    Opis:
    Paper emphasises the positive impact of the forest management planning on the condition of Polish forests after World War II. Attention was drawn to the solutions in the forest law supporting sustainable forest management. General views on modern forest management planning of three distinguished scientists, specialists in forest ecosystem functioning, Aleksander Sokołowski, Eugeniusz Bernadzki and Andrzej Szujecki were presented.

    Opis:
    Since several years already, a massive infestation of bark beetle has taken place in the Białowieża Forest, decimating a local Norway spruce population. In consequence, many open areas appeared, practically deprived of trees and other forest vegetation. The existence of such areas has a very negative impact on multiple values of the Białowieża Forest: natural, social, economical and landscape−aesthetic values. The local forest administration prepared a strategy aimed at active restoration of diverse woodland communities typical for the Białowieża Forest in all places, where bark beetle infestation wiped up the spruce stands. Those plans were criticized by representatives of the environmental organizations who blamed the foresters for transforming the Białowieża Forest into ‘plantation’ and claiming that such measures are inconsistent with the existing forest management and protection plan. The postulate of environmentalists is that the recovery of woodland communities should proceed completely naturally. Taking into account the above mentioned controversies, in this paper we examine the issue of natural regeneration in the Białowieża Forest in detail. In particular, we try to determine to which extent this method of forest reproduction enables re−establishment of compositionally diverse woodland communities, distinguished by a high level of biological diversity and able to provide a wide range of commodities and benefits important for today’s society. Based on an extensive literature review we show that a combination of different (abiotic and biotic) factors, influencing establishment and subsequent growth of seedlings and saplings in the Białowieża Forest has long been strongly unfavorable for many tree species. In this regard, one should particularly emphasize the negative role of large herbivores, especially red deer, which is present in the Białowieża Forest since the end of 19th century, when it became a private hunting ground for Russian tzars. The devastating effect of deer browsing on natural regeneration is a well−documented phenomenon and widely recognized problem in the forestry practice. The fencing of young forest generation against game pressure is an indispensable measure, needed to secure the continuous existence of several tree species (first of all those palatable and vulnerable to browsing). Very strong arguments for an active approach to the described problem delivers also a long−term study on natural forest dynamics conducted since 1936. It shows that under conditions of strict protection the regeneration capacity of the Białowieża tree species is very variable. These differences lead to the compositional simplification and impoverishment of many tree stands, with numerous negative consequences for local biodiversity. We underline that an active management strategy is a basic prerequisite for maintaining a diverse character of the Białowieża stands and their ability to provide all important ecosystem services on a sustainable basis. Such a strategy should include, beside of the phase of establishment, also the subsequent developmental stages of new forest generations. The general goal of such a strategy should be to secure a possibly high diversity of tree composition and to enable the development of tree species representing a full range of life−history strategies and playing different successional roles: from typical pioneer species, through intermediate, to climax species.

    Opis:
    Underdevelopment of rural areas, in spite of many advantages of living there, causes the need of searching for the new directions of the development of these areas. Due to the interaction between the rural area and forest, we can expect that the development of one area will be an opportunity for the other one. This is possible due to the implementation of sustainable development idea, taking place in current transformation of forest management and agriculture. The present policy of rural development in Poland is a significant tool for implementation of forestry-related activities. Therefore, the purpose of this article is to present that the rational forest management can be an instrument of influence on the development of rural areas. In the article, besides the results of a survey that was carried out, Polish and foreign literature, as well as statistical data were used. The empirical material that forms the basis of this work was collected during surveys conducted in 2011 on a sample of 21 representatives of managerial staff from the Regional Directorate of State Forests in Olsztyn. The results of a survey indicate that in the areas where we can find real and economically measurable effects of the implications of the rational forest management principles there are mainly: •• a reduction of unemployment rate by creating jobs directly in forest management, as permanent and seasonal work; •• development of forestry-connected sectors and owing to the fact growth of employment rate in the region (paper industry, furniture, woodworking); •• economic benefits and maintaining traditions associated with gathering undergrowth goods (fruit, mushrooms etc.); •• stable and reliable income to government budgets from forest taxes; •• collaboration with local institutions, associations, institutions in order to co-create strategies, develop plans and environmental awareness; •• support to hunting economy; •• enhance the advantages of the region in the context of the tourist and recreation services. The impact of the forest management is not limited to the described benefits that can be economically measured. We should not forget about a number of other advantages which are delivered for the society indirectly or which are difficult in the valuation, eg. the beauty of the landscape or clean air. In that case, it is worth perceiving a forest not only through the prism of a large area, but also as an economic sector strongly related to the rural development.

    In this paper it has been established that multifunctional forests in Poland are not subject to regulation. It has been proposed that all multifunctional forests be divided into two categories: I – forests with exceptional (extraordinary) values and functions and II – other multifunctional forests.

    Opis:
    Modern multifunctional forest management needs indicators showing the state of forest environment. Commonly used solution is monitoring of the abundance of species with specific environmental requirements. This paper analyses the possibility of use of the biggest European woodpecker (Dryocopus martius) as forest management quality indicator. The black woodpecker resides in all types of forest sites. The species prefers big thick trees as a nest trees, its cavities were mainly made in birches Betula sp. in Western and Southern Europe, Scots pines Pinus sylvestris in Middle and Eastern Europe and aspens Populus tremula in Northern Europe. The black woodpecker, excavating large−sized breeding cavities, is defined as a key species due to the creation of breeding sites for large secondary cavity−nesters. Because of the breeding requirements, black woodpecker can also be treated as an umbrella species for organisms associated with old trees. The way of feeding of that species shows a strong connection with the availability of dead wood. The black woodpecker is a sedentary species, which means that it is highly depended on the structure of the forest and quickly responds to changes caused by forest management. Because of the habitat requirements and relationships with other species, as well as the wide geographical range, it is a good indicator species for multifunctional suitable forest management. It can also act as a keystone species for secondary cavity nesters and umbrella species for organisms associated with old, dying trees.
