Bark Beetle Outbreaks in Western North America: Causes and Consequences. He has cleverly categorized tree bark into seven types, which simplifies recognizing and remembering all the different kinds of bark. Addison, A.L. The bark of most young trees is smooth and thin. Over the period of a year or so, you’ll exhaust the sumac and they won't grow back. A.; Gray, D. R.; Vandygriff, J. C. 2011. Ecological consequences of mountain pine beetle outbreaks for wildlife in western North American forests. Scientists continue to monitor mountain pine beetle phenology and temperatures in high elevation forests in western US. Cultivated plant experts say that they should be planted in USDA Hardiness Zones 9 to 11 or in Zones 10 to 11, depending on the source. Hicke, J. A unique one to try is the ‘Seven Sons’ tree or heptacodium. Other common names for this tree include western birch, red birch, river birch, black birch, and western red birch. McDowell, N.; Pockman, W. T.; Allen, C. D.; Breshears, D. D.; Cobb, N.; Kolb, T.; Plaut, J.; Sperry, J.; West, A.; Williams, D. G.; Yepez, E. A. On some trees, the outer dead layers peel and drop off, revealing the inner layers of bark. Since there is no need to conserve moisture as their habitat is always wet, these trees do not spend energy on developing a thick bark. Jenkins, M.J.; Runyon, J. Continued growth pushes the bark outward, sometimes causing the outer layers to crack. Bark is analogous to an animal’s skin. Michael Wojtech’s book Bark, A Field Guide to Trees of the Northeast is a huge help. With the sudden freeze that happened recently, it's time to dig up and protect precious sub-tropical bulbs such as canna lilies, dahlias and gladiolus. Some trees, like paper birch, feature strips of bark that peel away from the trunk and take with them any light … The term tree bark refers to the tissues outside the vascular cambium. Hear All Things Gardening during Weekend Edition Sunday with VPR host Mary Engisch, Sunday mornings at 9:35. Predisposition to bark attack by root herbivores and associated pathogens: roles in forest decline, gap formation, and persistence of endemic bark beetle populations. ; Parsons, R. A.; Hadlow, A. M.; Cohn, G. M/; McAllister, S. S.; Popp, J. Meddens, A. J. H.; Hicke, J. Populations exist at low levels for many years until triggered by factors such as drought (7, 8, 9), windfall (10), and pathogens that stress trees (11). With 'stick season' upon us, we won’t be seeing green leaves on trees for another six months. Some are budding or blooming now, while other varieties are just green and doing nothing special. U.S. Department of Agriculture, Forest Service, Climate Change Resource Center. Regional Dynamic Vegetation Model for the Southern Colorado Plateau: A Species-Specific Approach, Spatiotemporal patterns of observed bark beetle-caused tree mortality in British Columbia and the western United States, Carbon stocks of trees killed by bark beetles and wildfire in the western United States, Climate change and bark beetles of the western US and Canada: Direct and indirect effects, Climate change could alter the distribution of mountain pine beetle outbreaks in western Canada, Climate and the northern distribution limits of Dendroctonus frontalis Zimmermann (Coleoptera: Scolytidae), Spatiotemporal patterns of mountain pine beetle activity in the southern Rocky Mountains, Drought predisposes piñon-juniper woodlands to insect attacks and mortality, Drought induces spruce beetle (Dendroctonus rufipennis) outbreaks across northwestern Colorado. Remove some by starting now with a chainsaw or handsaw all the way down to the ground. There are believed to be nearly 1,000 different species, ranging from tall shrubs to large trees. In conjunction with their phenology model, they aim to evaluate the relative effects of temperature on cold-induced mortality and seasonality of mountain pine beetle population success and range expansion. Once a trigger occurs, population growth depends on the scale of the trigger, continued favorable conditions including suitable host trees throughout the landscape (13), and temperatures that favor winter beetle survival (14, 15) and successful tree attacks in the summer (16). Why not plant some trees and shrubs in your lawn and landscape that boast beautiful-looking bark? ; Ayres M.; Berg E.; Carroll A.; Hansen M.; Hicke J.; Joyce L.; Logan J.; MacFarlane W.; MacMahon J.; Munson S.; Negron J.; Paine T.; Powell J.; Raffa K.; Regniere J.; Reid M.; Romme W.; Seybold S.; Six D.; Tomback D.; Vandygriff J.; Veblen T.; White M.; Witcosky J.; Wood D. 2009. Researchers are analyzing two range-wide genetic variation studies of species with large distributions: eastern hemlock, which is being decimated by an exotic insect, and ponderosa pine, a species with isolated populations of special concern given their susceptibility to climate change, development, and bark beetles. Vasanthakumar, A.; Delalibera, I.; Handelsman, J.; Klepzig, K. D.; Schlooss, P. D.; Raffa, K. F. 2006. Forest Science 60(2). 