Opis:
Black alder is a species capable of producing sylleptic shoots. This process is also detected in alders at older age. The objective of this work is to characterise sylleptic shoots and to determine the role they play in the formation of crown branching. The empirical material used in the experiment was collected in the north and south of Poland and considers both young and old trees.

Opis:
A comparative analysis was made for different measures of location and variation in height increment of the main stem of the mature black alder from the north−eastern region (N) and two southern regions (S1 and S2) of Poland. Correlation was found between annual height increment and tree age and height, as well as the number of the nodes along the shoot and the length of the internode. It was demonstrated that the trees producing long shoots in a given year would produce long shoots also in the successive years.

Opis:
The paper provides research results concerning the relationship between age, absolute height and relative crown length of black alder. Analysis of the ratio of relative crown length to tree height of black alder trees allowed to develop a crown length model. Alder is capable of producing a secondary crown, which entails the shortening of the non−branched section of the trunk. A relationship has been found between the length of the primary crown and the length of the secondary crown depending on elongation of the secondary crown at the cost of shortening of the primary crown.

Opis:
The study presents the assessment of damage to beech stands using four methods, including that taking into account the radial increment. The condition of stands in 2016, and the growth response of trees to the environmental changes since 1956 are described. The measurements and observations were carried out on 18 sample plots (tab. 1) located in south−western Poland. The mean defoliation accounts for 32.5% ranging from 16.9 to 56.9%, while the average defoliation class value is 1.62 ranging from 0.75 to 2.38. The proportion of trees was found to be the highest (approx. 60%) in class of moderate damage (fig. 1a). The mean value of vitality is 1.17 (ranging from 0.75 to 2.38). The proportion of trees in vitality classes differs significantly from that in defoliation classes. The highest number of trees (approx. 80%) was found to be within damage class of weakened trees (fig. 1b). The assessment of damage to trees based on synthetic damage index (defoliation and vitality combined using formula [1]) is similar to the assessment method based on tree vitality. The mean value is 1.07, ranging from 0.63 to 1.70. The largest proportion of trees (over 80%) was found to be within class 1 (fig. 1c). The index SynZ combines defoliation and vitality, as well as the growth response of trees over the last 15 years according to formula [2]. Its values range from 0.82 to 1.79 with 1.21 on average. The largest proportion of trees (over 70%) was found to be within damage class 1 (fig. 1d). The response of trees to environmental changes is an important indicator of the growth conditions. The proportion of trees with negative growth responses increases from period to period, while the proportion of trees with neutral and positive responses decreases (fig. 2). The analysed beech stands show fairly large differences in the level of the damage. The most likely cause of this situation are droughts occurring in recent growing seasons, especially in 2012. Of the methods deployed to assess damage to beech trees, the morphological−growth one is the most accurate, but the most laborious. Therefore, it is preferable to use a synthetic damage index as both tree defoliation and vitality can also be assessed outside the growing season.

Opis:
The study presents the analysis of the increment of tree diameter at the breast height in connection with two variants of the method of assessment the damage to Norway spruce stands. Variants utilise different assessment criteria. The first one is based on the tree's defoliation, the other one – on the damage index W that links defoliation, condition of the tree−top and branching in the middle part of the crown. Detected relations between damage criteria and type of the increment reaction show that index W characterises the damage to trees and stands better than feature A (defoliation). Therefore, method of assessment the damage to trees and stands based on this parameter is suggested for utilisation in the forestry practice.

The paper presents the criteria for assessment of the damage to Norway spruce determined on the basis of its crown development. Three features were included: condition of the assimilation apparatus (feature A), condition of the tree−top (feature B) and tree vitality (feature C). Feature A is based on the defoliation. Feature B assesses the length of the last height increments and their branching models. Feature C includes the loss of branches in the middle part of the crown, the presence of branches of 2nd and higher orders as well as condition of proventive sprouts (developed from dormant buds). Determined criteria may be applied in the methods of assessment of the damage to stands and larger forest objects e.g. management region, forest region, nature−forest regions.

