Conservation and restoration programs usually involve nostalgic claims about the past, along with calls to return to that past or recapture some aspect of it. Knowledge of history is essential for such programs, but the use of history is fraught with challenges. This essay examines the emergence, development, and use of the “ecological baseline” concept for three levels of biological organization. We argue that the baseline concept is problematic for establishing restoration targets. Yet historical knowledge—more broadly conceived to include both (...) social and ecological processes—will remain essential for conservation and restoration. (shrink)

In 1937 Joseph Grinnell founded the University of California’s first biological field station, the Hastings Natural History Reservation. Hastings became a center for field biology on the West Coast, and by 1960 it was serving as a model for the creation of additional U.C. reserves. Today, the U.C. Natural Reserve System is the largest and most diverse network of university-based biological field stations in the world, with 36 sites covering more than 135,000 acres. This essay examines the founding of the (...) Hastings Reservation, and asks how it managed to grow and develop, in the 1940s and 1950s, during a time of declining support for natural history research. It shows how faculty and staff courted the support of key institutional allies, presented themselves as the guardians of a venerable tradition in nature study, and emphasized the station’s capacity to document ecological change and inform environmental policy and management. In the years since, Hastings and other U.C. reserves have played crucial roles in California environmental politics. Biological field stations in the post-war era deserve more attention not only from historians of biology, but also from environmental historians and other scholars interested in the role of science in society.

Leave No Trace (LNT) has become the official education and outreach policy for managing recreational use in parks and wilderness areas throughout the United States. It is based on seven core principles that seek to minimize impacts from backcountry recreational activities such as hiking, climbing, and camping. In this paper, we review the history and current practice of Leave No Trace in the United States, including its complex role in the global political economy of outdoor recreation. We conclude by suggesting (...) a new framework for building on the successes of Leave No Trace, while moving beyond its self-imposed limitations, and recapturing wilderness recreation as a more collaborative, participatory, productive, democratic, and radical form of political action.

In the early 20th century, after hundreds of years of gradual decline, the California condor emerged as an object of intensive scientific study, an important conservation target, and a cultural icon of the American wilderness preservation movement. Early condor researchers generally believed that the species' survival depended upon the preservation of its wilderness habitat. However, beginning in the 1970s, a new generation of scientists argued that no amount of wilderness could prevent the condor's decline and that only intensive scientific management (...) - including captive breeding - could save the species from certain extinction. A bitter and highly politicized battle soon developed over how to best preserve the condor. For 5 years the condor was extinct in the wild; however, by the time that officials released the first captive-bred birds the condor recovery program had garnered widespread public support, even among its former critics. Today, condor advocates from the scientific and activist communities work together to manage the species and protect its habitat. The condor's story illustrates some of the tensions, problems, and successes that have accompanied the rise of conservation biology as a scientific field and environmental movement in the United States.

Hastings became a center for field biology on the West Coast, and by 1960 it was serving as a model for the creation of additional U.C. reserves. Today, the U.C.
