Opis:
The wild boar is an omnivorous animal that disturbs the top soil layer by foraging (rooting). In some regions of Europe seasonal fluctuations in rooting have been observed. Wild boars not only eat plants, but also strongly modify their habitat. In the Białowieża Forest wild boar most frequently visit oak−hornbeam forests growing on fertile soil. On sites where the forest floor is covered with dense vegetation germination of seeds is difficult, and wild boar rooting can promote the removal of diaspores from deeper layers of the soil seed bank. The aim of this study was to assess the impact of wild boar rooting on the soil seed bank in a natural oak−linden−hornbeam forest. Observations were carried out on permanent plots in the strictly protected zone of the Biało− wieża National Park. Samples of the soil seed bank were taken from plots which showed varying intensities of wild boar rooting (frequency and average percentage of exposed ground surface). Areas to be sampled were selected on the basis of archival data. Research was conducted by the seedling emergence method during two vegetation seasons. Altogether, 7985 seedlings of 67 taxa germinated from 240 soil samples. The highest number of germinated seedlings and species were found in the highly rooted plots. In all the series dominant species was Urtica dioica. In the soil seed bank 19 species of anemochory germinated, and accounted for 27.5% of all species present in the seed bank of all series. Permanent wild boar rooting increased the species richness in the soil seed bank and increased the amount of species with higher light requirements.

Opis:
The number of wild boars considerably increased in Poland at the beginning of the 21st century. We tested hypotheses that both the level of wild boar populations and rate of the increase in their numbers in Poland in the years 1999−2014 were dependent on some landscape factors, i.e. forest cover, crop field size and maize occurrence. Hunting bag was used as an index of wild boar abundance. The mean hunting bag of this species in the initial and final part of the study period was positively related to the forest cover and the mean size of farms (as an index of crop field size). In the final years also the occurrence of maize showed a positive effect (tab.). However, the index of wild boar bag growth rate decreased with the forest cover and the farm size. Higher increase in wild boar abundance occurred in regions characterized by lower forests share and fragmented crop fields, where the density of investigated species were lower than in regions with the mosaic of forests and large crop fields. The occurrence of maize significantly affected the growth rate index only in north−eastern part of the country (fig.). Our analysis showed that some evolution in wild boar – landscape relations took place in the recent period. Such changes may lead to an increase in conflicts with agricultural economy caused by this species.

Opis:
There are three native and two introduced ruminant species from deer family (Cervidae) living in wild in Poland. The native species (moose Alces alces, red deer Cervus elaphus and roe deer Capreolus capreolus) live also in the Kampinoski National Park, one of the greatest national parks in Poland, that consists of many different habitats such as various types of forest, swamps, meadows and also agricultural areas. Because of protection of this area by Polish and European law, the number of wild ruminants is high (about 350 mooses, 150 red deer and 2500 roe deer). The study was conducted in order to examine the composition of internal parasites of deer living in the Kam− pinoski National Park and to determine their frequency depending on the host species. From September 2014 to April 2015, 343 fecal samples (73 red deer, 133 moose and 137 roe deer) were collected. Standard flotation (using sodium chloride aqueous solution) and sedimentation methods were used, as well as Vajda method (to find expected larvae of lung−inhabiting nematodes). Coccidia from Eimeria genus, three species of trematodes, tapeworms from Moniezia genus, and various nematodes (families Trichostrongylidae and Protostrongylidae, genus Strongyloides, Nematodirus, Trichuris and Aonchotheca) were detected. Nematodes from Trichostrongylidae family have occurred the most frequent in all investigated deer species with the prevalence of 72.2% in moose, 52.1% in red deer and 48.9% in roe deer. Differences among hosts were statistically significant. The prevalence of other invasions has turned out much lower and without statistically significant differences between hosts, except from trematodes. The prevalence of all internal parasite invasions is high in all investigated deer species with the value 83.5%, 79.5% and 60.0% in moose, red deer and roe deer respectively. This high prevalence of parasitic infections is typical for wild ruminants and could be considered as a potential risk for domestic ruminants, because of similarity of the parasitofauna and possible migration of deer, particularly mooses.

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:
There has been an increase in the consumption of the game meat in Europe. Most of the venison products is consumed in West Europe and Scandinavia. Poland belongs to the states, in which the consumption of venison is on the lowest level (0.08 kg/person). We performed a strategic analysis of the venison market in Poland based on the data obtained by direct interviews. The research was carried out in 2015−2017 period among 39 specialists in the field of hunting and participants of the venison market in Poland. Kendall W concordance index was used to measure the compliance of the experts’ opinions. During the study 48 variants of responses were obtained, and average factor ratings were calculated based on the points assigned by the respondents. The advantages include product characteristics, quality and veterinary supervision over the acquisition and processing of the raw material. Growing supply as well as the current hunting traditions in the country have a stimulating effect. In the area of weaknesses, the most important was information and promotion campaign neglected by the last decades. The high price of the final products offered is a factor strongly limiting the consumption of venison in Poland. High and growing public awareness of the need for healthy nutrition is a opportunity for the sector. According to the respondents, the limitation on the consumption of venison is affected by the fear of being infected with zoonoses and doubts about the sanitary and hygienic state of the raw material. The results of the SWOT/TOWS analysis indicate that the most appropriate direction is to emphasize the strengths of the sector and use the opportunities that arise, which is the offensive strategy focused on market development. The significance of the sector’s weaknesses and the awareness of the presence of many threats in the external environment should be an impulse for undertaking a multifaceted discussion and cooperation of entities operating in the industry.

Due to the fact that game animals in Poland over the last hundred years or so have been subject to statistical registration of their abundance and exploitation level, the history of animal species threatened by extinction, i.e. hare, partridge, capercaillie and black grouse and red deer, roe deer, wild boar, fox and beaver in the peak of their population success has been described. Attempt was made to establish the cause of the permanent negative or positive abundance dynamics for these species throughout the country. In addition, a forecast for the future development of these species was formulated.