2) Some trees in very hot/dry climates shed leaves in the summer rather than winter, in order to conserve moisture. Should you cut back your hydrangeas? The National Park Service points out that you can recognize some trees by smelling their bark. he effectiveness of vegetation management practices for prevention and control of bark beetle infestations in coniferous forests of the western and southern United States. 2013. They benefit us by purifying water, air and creating better social conditions. Temperature drives bark beetle physiological processes such as larval development and cold hardening, thereby directly tying temperature to population growth. R. 2008. Apr 6, 2018 - Explore Steve Ferrick's board "Tree Bark Identification" on Pinterest. The outer bark, which the compressed cork layers, is also waterproof. For example, the southern pine beetle can have up to 7 generations per year in the warmest part of its range (3). ; Romme, W.H. Contact: Kevin Potter, Economic impacts of insect outbreaks triggered by climate change. Prior to the activity during the late 2000s, expanding infestations of southern pine beetle had not been detected in the southeast or northeast since 2002 (3). However, even with warming temperatures, the mountain pine beetle throughout its current distribution may not be able to produce multiple generations in one year since it is constrained by evolved adaptations16. Changes in temperature and precipitation patterns will also indirectly affect bark beetles through effects on community associates (24, 25, 26) and host trees (27, 28). Hansen, E. M.; Bentz, B. J.; Powell, J. Economic impacts of insect outbreaks triggered by climate change. In the past, American Indians built dome-shaped houses made of poles, leaves and tree bark., called wigwams. If you have two different types of trees in your backyard you should compare and contrast them to see if you can find the difference. Before sharing sensitive information, make sure you’re on a federal government site. A.; Hayes, J. L. 2012. Over a year into my project, I recognize most tree species by their bark, but still struggle to describe them for others. T. Tran, J. K.; Ylioja, T.; Billings, R. F.; Regniere, J.; Ayres, M. P. 2007. [pdf] Forest Science 60(2). The site is secure. An official website of the United States government. Species that do not currently occupy the full extent of their host tree range are considered to be at least in part limited by climate. A.; Amman. Ornamental cherry trees are a great choice with copper-colored bark, and though sycamores are usually found in warmer climates, some can grow in the Champlain Valley and warmer zones here in Vermont. Basketry. Because climate affects the amount a tree grows and the thickness of the rings, scientists use tree rings to learn about past climate. Community associates that are both beneficial and harmful to bark beetles will also be influenced by changing temperature (29) and precipitation patterns, although less is known about these interactions. Short-term tactics can be used to reduce ongoing infestations by directly manipulating beetle populations, although due to cost these are limited to use in high value areas such as campgrounds and the wildland urban interface. The economic and social costs of outbreaks, however, can be significant. This tree is a source of food and lodge material for the common North American beaver. The bark of different trees has evolved to withstand the environment in which each species occurs. Reuse the pumpkins on your porch step by turning them into planters for small succulents! 