The Laboratory for Research and Monitoring of Large Carnivores carries out various activities to determine anthropogenic influences on the populations of large carnivores, bears, wolves and lynx, as well as on numerous other large and medium-sized mammals.

In this regard, the Laboratory conducts monitoring of wildlife motorway crossings over green bridges, the number of road kills, monitoring of the influence of other linear structures (gas pipeline, railway tracks etc.) built in habitats of large carnivores, as well as the impact of other anthropogenic structures (wind power plants, landfill sites etc.) on their populations.

The research conducted within the Laboratory focuses on determining the distribution, home range , the fragmentation of the habitat, the number and the nutritional structure of medium and large mammals, especially large carnivores.

The results obtained are used in analyses of the prediction of tendencies of certain species of animals towards a certain type of habitat as bases for determining the importance of certain areas for conservation of stable populations of the investigated species. The results of the above-mentioned research and monitoring are for preparation of documents such as Environmental Impact Assessment, Appropriate Assessment, Nature Impact Assessment, etc.

To carry out these researches and monitoring, we use modern methods such as telemetric animal tracking using GPS/VHF collars, digital photo trapping methods, GIS analysis of the data obtained etc.

The head of the Laboratory is Goran Gužvica, PhD and the members are Marko Augustinović, mag. ing. silv. and Monika Petković, mag. educ. biol. et chem. External associates are professor Lidija Šver, PhD and Ratko Popovic, bacc. ing. agr.

Within the Laboratory, the following projects have been implemented:
