mountain pine beetle climate change

Exactly one generation per year is ideal for this diapause-free, or dormancy-free, species. 53: 559–572. The mountain pine beetle (MPB) is native to western Canada, but has expanded beyond its historical range and could become invasive, due to climate change and past forest management programs. Any opinions, findings, conclusions, or recommendations expressed in this publication are those of the author(s) and do not necessarily reflect the view of the U.S. Department of Agriculture. Mountain Pine Beetle With increases in global temperature and milder winters, the Mountain Pine Beetle is turning vasts tracks of forest into a wasteland. The mountain pine beetle (Dendroctonus ponderosae Hopkins, Coleoptera: Curculionidae, Scolytinae) is a native insect of the pine forests of western North America, and its populations periodically erupt into large-scale outbreaks. Nealis, V. and B. Peter. Download the high-resolution image. Mountain Pine Beetle: A Climate Change Catastrophe - YouTube The effect of warming temperatures will therefore differ depending on the species and the seasonality of warming. Researchers have long-suspected that the rapid growth in the population of the mountain pine beetle has been caused by climate change.

This information, combined with knowledge of the susceptibility of the various pine (Pinus spp.) 2015-41595-24254 from the USDA National Institute of Food and Agriculture. Pages 223–232 in T. L. Shore, J. E. Brooks, and J. E. Stone, eds. During outbreaks, the resulting widespread tree mortality reduces forest carbon uptake and increases future emissions from the decay of killed trees. Director, Communications and Marketingmatt.wood@unbc.ca Adapted for eXtension.org by Tom DeGomez, University of Arizona. * Kurz, W.A. species in Canada’s boreal forest, helped Canada devise a risk-based strategy for managing an unprecedented outbreak of mountain pine beetle in British Columbia and Alberta (Nealis and Peter 2008). Contact the Communications Office. At both sites, 33 metre-tall towers have been installed with a variety of scientific instruments measuring emissions of carbon dioxide from 1) standing forests where the trees have been killed by the pine beetle and 2) areas that have already been logged. Species with host trees in colder climates (e.g., mountain pine beetle and spruce beetle) have evolved to survive during cold winters and emerge as adults to attack trees during warm summer months. Questions about photography, video, social media, research and experts, or reporting on an event on campus? "...we’re able to track how a forest that becomes infected by the pine beetle evolves from being a carbon sink to a carbon source.". (2015), "“Bug Wood”: Climate Change, Mountain Pine Beetles and Risk in the Southeastern BRITISH COLUMBIA Logging Industry", Climate Change, Culture, and Economics: Anthropological Investigations (Research in Economic Anthropology, Vol. Communications Officerandrea.johnson@unbc.ca 2007. Communications Officer, NMPsonya.kruger@unbc.ca Could this sea of red forests in BC be contributing to climate change? Onsets of eruptions of mountain pine beetle demonstrated landscape‐level synchrony. “Mountain pine beetle and forest carbon feedback to climate change.” Nature 452: 987-990. Now, researchers from the University of Northern British Columbia, UBC, the Ministry of Forests, and Phil Burton and Tony Trofymow from the Canadian Forest Service are all trying to determine how the beetles themselves may be contributing to climate change by raising the levels of greenhouse gases in the atmosphere. new area of study, not much data yet available. He also studies specific characteristics of lodgepole pine and, more generally, the impacts of forest management on biodiversity. (top right) Larvae and galleries of the mountain pine beetle. The pine beetle infestation has led to very high levels of logging activity in northern BC and we’re interested in finding out what this activity will mean to the levels of carbon dioxide in the atmosphere. A new study published in the journal Nature highlights how climate change is promoting pine beetle outbreaks—and how the outbreaks are contributing to climate change. Essentially, recent winters have not been cold enough to kill the beetle and prevent its spread throughout much of the BC Interior. Mountain pine tree that feeds grizzlies is threatened by climate change, beetles Whitebark pine trees are expected to be added as a threatened species … 250-960-5626, Andrea Johnson  Possible causes have focused primarily on climate change induced stress on the trees, rendering them more susceptible to attack, as well as lower winter mortality in the larval stages of the beetle. Recent outbreaks of mountain pine beetle (Dendroctonus ponderosae) have impacted large areas of western North America.Climate and weather conditions influence beetle population dynamics, and managers and policymakers are concerned about the potential effects of climate change on outbreaks. Forest Service, Rocky Mountain Research Station 860 North 1200 East, Logan, UT 84321 ABSTRACT The mountain pine beetle (MPB) (Dendroctonus Mountain Pine Beetle and Climate Change ... How the MPB has Affected Climate Change. 1991. 