Hot on the heels of yesterday’s post The power of hope comes this wonderful story about the increasing population of wolves in Europe. I can’t recall what led me to the item in the UK’s Guardian newspaper but this is what I read:
Incredible journey: one wolf’s migration across Europe
Slavc is a wolf. In 2011, he began an epic 2,000 kilometre migration across Europe from Slovenia to Italy via the Austrian Alps. Several months earlier, he had been fitted with a collar that allowed his movements to be tracked in incredible detail. I talked to Hubert Potočnik, the biologist whose work made this possible.

Every year, Hubert Potočnik and his colleagues at the University of Ljubljana in Slovenia capture and collar a number of wolves in order to get a handle on the movements of these much-misunderstood creatures. In July 2011, he collared a young male that became known as Slavc. In June, I spoke to Potočnik for a feature that appears in New Scientist this week and he told me about Slavc’s extraordinary journey across Europe. What follows is an edited transcript of the interview …
HN: After you captured and collared Slavc in July 2011, he stayed with his pack for several months. Then, on 19 December 2011, he began to move. How did you know?
HP: We knew something was different because the GPS points showed that he had crossed two large motorways far outside of his natural territory.
Tell me about these collars. How do they work?
The collar is equipped with three types of different technology. It has a GPS receiver, a GSM modem to send SMS and also with a VHF radio transmitter as a back-up. We programme all our wolves to send a GPS signal every three hours, so we get about seven locations a day to give us continuous location sampling data.

HN: How would you sum up this experience?
There are lots of data about long-distance dispersal of wolves but there are very few cases where we have had the opportunity to follow an animal in such detail. Following Slavc across Europe offered a rare insight into the secret life of the wolf. It was one of the most amazing events in my life.
A quick web search came across this short but wonderful video; albeit without sound.

Two wolf cubs were documented in Lessinia Regional Nature Park on August 7, 2013. At the end of the video it is possible to partially see an adult wolf, the mother of the cubs, that was recognized as Giulietta. Giulietta and Slavc became famous because they brought together two wolf populations that were separated for over 150 years. Wolf Slavc originates from the Dinaric-Balkan wolf population and was collared in Slovenia. He travelled over 1500km over Austria to Italy, where he met Giulietta, originating from the wolf population from the western Alps (Piemonte region).
