The purpose of the paper was to determine the impact of the most popular form of recreation and tourism (i.e. walking) on the environment in selected forests that were made available by the means of educational trails. The research was carried out in south−eastern Poland, in the forest reserves Bór (RB) and Polanki (RP) as well as in the economic forests of the Kołaczyce (NK) and Brzozów (NB) forest...
Lasy pełnią niezwykle ważną rolę w procesie łagodzenia zmian klimatu pochłaniając dwutlenek węgla. Same są bardzo wrażliwe na zmiany warunków klimatycznych. W miarę wzrostu temperatury lasu na kuli ziemskiej mogą zacząć wyzwalać więcej węgla, niż pochłaniać. Wartość ekonomiczna lasów w Europie spadnie o 14 do 50% z powodu zmian klimatu. Pogarszający się stan polskich lasów będący efektem ocieplenia...
The study tested the following hypotheses: the mortality of invertebrate fauna is higher (1) on wide trails than on narrow ones, (2) on sections near the entrance to the forest than on the parts located within the forest, and (3) during the weekend than during the workdays. To assess the mortality of epigeic fauna trampled on hiking trails, the most frequented trails in the Chojnów Forest District...
Hydrological processes in forested areas such as runoff and erosion after heavy rainfalls are sensitive to changes in land surface properties that can be significantly modified by fire. Rainfall−runoff events recorded in a small forested catchment in Calabria (southern Italy), of area of 1.36 hectare, in the period of 2014−2015, were analyzed to check differences in lag time of direct runoff, i.e...
Wopracowaniu podjęto temat oceny podatności lasówWielkopolskiego Parku Narodowego na degradację w wyniku działalności turystycznej. Wyznaczono czynniki kształtujące wrażliwość drzewostanów na degradację: typ siedliskowy lasu, stan siedliska, dominujące gatunki drzew, ich wiek, procentowy udział jednego gatunku w drzewostanie, wilgotność gleb, powierzchniową budowę geologiczną oraz spadki terenu. Analiza...
