Missouri River were included in bird species lists 150 years ago. Eighty-three percent of upland bird species in the Slim Buttes area also occurred 80 to 120 years ago. Historical photographs show native woodlands were part of the presettlement landscape. Expansion of the ranges of blue jays, common grackles, and eastern phoebes in western South Dakota can be attributed to tree plantings, cultivation, and urbanization rather than expanded native woodlands.

Book Description
An illustrated review of the Northern Great Plains that blends natural history and human history “The most complete, in-depth look at Dakota ecosystems and their history. An absolutely fascinating read!”—Gabe Brown, author of Dirt to Soil W. Carter Johnson and Dennis H. Knight describe the natural and human histories of the Northern Great Plains in this comprehensive and handsomely illustrated book. Covering a vast period of time, they move from geological developments millions of years ago and the effects of glaciers to historical and ecological developments in recent centuries and the effects of agriculture. The book ends with a discussion of the future of this region, mediated by climate change, with recommendations on how to balance agriculture and other pressing needs in the twenty-first century. Johnson and Knight bring decades of experience to chapters on the major ecosystems of the Dakotas. Written for readers with varying backgrounds, and with discussions of the Prairie Pothole Region, the Missouri River, grasslands, woodlands, the Black Hills, and rivers, lakes, and wetlands, the book is unique and will become a long-lasting source of information. Readers will appreciate the plentiful photographs and other color illustrations.

Book Description
Vegetation at the Glacier Lakes Ecosystem Experiment Site, a 600 ha research site at 3200 to 3500 m elevation in the Snowy Range of southeastern Wyoming, was categorized and described from an intensive sampling of species abundances. A total of 304 vascular plant taxa were identified through collection and herbarium documentation. Plots with tree species were separated from those without tree species for ordination and classification analyses. Detrended correspondence analysis was used to order plots along major axes of composition variation, which are inferred moisture and topographic gradients. Cluster analysis was used to categorize plots based on composition similarity. The resulting groups were named according to species dominants. We identified and described in detail 4 meadow, 4 thicket or scrub, 3 krummholz, and 2 forest plant associations.
