The aim of the study was to develop a site index model for Scots pine stands in southern Poland describing changes in height growth of stand's upper storey over time. The research material contained the height growth data obtained from an analysis of 189 tree stems. The collected material was used to develop the parameters of six dynamic growth equations which allowed to determine site productivity and predict changes in height growth of stands with age. Statistical criteria for assessing the accuracy of mapping empirical data and biological reasonableness were the basis of selection of the equation that best fits changes in height growth of the examined pine stands with age. The developed model can be used to predict the growth rate and determine the site index for Scots pine stands in southern Poland.

The aim of the study was to investigate the structure of forest site types and of soil types of oak seed stands in Poland. The study was comparatively conducted with reference to sessile (Quercus petraea) and common (Q. robur) oaks. As in Poland the seed stands are established only in stands characterized by favourable both growth parameters and timber quality, it was suspected that the results of the study would enable to indicate optimal sites and soil units for oak breeding in Poland. The study was conducted on the basis of data obtained from the SEMEN database (www.bnl.gov.pl) which were broadened by descriptions of the investigated seed stands found in the Forest Data Bank (www.bdl.lasy.gov.pl). For both oak species, the research was conducted with reference to the two types of seed stands: permanent (WDN) and temporary (GDN). In total, 531 stands of Quercus petraea and 2043 of Q. robur located across whole Poland were investigated in the study. It was found that optimal soils as well as forest site types overlap for both investigated oak species only for fresh broadleaved forest (Lśw). For other forest type sites distinct differences for the oak species were found. The optimum for common oak were expanded towards the wet sites (moist broadleaved forest – Lw, and riparian forest – Lł), while for sessile oak towards semi−fertile mixed broadleaved forest (LMśw). It is interesting that seed stands of both oak species overgrow not only fine−textured soils, but significant share of them (ca. 50% area of Q. petraea and 15% of Q. robur seed stands) occurs on sandy soils (Brunic Arenosols mainly). It proves that Brunic Arenosols constitute forest sites enabling production of broadleaved forests characterized by favourable growth parameters and high timber quality. However, it is possible unless the soil have been podzolized by conifers due to podzolized Brunic Arenosols were rarely represented in the oak seed stands and, if so, the stands were characterized by relatively low site index. It was also stated that on podzolized Brunic Arenosols of fresh mixed coniferous forest (BMśw) admixture of oak should enable reducing negatively impact of conifers on a soil.

Forming of site index class of Scots pine (Pinus sylvestris L.) stands in relation to forest site types (including their moisture variants) and soil units (type/subtype and also – in minor extent – geological genesis of soil parent material) was investigated. The research was conducted in the Bolesławiec, Głogów and Oława forest districts (SW Poland) in 348 Scots pine stands. The values of the pine site index got higher with increasing fertility of soil units and better forest site type, but only when plots of sandy soils where concerned. Site index was found to differ significantly between fresh than moisture forest sites and soil units. The study results demonstrated that on fresh soils of sandy texture site index of Scots pine was distinctly related even to minor differences of site properties that concerned both its moisture and fertility. Scots pine, by height growth, does not fully utilize the great nutrient retention of fine textured soils that concerned both fresh and moisture pedons. Fine textured soils should be designed for eutrophic broadleaved tree species planting only, which would enable to fully utilize the trophic potential of such soils. The relation between the site index and geological genesis of sand forming parent material of soils was found. The differences in pine growth on sands of other genesis were assumed to be a result of different sorting and mineral composition of these materials.

The aim of the study was to determine the impact of land relief on site index and growth parameters (height, diameter, slenderness) of Scots pine (Pinus sylvestris) stands on inland dunes in the Toruń Basin (N Poland). The study was conducted on 150 plots situated on north− and south−facing dune slopes (54 pairs of twin plots) as well as in intra−dune depressions (42 plots). Height and diameter of ten the thickest pines per 0.1 hectare was measured, and next site index as a potential height of a stand at the age of 100 years was calculated. As the results of the used equation, site index was strongly (R²=0.58) negatively biased to age, so the bias was removed using an elaborated regression model. For stands older than ca. 20 years, the clear higher site index values as well as higher heights and diameters were found for intra−dune depressions than for slopes of the two studied aspects. This was explained by the occurrence of much more fertile and moister soils in depressions. The only age class for which the advantage of site index and growth parameters was not stated for depressions was the youngest class (≤20 years old). This was likely caused by the competitive impact on young pines of Calamagrostis epigejos which prefers intra−dune depressions on inland dunes and forms in forest floor usually dense cover in this position. Impact of contrasting slope aspect was clearly related in the study to age of a stand. For the youngest studied age class both site index values as well as heights and diameters were lower on north− than on south−facing slopes. This was explained by the effect of weeds which form more dense cover on slopes of this aspect than on sunny slopes. For older stands; however higher site index values as well as heights and diameters were revealed for north−facing slopes, due to pines likely took advantage of higher moisture of soils occurring in this place. With reference to slenderness, regardless stand age the parameter was regularly the highest for north− than both for south−facing slopes and depressions. Because of the revealed distinct higher productivity of intra−dune depressions in normally dry and poor in nutrients dune landscape, it could be reasonable to use the depressions to introduce admixtures of broadleaved tree species into pine monocultures on inland dunes.
