Opis:
The paper presents the first Polish bibliography on mouflon that includes papers published in the years 1945−2014. Forty seven publications show diversified interest in mouflon depending on its population size. Three different periods of research activity and publishing were distinguished. The first one (1945−1960) called the ‘opening balance' was the time of assessment of mouflon in Poland after the World War 2. At that time, mouflon status as an alien species was not taken into account. After the first unsuccessful attempts of introduction, ‘period of ambivalence' in the research and publishing activity occurred. In years 1961−1990 only nine publications, mainly popular ones, about the biology and occurrence of the species in Poland, and the history of its introduction were published. Along significant increase in number in the early 1990s, there was a significant increase in interest in this species among scientists. Majority of Polish research on mouflon has been published in the ‘renaissance' phase (since 1991). Papers deal with genetic testing, parasitology or telemetry, but knowledge about the role of mouflon in the ecosystem is still insufficient. Preliminary analysis of the number of publications and their subject (figs. 1 and 2) clearly shows that despite its 70−year history in Poland, the mouflon is still little−known species. Well−documented history of the reintroductions and their development is accompanied by almost complete lack of knowledge about the ecology. In terms of hunting management, protection or elimination of this species from Poland, there are currently no any reliable information, which could be useful for decision−makers. Mouflon has been a species of small numbers, not causing severe damage to forests and fields, and apparently not influencing negatively other ungulates in the areas of its occurrence. Not being a source of hunting successes or environmental problems it still remains outside the interest of scientists. At first mouflon was promoted, but later on, sometimes after many years, researchers tried to answer basic matters. Currently priority should be given to the research on i) the genetic condition of all local populations and evaluate their stability, ii) the interaction between mouflon and other wild ungulates, iii) its dietary composition in terms of damage to forests and fields, iv) parasites in isolated populations and v) assessment of the future of the species in Poland in the time of significant increase in wolf population.

Opis:
Wild boars (Sus scrofa) are regarded as food generalists and opportunists, whose great flexibility in food selection enables them to settle in various environments in a wide geographical area inhabited by them. Wild boars are perceived also as agricultural pests, since due to their dietary habits and a method of food seeking more crops are destroyed than consumed. In European habitat of wild boars, which undergoes long−term transformation, cultivated plants are an important ingredient of wild boars' summer and autumn diet. The issue of damage caused by wild boars has not been widely investigated in Poland so far. We analysed what is the crop damage caused by wild boars in summer and early autumn and whether the accessibility of crops (difference in crop acreage) determine the extent of this damage as well as we investigated if wild boars demonstrate preference to particular crops and how flexible they are while selecting food in the period of its oversupply. Research was based on 4215 reports on damage received by the Spała Forest District (C Poland) in 1999−2009 period. In analysed time wild boars caused damage in the wide range of crops. The greatest number of reports concerned damage in potato and in the fields seeded with cereals, while only a few – in beetroot, charlock, buckwheat and rape crops (tab. 1). Statistically significant and high correlation between the area of crops and the extent of damage was recorded. However, the damage was not serious enough to make the proportion of affected area grow bigger along with the area of crops (tab. 2). Although the analysed time span encompassed only 3 months, distinct differences in the extent of damage to cereal (excluding maize) and potato crops were marked. Crops affected the most in July included cereals. In August cereals were still the most affected crops, yet in September a radical change in wild boars' dietary preferences was noticed, while cereals distinctively came second after potatoes (fig. 2). In general, during summer and early autumn wild boars seeking food on fields damage a wide range of cultivated plants without a particular preference towards any species (evident opportunism in the food selection). The number of reported damage and its spatial extent is correlated with the area of particular species cultivation, yet the proportion of damaged area does not increase along with the crops area. Time, which wild boars can spend seeking for food out of the woods appears to be one of the limiting factors. Significant changes in the structure of damage in the short time span prove that wild boars are highly flexible in food selection, which can definitely facilitate their adaptation to new or changing environmental conditions.

Opis:
More than 3000 direct observations of 5900 mooses were used to investigate the sex structure and growth of the population living in the Kampinoski National Park (KNP, central Poland). The study used data collected by the park service since 1998. To confirm the hypothesis that the random observations will accurately describe the population structure the experiment was performed with a theoretical population. It was a collection of 102 numbers (1−39 for females, 40−81 for males, and 82−102 for calves). Sex structure of this population was 1:1 and the growth rate was 0.6 calf/female. To provide the randomness all ‘animals' were mixed and renumbered. Each time we drew 4 numbers (like 4 random moose observed). The drawn numbers were grouped into: males, females and calves. Results of the consecutive draws were accumulated, while sex ratio and growth rate of this hypothetical population were constantly recalculated. Changes in ratios with increasing abundance of ‘recorded' moose were observed. It was assumed that the accuracy of estimates of population structure will increase with the number of observed animals and ultimately the results of the draw will show real sex structure and growth of analyzed population. The draw was repeated three times. Each time the results confirmed the hypothesis. A similar procedure was performed for empirical data from KNP. The documented direct observation of moose throughout the year provides a reliable assessment of the sex structure and population growth. At a constant, daily assessment of gender structure requires longer observation time than evaluation of growth. Application of these traits based on a small empirical material and/or short follow−up time may result in significant errors. The sex structure of moose in KNP is at the level of about 1:2, while growth at 0.8 calf/female. The values of indicators describing these characteristics are higher than previously adopted for the purposes of hunting of moose use in Poland. It would clarify the methodology of recording observations – a clear definition of calf age (0−1 years) and a separate listing of moose treated as an independent one−year age group. It is also strict principle of not combining several separate observations (e.g. summary of the daily observations) as one independent observation. The method of accumulation of direct observation to assess the gender structure and growth should be tested in other deer species.

