As residents living in hazard-prone areas face on-going environmental threats, the actions they take to mitigate such risks are likely motivated by various factors. Whereas risk perception has been considered a key determinant of related behavioral responses, little is known about how risk mitigation actions influence subsequent perceived risk. In other words, do actions to prevent or mitigate risk reduce risk perception? This longitudinal study considers the dynamic relationships between risk perception and risk-mitigating behavior in the context of forest disturbance in north-central Colorado. Based on panel survey data collected in 2007 and 2018, the results provide a first look at changes in perceived forest risks as they relate to individual and community actions in response to an extensive mountain pine beetle outbreak. Analysis revealed that the perception of direct forest risks (forest fire and falling trees) increased, whereas indirect forest risk perception (concern on broader threats to local community) decreased across the two study phases. Higher individual or community activeness (level of actions) was associated with subsequent reductions in perceived forest fire risk, smaller increases in direct risk perception, and larger decreases in indirect risk perception. These findings contribute insights into the complex risk reappraisal process in forest hazard contexts, with direct implications for risk communication and management strategies. 

Purpose of Review Outbreaks of tree-killing bark beetles have reached unprecedented levels in conifer forests in the northern hemisphere and are expected to further intensify due to climate change. In parts of Europe, bark beetle outbreaks and efforts to manage them have even triggered social unrests and political instability. These events have increasingly challenged traditional responses to outbreaks, and highlight the need for a more comprehensive management framework. Recent Findings Several synthesis papers on different aspects of bark beetle ecology and management exist. However, our understanding of outbreak drivers and impacts, principles of ecosystem management, governance, and the role of climate change in the dynamics of ecological and social systems has rapidly advanced in recent years. These advances are suggesting a reconsideration of previous management strategies. Summary We synthesize the state of knowledge on drivers and impacts of bark beetle outbreaks in Europe and propose a comprehensive context-dependent framework for their management. We illustrate our ideas for two contrasting societal objectives that represent the end-members of a continuum of forest management goals: wood and biomass production and the conservation of biodiversity and natural processes. For production forests, we propose a management approach addressing economic, social, ecological, infrastructural, and legislative aspects of bark beetle disturbances. In conservation forests, where non-intervention is the default option, we elaborate under which circumstances an active intervention is necessary, and whether such an intervention is in conflict with the objective to conserve biodiversity. Our approach revises the current management response to bark beetles in Europe and promotes an interdisciplinary social-ecological approach to dealing with disturbances. 

Abstract Forest disturbances caused by insects, pathogens, and fire continue to increasingly occur within forests across the United States and around the world. Given the dynamic nature of these forest disturbances and the role played by local residents in risk management, it is valuable to explore how the human experience, attitudes, and behaviors associated with these ecological processes may evolve over time. In this paper, we assess temporal changes in local residents’ perceptions and actions in response to the mountain pine beetle outbreak that affected large swaths of forests in north central Colorado. Through analyses of secondary and household survey data from 2007 and 2018, we note significant changes in these aspects and identify factors consistently associated with individual and community activeness. The study contributes to knowledge of dynamic socioecological considerations of forest disturbances and improves understanding of how social sciences can help to identify opportunities and barriers to effective forest ecosystem management. 

Mountain Pine Beetle (MPB) outbreaks bear attributions at multiple scales, from the practices of local extractive industries to state and federal forest management to global climate change. Since 1996, an outbreak of MPB has swept across nearly 3.4 million acres in north central Colorado. The area affected is constituted by a heterogeneous group of communities, and provides an opportunity to examine how institutional forces pattern experiences of the natural world and emergent environmental narratives. This work examines the narratives of local community and regional organizations, along with interviews and household survey data to consider culturally situated experiences and framings of the outbreak. Tracing environmental narratives is part of understanding different environmental vulnerabilities, which is essential to developing management regimes that are inclusive and ultimately sustainable.
