Dynamics of 3 rabbit populations at 8 investigated micropopulations have been investigated during the period of 6 years. Spring ecological densities (Ne1) were kept at approximatively same level with the tendency of weak decreasing, no matter what the height of real periodical increase (RPi) and the degree of population and micropopulation exploitness in the previous year was. The values of RPi were varying per years and per populations. These variations were bigger in micropopulations. It was found the weak dependence of RPi height on fertility in the same year. It was not found the positive correlation between the spring ecological densities and RPi. Except in 3 cases of neutral relations, it was established less or bigger inverse dependence of densities and increasement. Rates of exploitation per years were equalized and were not following the moving of RPi in the previous reproductive period. Losses from the beginning of hunting season till the beginning of the reproductive period were evidently bigger than those on which were counted in planning these populations and micropopulations exploitations in Yugoslavia and in the world. It was established a strong positive correlation between RPi and losses that appeared from the beginning of hunting season to the beginning of next reproductive period. There were made conclusions about possibilities in planning the degree of exploitations.
