Mountain Pine Beetle: A Climate Change Catastrophe - YouTube Aesthetics Expanses of dead trees clearly hurt aesthetic values. Forest Service, Rocky Mountain Research Station 860 North 1200 East, Logan, UT 84321 ABSTRACT The mountain pine beetle (MPB) (Dendroctonus photosynthesis takes CO2 from the atmosphere … 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. This native insect kills weak and old lodgepole pine trees, thus promoting healthy growth of young forests. Effects of climate change on range expansion by the mountain pine beetle in British Columbia. (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. 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. 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. During outbreaks, the resulting widespread tree mortality reduces forest carbon uptake and increases future emissions from the decay of killed trees. He has been a professor at UNBC for more than 13 years. B. should existing climate conditions persist, according to … 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. 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. 2008. The bark beetle is a tiny creature with a massive impact. Matt Wood 1991) and cold tolerance (Régnière and Bentz 2007). "...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.". Information Report BC-X-417. ... but climate change exacerbates their effects on one another. UNBC professor Art Fredeen measures the precise amount of carbon being used by pine trees. Historically, cold winters kept beetle populations under control. Populations of this tree-eating insect have exploded over the last ten years due to warmer winters, devastating the majestic forests of … Scientific instruments attached to the top of 33-metre towers are measuring the levels of carbon dioxide in the atmosphere above beetle-infected forests. 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. Patterson, P.B. References Cited 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). 2008. Mountain Pine Beetle With increases in global temperature and milder winters, the Mountain Pine Beetle is turning vasts tracks of forest into a wasteland. 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. * Kurz, W.A. Climate change may be a final result.”. 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. 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. Essentially, recent winters have not been cold enough to kill the beetle and prevent its spread throughout much of the BC Interior. Mountain Pine Beetle and Climate Change ... How the MPB has Affected Climate Change. “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. new area of study, not much data yet available. 250-960-5420, Sonya Kruger et al. Exactly one generation per year is ideal for this diapause-free, or dormancy-free, species. A. 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. Communications Officerpeter.james@unbc.ca Researchers have long-suspected that the rapid growth in the population of the mountain pine beetle has been caused by climate change. 250-960-5402, Peter James 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. Currently, this beetle … Mountain Pine Beetle Develops an Unprecedented Summer Generation in Response to Climate Warming Jeffry B. Mitton* and Scott M. Ferrenberg Department of Ecology and Evolutionary Biology, University of Colorado, Boulder, Colorado 80309 Submitted August 17, 2011; Accepted December 29, 2011; Electronically published March 22, 2012 Download the high-resolution image. Beetle outbreaks are becoming more common, and the biggest health concern is for lodgepole pine forests in western Canada is the mountain pine beetle. However changes in the beetles lifestyle may be an important contributor as well. (AP) — Climate change, voracious beetles and disease are imperiling the long-term survival of a high-elevation pine tree that’s a key … Photos of the mountain pine beetle, Dendroctonus ponderosae. 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. 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. The Canadian Entomologist. 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. To understand just how complex, scary and immediate climate change is, look no further than the case of the tiny mountain pine beetle. 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. Increased mortality of forest trees, driven directly or indirectly by climate change, is occurring around the world. Director, Communications and Marketingmatt.wood@unbc.ca Mountain pine beetles infest 90 percent of the park’s pine forests, and spruce beetle populations are rising fast. Pages 223–232 in T. L. Shore, J. E. Brooks, and J. E. Stone, eds. Modeling cold tolerance in the mountain pine beetle, Dendroctonus ponderosae. Bentz, B.J., J.A. 250-960-5122, Associate Professor, Ecosystem Science and Management, © Copyright 2020 The University of Northern British Columbia. Researchers have long-suspected that the rapid growth in the population of the mountain pine beetle has been caused by climate change. During outbreaks, the resulting widespread tree mortality reduces fore … Mountain pine tree that feeds grizzlies is threatened by climate change, beetles Whitebark pine trees are expected to be added as a threatened species … Adapted for eXtension.org by Tom DeGomez, University of Arizona. “Mountain pine beetle and forest carbon feedback to climate change.” Nature 452: 987-990. 3 processes to consider. “If trees are cut down or are killed by the pine beetle, they don’t absorb carbon anymore. 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. Communications Officer, NMPsonya.kruger@unbc.ca C. (bottom) Infestation of mountain pine beetle in the Black Hills National Forest, South Dakota. 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. “Plight of the pines.” Nature Reports Climate Change 2: 52-53. Scientists in western Canada have been tracking the extent of the mountain pine beetle. 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. Climate change could be throwing common tree killers called mountain pine beetles into a reproductive frenzy. 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. Pine Beetle Resources: Forest Health: Mountain Pine Beetles, by the National Park Service. Onsets of eruptions of mountain pine beetle demonstrated landscape‐level synchrony. 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. existing lodgepole pine forests act as small carbon sink. Logan, and G.D. Amman. CU biologists Jeff Mitton and Scott Ferrenberg have studied the life cycle and activities of the mountain pine beetle, and they report, … Due to the impacts of climate change, the mountain pine beetle represents a significant threat to the preservation of these iconic places. BILLINGS, Mont. 35), Emerald Group Publishing Limited, pp. 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. 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. 47 … Figure 1. The amount of lumber destroyed in the outbreak could surpass how much the mountain pine beetle killed in B.C. Dr. Fredeen earned his doctoral degree from the University of California at Berkeley. “Clear-cutting can release enormous amounts of carbon to the atmosphere, for 10 years or more after harvesting. 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. (top right) Larvae and galleries of the mountain pine beetle. 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. 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 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. Related to Climate Change and Mountain Pine Beetle: This work is supported by New Technologies for Agriculture Extension grant no. The effect of warming temperatures will therefore differ depending on the species and the seasonality of warming. 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. Broadcast-quality video footage is available. 53: 559–572. 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. 2008. Could this sea of red forests in BC be contributing to climate change? 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. Communications Officerandrea.johnson@unbc.ca (top left) Adult mountain pine beetle. In times of drought, beetle populations can spike, spreading to healthy pine trees. Questions about photography, video, social media, research and experts, or reporting on an event on campus? 250-960-5626, Andrea Johnson 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. Mountain pine beetle … This information, combined with knowledge of the susceptibility of the various pine (Pinus spp.) Climate Change and Predicting Geographical Forest Insect Distributions, The Effect of Climate Change on Gypsy Moth, Reducing Risks for Bark Beetle Infestations Associated with Firewood.
