The data on the distribution and number of the capercaillie Tetrao urogallus in Poland for the period from the end of the 20th century up to 2017−2018 is presented. The capercaillie is a sedentary forest grouse living in old mountain forests and within the boreal zone. Since more than a century, the decrease in the numbers of the species has been observed, interlinked with the extinction of isolated...
Data on sex structure and growth of the population is crucial for proper game management. Camera traps, which are of reasonably low cost, but very efficient, can potentially measure the aforementioned parameters. The paper objectives was to assess the share of bucks, does and calves in red deer Cervus elaphus population in the area of the Białowieża Forest. Two methods were used: camera traps and...
Effects of ungulate pressure on the development of young generation of trees is one of the most important issues in ecology and forestry. Ungulate pressure influence on the development of natural regeneration has been also reported from several national parks. Our study on the effects of ungulate browsing on the young generation of trees was conducted on more than 500 sample plots controlled during...
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 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...
The objective of this paper is to analyse the forest habitat selection by Capercaillie in Polish part of the Western Carpathians. The study was carried out in the Ujsoły Forest District located in the Beskid Żywiecki Mountains in years 2002−2004. Habitats were investigated with regard to the forest types, age classes of the main tree species, canopy closure and altitude. We established 28 linear transects...
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...
