On October 17, 2022, experts from the Biotechnical Faculty, Department of Biology, captured a 22 kg female wolf, about six months old, and fitted her with a GPS telemetry collar. Local hunters named the she-wolf Neža. After biometric measurements, samples for genetic analysis and a health check, the female was released back into the forests of Jelovica about an hour after sedation.

The she-wolf is this year’s offspring of the Jelovica pack, in which we regularly detected 6 pups in addition to 4 adult wolves using the photo trap until mid-September. Since October we have detected 4 adult wolves and 4 pups only.

Neža is the third wolf captured and telemetrically monitored in the Jelovica pack in the last three seasons. Before her, two young males were monitored. The first one – Jelko – left the pack and settled in the area between Italy and Slovenia in Rhesia (he died in road traffic), and the second one – Mojmir – the signal was lost about two months after the monitoring started. The data sent by the  collar allows detailed monitoring of the wolf’s movements, preferences and organization of the Jelovica pack, as well as the process of dispersal or independence of the young wolf.
