Study of brown bear at Sakhalin

The project on study and conservation of brown bear of Sakhalin oblast has been realized since 2009 with a goal to study the species ecology and develop scientific recommendations on managing its population. GPS-monitoring, phototrapping, visualizations of animals and study on trace of vital activity were used for investigation of the predator. Bear's territory usage, feeding, marking activity, relations with salmon and helminthofauna were studied. Conflict situations between human and bear were estimated.
