Abstract Catastrophic forest disturbances, such as wildfires, insect outbreaks, and hurricanes, have become more frequent in recent decades. Such disturbances can create supply disruptions in regional timber markets, with potentially significant short-run and long-run price effects. We review the time-series intervention models that have been used to analyze the impacts of forest disturbances. We apply the intervention models to investigate the market effects of the Biscuit Fire that burned nearly 500,000 acres (202,000 hectares) of forest land in southwest Oregon in 2002, thus creating an unexpected supply shock in the regional timber markets. Most of the burned area was located on federal lands. Although almost two billion board feet were available for harvesting by some estimates, the salvage logging on public lands after the Biscuit Fire amounted to 60 million board feet by the end of 2005. We use a univariate and reduced-form model to estimate the effect of the Biscuit Fire on regional Douglas-fir log markets. We find that the fire did not cause immediate price effects; however, we detect positive effects during the salvage logging period in some of the markets, whereas a negative long-run effect has persisted since the salvage logging period was completed.

Removal of fire-killed trees (i.e. post-fire or salvage logging) is often conducted in part to reduce woody fuel loads and mitigate potential reburn effects. Studies of post-salvage fuel dynamics have primarily used chronosequence or modelling approaches, with associated limitations; longitudinal studies tracking fuels over time have been rare. We resampled a network of post-fire plots, comprising a range of logging intensities, 10 years after the 2002 Biscuit Fire (Oregon, USA). For surface woody fuels, which started from large treatment differences immediately following logging (stepwise increases with harvest intensity), we found converging trends among treatments at 10 years, with convergence nearly complete for fine fuels but not for coarse fuels. Fire-killed snags for the dominant species (Pseudotsuga menziesii) decayed while standing at a statistically significant rate (single-exponential k = 0.011), similar to or only slightly slower than down wood, suggesting that not all snag biomass will reach the forest floor. Live vegetation (largely resprouting sclerophyllous vegetation) is beginning to dominate surface fuel mass and continuity (>100% cover) and likely moderates differences associated with woody fuels. Post-fire logging had little effect on live fuels or their change over time, suggesting high potential for stand-replacing early-seral fire regardless of post-fire harvest treatments.

Wildfires have increased in number and size in recent years, making post-fire forest management an increasingly important topic. Citizen–agency interactions, citizen trust, and citizen acceptance of management strategies are central to successful planning and decision-making in these settings. In this study, citizen opinions from the attentive public are evaluated in two locations near recent fires in Oregon: the 2003 Bear and Booth Complex Fires and the 2002 Biscuit Fire. Results suggest an agency’s commitment to long-term interactions with citizens influences citizen trust in the agencies and acceptance of post-fire management strategies. There is broad acceptance for several post-fire management strategies (i.e. erosion control, replanting, reseeding). However, acceptance is highly dependent on trustworthy relations. Further, results suggest it is not enough to simply offer opportunities for public engagement; citizens need to feel that these activities were meaningful opportunities to participate. Although results differed between locations, overall the majority of respondents did not agree with how the local Forest Service and Bureau of Land Management handled forest planning after recent fires. Findings from this research indicate that positive citizen–agency relations need to be long-term and developed well before a fire occurs if post-fire actions are to be supported by communities.

We present data from a study of early conifer regeneration and fuel loads after the 2002 Biscuit Fire, Oregon, USA, with and without postfire logging. Natural conifer regeneration was abundant after the high-severity fire. Postfire logging reduced median regeneration density by 71%, significantly increased downed woody fuels, and thus increased short-term fire risk. Additional reduction of fuels is necessary for effective mitigation of fire risk. Postfire logging can be counterproductive to the goals of forest regenration and fuel reduction.