tree mortality
critical value of deadwood harvest
wind damage risk model
forest threat measure
Opis:
A dynamic process of mortality of Norway spruce stands in south−west Poland, mainly in the Sudety Mts. was observed in 2015. It was associated with an insufficient amount of precipitation in the growing season. This process was intensified by the outbreak of insects, especially bark beetles. The aim of the paper was to verify the hypothesis that the application of the stand damage risk model allows to identify stands, which may possibly be predisposed to mortality, after a long−lasting drought in the growing season. The studies concerned the forests of the Wrocław Regional Directorate of State Forests (tab. 1). Their area covers 245,000 ha, the timber volume amounts to 83 million m3 (338 m3/ha) and the volume increment to 2.3 million m3 (9.4 m3/year/ha). The fraction of spruce is the largest (50.3%), ranging from 7.1% (Pieńsk Forest District) to 84.8% (Lądek−Zdrój Forest District). The average age of stands is 74 years, ranging from 56 (Pieńsk Forest District) to 85 years (Jawor Forest District). The drought in 2015 caused an increase in the dynamics of spruce decline. The ratio of harvested to model deadwood volume at a level of up to 5% was assumed the ‘norm’ that characterizes the process of natural spruce mortality. Values higher than normal mean a more intense process of tree mortality caused by external factors (e.g. hurricane winds, floods, droughts). In 2014, the harvested deadwood was below the norm in 15 forest districts (fig. 1). In 2015, the highest ratio values (above 20%) were reported in the Wałbrzych and Szklarska Poręba forest districts (fig. 1). In 2016, the harvest of deadwood in each forest district exceeded the norm, and the highest values were found in the Jawor (102.3%), Bardo Śląskie (83.3%) and Świdnica (69.7%) forest districts. In 2017, the highest ratios of harvested to model deadwood volume were reported in the Bardo Śląskie (117.2%), Jawor (83.6%), Henryków (83.5%) and Świdnica (67.1%) forest districts. The model was found to identify also the stands that are most threatened by droughts. These are stands in the highest damage risk factor Wr class. The highest percentage of deadwood in this damage class was in Jawor (88.8%), Bardo Śląskie (81.9%), Miękinia (79.4%), Świdnica (76.7%), Henryków (73.8) and Złotoryja (73.6%) forest districts. It was also shown that the average value of the measure of threat to forests Ms was 35, qualifying them as highly threatened (fig. 3). Forests characterized by the highest level of threat Ms>40 was found in five forest districts, while in nine others the level of threat was high. The forests of the Sudety Mts. are threatened by the decline and the main direct causes of this process was the long−lasting drought in the growing season, causing damage to the stands earlier weakened by wind and other factors.

Opis:
The dynamics of decline of Norway spruce forests in the Beskid Śląski Mts. (S Poland) in a 2007−2016 period was analysed based on data from the State Forests Information System. For that purpose we used modified growth model and wind damage risk model. The harvested timber volume (salvage cuts) exceeded the allowable harvest modeled with the stand growth model by 270% in years 2007−2010 (earlier period) and by 89% in the 2011−2016 (later period) period. The highest volume exceed (503 and 307% for earlier and later period respectively) was recorded for the Wisła Forest District. For the deadwood, the harvested volume exceeded the modeled one by 45% (162 in earlier, and 59% in later period). In the Węgierska Górka Forest District the harvested volume amounted to 287% of the modeled one (438 in earlier, and 70% in later period). The largest amount of wind−broken and wind−fallen trees was found in Wisła. Their volume amounted to 48% of the modeled volume (59 in earlier, and 40% in later period). The highest exceed occurred in Węgierska Górka (89 and 70% in the later period respectively). The species composition in the analysed region changed significantly as the share of spruce decreased and share of beech and fir increased (tab. 1). Changes in the aeral fraction of stands in age classes in the Bielsko and Ustroń forest districts were insignificant (tab. 2). For Węgierska Górka, share of stands in age class <20 years increased from 11 to 40%, while the older stands fraction decreased. Major changes occurred in Węgierska Górka and Wisła as far as structure of the stands in the risk damage factor classes is concerned. Fraction for the risk factor classes I and II increased, while for class VI decreased (tab. 3, fig. 4). The highest dynamics of the wind threat measure was recorded especially in Węgierska Górka, where its value decreased from 42 in 2009 to 19 in 2016 (fig. 5). The biggest changes are likely to occur in Wisła in the next years due to the very high fraction of spruce. A significant damage caused by wind may also be expected in Ustroń, where the threat measure is high.

Opis:
The study assesses the damage to silver fir from the canopy layer in the stands of the Świętokrzyskie Mountains (central Poland) using three methods. The suitability of these methods was also analysed by calculating the correlation between increment of the diameter at breast height (DBH) and the level of damage. In total we investigated 240 trees. The first analysed method involves tree defoliation. The mean defoliation of sample accounts for 47.8%, while majority of the trees were found to be within 2nd damage class (fig. 1). Absolute and relative DBH increment does not correlate with tree defoliation strongly (tab.). The next method is based on the assessment of the average tree damage index W that takes into account defoliation, top condition and vitality. In general, analysed trees were found to have reduced height growth and both branching in the top (fig. 2) and central (fig. 3) section of the crown. Inclusion of the secondary crown in the assessment of tree damage resulted in an increase in the vitality of the whole crown (fig. 3). The assessment of damage based on index W showed that largest proportion of trees was within moderate damage and the value of the damage index was lower than in method based exclusively on defoliation. The last method (morphological−incremental) combines the method based on damage index W with DBH increment (index Wz, formula 3). In the period 1971−1985, most of the fir trees reacted negatively to the environment changes (growth reduction), while the proportion of trees with positive responses decreased. In the period 1976−2000, the proportion of trees with negative response decreased, while the proportion of firs with positive and neutral responses increased (fig. 5). The period 2001−2015 faced the dominance of trees showing neutral growth responses, the proportion of trees with positive responses was fairly high, while the proportion of trees with negative responses was the smallest. The highest value of the correlation coefficient (r=–0.661) was found for the correlation between the relative 10−years DBH growth and damage index Wz2(tab.). Of the three discussed damage assessment methods, this method is therefore considered the most accurate.
