It is vital to manage pathogenic fungi in forest nurseries
Increased knowledge about pathogenic fungi in nurseries can improve the measures used to protect the tree seedlings. Therefore, in her doctoral thesis, Rebecca Larsson has studied the occurrence of pathogenic fungi on spruce, pine, and larch seeds; healthy pine needles, as well as fungal spores in the air around the nurseries. -

New camera technology to unveil bark beetle infested spruces at an earlier stage
With advanced drone cameras, researchers can detect European Spruce Bark Beetle infestations earlier and more accurately than ever before. With innovative new camera technology, they now aim to shorten the identification time even more and thus save more forest from attacks. -

More and happier pathogens in warmer Nordic countries
The majority of all known pathogens to global food production will thrive and reproduce faster in a warmer climate. Such generalizations are, however, not necessarily practically useful. A new report from SMHI and SLU estimates at a geographically higher resolution how 80 known plant pathogens are affected by climate change. -

Spruce bark beetle attacks in a time of climate change
Where and when does the spruce bark beetle attack? Petter Öhrn has investigated this as well as the spruce's defense capacity in his doctoral thesis. "It is particularly important for forest owners to find and remove infested trees in June". -

Ancient pine trees tell unexpected tale of ice and fire
Forest fires were more prevalent in the early post glacial forests in northern Sweden than previously anticipated. In unearthing three pines which had been buried for almost 10 000 years in Västerbotten, researchers from Umeå university and SLU found marks from multiple forest fires from a time when the ice sheet was still receding.
