Pine Beetle

The Mountain Pine Beetle epidemic in Alberta has been substantial, with several forest products companies facing a potential decrease in fibre supply as a result. Accurate forest inventory is integral in developing management strategies that effectively address the infestation. Within this context, forest inventory must provide enough species composition detail to allow the design of appropriate harvesting activities. The project evaluated the use of softcopy photo-interpretation and a semi-automated inventory approach to create a forest inventory with a higher level of detail, and looked to advance these methodologies to explore whether metrics such as tree height and volume could also be included. The project also aimed to demonstrate the benefits that such an inventory could provide in growth and yield analysis and within the general framework of integrated land management. Results indicate that the more detailed inventory is useful in addressing forest management challenges associated with the Mountain Pine Beetle infestation and in improving growth and yield analysis, resulting in an overall enhancement to strategic and operational planning. The inventory can also be used for integrated land management, allowing for species composition to be spatially identified within the stand and the identification of other features including anthropogenic disturbance and microsites.

Near Term

A number of near-term timber supply shocks are projected to impact global forest product markets, particularly mountain pine beetle induced timber reductions, a Russian log export tax, and timber supply increases from plantation forests in the Southern Hemisphere and Sweden. We examined their effect on a number of global jurisdictions using a dynamic global forest products trade model that separates British Columbia (BC) into coastal and interior forest sectors. The results suggest that global increases in plantation timber would have negligible effects on BC log and lumber markets, that the Russian tax would have minor effects on this market, and that the beetle-induced timber supply drop would moderately increase BC prices (primarily log prices). In the United States South, lumber and log prices could rise as a result of the mountain pine beetle, while other shocks will have a negligible impact on prices. Yet, lumber production will fall because log prices will increase substantially more than lumber prices. Japan could be impacted much more than other regions by the Russian tax on log exports. In the absence of export taxes, a beetle-induced timber shortage would cause lumber production in Japan to rise (as Japan can access nearby Russian logs), while the export tax would reduce lumber production because log prices rise disproportionately more than in other regions.

Salvage Harvesting

This paper describes the development and implementation of Cambium, an agent-based forest sector model for strategic analysis. This model is designed as a decision-support tool for assessing the effects that changes in product demand and resource inventories can have on the structure and economic viability of the forest sector. Cambium models aggregate product supply as an emergent property of individual companies’ production decisions and stand-level ecological processes. Modeling the forest-products sector as a group of interacting autonomous economic agents makes it possible to include production capacity dynamics and the potential for mill insolvencies as factors in analyzing the effects of market and forest inventory based disturbances. The utility of this model is tested by assessing the impacts of a market downturn in the US forest products market on forest industry structure and mountain pine beetle ( Dendroctonus ponderosae Hopkins) salvage harvesting in British Columbia, Canada. Simulation results indicate a significant medium-term timber supply shortage; reduced stumpage revenues; intensive cost competition among primary wood-products manufacturers; and a large number of insolvencies in the panel, lumber, and pulp sectors.

Mixed Species Forest

The management of public forestland is often carried out by private forest companies, in which case the landowner needs to exercise care in dealing with catastrophic natural disturbance. We use the mountain pine beetle ( Dendroctonus ponderosae Hopkins, 1902) damage in British Columbia to explore how the public resource owner can protect future timber supply while salvaging damaged stands. We examine the variability and timing of beetle attack in a mixed species forest using mathematical programming to schedule harvest but employ the novel strategy of maximizing the timber portfolio at the end of the 20 year time horizon rather than net present value. Various financial and even-flow constraints insure a modicum of stability during the salvage period. We also model supply of adequate feedstock for electricity generation. Based on our study, the optimal short-run response to beetle damage is to increase harvests in stands with 70% or more lodgepole pine ( Pinus contorta var. latifolia Engelm. ex S. Watson) that would otherwise be uneconomic to harvest, similar to operational practice reported by the BC government. The government could focus on stable supply of individual forest products over the time horizon, thereby also stabilizing short-term revenues. Alternatively, it could emphasize an even-flow of total harvest to greatly enhance revenues (which also exhibit greater volatility) and rely more heavily on future harvests of damaged timber. Regardless of the strategy chosen, optimizing future timber supply potential means that a large proportion (about 25% in this study) of damaged pine is left for future harvest, although it will not be of sufficient quality to produce lumber.