2008. The mountain pine beetle (MPB) is native to western Canada, but has expanded beyond its historical range and could become invasive, due to climate change and past forest management programs. (AP) — Climate change, voracious beetles and disease are imperiling the long-term survival of a high-elevation pine tree that’s a key … Journal of Insect Physiology. Communications Officerpeter.james@unbc.ca Information Report BC-X-417. The mountain pine beetle has affected more than 900 miles (1,400 km) of trail, 3,200 miles (5,100 km) of road and 21,000 acres (85 km 2) of developed recreation sites over 4,500,000 acres (18,000 km 2) in Colorado and southeastern Wyoming; other outbreaks encompass the Black Hills of South Dakota and extend as far south as Arizona, and as far north as Montana and Idaho. Scientists in western Canada have been tracking the extent of the mountain pine beetle. 123: 1083–1094. The project is being funded by the Canadian Foundation for Climate and Atmospheric Science and the BC Forest Sciences Program, “Over the past 150 years, the levels of carbon dioxide in the atmosphere have risen considerably. 1) is an indigenous North American bark beetle that has been confined to the western part of the continent by the Rocky Mountains and the Great Plains geographical barriers. Other North American Examples of Climate Change and Insect InfestationsClimate Change and Predicting Geographical Forest Insect DistributionsThe Effect of Climate Change on Spruce BudwormThe Effect of Climate Change on Gypsy Moth. 3 processes to consider. 1991) and cold tolerance (Régnière and Bentz 2007). Considerable knowledge of this insect’s physiological responses to temperature is available, both in terms of development (Bentz et al. Historically, cold winters kept beetle populations under control. Researchers have long-suspected that the rapid growth in the population of the mountain pine beetle has been caused by climate change. 250-960-5420, Sonya Kruger Models were used to determine the area in Canada that is climatically most suitable to this insect. However, the risk of mountain pine beetle outbreaks in the western part of the country is likely to increase dramatically in higher latitudes and altitudes, while decreasing at lower latitudes and altitudes. “Clear-cutting can release enormous amounts of carbon to the atmosphere, for 10 years or more after harvesting. Risk maps developed for the country overlay the probabilities that the insect can achieve an adaptive seasonality and that it can survive the extreme cold of the Canadian winters, both under current and future climates. The bark beetle is a tiny creature with a massive impact. The mountain pine beetle (Dendroctonus ponderosae Hopkins, Coleoptera: Curculionidae, Scolytinae) is a native insect of the pine forests of western North America, and its populations periodically erupt into large-scale outbreaks. A. Matt Wood The research is being conducted at two sites north of Prince George: one near Crooked River Provincial Park and another at Kennedy Siding east of Mackenzie. Victoria, British Columbia, Canada, Natural Resources Canada, Canadian Forest Service, Pacific Forestry Centre. The forests of British Columbia are suffering a severe infestation with the mountain pine beetle (Dendroctonus ponderosae). Aesthetics Expanses of dead trees clearly hurt aesthetic values. However, the risk of mountain pine beetle outbreaks in the western part of the country is likely to increase dramatically in higher latitudes and altitudes, while decreasing at lower latitudes and altitudes. Dr. Fredeen earned his doctoral degree from the University of California at Berkeley. 2008. Out of more than 6,000 species, the best-known is probably the mountain pine beetle, which is only as big as a pencil eraser. Pine Beetle Resources: Forest Health: Mountain Pine Beetles, by the National Park Service. Dr. Art Fredeen is a forest ecophysiologist who is primarily interested in the way that forest management and natural disturbances (such as the mountain pine beetle infestation) influence the storage of carbon in sub-boreal landscapes. Currently, this beetle … The mountain pine beetle (Dendroctonus ponderosae) (Fig. Temperature-dependent development of the mountain pine beetle (Coleoptera: Scolytidae) and simulation of its phenology. (top left) Adult mountain pine beetle. In western North America, whitebark pine, a high elevation keystone species, and lodgepole pine, a widespread ecologically and economically important tree, have experienced extensive mortality in recent climate-driven outbreaks of the mountain pine beetle. Mountain pine beetles infest 90 percent of the park’s pine forests, and spruce beetle populations are rising fast. 47 … The current pine beetle epidemic may have been facilitated by global warming, but research involving UNBC professor Art Fredeen is now exploring whether beetle activity is now creating additional warming. Patterson, P.B. “Carbon dioxide is one of the most important greenhouse gases and forests are known to contain large amounts of carbon,” says UNBC Ecosystem Science and Management professor Art Fredeen, who is participating in the research. Due to the impacts of climate change, the mountain pine beetle represents a significant threat to the preservation of these iconic places. Comments from expert scientist: This study provides the possible insect outbreaks and their feedback to the ecosystem and relates it to global warming and forest carbon dynamics. Hoyle, Brian. During outbreaks, the resulting widespread tree mortality reduces fore … A mountain pine beetle crawls out of a ponderosa pine tree while another, right, remains in its hole in Green Mountain Falls, Colo., Aug. 24, 2006. To understand just how complex, scary and immediate climate change is, look no further than the case of the