This study by the British Columbia Ministry of Forests and Range was conducted to determine the infestation and destruction of pine trees by the mountain pine beetle and the effect of short and mid-term timber supplies. The Ministry, in conjunction with the Canadian Forest Service, developed an infestation model using forest cover maps, aerial views, and stand level mortality information in order to predict the spread of infestation. This information was used to plot salvage harvesting while dead wood was still useable over the short term under the belief that forest stands would recover over the long term. Additional modeling was used to determine the best course of action to take in order to maintain an economically viable harvest and ensure the establishment of new stands. Potential economic impacts, such as the ability to use timber destroyed by the beetles and the dependence of local economies dependent on harvesting were considered with several mitigating actions identified such as alternative uses of wood, including bioenergy and alternative wood products. Other impacts were also considered for mitigation, including effects on hydrology, undergrowth, biodiversity of tree species, and wildlife. This article provides a good overview for the timber industry in consideration of strategic planning for sourcing and supply. From a process standpoint, it provides a model for future study that relies on cause-consequence modeling.
I am interested to hear more about the restoration of the forests and how the local economies would be impacted by these activities. In addition, are the issues presented occuring in other areas? If so, have the methods described been implemented in these areas?
