The white-tailed deer is one of the most studied animals in North America, yet much of the available information has been derived in ecosystems different from the Black Hills. The Black Hills are unique in that the dominant species, ponderosa pine, has excellent regenerative abilities. This attribute, combined with timber management practices and fire suppression efforts in the last century, has allowed pine to expand at the expense of other plant communities. A critical first step in maintaining viable white-tailed deer populations in the Black Hills is identifying key winter ranges. Given that protein and energy are limiting in winter forages in this region, the emphasis of management on these ranges should be to enhance forage quality and quantity. Prescribed burning and timber harvest can be used to enhance the forage base. Grazing systems designed to remove livestock from these key winter ranges before late summer will provide a greater portion of the woody plants for deer use. Research needs focus on understanding how changes in Black Hills community patterns have influenced deer foraging strategies and habitat use, and on the need for ecologically based techniques to maintain consistent forage quality. Addressing these needs in an ecosystem framework will result in habitat for not only deer, but also for a multitude of other animal and plant species.

Many changessome discouraging, others hopefulhave occurred in the Rocky Mountain region since the first edition of this widely acclaimed book was published. Wildlife habitat has become more fragmented, once-abundant sage grouse are now scarce, and forest fires occur more frequently. At the same time, wolves have been successfully reintroduced, and new approaches to conservation have been adopted. For this updated and expanded Second Edition, the authors provide a highly readable synthesis of research undertaken in the past two decades and address two important questions: How can ecosystems be used so that future generations benefit from them as we have? How can we anticipate and adapt to climate changes while conserving biological diversity?
