Right now, lumber prices are soaring to record highs thanks to a  surge in pent-up repair, renovation and housing demand sparked by the coronavirus pandemic. The shades of dark green indicate healthy, undisturbed forest. The wily insects chew through the bark and convert the tree’s only defense mechanism—a toxic sticky, resin—into pheromones to alert thousands of their friends to join in on the mass attack, using it as a place to lay their eggs and eventually killing it. The beetles have spread to neighboring Alberta, where they have destroyed chunks of forest normally harvested for timber in addition to valuable caribou habitat.

Since 2005, about 40 sawmills have gone out of business following the collapse of the U.S. housing market and as timber shortages emerged from the fallout of the bugs. As winters warmed, more of the beetles were able to survive and extend their reach into areas that used to be too cold to live. as sawmills raced to process and export timber before the dying trees lost market value. Southern pine beetle populations within an area can range from undetectable to outbreak levels. Mountain pine beetles bore through the bark of pine trees, killing the tree. The treatment for pine beetles works best when applied proactively before an infestation is detected. Most southern pine species, if not all are vulnerable, but depending on the particular beetle, some pines are more susceptible than others. They are attracted to the odor produced by wind-thrown trees and trees damaged or killed by nature or man. The beetles aren’t dangerous under normal circumstances, but when trees are weakened due to lack of water from prolonged drought, they are more susceptible to attacks from bark beetles. Squashing these bugs is no easy feat, according to Caroline Whitehouse, a forest health specialist for the province of Alberta. Bark beetle data were from annual maps depicting the areal extent of tree canopy mortality due to 12 bark beetle species produced from aerial surveys, forest inventory measurements, and high-resolution satellite imagery (Meddens et al., 2012).

The situation is even worse in Europe, where several years of hot summers and dry winters has left drought-stressed trees ripe for the spread of bugs. Unique spectral signatures have been linked to different functional and structural plant traits, such as pigments at 400–700 nm, leaf structure at 700–1100 nm and plant … The mountain pine beetle (Dendroctonus ponderosae) is a small insect that lives most of its life in the inner bark of pine trees.

Adult females land on host trees in the early spring, bore into the pine tree and attract other beetles by secreting pheromones. Fire risk is highest in the first few years, when the needles are still on the dead trees. As infestation grows, nearby pine trees will likely be attacked as well. Photographer: Lino Mirgeler/picture alliance via Getty Images. Several species, such as the mountain pine beetle (Dendroctonus ponderosae), attack and kill live trees. The results do not project the forest management response to the current outbreak. Bark beetles are tiny insects with hard, cylindrical bodies that reproduce under the bark of trees. The severity of a blaze depends on the timing and intensity of the beetle infestation. Nowadays, remote sensing provides new opportunities to detect and map bark beetle infestation. The pests would feast on mature trees, providing fuel for forest fires that would then spur new growth. When you have an outbreak you have millions and millions and millions upon millions of beetles in the forest.”. Image Dimensions: 4984 x 1347 A pitch pine tree at the Wertheim National Wildlife Refuge in Shirley on Oct. 29, 2014 shows pitch tubes, or nodes of tree sap, which is a sign of the presence of the Southern Pine Beetle. 5 PINE PESTS Mountain pine beetle, Dendroctonus ponderosae An estimated 4 790 000 (2 294 400 m 3) lodgepole, white and ponderosa pine were recently killed over 46 750 ha in the Region, up slightly from 4 533 000 trees over 46 760 ha last year (Table 1, Map 3).

Chemical prevention is effective but too costly for large-scale use. Image Dimensions: 4984 x 1347 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. Southern pine bark beetles generally attack less vigorous or stressed pines, especially ones weakened by a continual drought, storm damage, strong winds, severe fires, old age, prevailing diseases, tree competition, and other insect infestations. Engraver beetles are readily attracted to drought-stressed pine trees and seldom attack a healthy tree. should existing climate conditions persist, according to an FEA report.

To be sure, there is still an ample supply of lumber down in the southern U.S. and forest inventory could grow as parts of the world become more adept at using technology to plant and grow faster-maturing trees, said Mark Wilde, an analyst at BMO Capital Markets in New York. The amount of lumber destroyed in the outbreak could surpass how much the mountain pine beetle killed in B.C. The Alberta government’s plans to manage the pine beetle infestation and prevent further spread.
