The aim of this study is the analysis of multiannual changeability of air relative humidity in Forest Experimental Station in Krynica Zdrój. The data comes from measurements from 19712006, which were collected at the Phytoclimatic Research Station of the Department of Forest Climatology in Mochnaczka Wyzna (718 m a.s.l.) and meteorological station in Krynica Zdrój health resort (580 m a.s.l.) also Jaworzyna Krynicka summit (1113 m a.s.l.). The long-term mean annual air relative humidity was 84.9% with deviation of 2.4%. The highest long-term mean monthly sum of the air relative humidity falls to December (92.5%), and the lowest falls to May: 76.8%. The air relative humidity trend index has totaled -6.1% in multiannual 1971-2006. Five-year forecast has exerted negative trend of air relative humidity on Forest Experimental Station in Krynica Zdrój.

The analysis of the meteorological vegetation season from the period of 1971-2000 was recorded in the Beskid Sądecki Mountains, in the phytoclimatic research station at Kopciowa near Krynica. The station is located at the altitude of 720 m. Its geographical coordinates are φ = 49º27 N and λ = 20°58' E. This paper jointly presents the length of the vegetation season and dates of its beginning and end. In the years 1971-2000 the meteorological vegetation season began on average on 14 April and finished on 19 October. Its duration was 189 days. The shortest vegetation season was noted in 1997 and lasted 160 days. The longest one occurred in 1989 for 211 days. The duration and dates of the beginning and ending are characterised by a large annual changeability. Almost 25% of annual indicators differed from one another by two weeks. The earliest date of the beginning of the vegetation season fell on March 28, 1989; the latest was on May 1, 1980. The latest end date of a meteorological vegetation season was November 16, 2000. The earliest end date was September 30, 1997. The average multi-annual air temperature of the vegetation season was 10,5°C. The warmest vegetation season in of the period of 1997-2000 occurred in 1983, with an average air temperature of 11.7°C.

The analysis of rainfall from the period of 1971-2000 recorded in the Beskid Sądecki Mountains, in the phytoclimatic research station in Kopciowa near Krynica (φ = 49º 27'N and λ = 20º 58'E, located at the altitude of 720 m) indicated a strong rising tendency of rainfall in winter, spring and autumn. It was reflected in a clearly positive trend of the annual rainfall totals, despite the falling tendency of rainfall in the summer. On average, the annual rainfall totals were 1000 mm. During this 30-year period, the monthly totals of the summer months were characterised by the strongest variability, while the winter months' variability was the weakest. The highest rainfall totals were usually recorded in June and the lowest in February. The mean annual rainfall total increased during the thirty years by 208 mm. An increase in the amount of rainfall during spring and winter and a decrease in the summer indicates that the pluvial climate of the area under research has acquired oceanic features.

The study describes an experiment with the Swiss irregular sheltherwood system. A 40-year period of research and development allows to regard it as a new method which clearly bridges the gap between the Swiss irregular sheltherwood system and the selection cutting system. A new classification was proposed: — an irregular sheltherwood and selection cutting system.

The paper presents the results of studies carried out in the Forest Experimental Station in Krynica (Beskid Sądecki Mts,, Southern Poland), where the influence of bark-stripping on height and volume increment of silver fir was analyzed on the sample plots established in stands with fir share. On the basis on measurements done in the field and on discs cut from wounded and uninjured trees, stem analyses of firs were performed. Average decrease of height and volume increment of all studied damaged trees amounted respectively 12% and 6% of the last increment before bark stripping. The comparison of height and volume increment of wounded and unwounded fir trees pointed at existence of statistically significant differences. The decrease of height and volume increment in the first year after injury, which was determined respectively on 62% and 58% wounded trees, was not affected by the dimensions of wounds and their locations on tree trunks. Only the average value of volume increment in the first three and five years after injury depended significantly on the length of wound and its location on tree trunk.

The paper presents the results on studies, which dealt with a determination of relationship between annual ring widths of wounded firs formed before and after bark stripping occurrence on the undamaged side of stem and their dependence on features and location of wounds on trunks. The injured fir trees came from ten sample plots established in the Forest Experimental Station in Krynica (Beskid Sądecki Mountains). Analyses were done on discs cut from damage fir stems at the middle of the wounds. It was found that only width of ring formed in the first year after bark stripping was smaller than before wound occurrence. Average annual ring widths from three and five year periods following damage were larger than before it in the same period lengths. The increase of annual ring width occurred in the case of larger relative width and surface of wounds.

The objectives of this study was to describe the size and position of wounds on European Silver Fir (Abies alba Mill.) and to analyse their impact on selected morphological features of crown. The studies were carried out in 10 sample plots in stands of Fir, located in the Forest Experimental Station in Krynica (Beskid Sądecki Mts.). Precise wound measurements were made and such features as growth tendency, vitality, absolute and relative crown length were determined. Wound size was characterized by mean relative width (60%), length (36% of wounds were shorter than 30 cm), and the surface area of the unhealed part of the wound (mean area ranged between 20 and 80 cm2). The most vulnerable section of the trunk to bark damage was found to be between 30 and 210 cm above ground level. The potential height of damage can be significantly limited by low growing branches. When damage intensity of the Fir Tree was >40% of trunk circumference and >30% of trunk surface, the tree was unable to reach the highest value of vitality index.

Badano tempo epifitozу opieńki w 45- i 60-letnim drzewostanie świerkowym w Leśnym Zakładzie Doświadczalnym w Krynicy. Stwierdzono, że sprawcą tej epifitozy był grzyb Armillaria obscura (Sekret.) Hermk przy współudziale Heterobasidion annosum (Fr.) Вref.

The studies were conducted in 45-60-year-old Norway spruce stand situated at the elevation of 700-720 m above sea level in the Experimental Forest in Krynica The appraisal of health condition of spruce trees under investigations was carried out three times, 10 and 15 months apart, according to 5-class tree health scale. Trees in the initial stage of the disease constituted 39% at the beginning of the study, and only 2% a year. Trees in the initial stage of the disease constituted 39% at the beginning of the study, and only 2% a year later (tab. I). The percentage of dying trees had increased almost up to 73% (tab. I). During 1-year study the health condition of as much as 35% оf spruce trees worsened by 2 tree health classes (tab. 2). The highest number , i.e. 27 trees, were transferred from class 11 to class IV (lab, 2). The highest number of dead and dying trees was present in group of trees of height up to 20 m (fig. 1). All dead and over 59% of dying trees were in the group of trees of d.b.h, up to 23 cm, and a year later there were no trees with initial stage of the disease in this group (fig. 2). The results of a dendrochronological study revealed that breakdown of increment, i.e. its permanent drop below ал average value in the class of diseased trees (II-IV) occurred about the year 1975 (tah. 3, fig. 3). It may be assumed that when the annual increment is less than 0,7 mm trees would not regenerate the losses and die during the next 2-3 years. The crossings of 1 -spore cultures of Armillaria forming the fructifications on diseased spruces with standard European 1-spore cultures showed that Armillaria obscura was the cause of spruce mortality. This fungus was also isolated from wood cores taken from vicinity of root collar and roots, and from wood discs taken from the butts of dead and dying spruces (lab. 4). Heterobasidion annosum was isolated only from butt wood of 2 trees of health class II and from 1 dead tree (tab. 4). The studies showed that rate of Armillaria epiphytose in the stand under investigations is very high, and mass tree mortality should be expected during the next 2 years.
