Opis:
The main objective of the research was to evaluate the incremental response of Douglas fir and Scots pine subjected to strong environmental stress to variable thermal and precipitation conditions. We also attempted to determine periods of tree−ring width reduction caused by strong anthropopressure associated with the activities of nearby industrial plants, which are burdensome for the environment. The studied forest stands are located in the Kędzierzyn Forest District, in Kotlarnia forestry (50°27'59'N, 18°38'42'E) approximately 8 km away from the nitrogen production plants. We used standard methodology applied in the dendrochronological studies with the support of the TSAP−Win, Cofecha, Arstan and Quercus 06.01 softwares. We found that Douglas fir and Scots pine stands growing in the permanently damaged zone due to the adverse effects of industry responded to meteorological conditions in a manner typical of the species. In the study of the relationship between weather and growth, thermal and precipitation conditions were more important in the current year than in the year preceding the increment. A similar distribution of reductions and periods of partial regeneration in both species were also observed. In the same multi−annual period of 1961−1991 deeper reductions of annual increments were observed in Douglas fir (>70%) than in Scots pine (in the range of 50−70%). Conditions, in which trees grew in the Kędzierzyn Forest District, contributed to the decrease in annual increments of both Douglas fir and Scots pine, while the previous species turned out to be a more sensitive one, which had been indicated by other researchers ealier.

Opis:
The objective of the study was to determine the quantitative and valuable potential of wood resources of black locust (Robinia pseudoacacia) and Douglas fir (Pseudotsuga menziesii) in individual regional directorates of the State Forests (RDSFs) in Poland. We used data from the State Forests Information System database (values for the end of 2014) to determine the amount of the resources of the analysed species in forests under the State Forests management. The monetary value of black locust and Douglas fir resources was determined using both the indicator method and on the basis of sales prices of individual assortments. The occurrence, and hence the resources of black locust and Douglas fir in our country are characterized by considerable spatial diversity. Generally speaking, studied tree species are of minor importance in Polish forests as far as area and volume are concerned, but both species can the most often and in the large abundance be found in the western and northern Poland. The average sale price of wood of the tested species varied a lot in individual regional directorates of the State Forests (fig.). In the case of black locust the average sale price ranged from 99 PLN/m3 in RDSF Szczecinek to 151 PLN/m3 in RDSF Krakow, while for Douglas fir the values from 59 PLN/m3 in RDSF Łódź to 277 PLN/m3 in RDSF Katowice were obtained. The total value of black locust timber resources was assessed by the sale price method at PLN 262.4 million, and by the indicator method at PLN 186.4 million. In the case of Douglas fir timber, these values were much higher and amounted to PLN 375.0 and 309.2 million, respectively. The highest value of the studied species stands was noted in the RDSF with the largest amount of their resources.

Opis:
The level of damage to the cell membranes is a sign of aging of the seeds and a decrease in their viability. Conductometric seed testing method indirectly utilizes uncontrolled leakage of ions from seeds with damaged cell membranes to assess their viability. This involves the use of an electrical conductivity of the aqueous solution, in which seeds are soaked. The research was conducted in the years 2011−2014 and aimed at developing the methodology of evaluation of Scots pine and Douglas fir seeds by conductivity test. The aim of the study was to determine the relationship between electrolyte leakage and germination capacity of Scots pine and Douglas fir seeds. 402 samples of Scots pine seed and 90 specimens of Douglas fir seed from all over Poland were tested. The research material was both freshly harvested and stored. Scots pine seeds were obtained in the years 2008−2014, while Douglas fir – 2003−2013 as well as ones stored in the refrigerator for 15 years. Conductivity test and standard seed germination procedure of the analyzed species were used. For both Scots pine and Douglas fir, we noted that, as the electrolyte leakage rate increased, the germination capacity of the seed decreased. So we decided to test whether the vitality of the seeds was determined by means of a conductivity test. The best−fit regression model was determined and the mean expected germination capacity in the viability classes was calculated. 95% confidence intervals for the regression function were also determined. Evaluation of the viability of the seeds by means of the conductometric method is especially useful for seeds requiring a long stratification period (e.g. Douglas fir to determine the potential loss of their vitality. Although the ISTA seed evaluation rules do not require conductivity test for evaluating the seeds of Scots pine and Douglas fir, it may be applicable in situations where it is necessary to perform a rapid assessment of viability before spring sowing.

