Opis:
In the era of sustainable and multifunctional forestry, special efforts should be made to designate areas having the status of (multi)functional forest areas (MFA) and to include them in a special development plans. Their operational goals should be: to increase the acreage, to prevent further fragmentation and to preserve the spatial communication between them. Only such an approach will ensure the relative stability of ecosystems and their protection against anthropogenic degradation. Determining the MFA boundaries would certainly facilitate their space management as well as planning and furnishing activities. People responsible for given spatial units would also be able to determine parities of activities and develop optimal solutions in terms of land development, including the socio−economic development of the region. The concept of MFA delimitation and strengthening is consistent with the EU sustainable development strategy, whose provisions refer to the creation of large−scale natural functional areas. The paper objectives was to discuss the legal status of spatial planning in relation to forests and to propose MFA distinguishing and developing regional operational programs for them. It is urgent and necessary to consider the authorities responsible for forest management (relevant units of the State Forests) as authorized to comment on drafts of conditions and directions of spatial development of municipalities or local and regional spatial development plans. It may improve the effectiveness of spatial planning as one of the instruments for shaping forest resources and forest space in accordance with the principles of permanently sustainable forest management. In the study of conditions and directions of spatial development of the commune, the description of the actual state of the forest space as well as the directions and principles of its shaping should be carried out in a specific standard, in consultation with all units responsible for forest management. Distinguishing Forest Functional Areas may impact the optimization of the costs of forest management and nature protection, because after assigning dominant functions to the distinguished areas, directing financial resources to defined functioning goals will be easier both at the planning stage and during implementation. Verification of the results obtained will also be easier and more transparent. An equally important effect will be to indicate potential conflicts between different expectations from forest management. The characteristics of functional forest areas together with recommendations and suggestions for furnishing works should be provided by Regional Operational Programs, including in their content the assumptions of the region’s spatial development policy, valorization of the forest and assessment of its stability, assumptions for activities related to nature protection and water management, characteristics of climate conditions, optimization of the road network, fire protection, tourist development and forest education, characteristics of the state of forest resources and forecasts of the development of wood resources. An excellent source of information for that purpose is the Forest Data Bank.

Opis:
The paper presents the results of the investigation of the tree crown defoliation in different Kraft’s classes irrespective of damage zone, age class and forest site type. Biosocial position turned out to be itself a decisive factor influencing the significance of the differences in the mean defoliation of the crowns.

Opis:
In years 2002 and 2003, pairs of test plots were established in pine stands of the 3rd and 4th age classes of selected forest divisions. The crown condition of 25 trees from the main stand was assessed on each plot employing the so called stand method. Damage indices were calculated for each test plot, which were used to assign individual stands to the appropriate damage zone. The presence or lack of statistically significant differences of damage indices was checked and this was referred to the membership of individual stand pairs in damage zones. The proportions of damage zones determined according to two divisions for the 3rd, 4th and, jointly, for the 3rd and 4th age classes in both years of observations were compared.
