In the master thesis is being analized an elementary population of elk in the Tyruliai botanical – zoological reserve. With a help of the survey it was being tried to identify the elk distribution in the territory in summer, autumn, winter and spring. Also, the behaviour patterns of rutting of the elks which live in the reserve were analyzed as well. The patterns analyzed were as follows: the characteristics of the territory chosen for rutting, the beginning and the end of the rut. Object of the work - an elementary population of european elk (Alces alces) living in the territory of the Tyruliai botanical – zoological reserve. The aim of the work - to examine the behavior patterns and the patterns of rutting of elks living in the territory of the Tyruliai botanical – zoological reserve, also, to identify the dynamics of the dimensional distribution in the territory according to the seasons. Methods of the work – visual observation of the elks and the accounting according to the piles of the excrements in the winterings. The results of the work – it was estimated that during the research period there were 25-30 elks hibernating in the territory of the reserve. The favourite elk places of hibernating were plots with wide leafy areas with lots of bushes. In the summer pastures there were open and half-open wet biotopes such as low swamps and shrubberies. For rutting territories elk chose plots with wide areas of shrubberies and leafy swamps. The former elk rutting date in the territory was stated on the 23 of August and the latest - the 26 of September.