Opis:
The research analyses the use of space by the Wild boar living in a human−transformed landscape. CMR method was used. Animals were caught in two complexes from February 2009 to May 2010. Fifty boars were captured. Information on the location and hunting time were collected. Results show small range of activity of investigated Wild boars. Animals were shot within 4 km from the trapping place. The longest distance that Wild boar had passed amounted to over 20 km. Most boars survived up to 50 days from the date of their catch. The maximum survival time was 373 days. Small dispersion of Wild boars is probably caused by philopatry, sufficient food resources and shelter, and the ability to adapt to human presence near the refuges.

Opis:
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).

Opis:
The aim of the study was to demonstrate how the trophy quality of antlers of the red deer stags living in two large forest complexes in the Mazowsze region (central Poland) differs from those inhabiting other regions of the country. The study used the data describing the body and antlers weight of 272 stags shot in 2005−2014 in two large, separated from each other, forest complexes of Spała and Gostynin. The stags from both forest complexes do not differ from each other in body weight and antler forms. The average body weight of the stags at the age of 12 is approximately 120−140 kg. The characteristics of antler forms of the stags harvested by hunters may not reflect the actual state because of the use, in practice, of the selection criteria instead of random killing. The most frequently harvested antler forms of the selection stags in the age classes of 3−5 years and 6−8 years are regular eight−pointers and irregular twelve−pointers, respectively. However, the small sample size used and the specific rules of harvesting the older stags do not allow to characterize the antler forms of the stags older than 9 years. In the autumn−winter period, a decrease in the body weight of the rutting stags at the age of over 6 years, as well as of the young, 2−5−year−old, stags is observed. The loss in body weight in young stags is approximately 20%, while in older stags – 35%. The decrease in body weight in the autumn−winter period is not stable. The largest, representing nearly 50% of the total weight loss, was recorded after the rut. In the period between November and December even a slight increase in body weight was noted followed again by a decline by the end of the winter.

Opis:
The results of the inventory of damage caused by roe deer in a 2−year−old apple orchard in central Poland permitted to evaluate the browsing intensity as well as the relationship between biometric characteristics of trees and browsing intensity. The research showed that damage caused by the roe deer was mainly caused by shoot browsing, then rubbing the velvet antlers against trees and bark stripping. In one winter, roe deer damaged 35% of the orchard by browsing even up to 100% shoots on an individual tree. Significant differences were found between the intensity of browsing the different varieties of apple trees. The largest damage was noted in the case of the Ligol variety (35% of shoots on average), while the smallest – for the Idared and Golden Delicious varieties (approximately 5% of shoots on average). Branching and tree height were not found to affect the level of damage. When establishing forest hunting grounds, the Ligol variety, eagerly browsed by roe deer, should be planted on browsing plots, while Idared and Golden Delicious varieties – in orchards designed for fruiting.

Opis:
The aim of the study was to verify the hypothesis that the quality of male roe deer hunted in the Kielce region depends on the selected characteristics of the place of their earlier habitat (forest cover, soil) and the age of the individuals. As a criteria to verify that hypothesis we chose carcass weight, weight and height of the antlers and skull dimensions. Material consisted of carcasses and antlers of 1349 bucks harvested in 169 hunting districts in the Kielce region (central Poland). We found that the individual quality of male roe deer was diverse. Significant impact was found for the forest cover, diversity of soil types and age of the individuals. Roe deer with the smallest carcass weight, having significantly lighter antlers occurred in areas with the forest cover of over 40% (tab. 1). In turn, in the filed−type circuits, where the forest cover does not exceed 20%, bucks were much heavier and imposed massive antlers (fig. 1). There was also evidence that in areas where the fertile soil dominated (rendzina and chernozems) individual quality of deer was significantly better than in districts where poor fawn and rust soils predominated (fig. 2). The examined environmental factors had the greatest impact on carcass or antlers weight, as well as the dimensions of deer skulls in case of the youngest bucks and their impact decreased with age. Optimum of the individual's development in terms of carcass weight and antler falls at the age of seven. Bucks harvested in the Kielce region, in comparison to the other populations in Poland, were characterized by good individual quality and slightly subsided only to individuals from the Lublin Upland (tab. 2).
