Vickers Hot Springs is located near the rural Southern California town of Ojai, and local residents have long enjoyed soaking in the sulfuric pools. But as knowledge of the springs spread, the area saw increases in fights, traffic, burglaries, and drug use. In response, two residents purchased the land and committed to restore the property while allowing limited public access, subsequently generating a great deal of controversy within the community. Privatizing Vickers Hot Springs follows the archetypical lesson of Garrett Hardin's 1968 essay, “The Tragedy of the Commons.” Hardin stated that the problem for common-pool resources was that a finite amount of services are demanded by a potentially infinite number of users, who have little to gain by sacrificing for the common good. But Hardin's theory does not always apply. Many communities have come together to manage resources, often without government oversight. Thus, the question is not whether or not Hardin's theory is accurate, but rather “under what conditions it is correct and when it makes the wrong predictions.” Case studies provide nuance to the broad brushstrokes of a theory, and whether Hardin's parable is applicable depends on the particularities of the common property resource conflict. Employing the frameworks established by Hardin, Dietz et al., and Ostrom, this paper examines the management of Vickers Hot Springs within its broader social, ecological, and political context, asking whether the particular circumstances of this resource use conflict made privatization the most predictable outcome.

The management of common forest land as community forest in Nepal is in practice since 1978. Studies showing the linkages between community forestry and common property resource are scanty in the country. This article discusses characteristics of common property resources and the principles and practices of community forestry in Nepal which is an example of common property resource management between Government agencies and users (co-managers). Forest User Groups (FUGs ) are the institutions responsible to manage the common property.

Areas with dry climates have recently become more vulnerable to wildfires as the soil and air moisture have been changing because of greenhouse gasses in the atmosphere. Areas especially impacted are Australia, the Amazon, and western United States. The common factors at these locations are a dry environment and brush or forests fueling the fires once they start. As the climate continues to change, less moisture is present in the ground in these areas. This proliferates the susceptibility to wildfire. Prevention methods for inhibiting wildfires include reducing our carbon footprint, using care around campfires and other causes of wildfire, as well as routine thinning and removal of excess vegetation. The purpose of this study was to determine whether there is a link between Climate Change and the extraordinary magnitude, intensity, and frequency of recent wildfires. Although it is not possible to link all these wildfires directly and undeniably to Climate Change, the data examined clearly point to a strong possibility that such a link exists.

AbstractThe rapid decline of salmon over the last hundred years in the western United States has occurred to a large extent because of the way people have viewed salmon. In this paper, we briefly examine several views of salmon and offer another view, one based on enduring themes of Buddhist thought and practice. We examine the understanding of the interdependence and unity of all things as the common foundation of both Buddhism and ecology. Finally, we provide guidelines for applying this understanding to the conservation of salmon, as well the relationship of humans to 'nature' in general.

A model of the commercial fishery, incorporating the microeconomic decisions of individual vessel operation, is developed and employed to predict the consequences of various methods of regulation, including: (i) total catch quotas; (ii) vessel licenses; (iii) taxes on catch (or effort); (iv) allocated catch (or effort) quotas. Among the principal predictions of the analysis are: (a) total catch quotas do not improve the economic performance of an open-access fishery; (b) limited entry results in distortion of inputs unless every input is controlled; (c) taxes and allocated transferable catch quotas are theoretically equivalent to one another in terms of economic efficiency, and both are capable in principle of optimizing exploitation of the common-property fishery.Key words: economics, fishery regulation, management, quotas, licenses, taxes, fishermen's quotas, common-property resource

AbstractPrevious investigations using continuous video monitoring of greater sage-grouse Centrocercus urophasianus nests have unambiguously identified common ravens Corvus corax as an important egg predator within the western United States. The quantity of greater sage-grouse eggs an individual common raven consumes during the nesting period and the extent to which common ravens actively hunt greater sage-grouse nests are largely unknown. However, some evidence suggests that territorial breeding common ravens, rather than nonbreeding transients, are most likely responsible for nest depredations. We describe greater sage-grouse egg depredation observations obtained opportunistically from three common raven nests located in Idaho and Nevada where depredated greater sage-grouse eggs were found at or in the immediate vicinity of the nest site, including the caching of eggs in nearby rock crevices. We opportunistically monitored these nests by counting and removing depredated eggs and shell fragments from the nest sites during each visit to determine the extent to which the common raven pairs preyed on greater sage-grouse eggs. To our knowledge, our observations represent the first evidence that breeding, territorial pairs of common ravens cache greater sage-grouse eggs and are capable of depredating multiple greater sage-grouse nests.
