Research profile

Falls within forest health, and is mainly focused on fungal diseases of trees in all stages of life, – from seedling, up to old-growth tree. It deals with forest and urban trees from over 10 species, and includes wide range of diverse fungal pathogens, but also insect pests.

Main subjects: i) forest pathology and protection; ii) silviculture; iii) mycology.

Ecostystems: European temperate and boreal forests.

Competence areas (in alphabetical order): - biodiversity and nature conservation; - dieback, wilt and canker; - disease identification and diagnosis;  - disease management, silvicultural and biological control; - drought, fire and wind (abiotic) damage; - economic impact; - endophytes and mycorrhiza; - forest decline and self-regeneration; - forest disease (damage) survey and modelling; - forestry and silviculture; - fungal community ecology and population genetics; - fungus-insect associations; - invasive and emerging diseases and insect pests; - logging and wildlife damage; - post-fire fungi; - root rot in forest stands; - shoot and foliar diseases; - stem decay.
