To avoid extinctions and other harms to ecological health from escalating climatic change, scientists, resource managers, and activists are considering and even engaging in "assisted migration" -- the intentional movement of an organism to an area in which its species has never existed. This article explores the profound implications of climate change for American natural resource management through the lens of this controversial adaptation strategy. It details arguments regarding the scientific viability and legality of assisted migration under the thicket of laws that govern natural resources in the US. The article explains why contemporary natural resource law's fidelity to historic baselines, protecting preexisting biota, and shielding nature from human activity is increasingly unte...

The U.S. Fish and Wildlife Service (Service) proposes to revise the designated critical habitat for the northern spotted owl (Strix occidentalis caurina) under the Endangered Species Act of 1973, as amended (Act). Consistent with the best scientific data available, the standards of the Act, our regulations, and agency practice, we have initially identified, for public comment, approximately 13,962,449 acres (ac) (5,649,660 hectares (ha)) in 11 units and 63 subunits in California, Oregon, and Washington that meet the definition of critical habitat. In addition, however, the Act provides the Secretary with the discretion to exclude certain areas from the final designation after taking into consideration economic impacts, impacts on national security, and any other relevant impacts of spec...

We have sought in the present paper to emphasize the role of cities in the globalisation of the economy, the expanding presence of cities in global networks, and the dynamics of urban systems. Ducruet and Lee present a typology of port-urban relations and then propose a means of transcribing every type into simple quantitative expressions. On Scott and Storper's reading, cities and regions are critical foundations of the development process as a whole. Rozenblat and Pumain examine how a specific kind of inter-urban connection is created through the location process of multinational firms in European cities. Sassen points out that the rise of cities as strategic economic spaces is the consequence of the urbanizing of a growing range of economic activities.
