    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:
    The article is related to recreational use of forests, a dynamically growing sector of forest exploita− tion complying with the European model of multifunctional forestry. The study examined the relation between selected forestry operations performed in forests and the level of their recre− ational usefulness (recreational potential), and separately between the type of forest−hold and the dominant function of forest versus its usefulness for recreation. The study was carried out in south−eastern Poland, in suburban forests of Rzeszów. Recreational potential was determined with the use of method commonly applied in Poland, based on assessment of several features of tree stands i.e. habitat moisture, age of tree stands, inclination of the terrain, stand density, presence of undergrowth and underbrush, soil cover, species composition of the stand. The rela− tionships were examined with chi−squared test and their strength was assessed with Cramér V index. Tree stands with recreational value account for nearly 72% of the relevant forest area. Mean recreational capacity of the forests amounted to 2.19 man−hour/ha/day. The results show statistically significant effect of forest management in recreational usefulness of tree stands. In the case of forestry operations and type of forest−hold, the relationship is weak, but moderate for forest function. The stands with the largest recreational usefulness where those in which lumber is acquired from small felling sites (92% of these were useful for recreation), or those located in protection forests and fulfilling water protection functions (not to be confused with protection of water intakes, i.e. special forests). Protection forests were found with twice as many recre− ationally useful stands (60%) than commercial forests (32%). Similarly, water−protecting forests were twice as useful for recreation (78%) as forests protecting urban areas (35%) and forests damaged by industry (37%). The main factors reducing recreational usefulness of forests include dense undergrowth and underbrush (40% of land cover). The study identifies the elements of commercial forestry resulting in greater recreational usefulness of forests; hence it is possible to designate tree stands, which can be additionally developed for tourism related purposes without a need to modify the existing principles of forest management. On the other hand, in forests accessible for leisure, foresters can enhance the increase in recreational potential of forests by conducting planned commercial operations.
