Under 2017 registered in total 657 wolverines in Norway and Sweden with the analysis of the collected DNA samples. In Sweden, it was the first time the survey was conducted throughout the country.
Provides a better surveillance
- Genetic analysis has become an important tool in monitoring predators in Scandinavia. The analysis provides information on population size, composition and exchange between subpopulations. In Sweden ago 2017 a pilot study in northern Sweden to evaluate the collection of DNA on wolverine can be an alternative method for calculating the population of the wolverine population. The trial is also underway in 2018 and the evaluation is expected to be completed 2019, says Maria Hörnell Willebrand, Director of Game analysis unit at the Environmental Protection Agency.
In a new report presents Rovdata results of DNA surveillance in Sweden, Norway and Finland the last two years. In Sweden registered last year 382 Wolverine individuals which 34 also demonstrated the Norwegian side of the border. From 657 wolverines identified in Scandinavia 2017 based on 2292 functioning samples each Wolverine average found 3,5 times.
