We describe the results of our research on population dynamics among brown hares reared in enclosures and then released into suitable natural habitat. Radio-tracking was used to follow the fate of 60 released brown hares over a 4-year period, extending between November 2005 and November 2009. The survival rate among these animals after 12 months was estimated to be 37 %, with 22 tagged individuals surviving beyond 1 year post-release. The highest (40 %) level of mortality characterised the first month after release, while a second period of enhanced mortality coincided with the breeding season (altogether accounting for a 20 % mortality rate). There was no significant relationship between body mass and mortality rate in the first month following release. A natural cause of death was predation by mammals, which accounted for some 31 % of all losses. Remaining causes were poaching (13 %), hits by vehicles (7 %) and unidentified causes (9 %). However, in at least 40 % of cases, it was not possible to determine the date when a released animal died, to say nothing of the cause of death.

The paper presents the selected indicators of hare populations in Poland. The material consisted of 528 hares acquired during traditional hunts. For each hunted hare we specified its weight, sex and age. All individuals were classified into two age groups: the first comprised juveniles (up to 12 months of age), while the other – adults (over 12 months). The ratio of young individuals in relation adults varies a lot (26−56%). The males to females ratio was approximately 1:1 with a slight advantage in favor of females. Reproductive rate was between 0.36 and 1.26, while reproductive success – 0.7−2.7. Average weight of hunted hares ranged between 3.42 and 4.32 kg. No significant differences in body weight were noticed within gender groups (Z=1.298, p>0.05, Mann−Whitney U test). However, they were found within the age groups (Z=–9.657, p <0.05, Mann−Whitney U test).

Increases in red foxVulpes vulpes (Linnaeus, 1758) numbers and densities have been found in all European countries involved in the rabies vaccination program. In Poland, the number of foxes has increased steadily since the 1990s. Between 1999–2000, the average density of foxes reached 1.3–2 ind./km2 in some parts of the country. The aim of the study was to estimate the change in fox population densities in central Poland during 1980–2006, and to assess the effect these changes have had on the spatial distribution of natal dens, mean numbers of cubs observed at occupied dens and the sedentary/nomadic fox ratio. Estimations of fox population density and numbers were based on three methods: (1) counts of tracks in snow, (2) locations of natal dens and counts of cubs, and (3) the battue (driving) method. The three methods of assessment were used continuously in our study area over a period of 25 years. Average yearly results were analysed and comparisons made between the periods before and after implementation of the anti-rabies vaccination. The results obtained with all three methods show a significant increase in the fox population, when the two analysed periods are compared. Increases in fox population densities correlated with increased numbers of breeding sites being located outside forests, from only single ones in the 1980s to 24% of the total in 2005. The average number of cubs per occupied den decreased significantly (by 11%) in comparison with before the anti-rabies vaccination period. The great increase (more than 100%) in fox numbers observed using the battue (driving) method suggest, that nomadic animals can form an important part of winter population in our study area.
