Conifer-feeding budworms in the genus Choristoneura are eruptive species that periodically defoliate conifer forests in North America, causing growth loss and, ultimately, tree mortality. These impacts create the need for management interventions. Emerging trends in forestry require a holistic approach that considers the implications of budworm management within an ecosystem context. To minimize the negative impacts of forest practices and preserve ecosystems in perpetuity, we now seek to develop forest-management systems that emulate natural disturbances such as budworm outbreaks. This approach requires a detailed understanding of the ecosystem processes that cause the rise and fall of budworm populations, and of the changes that disturbances bring about. In this paper we review the data needs and present a system to manage budworm populations within the framework of ecosystem management.
