0000046924 00000 n Because the task is enormous, the park’s priorities for mitigation of the effects of beetles are focused on removing hazard trees and hazard fuels tied to the protection of life and property. Mountain pine beetle typically initi-ates attacks on the lower 15 feet of a tree bole, although the crown of large trees, particularly sugar pine, may be attacked Figure 1. From biology to modelling and beyond, each scientist is helping to build a big-picture understanding of this beetle. 0000046377 00000 n Through winter, the Information Office is open 8:00 am–4:30 pm Mon–Fri. 0000046403 00000 n by sasha bell and India Groundwater. Wildfire prevention efforts, mountain pine beetle damage as well as some construction and road work mean thousands of trees are being cut down around Jasper, Alta. MPB primarily develop in pines such as lodgepole, ponderosa, Scotch and limber pines, and less commonly affect bristlecone and piñon pines. These small cylindrical beetles colonize and kill mature pine trees by boring through the bark and mining the layer between the bark and the wood of the tree. Take these steps to prevent pine beetle infestation in your trees and minimize risks to the forest. The mountain pine beetle is native to northern B.C. It is also present in an isolated population of pine that is surrounded by prairie in the Cypress Hills area of southwestern Saskatchewan, which was likely infested in the early 1980s. The mountain pine beetle, Dendroctonus ponderosae Hopkins (Coleoptera: Curculionidae: Scolytinae), is a major pest of pine forests throughout western North America ( Safranyik and Carroll 2006). (10) To protect ourselves and our forests, humans have kept natural forest fires under control. Now, Alberta is hoping to make headway in its fight against the beetle with the federal government’s October announcement of $68.4 million over three years to help control, research and mitigate the impacts of the damaging pest. 0000003749 00000 n They are important for shade, visual screening, cultural significance, and outstanding visual quality. 0000008577 00000 n Beetle affected forest in northern Alberta – Photo Credit: Government of Alberta . In its wake, it leaves dead forests, an increased risk of fire, and mill closures in forest communities. This translates to more than a decade of lumber supplies lost to BC, Canada’s largest exporter of timber to the U.S. housing market. These small cylindrical insects attack and kill mature trees by boring through the bark and mining the phloem - the layer between the bark and wood of the tree. Mountain pine beetle has ravaged immense areas of western Canada, having affected approximately 16 million hectares of forest throughout the region, dramatically changing the landscape and ecology. Introduction By Sasha Bell. Where mountain pine beetle populations are beyond control, or an outbreak has collapsed, there is a need to schedule harvesting to maximize value-recovery of dead timber and to assess the long term impacts on annual allowable cuts (AAC) and other resource values. The mountain pine beetle presently occupies a fraction of the range of all pine in North America, but this is changing rapidly. a large beetle outbreak in such a vast area as the park's backcountry, which comprises about 95 percent of the park. 0000048798 00000 n Parks Canada is moving forward with activities to address the impact of the mountain pine beetle in the Rocky Mountain national parks in Alberta and British Columbia.. Several projects are set to take place this winter in Jasper National Park, where the impacts of this native insect are most significant, as well as in Banff, Yoho and Kootenay national parks. Related to general climate warming, average winter temperatures in the Rocky Mountains have been higher than normal over the past ten years. Pine trees produce a thick resin (top image) which thwarts pine beetle infestation. Native to western North American forests, this small beetle has reduced the growth of millions of trees and caused widespread mortality to commercial tree species. 0000003638 00000 n The research also showed that jack pine, a more recent victim of the mountain pine beetle (attacks began in 2007), was found to have low amounts of the chemicals that ensured survival of the lodgepole, but more of the beneficial compounds that attract the beetles to the tree. �d�"���Bc#P����]�WrI(��� As hazard trees are removed, material is consolidated for utilization in park trails or construction projects. Its entire life cycle is spent beneath the bark of host trees, except when adults emerge from brood trees and fly in search of new host trees. The mountain pine beetle (Dendroctonus ponderosae) is a native insect that has coevolved as an important ecological component of western forests. There is a symbiotic relationship between the two organisms. When conditions are favourable, mountain pine beetle populations can increase to sizeable numbers. From 2000 to 2015, BC authorities estimate that the mountain pine beetles had decimated a total of 730 million cubic meters of pine trees. Mountain pine beetle is a dynamic ecological process that has both large scale ecological benefits within the park and the potential for large scale economic impacts on industrial forests. One priority is to mitigate hazard tree threats in or near high use areas such as road corridors, campgrounds, parking lots, housing areas and visitor centers. Mountain pine beetle (MPB) is an insect native to the forests of western North America and is also known as the Black Hills beetle or the Rocky Mountain pine beetle. The mountain pine beetle is a naturally occurring insect of the Rocky Mountain ecosystem. Mountain pine beetle infestations decimate lumber supplies. In the late 1990s, after several relatively warm winters, a massive outbreak resulted in the loss of millions of hectares of pine forest in British Columbia over the next 15 years.
