This paper focuses on an unprecedented bark beetle epidemic in British Columbia, Canada. The epidemic has killed vast areas of forests, with significant impacts to ecosystems and timber-dependent communities. Explanations of this outbreak continue to overlook or underemphasize important actors and relationships. This paper offers a more detailed explanation of the actors and processes involved in the outbreak and associated responses. Political ecology was applied to guide this analysis, emphasizing both the ecological and social factors involved. Research methods entailed an extensive literature review and over seventy interviews with scientists, policy makers, land managers, and elected officials. Findings illustrate how the outbreak involved many actors, beyond bark beetles and trees, and resulted from complex interactions between ecological and social factors. This study also reveals how actors that prioritized short-term economic gains shaped the conditions that fostered the outbreak and continue to constrain responses. This study illustrates how applications of political ecology that give increased attention to ecology are necessary to fully understand the drivers of environmental change. [ABSTRACT FROM AUTHOR]

This paper describes the development and implementation of Cambium, an agent-based forest sector model for strategic analysis. This model is designed as a decision-support tool for assessing the effects that changes in product demand and resource inventories can have on the structure and economic viability of the forest sector. Cambium models aggregate product supply as an emergent property of individual companies’ production decisions and stand-level ecological processes. Modeling the forest-products sector as a group of interacting autonomous economic agents makes it possible to include production capacity dynamics and the potential for mill insolvencies as factors in analyzing the effects of market and forest inventory based disturbances. The utility of this model is tested by assessing the impacts of a market downturn in the US forest products market on forest industry structure and mountain pine beetle (Dendroctonus ponderosae Hopkins) salvage harvesting in British Columbia, Canada. Simulation results indicate a significant medium-term timber supply shortage; reduced stumpage revenues; intensive cost competition among primary wood-products manufacturers; and a large number of insolvencies in the panel, lumber, and pulp sectors.

In this paper, we investigate the impact of various socioeconomic conditions on the value of timber tenures in the province of British Columbia. Two timber tenure models were created, one for short-term timber sale licenses and the other for longer term forest licenses. The short-term model revealed that timber sales that were awarded according to a combination of employment, revenue, and manufacturing criteria yielded $8.63/m3 less revenue than timber sales awarded based on revenue alone. Similarly, the long-term model indicates that manufacturing and employment conditions significantly reduce the bid on forest licenses. In both instances, we suggest that such conditions distort the use of timber, labour, and capital. Therefore, we conclude that recent forest policy changes in the province that removed several of these conditions greatly improved economic efficiency. Nevertheless, distribution impacts are likely to be important because resource rents have potentially been redistributed away from rural communities to the provincial government.
