The pace of bark beetle infestation should continue in 2021, unless there are extreme weather conditions which are unfavorable for bark beetles and favorable for trees. With a doubling of infested trees in 2021, the volume of damaged wood would reach 80 to 120 million m³ already.
According to Czech Forest, 450 million m³ of spruce are at risk in the country.
After 2021, a decrease in infestation is to be expected which is mostly due to a general reduction of spruce stock. Czech Forest expects that a gradual shift of the calamity towards higher altitudes is likely which is also going to slow the spread of the parasites.
In general, the risk of a spread of bark beetle infestation remains in most spruce forests. This means that half of the Czech Republic’s growing stock and forest area are affected.
