Recent spruce bark beetle calamity in Czechia
Original language description
Contribution in an international conference book of abstracts. The current bark beetle calamity (or catastrophe) has evolved progressively since 2015. The reason of the calamity is primarily a combination of climatically extreme periods and an ineffective forest protection system. Extremely warm weather and lack of precipitation weakened the forest stands by drought. The key problem is the late processing of bark beetle infested trees. The calamity spreads by both, natural and human means, from the north-eastern part of Czechia (northern Moravia and Silesia) south and westward, to south Moravia and nearly whole southern half of Bohemia. This areas are currently disastrously affected (except in the north-east, where the disaster has lasted already for many years). The main bark beetle species causing the outbreak is Ips typographus. The prognosis is negative for the coming years, in the sense of a further increase of volume of infested stands by bark beetles. There is an annual 1.5 to 2-fold increase in this volume (in 2019 was infested about 30 million m3 of spruce woods), for the following year, 2020, is a similar assumption. At present, only a favourable weather for at least two years could significantly influence this trend. Next actual the most endangered forests due to the bark beetles are pine stands.