Opis:
Drewno to priorytetowy surowiec dla przemysłu celulozowego i energetycznego. Źródłem surowcowym są lasy. Powierzchnia lasów w Polsce, z roku na rok, nieustannie wzrasta. Wzrost lesistości od roku 1945 wynosi 8,4%. Przyrost ten jest wynikiem zalesiania gruntów użytkowanych przez rolnictwo i nieużytków [1]. W monografii przedstawiono budowę mikroskopową i makroskopową drewna sosny zwyczajnej Pinus sylvestris L., pochodzącej z czterech wybranych krain przyrodniczoleśnych Polski: Kraina A - Mazowiecko – Podlaska Kraina Przyrodniczo – Leśna (Nadleśnictwo Garwolin), Kraina B - Małopolska Kraina Przyrodniczo – Leśna (Nadleśnictwo Przedbórz), Kraina C - Śląska Kraina Przyrodniczo – Leśna (Nadleśnictwo Kędzierzyn Koźle), Kraina D - Karpacka Kraina Przyrodniczo – Leśna (Nadleśnictwo Piwniczna). Ukazano strukturę mikroskopową jodły pospolitej Abies alba Mill, modrzewia europejskiego Larix decidua Mill. pochodzącego z zabytkowego obiektu wybudowanego w 1860 r., sosny zwyczajnej Pinus sylvestris L. poddanej 5 - letnim wpływom atmosferycznym oraz degradacji biologicznej. Określono przyrosty roczne, biel i twardziel, pęcherze i wycieki żywiczne oraz promienie łykodrzewne. Zaprezentowano właściwości rozpoznawcze wybranych rodzajów drewna iglastego, w szczególności zabarwienie twardzieli, szerokość przyrostów rocznych, udział bielu i twardzieli, obecność przewodów żywicznych, przejście z drewna wczesnego do późnego czy strukturę sęka. Dodatkowo scharakteryzowano takie gatunki drzew, jak sosna zwyczajna Pinus sylvestris L., świerk pospolity Picea abies Karst., modrzew europejski Larix decidua Mill., jodła pospolita Abies alba Mill., daglezja zielona Pseudotsuga menziesii Franco [1-2].
Wood is a basic raw material for paper and pulp industry, and also in power generation. Wood supplies are provided by forests. In Poland, the area of forests continues to increase annually. Since 1945, forest cover has grown by 8.4%. The increment results from afforestation of the land with former agricultural use, and of uncultivated land [1]. In the monograph, the micro- and macroscopic structure of wood from pine Pinus sylvestris L. was presented. The wood originated from four selected nature-forest areas of Poland, namely Area A - Mazowiecko – Podlaska Nature-Forest Area (Garwolin Forest Inspectorate), Area B - Małopolska Nature-Forest Area (Przedbórz Forest Inspectorate), Area C - Śląska Nature-Forest Area (Kędzierzyn Koźle Forest Inspectorate), Area D - Karpacka Nature-Forest Area (Piwniczna Forest Inspectorate). Wood microscopic structure analysis was performed for the following conifer species: silver fir Abies alba Mill, European larch Larix decidua Mill., the wood of which was obtained from a historical structure built in 1860, and pine Pinus sylvestris L., the wood of which was exposed to atmospheric conditions and biological degradation for a 5 – year period. The following features were specified: annual rings, sapwood and heartwood, resin pockets and leaks, and also medullary rays. The distinctive properties of selected coniferous wood species were presented, including heartwood colour, the width of annual rings, sapwood and heartwood content, the occurrence of resin ducts, transition from earlywood to latewood, and also knot structure. Additionally, the characteristics of the wood of the following species were provided: pine Pinus sylvestris L., spruce Picea abies Karst., European larch Larix decidua Mill., silver fir Abies alba Mill., Douglas fir Pseudotsuga menziesii Franco [1-2].

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:
There are no original local yield tables for Douglas fir stands grown in Poland. In the presented study we attempted to answer the question whether it is possible to successfully use the German yield tables for Douglas fir developed by Bergel [1985]. Based on the data from these yield tables we developed the height growth model (site index curves) for Douglas fir in the form of the polymorphic equation with variable asymptotes. This model appeared to be, as expected, far better than the anamorphic model. We applied the elaborated equation for calculation of the site index for 63 randomly selected research plots located on the typical Douglas fir habitat types (fresh mixed broadleaved forest and fresh broadleaved forest) in western Poland. We concluded that the mean site index values are significantly higher in younger stands than in the older ones. To determine the reason for this phenomenon, we tested the resulting model using the published data from the permanent research plots. We found out that the pattern of site index changes with age varies for stands in different age classes. Moreover, we noticed, that regardless the age of the stand, in the recent decades there is the increasing height growth rate, which can be attributed to the change in environmental conditions. On the other hand, the analysis of the other characteristics of the sample plots revealed, that there is no significant relationship between site index values and site and plot location, as well as between the productivity level, expressed by the value of the EN coefficient, and age class, site and location of the stand. Bergel yield tables can be used in Polish conditions taking into account the age−dependency of the site index values.

