Oregon's logging sector is characterized by extensive subcontracting between wood commodity manufacturing firms and independent logging contractors. Why is this so? Considerable recent scholarship has examined the dynamics of flexible production systems, including regional contractor networks, as prominent aspects of late capitalism. Although useful, existing accounts of flexibility are inadequate to explain why logging in particular would be subject to contract production relations. A second literature emphasizes the "difference" of nature-centered sectors, particularly industrial agriculture. I argue that a similar logic applies to logging. That is, natural sources of unpredictable variation and extensive, inconstant geographies restrict the predictability and calculability of production, and the imposition of labor monitoring and discipline. Contracts are a strategy for firms to displace resulting risks and costs onto contractors, while at the same time inducing expert-based rationalization of production. Repeat contracting provides a means of capturing expert knowledge among reliable contractors with knowledge of the parent firm's lands and mills. This is a particularly appealing strategy for vertically and horizontally integrated firms with complex operational portfolios. However, though contracting is one flexibility strategy, Weyerhaeuser's Competitive Logging Program featuring restructured wage relations provides an alternate path to more flexible production, one that further illuminates some of the problems of nature-based production.Key words: production subcontracting, logging, nature, organized labor, flexible specialization "Bring me Some Whistle Punks…."In the state of Oregon, most logging is accomplished via the practice of subcontracting. This involves wood commodity manufacturing firms tendering contracts to quasi-independent logging contractors -referred to in the industry as "gyppos"-to secure logging services. Although some wood products mills continue to run their own logging crews (referred to in the industry as logging "sides"), subcontracting has increasingly become the dominant form of industrial relation linking the factory floor to the woods during the post-World War II period. Given that the industry is not otherwise characterized by the existence of contract production networks (reforestation notwithstanding), why is contract logging so prevalent?In this paper, I explore why many wood products firms undertake logging by means of relatively arms-length industrial relations. I explain the incentive to contract out and to pursue other alternatives to fixed hourly wage relations as strategies for achieving production flexibilities in response to the nature-centered character of production in the logging sector. Specifically, I argue that variability, risk and uncertainty associated with the "in situ" character of logging production -i.e. the intimate engagement of social and natural production -creates an incentive for firms to minimize their exposure to these risks and uncertain...