tiny mountain pine beetle. Download the high-resolution image. References Cited The burning of fossil fuels is considered to be the major culprit, but about 25% of the increase is due to deforestation. The Canadian Entomologist. BILLINGS, Mont. Old forests store tremendous amounts of carbon that they acquire during photosynthesis,” says Dr. Fredeen. In times of drought, beetle populations can spike, spreading to healthy pine trees. However changes in the beetles lifestyle may be an important contributor as well. “If trees are cut down or are killed by the pine beetle, they don’t absorb carbon anymore. The amount of lumber destroyed in the outbreak could surpass how much the mountain pine beetle killed in B.C. Modeling cold tolerance in the mountain pine beetle, Dendroctonus ponderosae. Bentz, B.J., J.A. Climate-related outbreaks of bark beetle species pose a serious threat to the temperate forests of Europe. “The Rocky Mountain national parks are of significant importance to Canadians, including Indigenous peoples who lived on the land for millennia. Up to 98% of MPB population is normally killed due to winter temperatures; however, with recent warmer winters, more individuals are surviving and the population has been able to grow more rapidly. Risk assessment of the threat of mountain pine beetle to Canada’s boreal and eastern pine forests. ... but climate change exacerbates their effects on one another. “Plight of the pines.” Nature Reports Climate Change 2: 52-53. Increased mortality of forest trees, driven directly or indirectly by climate change, is occurring around the world. B. The British Columbia Ministry for Environment says it is “currently experiencing an epidemic throughout the range of lodge pole pine forests in the province. Southern pine beetles are among the most destructive insects invading North America's pine forests today, and they're spreading farther north as … Mountain pine beetle … Climate change could be throwing common tree killers called mountain pine beetles into a reproductive frenzy. Photos of the mountain pine beetle, Dendroctonus ponderosae. Régnière, J. and B. Bentz. CU biologists Jeff Mitton and Scott Ferrenberg have studied the life cycle and activities of the mountain pine beetle, and they report, … MOUNTAIN PINE BEETLE AND CLIMATE CHANGE Jacques Régnière1 and Barbara Bentz 2 1Canadian Forest Service, Laurentian Forestry Centre Quebec, QC G1V-4C7 Canada 2U.S. These maps suggest that Canada east of the Rocky Mountains will remain inhospitable to this insect well into the future, except for parts of northwestern Alberta and the Atlantic seaboard. Logan, and G.D. Amman. 35), Emerald Group Publishing Limited, pp. photosynthesis takes CO2 from the atmosphere … Last year, our site at Kennedy Siding was green; now about 95% of the pine trees are infected.”, The sheer scale of the mountain pine beetle infestation means that salvage logging could have a very real impact on the link between forests, harvesting, and climate change. On average, the presence of outbreaking populations was highly correlated with outbreaking populations within the nearest 18 km the same year and local populations within 6 km in the previous two years. An examination of the distribution of climatically suitable habitats in 10- year increments derived from climate normals (1921-1950 to 1971-2000) clearly shows an increase in the range of benign habitats. By taking measurements at the same site over a number of years, we’re able to track how a forest that becomes infected by the pine beetle evolves from being a sink for carbon to a source. Broadcast-quality video footage is available. The current pine beetle epidemic may have been facilitated by global warming, but research involving UNBC professor Art Fredeen is now exploring whether beetle activity is now creating additional warming. UNBC professor Art Fredeen measures the precise amount of carbon being used by pine trees. Scientific instruments attached to the top of 33-metre towers are measuring the levels of carbon dioxide in the atmosphere above beetle-infected forests. This native insect kills weak and old lodgepole pine trees, thus promoting healthy growth of young forests. He has been a professor at UNBC for more than 13 years. Populations of this tree-eating insect have exploded over the last ten years due to warmer winters, devastating the majestic forests of … C. (bottom) Infestation of mountain pine beetle in the Black Hills National Forest, South Dakota. Figure 1. Effects of climate change on range expansion by the mountain pine beetle in British Columbia. Beetle outbreaks are becoming more common, and the biggest health concern is for lodgepole pine forests in western Canada is the mountain pine beetle. 250-960-5122, Associate Professor, Ecosystem Science and Management, © Copyright 2020 The University of Northern British Columbia. Related to Climate Change and Mountain Pine Beetle: This work is supported by New Technologies for Agriculture Extension grant no. Climate change may be a final result.”. existing lodgepole pine forests act as small carbon sink. 2008. In addition, climate-change-induced or -exacerbated mountain pine beetle outbreaks can have additional effects, such as altering the timing and quality of water runoff in affected forests. Overlays of annual mountain pine beetle occurrence on these maps were used to determine if the beetle has expanded its range in recent years due to changing climate. should existing climate conditions persist, according to … 250-960-5402, Peter James et al.
