JCS Latvia's State Forests agreement No. 5-5.5_0004_101_16_4

Root rot caused by Heterobasidion and Armillaria species have significant economic impact on spruce stand development in Latvia. The economic losses in spruce stands are estimated to be at least 4000 EUR per hectare. Management practices are crucial to restrict root rot fungi development in managed spruce forests. The aims of the study are to analyze biological and anthropological factors limiting the spread of root rot, and to prepare recommendations for restricting root rot in intensive forestry conditions.

The objectives of study are:

  1. To determine resistance of conifer trees with different origin against Heterobasidion spp. and Armillaria spp.;
  2. To evaluate biotic and abiotic factors affecting Heterobasidion spp. and Armillaria spp. development;
  3. To analyze importance of logging residuals in spread of Heterobasidion spp.;
  4. To determine effect of stump removal on the fungal communities and spread of root rot fungi.