3. Forest Science 60(2). Q: I just bought a new little property in Londonderry. In the United States (US), species in the genera Dendroctonus and Ips are the primary culprits. Plant them close to your house so you can enjoy them in winter. Semiochemicals, communication compounds released by beetles and trees, can be used to attract and repel beetles of some species (31, 32, 33). Bentz, B.J. ; Hulcr, J.; Koch, F. H.; Earnhardt, T.; McKerrow, A. J.; Dunn, R. R.; Collazo, J. Breshears, D.D. BioScience 58(6):501-518. The bark serves as a protective layer for the more delicate inside wood of the tree. We've closed our comments. Whether rough or smooth, a tree's choice in bark boils down to strength versus speed. It is clear, however, that these types of management strategies are only efficacious prior to the onset of an outbreak. Cullingham, C. I.; Cooke, J. E. K.; Dang, S.; Davis, C. S.; Cooke, B. J.; Coltman, D. W. 2011. This is valuable and useful information that can help you to learn more about the birch tree. www.fs.usda.gov/ccrc/topics/insect-disturbance/bark-beetles. In spring, begin mowing them every two to three weeks. Mesquites are one of the most common trees that are found in parts of Mexico and Southwestern United States.Mesquite is a member of the genus of leguminous trees, Prosopis, that has about 40 species under its umbrella, including peanuts, clover, alfalfa, and beans. Most are light in color — either white, beige, or light tan — to reflect the sunlight from the bark of the tree. ': Learn How To Encourage Yours, Pumpkin Planters Perk Up Porches And Holiday Tables, For assistance accessing our public files, please contact publicfile@vpr.net or call 802-655-9451. It has tan-colored bark and is very attractive in the landscape. The effect of warming temperatures will therefore differ depending on the species and the seasonality of warming. ; Belnap, J.; Anderson, J.J.; Myers, O.B. Species that infest and reproduce in trees in warm habitats (e.g., some southern pine beetle populations and piñon ips) have evolved physiological mechanisms that allow for multiple generations in a single year. So why is tree bark brown, grey or some other colour, but rarely green? As the tree grows, the bark layer thickens with the outermost tissue eventually dying. Fettig, C. J.; Klepzig, K. D.; Billings, R. F.; Munson, A. S.; Nebeker, T. E.; Negron, J. F.; Nowak, J. T. 2007. Birch-bark or paper-bark cherry (Prunus serrula) will make you weak in the knees. — Ali, in Londonderry. Changing climates, changing forests: A western North American perspective. Chapman, T. B.; Veblen, T. T.; Schoennagel, T. 2012. G. D. 1991. Bentz, B.J. The trees may survive one night of light frost, but they are … With continued changes in climate, many tree species will be exposed to conditions that are potentially less suitable for optimal growth, thereby making them more susceptible to bark beetle attacks. Some practices can increase landscape resiliency to bark beetle outbreaks. These plants are often protected by thick bark past where local herbivores can reach. The .gov means it’s official. Forest Ecology and Management 308:198-206. ; Turner, M. G.; Romme, W. H. 2008. ; 2005. Impact of minimum winter temperatures on the population dynamics of Dendroctonus frontalis, Temperature-dependent development of the mountain pine beetle (Coleoptera: Scolytidae) and simulation of its phenology. Here are a few: Trees: White birch and Himalayan white birch are great, hardy choices for this region though these are susceptible to a pest called the bronze borer. Raffa, K.F; Aukema, B. H.; Bentz, B. J.; Carroll, A. L.; Hicke, J.A. As Steve Schafer says, palo verdes are among relatively few examples of trees with green, photosynthetic bark. Absorption of sunlight by a tree’s bark causes heat gain. ; Rich, P.M.; Price, K.P. ; Floyd, M.L. Design & Materials: Homes for Different Climates. Federal government websites often end in .gov or .mil. Oddly enough, in northern climates, mid-winter warming of a tree’s bark is not a good thing. “Bark contains many different compounds, including … Birch Tree Photos. B.; Hubbard, R. M.; Negron, J. F. 2012. Rocky Mountain Research Station scientists and cooperators are working on a project that will modify the SIMPPLLE landscape model to address the impact that climate change and disturbances such as bark beetles, wildlife and exotics species will have on the distribution and abundance of vegetation species. Barbara Bentz, Rocky Mountain Research Station, Kier Klepzig, Southern Research Station, An archived version of this topic paper is available. This peculiar tree is called Eucalyptus deglupta, commonly known as the Rainbow Eucalyptus, and also known as the Mindanao Gum, or the Rainbow Gum. For a more comprehensive list of medicinal tree bark, take a look at 10 Medicinal Trees that Heal Virtually Everything. These types of control can have a significant influence on non-target species such as other invertebrates, fish and birds however, which must be considered. The trees do best in a tropical or subtropical climate. Bark Beetles and Climate Change in the United States. Boone, C. K.; Keefover-Ring, K.; Mapes, A. C.; Adams, A. S.; Bohlmann, J.; Raffa, K. F. 2013. 