In this work I deal in detail with analysis of roe deers and red deers management in the district of Námestovo for the last 21 years. I follow the growth of abudance trough statistical data from 1997 to 2018. I compare the current huntig plannig with my calculation that takes hunt, natural decrease ,the decrease caused by traffic accident and decrease caused by predators. In my work I also deal with predators like grey wolf, brown bear and wild cat mainly on their food and space demands. I analyze the changes of abudance with regard to the amendment to the Hunting Act no. 274/2009 Coll. and introducing an implementation decree number 344/2009 Coll. to practice, when it has been changed bonitations of many hunting grounds and of course increase in hunting plan after which abudance increase also.
