Climate change can alter the impact of forest pathogens in trees
July 8, 2017
New research on projected climate changes indicates that climate change has an alarming potential to increase the damage caused to Norway spruce trees by a naturally circulating disease spreading fungus.
"This study shows the potential for future climate changes to alter the impact of forest pathogens, and the need to incorporate disease effects into future forestry planning as of now. As this is one of the first experimental tests of projected climate changes on a forestry host-pathogen system, there is an urgent need for further research on this topic," highlights Dr. Riikka Linnakoski from the department of Forest Sciences, Faculty of Agriculture and Forestry.
While much research has addressed the effects of projected climate changes on tree species distributions and their productivity, the potential impacts of pests and pathogens have received far less attention. However, these represent some of the most important threats to global forest health, particularly in regions where climate change is expected to be most severe, such as northern Europe. To mitigate the impacts of climate change, understanding the factors that trigger the development of forest tree disease epidemics and host susceptibility is essential.
