How fires, storms, and bark beetles will shape the future of Europe’s forests TUM researchers have modeled how bark beetles, storms and wildfires could affect Europe’s forests. A doubling of forest damage is possible.

Researchers calculated how disturbances like #wildfires, storms, and #barkbeetles, fueled by #climatechange, could transform Europe’s forests by 2100. #ForestDamage could increase, especially in Southern and Western Europe: go.tum.de/187640

🪲 Improving bark beetle control strategies
A JFR study from Serbia finds wet pheromone traps are about twice as effective as dry ones, and temperature strongly affects beetle flight.

The photo shows a portion of a small fallen tree trunk stripped of its bark and full of grooves bored by bark beetles. The wood is a golden brown. The curvy grooves are darkened almost to black. They look like runic writing curling around the trunk. The trunk is resting on a bed of small leafy understory plants.

Tree mortality from insects is rising across Europe In Europe, more trees are dying from insect infestations. Broadleaves cope better than conifers, as heat and drought worsen the issue.

🌲🪳 Tree mortality caused by insects is on the rise in Europe. Warm, dry regions are the most severely affected. New study in @globalchangebio.bsky.social www.wsl.ch/en/news/tree... #Forests #ClimateChange #Treemortality #Barkbeetles

A plot from the field choice experiment. Fresh-cut Norway spruce and Sitka spruce logs are arranged in an alternating ‘open’ square, with a low-dose pheromone lure attached to a central post. This plot is located at the forest edge; the timber stack is visible in the background in corner of the clearfell.

Colonization rates of Ips pini in relation to numbers of propagules released (log scale) in (a) 1 m caged and (b) 10 m field scenarios. Colonization was defined as at least one billet out of four per release replicate having at least one F1 adult present. Each data point represents one release replicate. A binomial generalized linear model was fit to the data to produce each line.
