Opis:
The data of monitoring of natural monuments in the Jasienica and Jaworze communes (Silesian Voivodeship) deriving from 1999, 2008 and 2019 were compared between the periods and communes. The conducted studies involved determining metric data (including tree height and diameter at breast height – DBH) and assessing health condition of monumental trees. A total of 65 trees were included in the research from 2019, dominated by Quercus robur (28 specimens) and Tilia cordata (9). The health condition of trees was the result of the damage that occurred. Monumental trees in the Jasienica commune were characterized by average (60%) or poor (40%) health condition. In the Jaworze commune, merely 14% of trees have poor state of health. The remaining trees were in average (38%), satisfactory (26%) and good (22%) health condition.

Opis:
The observation of the rapid rate of plant cover transformation caused by urbanization and agricultural technology was the inspiration for undertaking the study in rural areas. The study was carried out in the Sandomierz Basin in four typical villages with varying degrees of the anthropogenic impact. The changes observed included: Koszyce Małe – evident transformation of fields and meadows into building land; Kolbuszowa Dolna – intensive changes in land use, abandonment of fields and meadows, and river regulation; Roźwienica – emergence of new habitats for plant colonization after reclamation of land previously occupied by a brick factory and a landfill; Krzeczowice – intensive crop cultivation and unchanged land use. In 2009–2010, floristic investigations with the patrol method were carried out in these areas. The historical-geographical classification and indices of the anthropogenic changes of the flora were employed in the analysis. Substantially, domination of synanthropic species over non-synanthropic spontaneophytes was noted in the analysed floras. In the synanthropic species group, the proportion of apophytes was 3-fold higher than that of anthropophytes. Archaeophytes were more abundant than kenophytes. The flora of Krzeczowice, an area affected by long-term anthropopressure, was by approx. 30% less abundant than that in the other villages; it was also characterised by the highest synanthropization index, apophytization index, and index of apophytism of spontaneophytes. In turn, the flora found in Kolbuszowa Dolna was rich due to the presence of a wide variety of habitats; it was characterised by the lowest apophytization index accompanied by the highest anthropophization index.

Opis:
Low level of physical activity is one of the main problems of modern society’s health. Research results suggest that Poland is a country characterised by low physical activity, with city dwellers being more active than villagers. So far, the research issues of physical activity of city dwellers have not included a context of a metropolitan area. Therefore, the aim of this research was to determine the level of physical activity of the inhabitants of the Poznań Metropolis and to analyse selected health, demographic, and socio-economic factors influencing such activity. A questionnaire survey was conducted from March to June 2016 on a group of 1584 inhabitants of the Poznań Metropolis. The survey was based on a short version of the International Physical Activity Questionnaires – IPAQ. The results showed that 33% of the inhabitants of the Poznań Metropolis showed sufficient, 48% – high level of physical activity, and only 17% of the respondents did not meet the WHO recommendation for physical activity. Statistical analysis based on the CHAID classification tree algorithm indicated the highest influence of age, gender, income, home location, and marital status on the level of physical activity of the inhabitants of the Poznań Metropolis. The analysis did not find statistically significant correlation between the Body Mass Index BMI and the level of physical activity.

Health state of Rhus typhina was evaluated in 59 localities and 74 sites over the years 2001-2003 with scope (1) to identify the parasitic mycoflora of R. typhina in Slovakia and (2) to identify the occurrence of Cryphonectria parasitica, declared as an quarantine pest by the EPPO, besides the chestnut (Castanea sativa Mill.) and oak (Quercus sp.) also on R. typhina. The fungus Botryosphaeria ribis (Gross.) Dugg. (pycnidial state Dothiorella mali (Ell.) Ev) caused damage to the R. typhina. Damage to R. typhina caused by B. ribis was only recorded in 15 localities. Mean growth rate of hyphae of the fungus ranged from 25.7 to 48.3 mm after 96 hours of cultivation. The most appropriate medium for cultivation was 3% potato dextrose agar. The occurrence of the fungus Fusarium oxysporum Schlecht and mainly of quarantine fungus C. parasitica has not been recorded in the evaluated sites.

