- Forest owners are worried about a fungus that attacks pine forests. It is the fungus, dry catfish that has now spread to the county and in the long run can lead to major economic losses for forest owners.
- Törskate is a root fungus that forms large crayfish wounds that eventually choke the water and nutrient transport to, for example, a branch or that which is above the wound if it is on the trunk.
- “Dry skating seems to be a future problem with us in Jämtland as well”, says Jörgen Sundin, forest consultant at the Swedish Forest Agency, to P4 Jämtland.
Törskate has been common in Norrbotten and Västerbotten for some time, but only now has it spread to Jämtland County. Last year, inventories were made of young pine forest on between 10-30-year-old trees in Norr- and Västerbotten and it showed that in some places up to 25 percent of the young forest was so damaged that it did not meet the requirements of the Forest Management Act. In Västerbotten, most of the damage was due to moose grazing, but in Norrbotten, the damage from the dry catfish was greatest.
