The master’s thesis analyses semi-naturally bred and released to the wild lynx and wild lynx (Lynx lynx L.) spatial distribution in Lithuania’s forests. The thesis object – two released female lynxes that were born and adapted in Petras Adeikis kennel, also free lynxes that live in Lithuania’s forests. Thesis goal – to find out in captivity bred and released lynx and wild lynx spatial distribution peculiarities. Thesis methods – applying the point data collected from the released lynx’s collars and the internet survey data (in use with ArcGIS, Microsoft Excel and Statistica programs) to find out significant environmental factors, which influence lynx distribution. Thesis results. Lynxes that were bred in semi-natural conditions, once released, took up very similar size areas as wild lynxes. Released lynxes especially avoided main roads in their neighbourhood (Ivlev index reached -0.89 and -0.76). They were more likely to choose sparsely human populated areas, yet in some cases they were tolerant to high human density areas.