Celem pracy było określenie zdrowotności wybranych drzewostanów sosnowych Nadleśnictwa Szczecinek. Obserwacje zostały przeprowadzone w 2014r. na 15 stałych powierzchniach badawczych, zlokalizowanych na dwóch typach siedliskowych lasu (BMśw oraz LMśw) na gruntach leśnych oraz porolnych, reprezentujących klasy wieku od II do VI. Ocena stopnia uszkodzenia koron drzew została przeprowadzona na podstawie metody bioindykacyjnej opierającej się na trzech kryteriach: defoliacji, liczby roczników igieł oraz stopniu prześwietlenia korony. Analiza stanu zdrowotnego wykazała, iż 72,2% drzewostanów objętych badaniami było uszkodzonych w stopniu słabym, gdyż zostały zakwalifikowane do 0 i I stopnia uszkodzeń. Silnego oraz całkowitego stopnia uszkodzeń nie wykazano. Średni ubytek aparatu asymilacyjnego wyniósł 19,56%. Drzewostany wyrosłe na gruntach leśnych charakteryzowały się niższą średnią defoliacją korony drzew (18,19%), natomiast ubytek aparatu asymilacyjnego na gruntach uprzednio użytkowanych rolniczo wyniósł 20,82%.
The aim of the study was to determine the health condition of selected Scots pine stands in Szczecinek forest district. Observations were carried out in 2014 on 15 permanent research plots, located on two types of forest habitat (BMśw and LMśw) on forest land and former farmlands, representing the age class II to VI. The evaluation of the damage to the crowns has been carried out on the basis of the bioindication method, which is based on three criteria: defoliation, the number of needle age–groups and type of tree crown attenuation. The analysis of health condition showed that 72.2% of the researched stands were damaged to the lesser extent, s they were qualified to the 0 and I degree of damage. The strong and total degree of damage has not been found. The average loss of assimilation apparatus was 19.56%. The stands growing on the forest land are characterized by a lower average defoliation of tree crowns (18.19%), while the loss of assimilation apparatus on land previously used for agriculture amounted to 20.82%.

Negative alterations of hydrological conditions connected with transformations of physical and chemical soil properties are important problems affecting condition of historic parks and gardens. Consequences of those alterations are noticeable in deteriorating condition of old trees, their dying and falling and also in destruction of compositive arrangement of park and garden. In the research results of complex hydrological, soil and dendrological experiments carried out in the years 2011-2013 in the area of historic park in localities Podwilcze (commune Białogard) were considered. In the park of Podwilcze as a result of drainage ditches neglect and rise of water level in no-flow artesian-fed pond water table rise took place within the park limits. Soil erosion, surface and underground flows, local inundations were also observed. It affected many fallen old trees, development of fungous diseases and natural succession of plants of wet habitats. Urgent hydrotechnical and meliorative works should be conducted in the analyzed park to regulate water-air relations meeting the optimal requirements of precious primary afforestation.
Jednym z problemów wpływających na stan zachowania historycznych założeń parkowych i ogrodowych są negatywne zmiany warunków hydrologicznych, pociągające za sobą przekształcenia właściwości fizycznych i chemicznych gleb. Skutki tych zmian uwidaczniają się w pogarszającym się stanie zdrowotnym, zamieraniu i wykrotach cennego starodrzewu oraz w zniszczeniu układu kompozycyjnego parku i ogrodu. W pracy przedstawiono wyniki kompleksowych badań hydrologiczno-glebowych i dendrologicznych prowadzonych w latach 2011-2013 na terenach zabytkowego parku w miejscowości Podwilcze (gmina Białogard). W parku w Podwilczu na skutek zaniedbania rowów melioracyjnych i podniesienia poziomu wody w bezprzepływowym stawie zasilanym wodami artezyjskimi, nastąpiło wyraźne podniesienie poziomu wód gruntowych w obrębie założenia parkowego, jak również obserwowano erozję materiału glebowego, przepływy powierzchniowe i podziemne oraz lokalne podtopienia terenu. Spowodowało to liczne wykroty starodrzewu, rozwój chorób grzybowych i naturalną sukcesję roślin siedlisk wilgotnych. W analizowanym parku należy podjąć pilne prace hydrotechniczne i melioracyjne w celu uregulowania stosunków wodno-powietrznych, spełniających optymalne wymagania cennego pierwotnego zadrzewienia.

