Craig Denton notes, “Water will be the primary political, social, and economic issue in the Intermountain West in the twenty-first century.” Urban Utah thirsts for the Great Salt Lake principal source, the Bear River. Plans abound to divert it for a rapidly growing Wasatch Front, as the last good option for future water. But is it? Who now uses the river and how? Who are its stakeholders? What does the Bear mean to them? What is left for further use? How do we measure the Bear's own interest, give it a voice in decisions? Craig Denton's documentary takes on these questions. He tells the story of the river and the people, of many sorts, with diverse purposes, who live and depend on it. Bear River begins in alpine snowfields, lakes, and creeks in the Uinta Mountains, flows north through Wyoming, loops south in Idaho, and enters the inland sea by way of the an environmentally critical bird refuge. Along the way it has many uses: habitat, farms, electricity, recreation, lawns and homes. Denton researches the natural and human history of the river, photographed it, interviewed many stakeholders, and tried to capture the river perspective. His photographs, printed as crisp duotones, carry us downstream, ultimately to big questions, begging to be answered soon, about what we should and can make of the Bear River.

A study of the spring and summer habitat preferences of blue grouse was conducted on the Bear River Range in northern Utah. The main objective was to determine the important factors associated with habitat selection by blue grouse during the breeding season. One hundred and two sampling areas, delimited by similarities in vegetation and topography, were thoroughly searched with a dog for blue grouse. Fifty-four bio logical and physical variables were measured for each sampling area. Chi-square tests performed on all variables showed 11 of the 54 variables to be significant at an alpha of 0.20. These 11 variables (listed below) were considered to be the important factors influencing habitat selection by blue grouse. (1) search area type (2) area exposure (3) elevation (4) percent forested (5) understory density (6) primary cover species (7) secondary cover species (8) percent cover maples (Acer grandidentatum) (9) percent cover mixed brush (10) percent cover sagebrush (Artemisia tridentata) (11) total acres The chi-square test only determined if a variable significantly effected habitat selection by blue grouse. To determine whether this effect was positive or negative, the percent occurrence of areas on which blue grouse were present, or absent, was determined. Results indicated that the most favorable blue grouse habitat was draws at 5,500 -6.499 feet elevation. This favorable habitat contained 1-10 percent cover by maples, or a higher percent of maple which provided a large amount of edge effect; the presence of mixed brush or sagebrush, a medium understory, and an area incline of 5-19 percent.

Cutthroat tells the full story of the genuine native trout of the American West. This new edition, thoroughly revised and updated after 20 years, synthesizes what is currently known about one of our most interesting and colorful fishes, includes much new information on its biology and ecology, asks how it has fared in the last century, and looks toward its future. In a passionate and accessibly written narrative, Patrick Trotter, fly fisher, environmental advocate, and science consultant, details the evolution, natural history, and conservation of each of the cutthroat's races and incorporates more personal reflections on the ecology and environmental history of the West's river ecosystems. The bibliography now includes what may be the most comprehensive and complete set of references available anywhere on the cutthroat trout. Written for anglers, nature lovers, environmentalists, and students, and featuring vibrant original illustrations by Joseph Tomelleri, this is an essential reference for anyone who wants to learn more about this remarkable, beautiful, and fragile western native.

A natural history and celebration of the famous bears and salmon of Brooks River. On the Alaska Peninsula, where exceptional landscapes are commonplace, a small river attracts attention far beyond its scale. Each year, from summer to early fall, brown bears and salmon gather at Brooks River to create one of North America’s greatest wildlife spectacles. As the salmon leap from the cascade, dozens of bears are there to catch them (with as many as forty-three bears sighted in a single day), and thousands of people come to watch in person or on the National Park Service’s popular Brooks Falls Bearcam. The Bears of Brooks Falls tells the story of this region and the bears that made it famous in three parts. The first forms an ecological history of the region, from its dormancy 30,000 years ago to the volcanic events that transformed it into the Valley of Ten Thousand Smokes. The central and longest section is a deep dive into the lives of the wildlife along the Brooks River, especially the bears and salmon. Readers will learn about the bears’ winter hibernation, mating season, hunting rituals, migration patterns, and their relationship with Alaska’s changing environment. Finally, the book explores the human impact, both positive and negative, on this special region and its wild population.
