There were an estimated 702 wolverines in the 2024/2025 season - an increase from 655 in the previous measurement, according to the Swedish Environmental Protection Agency.
"The wolverine population in Sweden is consistently above the national reference value of 600 individuals," Robert Ekblom, wildlife officer at the agency, said in a press release.
Wolverines are mainly found in mountain areas but have spread further south and east in recent decades.
The survey is based on a new method of DNA analysis of collected samples - which is considered more accurate.
"The results are less affected by factors such as climate change, which has previously made it difficult to inventory dens on several occasions," Ekblom said.