2012. Although there is more uncertainty in predicting precipitation patterns than temperature, drought and high temperatures can both play roles in outbreak initiation (7,8, 9). Hundreds of bark photographs are spread across my office floor. These houses were called wigwams. Applied chemical ecology of the mountain pine beetle. Shagbark hickory is another favorite, with its pronounced, almost camouflage bark. ;Vandygriff, J. C.; Jensen, C.; Coleman, T.; Maloney, P.; Smith, S.; Grady, A.; Schen-Langenheim, G. 2013. Contact: Barbara Bentz, Regional Dynamic Vegetation Model for the Southern Colorado Plateau: A Species-Specific Approach We will review and synthesize the literature involving currently used pest assessment methods, including monitoring and survey methods, summary analyses, valuation procedures, reporting metrics and standards and error and accuracy estimation. Cultural practices for prevention and mitigation of mountain pine beetle infestations. Forest ecosystems have evolved with native bark beetle outbreaks. Forest Ecology and Management 259:660-684. There are great native plants to choose that have interesting bark colors, patterns and textures in the winter time. Bark beetles that infest and reproduce in live trees are capable of causing landscape-wide tree mortality. You just need to know which variety you've got before you begin. ; Balice, R.G. Saab, V. A.; Latif, Q. S.; Rowland, M. M.; Johnson, T. N.; Chalfoun, A. D.; Buskirk, S. W.; Heyward, J. E.; Dresser, M. A. Bentz B.J. Bark beetles and fire are two important disturbance agents in forest ecosystems that can have reciprocal interactions. Send us a message or get in touch by tweeting us @vprnet. Acacias grow prominently in Africa and Australia, but have presences in parts of Europe and North and South America as well. Leaves = photosynthesis, so a bit of a problem, however the fresh bark under the fallen shreds is green and can do at least some of the photosynthesis. University of Utah Press, ISBN 978-0-87480965-7, 42 p. Costanza, J.K.l. Impacts of bark beetles on ecosystem values in western forests: A synthesis Trees use their outer bark for different purposes, but mainly for protection against water loss and predators. In some species the bark looks similar throughout the life of the plant, while in others there are dramatic changes with age. ; Kastens, J.H. Mesquite trees are quite hardy and are well adapted to dry environments. There are so many sumac trees. Nowak, J.; Asaro, C.; Klepzig, K.; Billings. This could lead to increases in bark beetle populations, or in some cases decreases, depending on the species and geographic location (4, 16). Forest Ecology and Management 269:52-59. Acacia is a wide genus of plants that thrive in arid, desert climates. Other factors such as competition may play a role, but temperature can be particularly limiting. Although basic outbreak dynamics and impacts of some bark beetle species have been described, characterizing and quantifying these impacts on ecosystem functions and services remains a significant challenge. ; Carroll, A. L.; Zhu, J.; Stahl, K.; Moore, R. D.; Aukema, B. H. 2012. Insects and herbivores want to eat the leaves off woody plants. You can also leave a voicemail with your gardening question by calling VPR at (802) 655-9451. Being able to point out the differences in the tree bark will help with tree identification. Following wild and prescribed fire, bark beetles can preferentially attack fire-injured trees and contribute significantly to mortality of trees that would otherwise survive their injuries. Even common apple tree bark has medicinal properties when used to treat fevers and diarrhea. The https:// ensures that you are connecting to the official website and that any information you provide is encrypted and transmitted securely. There is also potential for species currently limited to southern latitudes within the US to expand their ranges northward with projected increases in temperature, although detailed information regarding thermal influences on fitness is lacking for the majority of bark beetle species.

