    Currently in the natural environment tigers live in areas of eastern Turkey, through southern Asia to southeastern Siberia, Malay Peninsula and Sumatra, Java and Bali. Generally, the area of occurrence of these predators declined and some subspecies extincted, for example Javanese tiger, Balinese tiger, the Caspian tiger. Zoos are therefore still places where you can see live the big cats. They are also held in Poland’s zoos, where increasingly various programs are carried out for breeding and reproduction of this endangered species. The aim of this study was to analyze the population of tigers and selected indicators of reproduction and mortality in 2000–2006. On the base of data from the Handbook of Zoos, which contents the information about population of animals in Polish zoos, and from cards of animals the analysis of population of Amur tigers, Bengal, Siberian and White tigers in Polish zoos were carried out. The analysis included also some reproductive indicators. Polish population of tigers in the analyzed years decreased by approx. 45%. This decrease was affected to a greater extent females. Total loss was not compensated by the number of born and rearing offspring. To maintain the number of tigers in Polish zoos require intensive efforts to increase the reproduction of this species, and the purchase or "rent" females with proven reproductive capacity.
