[ID: 431] Do mycorrhiza protect spruce from spruce bark beetle in periods of drought?

PI: Martin Goude

The aim of the proposed project is to investigate the relationship between soil moisture conditions, mycorrhizal colonisation and community composition and spruce resistance against European spruce bark beetle attack. The objectives of the study are to: • Examine the differences in spruce tree - mycorrhizal associations under different levels of soil moisture conditions (Work Package (WP) 1); • Manipulate soil moisture conditions to investigate the effect of drought on spruce-mycorrhizal associations (WP2); • Quantify the effect of acute drought on tree susceptibility to SBB in stands with different soil moisture conditions (WP3); • Quantify the 4-way relationship between stand conditions, drought stress, extent of mycorrhizal associations and susceptibility to SBB attack in the context of tree recovery (WP4).

[ID: 123] Long term monitoring of Ips typographus

PI: Mats Jonsell

Using pheromone traps and survey of killed spruce trees the long term changes are described and are used as a decision tool for forest management against the spruce bark beetle. Data are also used for scientific purpose, analyzing time series.
