Coordinating the management of a population of large carnivores that spans international borders is greatly facilitated by using methods that are comparable. Although Norway and Sweden have both been monitoring wolverines by counting natal dens in the spring for many years, it is first from 2014 that the field protocols have been standardised.

To demonstrate the benefits of being able to present common data for a whole population the following animation traces the development of wolverines in Scandinavia from 1996 to 2010 - showing how the two populations have effectively grown together and become connected. View the animation.
