Pine Beetle Has Killed Half of British Columbia's Pine Trees. By Holly Pytila, IPS, March 12, 2009."'The pine beetle kill,' as it's known to British Columbians, refers to the millions of hectares of trees left for dead in the wake of the voracious insect. Forestry officials in Canada's westernmost province estimate the volume of wood lost to be around 620 million cubic meters - roughly equivalent to 15 million logging truck loads. According to a B.C. Ministry of Forests report, roughly half of the province's pine trees are now destroyed by the bug, with the most extensive damage occurring in the central Canadian Rockies, where two-thirds of the region's lodgepole pine forests have been transformed into a sea of orange needles. The beetle's environmental impact is just as impressive, as the death of billions of trees normally involved in capturing carbon have instead released carbon. Canadian Forest Service scientist Werner Kurz estimates the beetle's devastation will release almost a billion megatons of greenhouse gases into the atmosphere by 2020, equivalent to about five years of transportation sector emissions from Canada."