Since the beginning of XIX century a considerable number of Douglas fir populations from North America were introduced to many European countries. In France, Douglas fir is still going to increase significantly its participation in growing stock and wood harvest. There are also some countries (e.g. the Netherlands), where the interest in breeding and silviculture of Douglas fir have been decreased in last decades. The data from the European literature was collected to show a current volume stock, growth increment, gene resources and qualified seed sources of Douglas fir in the outlook of the future role of the species in European forest economy. A short outlook on the breeding programs of Douglas fir working out in several European countries was also presented.

Paper analyses relationships between radial growth and seven crown−related parameters (crown length, relative length, width, slenderness, projection area and volume as well as single tree space) for ten alien and native tree species growing in 'common garden' conditions in the WULS−SGGW Forest Experimental Station in Rogów (central Poland). Significant correlation was found between 10− and 15−years mean tree−ring width and all analysed crown parameters as well as single tree space for Abies grandis, Abies nordmanniana and, except for crown length and its relative length, for Pinus sylvestris. No relationship was observed between radial increment of Larix decidua, Pseudotsuga menziesii and Quercus rubra and any of analysed crown parameters.

I present dendroclimatological analysis of coniferous tree species growing under the same environmental conditions in the WULS-SGGW Forest Experimental Station in Rogów (51° 49' N, 19° 53' E, ca. 190 m a.s.l). The study focuses on silver fir, European larch, Scots pine and Douglas fir. For each species, tree-ring width and annual sensitivity chronologies were developed for the period 1931–2010. Analysed species show considerable similarity of their radial increment course (GLK up to 67%, the t-value of 3,5–9,5). The relationship obtained for of the influence of climate conditions on radial growth of these species is typical of the relationships reported from other locations in lowland Poland. Late winter and early spring temperature, especially during February-March, is the main factor affecting tree-ring formation. The general relationship demonstrates that this seasonal thermal limitation operates at an inter-regional and interspecific level in determining the growth of coniferous tree species in Poland. Whereas, the dependence of these species on precipitation is much less significant.

Opis:
The history of research on tree species of alien origin began in Germany at the beginning of the nineteenth century, when chancellor Bismarck inspired by information about John Booth – who introduced Douglas fir into Europe – became closely interested in that subject matter (North American trees species were characterised by extraordinary productivity). On 15th June 1880, Bernhard Danckelmann – director of the Forest Academy in Eberswalde – was instructed to work out a detailed scheme of the whole system of forest experimental plots. Adam Schwappach was recruited to Eberswalde in 1886 by Bernhard Danckelmann and was to manage the project. Thanks to that, the forest research institute in Eberswalde has today a one of a kind system of permanent experimental plots including 32 species of alien trees originating mainly from North America (26 species), but also from the Caucasus (1), the Balkans (1) and the Japanese archipelago (4). This paper describes the main objects of research on selected alien species (Pseudotsuga menziesii, Thuja plicata, Chamæcyparis lawsoniana, Chamæcyparis pisifera, Tsuga heterophylla) at the Eberswalde Institute and discusses their most significant results from the point of view of a silviculture-expert. One element of particular importance within this analysis is the comparison of productivity of the researched species in relation to yield tables for Scots pine. Experiments concerning the productivity and usefulness of important tree species of alien origin for different scenarios of climate change (dangerous for the natural environment of Central Europe), have been conducted for over 130 years and the results of those experiments are a further subject of this paper.

Opis:
The paper describes the spatial diversity of 30−year old Douglas fir stands established by planting on fresh mixed coniferous and fresh mixed broadleaved sites. Analysis was carried out with reference to the horizontal structure (type of tree distribution over an area) and the spatial diversity of living trees size (dbh and height). Easily measurable structural indices as Clark−Evan aggregation index, contagion index and the height and diameter differentiation indices were used.
