Case study : market opportunities for commercially thinned small diameter Douglas-fir trees Aquino, Carlos


Small Diameter logs are a becoming a regular occurrence in the forests of Interior British Columbia. This disturbance is caused by a decrease of forest fires and an increase of trees competing for water and soil. Historical records show that forest fires, use to create more space for young trees to grow by burning vast amounts of forest undergrowth, thereby produce nutrients for the soil in the form of fertilizers and minerals. Moreover, rainstorms required to diminish forest fires, contributed to the soil absorbing moisture for trees. However, due to global warming, changes in land use and settlement patterns, vast hectares of forest land are being exposed to dry weather. This meteorological behaviour is spreading across the Pacific Northwest from Canada to the USA. Regarding the ecological environment, Mule Deer winter ranges, which cover approximately 275,000 hectares in the Cariboo Forest Region are being affected by the small diameter Douglas Fir logs. In the past, large diameter Douglas Fir trees provided cover and forage for mule deers. Therefore this case study will focus on marketing small diameter Douglas Fir logs in established market niches that require a value-added product.
