The aim of the research was to determine the frequency of horse recreation in the forests and the awareness of threats resulting from this kind of activity for the forest ecosystem. Horse recreational activities were analyzed in terms of gender, age, education, place of residence, and occupational status. The research used an original questionnaire and was conducted in 2016 among 1203 inhabitants...
Climate change, which was particularly marked at the turn of the 20th and 21st centuries, was accompanied by unfavourable weather phenomena. One of whose effects cannot be prevented is hurricane. Much of the most devastating storms (e.g. Kyrill in January 2007, Carmen in November 2010), which crossed over Poland, was associated with low pressure systems. The occurrence of high wind speeds in the cold...
There are many serious pests in forest nurseries, which can be killed by entomopathogenic nematodes (EPNs) applied to soil. The paper presents a method of biological control, which is appropriate for destroying harmful insects, and is an alternative to chemicals−based approach. Both, the rules and technical conditions concerning the application of biological preparations for insects control are discussed...
The diversity and sustainability of species composition are important topic of forest research. The possibility to observe the coexistence of tree species in a given forest patch and their succession in the next generation is limited because there are few forests unaffected by management activities. For this reason, the study was conducted in the oldest part of the Białowieża National Park, called...
This study analyses the interdisciplinary issue of the objective of legal provisions regarding the four principles of forest management listed in the Act on Forests and their significance for the common welfare and public health in Poland. The common welfare consists of the general determinants necessary for the integral development of people and society, and these determinants include public health,...
Mushrooms are traditionally used in folk medicine in Slavic and Asian countries, especially in traditional Chinese medicine. According to the contemporary scientific research wild−growing mushrooms contain many secondary metabolites of medicinal potential. These compounds were isolated both from mushroom fruiting bodies and mycelium. Many of these bioactive substances exhibit antibacterial, anti−oxidative,...
Extreme weather events such as hurricanes, floods or fires become more and more common phenomena in Europe. In August 2017, strong wind accompanied by heavy thunderstorms caused severe damage over the large area in central and western Poland. According to rapid damage assessment prepared by the State Forests authorities a few days after the windthrow, ca 79.7 thousand hectares of forest was damaged...
OpenStreetMap (OSM) is a collaborative project covering the whole World with topographic data. Data are edited by volunteer users on the basis of satellite images, ortophotomaps and GPS traces, therefore are of diversified quality, especially completeness and positional accuracy. The aim of this study was to evaluate the usability of OSM forest data for Poland. We proved that positional accuracy,...
Forest area in Poland is annually evaluated as a part of public statistics research. However, this information is based on land use resulting from Land and Property Register (LPR). Delays in the reclassification of afforested land, as well as the natural expansion of trees on abandoned agricultural lands, observed over the last decades, caused that information from LPR becomes unreliable. In many...
The article presents the results of questionnaire survey, which aimed to determine social preferences in relation to running as a form of active leisure time in the forests. In 2016 the survey covered 346 people over 18 years of age. As a research tool we used an internet questionnaire, which included questions about such issues as: the frequency of running in the forest, the preferred season and...
The article presents the results of a questionnaire survey that aimed at determining social preferences in relation to running as an active form of leisure in the forests. In 2016 the internet survey covered 346 people living in Poland, and 294 people from the Czech Republic, interested in running and jogging. The questionnaire included questions such as: the frequency of running events in the forest...
Cavities are important, natural components of forest ecosystems, conditioning the high level of biodiversity. They are formed either as a result of a natural process of wood decay caused by fungi or as excavations made by woodpeckers Picidae. Distribution and density of cavity trees are regionally diversified and dependent on species composition and age of the stands as well as the management way...
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...
