    camera trap
    Opis:
    On the 21st June 2021 at 10:17 PM, one lynx individual was recorded in the area of the Wyszków Forest District by a camera trap (Browning Spec Ops Advantage). The device was set up as part of a study on the behaviour of predators at the crossing of forest roads. The camera trap was one of nine devices operating in the area from June 1st, 2019 to September 30th, 2021 (853 working days). The Wyszków Forest District is located in the Biała Forest between two known lynx populations in the Kampinos Forest and the Eastern Baltic population. This record is the first report of a lynx sighting in the Biała Forest north of the Bug river.

    Opis:
    In some parts of the country, the moose density is so high that it is causing serious damage to forestry and agriculture. In addition, collisions between motor vehicles and moose crossing roads or railroad tracks are becoming more frequent. The number of moose in Poland is expected to increase. So far, there have been considerations to allow hunting of these animals again, which would theoretically reduce economic losses, support forest management and increase the safety of travelers. However, recent research on moose populations suggests that ongoing climate change is affecting their habitats and physiological condition to such an extent that there could soon be a slowdown in population growth and a risk of collapse. The increasing population of large predators in forest ecosystems may also lead to increased mortality, so the current growth rate of the moose population could be directly disrupted in the near future. Other ecological aspects of the moose population may facilitate the management of this species. There are increasingly advanced and effective methods based on population trends or biological indicators that can be used to monitor the status of the population more easily and effectively. In order to ensure sustainable management of the native moose population in Poland, it is crucial to update knowledge about the ecological aspects affecting the population and its dynamics, which have been ignored or not sufficiently taken into account so far.

    Opis:
    The aim of the study was to evaluate arguments for hunting and its impact on forest management and conservation in national parks as well as areas directly adjacent to them. The issue was examined using the example of the Magura National Park (MNP) for which data on the number of deer and predatory mammals included in the statistical yearbooks for 2013–2014 were available. The quality and size of the food sources provided by this type of forest habitat were evaluated using data obtained from the literature. We also included data on the dietary habits of wolves and lynxes as well as their impact on the number of large ungulates in our analysis. The maximum carrying capacity of forest stands in the Magura National Park was determined to be 789 deer units (dear unit = 1 red deer or 0,3 elk or 5 roe deer), whereas in fact in 2014, the abundance of ungulates reached a total of 1230 deer units. Our analysis evaluating the impact of wolf and lynx populations on ungulates in the area showed that these predators can kill up to 212 deer per year (140 individuals by wolves and 72 by lynxes). The growth in deer population, however, varies from 25,8% to 27,7%, which in the MNP amounts to 258–277 new born individuals per year, meaning that the wolf and lynx populations in the MNP are not able to prevent the number of deer from growing. The current population of ungulates (1230 deer units ) having reached a density of 6,6 deer units/km2 exceeds the capacity of the MNP and thus poses a real threat to maintaining both, the nature of the park and the adjacent stands. This article shows that the natural maintenance of balance in the predator-prey relationship is unlikely under these conditions and failure to allow for anthropogenic interference to regulate the number of ungulates in protected areas may result in an increase in the density of their population. Potential destruction of other valuable assets such as forest habitats may consequently follow.
