In this paper, the visits of primarily Eurasian lynx (Lynx lynx) as a predator and roe deer as prey at the lynx marking site were analyzed. At the very beginning, the main features of each individual species and their life or coexistence with the lynx are described. Furthermore, by analyzing the data we collected through phototraps at the lynx marking sites, the duration and retention of the animals present, the activity and behavior of each individual was recorded, some males marking the territory independently, some females with cubs. Annual, monthly and daily dynamics of visits and activities of the Eurasian lynx (Lynx lynx) as predator and roe deer (Capreolus capreolus) as prey were compared. At the same time, the appearance of male and female lynxes through annual and monthly visits. It turned out that the most frequent visits are by the Eurasian lynx (Lynx lynx) as a predator and extremely less visits by the roe deer (Capreolus capreolus) as prey. Considering that Eurasian lynxes (Lynx lynx) are extremely territorial, the dominance of males and females on the territory of Gorski kotar was demonstrated
