Opis:
The paper presents the ideas of sustainable development with regard to the specific forest issues and management of its resources. We consider two main directions of forest use, which have the greatest impact on the condition of forest environment, i.e. logging and recreational use of the forest. This confrontation shows how effective the instruments of sustainable development are in collision with, on the one hand, the pragmatic−economic issue of profitability and a specific profit from logging, and, on the other hand, with the autotelic tourist exploration of the forest. The aim of the paper was to discuss selected aspects of sustainable forest use with regard to the sustainable development program and to identify problems, which modern forest management (forest utilisation) faces as a result of society’s expectations and the possibilities of today’s forestry in Poland. The example of Poland shows that there is a full understanding of the need to preserve the forests in the landscape, which was reflected in the form of legal acts and adopted international regulations for sustainable forest management (most forests in Poland have PEFC and FSC certificates). However, considering forest use as one of the main branches of forest management, there is still a large deficit of pro−ecological logging technologies in Poland, especially from difficult mountain areas (about 150 cableways missing), which is largely due to economic factor. The other problem of sustainable forest use in Poland is still low social awareness of the consequences of negative human impact on the forest ecosystem, which is manifested, i.e. littering in forests. Garbage is left both during leisure in forest as well as brought in larger quantities creating so−called wild dumping sites frequently containing also hazardous waste. Another problem of contemporary forest use is the maintenance of durability of forest ecosystems in recreational and tourist areas, especially protected areas, and above all in national parks, most of which in Poland have a forest character. The scale of threat to forest sustainability is incomparably higher here than in economic forests, which results from the large number of visitors in the national parks.

Opis:
The strictly protected Swiss stone pine (Pinus cembra) is one of the most valuable elements of Polish dendroflora, naturally distributed only in the Tatra Mts. (S Poland/N Slovakia). In 2008−2009 intense P. cembra dieback was recorded in Slovak part of the mountains, especially in the localities adjacent to the Norway spruce stands affected by bark beetle Ips typographus outbreak. The mortality of individual P. cembra trees was observed in 2012 also in the Polish part, next to the area of the bark beetle outbreak on spruce. In the winter 2017/2018 the survey was carried out in order to assess the intensity of P. cembra dieback and the impact of the bark and wood boring insects on this process. In Suchej Wody Valley, where all P. cembra trees were precisely mapped in 2004−2008, health status of all previously living trees were checked again. In the summer 2018 bark samples from 50 dying or dead standing trees attacked by those insects and distributed over the whole Tatra National Park area were collected in order to define their species composition based on the gallery systems and (if possible) beetles or their fragments. Only 4 out of 439 checked trees (<1%) were recorded as dead. The bark samples were collected mostly from dead trees (88%), and in some cases from dying ones. The presence of insects belonging to 10 taxa (Curculionidae, Scolytinae – 6, Molytinae – 1; Cerambycidae – 2) was detected. Most of them is known as infesting Norway spruce. The most frequently (on the entire tree level) occurring were Cerambycids Tetropium sp. (56%) and Rhagium sp. (36%), as well as I. typographus (52%), contrarily to the species known as living on or preferring P. cembra (I. amitinus, Pissodes pini, Polygraphus sp.). The dieback of Swiss stone pine seems to be a slow process, in which the bark and wood boring insects (I. typographus, I. amitinus, Tetropium sp., Pityogenes chalcographus, Polygraphus sp.) are involved, but rather as secondary factor affecting weakened trees. However, the possible impact of the bark beetle outbreak in neighbouring spruce stands, expressed by high I. typographus frequency, should be also taken in consideration.
