Ecology And Management Of Black Bears In Yosemite National Park

As majestic as they are dangerous, and as timeless as they are current, bears continue to captivate readers. Speaking of Bears is not your average collection of stories. Rather it is the history, compiled from interviews with over 100 individuals, of how Yosemite, Sequoia, and Kings Canyon National Parks, all in California’s Sierra Nevada, created a human-bear problem so bad that there were eventually over 2,000 incidents in a single year. It then describes the pivotal moments during which park employees used trial-and-error, conducted research, invented devices, collaborated with other parks, and found funding to get the crisis back under control. Speaking of Bears is for bear lovers, national park buffs, historians, wildlife managers, biologists, policy and grant-makers, and anyone who wants to know the who, what, where, when, and why of what once was a serious human-bear problem, and the path these parks took to correct it. Although these Sierran parks had some of the worst black bear problems in the country, hosted much of the research, and invented the bulk of the technological solutions, they were not the only ones. For that reason, intertwining stories from several other parks including Yellowstone, the Great Smoky Mountains, and Banff-Canada are included. For anyone seeking solutions to human-wildlife conflicts throughout the world, the lessons-learned are invaluable and widely applicable.

Since its introduction in 1979, CHEAPO, a computer based economic analysis program, has allowed users of the Stand Prognosis Model to evaluate silvicultural alternatives from an economic point of view. Subsequent modifications to the Prognosis Model have rendered CHEAP0 obsolete. This users guide covers a new computer model, CHEAP0 II, which is compatible with version 5.1 of the Prognosis Model and expands its economic analysis capabilities.