Opis:
In this paper, we describe the assessment of Norway spruce (Picea abies Karst.) trees health by the use of low-altitude aerial photos taken in the first half of June, so during the growth of trees and extensive changes in their crowns. Another differentiating factor is the composition of the stand, where there are trees grown from seeds collected from several remote locations. Images were taken in RGB and IR ranges and processed to orthomosaic, which was used to assess the condition of the trees. The aim of the study was to evaluate the possibility to acquire on this way reliable information about the condition of the trees, by comparison with the results of field research conducted in parallel. The differences between the assessments of trees damage in the field and on the basis of ortomosaics are not large, in all cases less than half a degree. The differences in results from field observations, and the picture are slightly greater in the case of trees observed on the discolored parts of orthomosaics. It is noticeable that the observer has difficulty in these conditions in the appropriate reading of degrees of damage. Although we used images taken in the unfavorable season (intensive development of trees) and related to the forest made up of trees of different origin, which is expressed at different rates of phenological events, the obtained results are with high compliance between field assessment and on the basis of the image. In the case of trees located outside the discoloration assessment results achieved on the basis of pictures were similar to the degree of damage reconized in field.

Opis:
The health condition of spruce stands in the Moravian-Silesian Beskids is affected by several predisposition factors, the most important of which is the allochthonous character of spruce grown on improper sites. When exposed to a low supply of nutrients and intensive mechanical damage mainly by game, the trees are susceptible to rot infestations, climatic agents and mechanical destruction by snow, hard rime and wind. At present, air pollution does not show any significant impact on the spruce stands; it rather acts as a less important predisposition factor on mountain peaks. The physiological condition of trees is not impaired to the extent which would facilitate infestation with phytophagous or cambioxylophagous insects.

China's electric power construction is renewing Increasingly, and the network is complex and changeable where the automation is getting higher. In this paper, Fuzzy evaluation system is established according to fault tree, and the estimation of transformer’s state is judged by analytic hierarchy process. Bayes-discriminant and discriminant formula are used to discriminate transformer’s attributes, which are based on historical data. The machine identification of transformer faults combines the fuzzy evaluation and Bayes-discriminant. It’s accuracy can be improved by correcting parameters. This method can effectively avoid subjective interference caused by artificial weights. The example shows that this method could be applied to judge health status of electric power equipment and this method can play an early-warning role in the operation of monitoring system.

Opis:
The quality assessment of spruce seeds consists mainly in determining their germination capacity, including germination rate (speed), but also purity and weight. Internationally recognised methods are listed in the ISTA Rules for Seed Testing which also specify test conditions. Some countries such as Poland use modified methods. Apart from providing information about the purity of a species, purity testing can also identify the proportion of winged seeds in each seed lot. Germination tests yield data on the maximum germination potential of a seed lot which are used to compare the quality of different lots and to establish the field sowing values. This paper presents the methods used for assessing the quality of Norway spruce seeds, and discusses their advantages and disadvantages and the problems that need further investigation.

Opis:
In connection with the decline of spruce stands on the Krynica plots of IPTNS-IUFRO 1964/68, observed in the last decade and attributed to the so-called spiral disease, an attempt was made to determine whether the current health condition of trees is influenced by genotype (provenance). As shown by preliminary observations, the spruces differed in the degree of survival depending on provenance. The inventories of died or broken trees to be removed during the sanitary cutting, made in the years 2000, 2003, 2004 and 2008, yielded also information about the number of spruces that remained in the blocks of the experiment for each provenance and provenance region by Krutzsch (1968). Analysis of variance showed that genotype (provenance) has a statistically significant effect on the survival of trees. In the years 1999-2008, spruces from region 21 (Bohemian Forest) displayed the poorest survival rate in the conditions of the Beskid Sądecki Mts., while those from region 80 (Eastern Siberia) survived best.

Opis:
Due to the deterioration in the health condition of Norway spruce on the IPTNS-IUFRO 1964/68 observation plots in Krynica (Poland), there was an urgent need to determine the cause of the decline in order to design preventive measures. For this purpose, a health inventory was carried out in the years 2002 and 2003. This included an assessment of the condition of crowns in 144 trees and a thorough examination of 29 felled trees. It was found that individual trees or groups of trees have declined in some blocks of the experiment. The tops of some trees were dying and the crowns were getting transparent. The discolouration (turning brown) of needles was quite common and even green needles were shed. Some of the roots showed symptoms of necrosis and died. Seven taxa of pathogens were isolated from the diseased roots and trunk parts of spruces, among them Phytophthora citrophthora, Fusarium avenaceum, F. solani and Trichoderma. The number of diseased trees was related to provenance. The provenances Babenhausen (Germany), Frantiskovy Lazne (Czech Republic), Traunstein 1/4 D, 6 A, B, 7 A (Germany), Wundsiedel-Weissenstadt (Germany), Mestwinowo (Poland), and Magland (France) proved to be more susceptible than others to fungal pathogen attack.
