Opis:
The paper provides the results of the subsequent forest management plans conducted for Forest Districts lying on the grounds of the Notecka Primeval Forest. The objective of the studies was to define the trends of changes of indicators used in the assessment of the state of forests and forest management. The obtained results refer to the longer period of time (44 years) and account for important changes in the structure and functioning of the Notecka Primeval Forest.

Opis:
The paper focuses on the characterisation of forest resources and harvesting, sale and distribution of roundwood for woodworking industry, wood−derivative board production plants and pulp and paper indus−try in the Notecka Forest. The age and species structure of stands indicates that the analysed forest complex is and in the future can be an important supplier of timber for sawmills and pulp and paper mills, especially for the Wielkopolska region. The roundwood offered is of an ever more higher quality. A regular increase in proportion of trees in older age classes has caused that the Notecka Forest becomes a source of valuable timber for the sawmill and plywood industries. However, the long−term forms of cooperation between large sawmills and the State Forests Holding have to be perfected.

Opis:
The objective of the studies was to assess the bearing capacity of macadam forest roads made from ungraded crushed stone and two−layered macadam depending on earth−water conditions of the subgrade. The effect of the synthetic reinforcement of natural subgrade on the bearing capacity was also examined. Deflection in the road pavement after a two−year period of exploitation was assessed. The size of deflection was compared with the deflection module and the type of the subgrade and materials used for road construction were analysed

Opis:
The development of the transportation network brings both benefits and threats. Much attention is paid to soil contamination with trace elements, difficulties in animal migration, noise propagation or synanthropisation of the vegetation cover. This paper deals with the effect of provincial road No. 150 on inventory characteristics of neighboring Scots pine stands in the Notecka Forest (western Poland) – one of the larger forest complexes in Europe. Twelve rectangular experimental sites were established perpendicular to the road axis, called belt transects. Each transect consisted of 3−4 plots located at different distances from the pavement edge (fig.). Measurements and estimations were recorded for the plots. Values from all belt transects were approximated within plots at the same distance from the road and then compared using statistical methods. Observations were conducted in Scots pine stands growing on fresh coniferous forest (Bśw) and fresh mixed coniferous forest (BMśw) sites. Reduced stand density that resulted in decreased basal area, volume and growth rates were observed in the immediate vicinity of the road compared to the forest interior. Individual trees were thicker, but more often burdened with defects decreasing timber value. Any considerable effect of the road on tree height wasn't observed. The above mentioned changes were more evident in poorer habitat conditions, while the location in relation to the road had no significant effect. Modified lighting conditions are probably the main cause of these changes. At the edge of Scots pine stands in the Notecka Forest, a unique ecotone has formed under the influence of the provincial road.
