Using Science to Improve the BLM Wild Horse and Burro Program: A Way Forward reviews the science that underpins the Bureau of Land Management's oversight of free-ranging horses and burros on federal public lands in the western United States, concluding that constructive changes could be implemented. The Wild Horse and Burro Program has not used scientifically rigorous methods to estimate the population sizes of horses and burros, to model the effects of management actions on the animals, or to assess the availability and use of forage on rangelands. Evidence suggests that horse populations are growing by 15 to 20 percent each year, a level that is unsustainable for maintaining healthy horse populations as well as healthy ecosystems. Promising fertility-control methods are available to help limit this population growth, however. In addition, science-based methods exist for improving population estimates, predicting the effects of management practices in order to maintain genetically diverse, healthy populations, and estimating the productivity of rangelands. Greater transparency in how science-based methods are used to inform management decisions may help increase public confidence in the Wild Horse and Burro Program.

National parks are different from other federal lands in the United States. Beginning in 1872 with the establishment of Yellowstone, they were largely set aside to preserve for future generations the most spectacular and inspirational features of the country, seeking the best representative examples of major ecosystems such as Yosemite, geologic forms such as the Grand Canyon, archaeological sites such as Mesa Verde, and scenes of human events such as Gettysburg. But one type of habitat--the desert--fell short of that goal in American eyes until travel writers and the Automobile Age began to change that perception. As the Park Service began to explore the better-known Mojave and Colorado deserts of southern California during the 1920s for a possible desert park, many agency leaders still carried the same negative image of arid lands shared by many Americans--that they are hostile and largely useless. But one wealthy woman--Minerva Hamilton Hoyt, from Pasadena--came forward, believing in the value of the desert, and convinced President Franklin D. Roosevelt to establish a national monument that would protect the unique and iconic Joshua trees and other desert flora and fauna. Thus was Joshua Tree National Monument officially established in 1936, with the area later expanded in 1994 when it became Joshua Tree National Park. Since 1936, the National Park Service and a growing cadre of environmentalists and recreationalists have fought to block ongoing proposals from miners, ranchers, private landowners, and real estate developers who historically have refused to accept the idea that any desert is suitable for anything other than their consumptive activities. To their dismay, Joshua Tree National Park, even with its often-conflicting land uses, is more popular today than ever, serving more than one million visitors per year who find the desert to be a place worthy of respect and preservation.

The new Equid Action Plan provides current knowledge on the biology, ecology and conservation status of wild zebras, asses, and horses. It specifies what information is lacking, and prioritizes needed conservation actions. The Action Plan also provides chapters on equid taxonomy, genetics, reproductive biology, and population dynamics. These chapters highlight unsolved issues of taxonomy and genetics. They also provide information and insight into the special demographic and genetic challenges of managing small populations. The chapter on disease provides a review of documented equine disease and epidemiology and focuses on priorities for equid conservation health. The final chapter deals with the importance of developing an assessment methodology that explicitly considers the role of equids in ecosystems and the ecological processes that are necessary for ecosystem viability. The approach of combining ecological field studies and ecosystem modeling should prove useful for the scientific management and conservation of wild equids worldwide. These chapters provide research and conservation practitioners with new information and paradigms.

Nestled between the Rocky Mountains to the west and the High Plains to the east, Denver, Colorado, is nicknamed the Mile High City because its official elevation is exactly one mile above sea level. Over the past ten years, it has also been one of the country's fastest-growing metropolitan areas. In Denver's early days, its geographic proximity to the mineral-rich mountains attracted miners, and gold and silver booms and busts played a large role in its economic success. Today, its central location—between the west and east coasts and between major cities of the Midwest—makes it a key node for the distribution of goods and services as well as an optimal site for federal agencies and telecommunications companies. In Metropolitan Denver, Andrew R. Goetz and E. Eric Boschmann show how the city evolved from its origins as a mining town into a cosmopolitan metropolis. They chart the foundations of Denver's recent economic development—from mining and agriculture to energy, defense, and technology—and examine the challenges engendered by a postwar population explosion that led to increasing income inequality and rapid growth in the number of Latino residents. Highlighting the risks and rewards of regional collaboration in municipal governance, Goetz and Boschmann recount public works projects such as the construction of the Denver International Airport and explore the smart growth movement that shifted development from postwar low-density, automobile-based, suburban and exurban sprawl to higher-density, mixed use, transit-oriented urban centers. Because of its proximity to the mountains and generally sunny weather, Denver has a reputation as a very active, outdoor-oriented city and a desirable place to live and work. Metropolitan Denver reveals the purposeful civic decisions made regarding tourism, downtown urban revitalization, and cultural-led economic development that make the city a destination.