Don’t remove all the sumac trees, as they add color in the winter and they are a bird food source plus they are a good pollinator. Send your gardening questions and conundrums and Charlie may answer them in upcoming episodes. Gitau, C. W.; Bashford, R.; Carnegie, A. J.; Gurr, G. M. 2013. If you want to protect them for winter, now is a great time to not only cut them back and dead-head the flowers, but also do some other winter care prep methods. Splits can occur on the trunk of the tree as well as on branches. Long-term strategies such as thinning and prescribed burning can optimize stand development trajectories, alter microclimates within stands, affect dispersal and host finding by beetles, and promote tree vigor and a diversity of species and age classes (13, 30). Emergence synchrony occurs via temperature-driven thresholds in development (17) and diapause (18), a dormant state of reduced respiration. Bark is a tree's first line of defence. The smoothness of their bark helps check the tendency of other rainforest plants to grow on them. Contact: John Lundquist, Assessing genetic variation of forest tree species at risk Other species of bark beetles such as piñon ips can be triggered by similar conditions, although their population dynamics are more directly tied to the condition of the host tree (12). 2013. Between 1997 and 2010 more than 5 million hectares were affected by bark beetles in the western US, most notably mountain pine beetle (D. ponderosae), spruce beetle (D. rufipennis), and piñon ips (I. confusus)(1), and the amount of carbon (C) in trees killed by these insects exceeds that of C in trees killed by fire (2). Mountain pine beetle female chewing through the phloem of a host tree to deposit eggs. 2012. Bark splitting can occur in response to various environmental factors at different times of the year. The multi-coloured streaks on its trunk comes from patches of outer bark that are shed annually at different times, showing the bright-green inner bark. Such warming may cause rapid fluctuations in the temperature of the cambium, that all-important, thin veil of regenerative cells between the bark and the wood. Powell, E. N.;Townsend, P. A.; Raffa, K. F. 2012. They also are investigating spruce beetle physiological response to temperature, including diapause, to improve and further refine a phenology model for this insect. The key is to cut the shrubs back every two or three years, as it’s the new growth that has the most color on its bark. Beech developed smooth bark, which is difficult for epiphytes to gain a foothold on, because it evolved in tropical climates where epiphytes can amass in such large numbers that they break branches or pull down trunks; it maintained this trait as it migrated to cooler climates. Instead, choose the river birch tree variety. It is clear that bark beetle outbreaks significantly influence forest ecosystem dynamics and carbon cycles, and research suggests warming summer and winter temperatures are major drivers of beetle population outbreaks across the US, and apparent range expansion in some species (4, 5, 6). Descriptive models have been developed to aid managers in choosing trees for removal following fire to reduce additional tree mortality (35). B.; Fettig, C. J.; Page, W. G.; Bentz, B. J. Ornamental cherry trees are a great choice with copper-colored bark, and though sycamores are usually found in warmer climates, some can grow in the Champlain Valley and warmer zones here in Vermont. DeRose, R.J.;Bentz, B. J.; Long, J. N.; Shaw, J. D. 2013. Simulating effects of the southern pine beetle on regional dynamics 60 years into the future. 2013. If you want to be a tree identification expert, one of the best things you can do is buy a … Contact: Thomas Holmes, Climate Change Influences on Mountain Pine Beetle and Spruce Beetle Phenology and Associated Impacts in Western North American Forests Why Some Trees Have Rough Bark and Some Trees Have Smooth Bark In truth, there are advantages to rough bark and there are other advantages to smooth bark, too. Bentz, B.; Klepzig, K. (January 2014). The answer, according to Dr Miller, depends on the chemical compounds found in the cell walls of the tissue layers that make up bark. Increasing minimum temperatures is one factor attributed to northward range expansion of the mountain pine beetle in Canada. Some Indian tribes that moved frequently built cone-shaped tepees out of buffalo skins or bark. Bark beetle-caused tree mortality can influence subsequent fire behavior, although the spatial and temporal dynamics are complex (34). Tree wrap varies in color, based upon its material. Davis, R.S. We'll learn about the different varieties of  cactus, why and when they bloom and how to encourage yours to bloom this winter! Sambaraju, K.R. While its height is impressive, it's really the tree's multicolor bark that makes it stand out. The strong role of temperature in population growth, and the role that reduced precipitation can play in host tree stress, suggest that climate change-associated shifts in temperature and precipitation will influence bark beetle populations in future forests.
