On 29 July 2009, the staff of the OIKON Institute for Applied Ecology captured a wolf on Mt. Kozjak above Split and fitted it with a GPS collar. This was a male, about 3 years old and weighing 31 kg. Since it was collared, it has been intensively monitored, and it has been established that it has crossed the motorway several times, at several locations, including the Osmakovac green bridge animal crossing.
