Opis:
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.

Opis:
Paper discusses the influence of site quality on self−thinning process in silver birch stands growing on abandoned farmlands in Mazowieckie region (central Poland). Number of trees in a stand decreases with increasing age. The better the site (the higher site index value), the higher number of trees can be observed. However at the age of 10 difference between sites of various quality (site index) become insignificant. There is no need to include site index into the self−thinning models for young silver birch stands.

Opis:
The objective of the study was to analyse the site index (SI) of Douglas fir (Pseudotsuga menziesii) stands in relation to the forest habitat type, soil type and relief characteristics. We utilised infor− mation available in the Information System of the State Forests in Poland that included selected parameters describing habitat conditions and dendrometric characteristics of Douglas fir stands. In total, processed data referred to 863 stands with a total area of 1,644.45 ha. As the SI distribution was not consistent with the normal one (Shapiro−Wilk test, p <0.0001) we applied Kruskal−Wallis or Mann−Whitney tests to assess the significance of observed differences. Site index of surveyed stands ranged from 19.9 to 47.8 m, 32.6 m on average (standard deviation of 3.3 m). Douglas fir in northern and southern Poland characterized by higher SI than in western and south−western part of the country (HK−W=83.5; p<<0.001; fig. 2). Forest habitat type significantly distinguished analysed stands (HK−W=30.1; p<<0.001). The highest SI values were observed for mixed deciduous habitats (fig. 3). For more fertile fresh deciduous habitats Douglas fir achieved slightly lower site index, while the least fertile mixed coniferous habitats are characterized by significantly lower SI. Habitat moisture variant had no significant effect on the average SI values (HK−W=2.6; p=0.269). The highest values were found in strongly fresh habitats (32.8 ±4.1 m), while the lowest in the humid variant (31.7 ±3.4 m). We found significant influence of soil type (HK−W=23.2, p<0.001) even though the average SI values for each category were relatively similar (fig. 4). The highest values were observed for Cambisols (33.3 ±3.7 m), while the lowest for Arenosols (32.1 ±3.0 m). Particle size distribution is an important factor for Douglas fir site index (tab.). We found that the heavier material (the higher the content of silt and clay), the significantly higher SI values (HK−W=16.9; p=0.001). Mean SI for stands growing on former farmlands (32.0 ±3.3 m) and on forest areas (32.7 ±3.3 m) were not significantly different (ZM−W=1.73; p=0.084). There was no significant effect of the relief forms on site index surveyed Douglas fir stands apart from the fact that stands growing on slopes are characterized by significantly higher SI (ZM−W=1.99; p=0.047).

Opis:
The work studied the effects of site conditions on the amount of deadwood (DW) in managed forests in south−western Poland. Measurements included standing dead trees, snags with a diameter at breast height of at least 7 cm, and lying deadwood (logs, branches, uprooted trees, etc.) with a diameter at the thicker end of at least 10 cm. The study excluded snags and deadwood pieces with a diameter of less than 7 cm as well as stumps. Site conditions are presented according to the Polish site classification system taking into account both site fertility and water abundance. With respect of the fertility gradient, sites are classified as dystrophic, oligotrophic, mesotrophic, and eutrophic. In terms of water abundance, there are two types of sites: mesic (low or very low contribution of groundwater, rainwater, and floodwater, with an approximate springtime water table depth of more than 1.8 m) and moist (moderate or considerable contribution of groundwater, rainwater, and floodwater, with an approximate springtime water table depth of 0.5−1.8 m). We analyzed data from 2522 sampling plots with area ranging from 50 to 500 m² and depending on forest stand age. The plots were established in forest stands older than 21 years old. The predominant tree species in the study area were Pinus sylvestris, Quercus robur, Quercus petraea, Betula pendula, Fagus sylvatica, Alnus glutinosa, Fraxinus excelsior and Picea abies. In a separate analysis of data from 233 sampling plots, we studied the relationship between DW volume and the site index evaluated using a five−level classification (level I denotes sites with the highest productive capacity). Forest stands aged >80 years with the dominance of Pinus sylvestris were studied. The study showed a significant influence of site conditions on the DW volume in managed forests. Forest stands exhibiting better site conditions not only provided more timber, but also contributed with a greater amount of deadwood to the ecosystem. Forest stands with a site index of I contained as much as 4.9 m³ of DW/ha, while stands with a site index of III only 2.4 m³ of DW/ha. In terms of the 8 studied site types, it was also found that the average volume of DW increased with site fertility. The lowest volume of DW occurred on very nutrient−poor and mesic sites (0.6 m³/ha). In contrast, nutrient−rich and moist sites contained 15 times as much DW (9.5 m³/ha). Of paramount importance was water abundance. The volume of DW on moist sites was on average by 2.2−4.5 m³/ha higher than on mesicsites with the same fertility.

Opis:
This article describes use of the Generalized Algebraic Difference Approach for derivation of generic dynamic site equations. The generic equations are useful in situations of unspecific expectations with regards to the final model form where one wants to test simultaneously in a single fitting many various models and assumptions about the modeled processes. Equations derived in this work are extremely flexible with various patterns of polymorphisms and asymptotes. Even thought in principle the generic equations have more parameters, those derived with methodology proposed here are very parsimonious.

Opis:
The objective of the study was to determine the impact of selected soil properties on site index of oak (Quercus sp.) stands in the Międzyrzec Forest District (eastern Poland). We utilised data from the soil−habitat survey, which provided information about physical and chemical properties of soils and stand descriptions for 21 oak stands (tab. 1). The collected data served to determine site index (SI), defined as the stand top−height at the age of 100, and soil trophic index (SIG) that is a synthetic measure of the soil fertility. For SI and SIG distributions met the criteria of the normal distribution (Shapiro−Wilk test p−values equalled 0.118 and 0.297, respectively), we applied one−way analysis of variance, t−test and correlation analysis to determine the influence of the forest habitat type and moisture as well as soil properties and fertility measures on the site index of analysed oaks. The SI of investigated oaks ranged from 23.2 to 29.3 m, 26.5 m on average (tab. 2). It was significantly dependent on the site type (F=6.913, p=0.006) with the lowest values on oligotrophic habitat and the highest – on eutrophic one. No effect of habitat moisture content and soil type was found (t=–0.408, p=0.688 and F=2.599, p=0.076, respectively). The SIG values ranged from 20 to 36, with the average of 29.5 (tab. 2). Similarly to the site index, we found significant impact of the forest habitat type (F=5.384, p=0.015) on SIG values. Soil fertility and physical properties significantly influenced site index of the analysed oaks (fig.). We found positive correlation between SI and SIG values (r=0.566, p=0.007) as well as between SI and clay content (r=0.454, p=0.037). Chemical properties of the soils under studied stands seem to have less profound effect on site index of oak. The highest, but insignificant, correlations were found for recalculated acidity (r=–0.420, p=0.056) and magnesium content (r=0.400, p=0.071).

Opis:
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.
