    Opis:
    In the experiment eight populations of Picea abies were chosen at 100 m intervals between 500 m and 1200 m altitude a.s.l.. In each population wood core samples were collected from 14–19 trees (126 cores total), and measured using a Corim Maxi device. At four of the eight sites (every 200 m in elevation between 500 m and 1100 m a.s.l.), the diversity of ground vegetation was evaluated, and temperature was recorded at every 100 m of altitude. The highest average radial increment of spruce occurred between the altitudes 800–1000 m a.s.l., which is probably the optimum for spruce. The larger increment indices observed at higher altitudes may signify a high growth potential of spruce. It may also suggest a recent upward shift of the optimum growth zone for this tree species. In 15 phytosociological records, the presence of 148 plant species forming plant associations: Dentario glandulosae- Fagetum typicum (sub-mountainous and mountainous form) and Abieti-Piceetum, and community Abies alba-Rubus hirtus, was documented. No relationship was found between ground vegetation species diversity (expressed by Shannon-Wiener index) and levels of stand diversity. The vegetation species diversity varied with the elevation above sea level: the highest plant diversity was found at 500 m a.s.l., and decreased with increasing altitude. The potential increase in air temperatures may result in changes to the altitudinal range of many plant species including trees, and consequently in an upward shift of the boundaries of plant zones; in this case the sub-mountainous and lower mountainous forest zone. In this region, the optimal zone for Norway spruce may be restricted to the highest elevations.

    Opis:
    In April 2005, 2 sets by 3 stacks containing Norway spruce logs were exposed in sunny and shaded place within the forest. In each set logs in 2 stacks were sprayed with Ca(OH)2 aquatic dilution with the addition of milk and vegetable oil (1 stack as a whole, and 1 individually – log by log), and 1 left for control. At the end of June 9 insect species infesting the logs were found, among which the most frequent were Hylurgops palliatus (Gyll.) – 41,1% and Pityogenes chalcographus (L.) – 35,6%. The treated logs were less (sometimes – significantly) infested by the most frequently occurring species, but the difference between two variants of treatment was not very high. The logs exposed in sunny place were less infested than those stocked under stand canopy. As this environmentally friendly treatment reduced the infestation of logs by bark beetles (including I. typographus), it can be recommended especially for mountain areas under protection regime.

    Opis:
    The classic trap logs are attractive for Pityogenes chalcographus. The infestation density and the length of infested part of stem can be increased by the use of synthetic pheromones of this species. The use of trap logs is generally recommended, but their effectiveness can be enhanced by the use of synthetic pheromones.

    Opis:
    A monitoring network was set up in 2002 in order to define the distribution range of Ips duplicatus in mountain Norway spruce stands in southern Poland. Borregard pipe traps baited with synthetic pheromone Duplodor (Chemipan, Poland) were installed on 70 locations situated above 600 m a.s.l. in Carpathians and Sudeten. The occurrence of I. duplicatus was confirmed in 17 locations in the western part of Carpathians, including those located around 1000 m a.s.l., while no beetles were caught in the eastern Carpathians nor in the Sudeten. The distribution range in Polish mountains is adjacent to those in northern Slovakia and northern Moravia (Czech republic).

    Opis:
    At the end of 2013, Norway spruce stands in the area of the Tatra National Park were severely damaged by strong storms especially in the Kościeliska Valley region. In the following spring of 2014, a survey recording the occurrence of the spruce bark beetle Ips typographus (Coleoptera, Curculionidae, Scolytinae) was initiated in order to describe the dynamics of beetle reproduction in relation to protection measures executed in wind-damaged stands. Ten research plots with 20 trees each were established in a so-called active protection zone, where the broken and fallen trees had been processed and removed in 2014, and in a passive protection zone, where no actions were taken, and the dynamics of Norway spruce mortality due to bark beetle infestation including quantitative parameters (infestation density, sex ratio of beetle populations) were examined. The entomological analyses were performed on 25×25 cm large bark samples taken from four (active zone) or two (passive zone) tree sections. In the first year of the survey, no infested standing trees were recorded on the plots and the colonisation of fallen and broken trees was very weak. In the second year (2015), infestations appeared in larger numbers on the plots with passive compared to active protection but the infestation density was 0.89 mating chambers per 1 dm2 regardless of the protection status. In the third year (2016), most of the remaining living spruces had been infested with a mean density of 0.82 m.ch. per 1 dm2. In 2015, the proportion of females in the beetle population was 65.8% being higher in the active (68.4%) than the passive (64.0%) protection zone, while in 2016 the proportion was 63.5% and in this case slightly higher in the passive protection zone (63.9% as compared to 63.2%). These results are in accordance with patterns observed in wind-damaged Norway spruce stands of other areas in Poland and Europe and demonstrate the usefulness of forest management procedures in mitigating I. typographus outbreaks.

    Opis:
    In the end of 2013 the Norway spruce stands in the Kościelska Valley in the Tatra National Park (S Poland) were severely damaged by the wind. In the next year about 22,000 m3 of timber from broken and fallen trees was processed and removed from the active protection zone, whilst in the strict protection zone those trees were left. In 2014, when the presented survey started, the infestation of lying and surrounding standing trees was very low, but starting from 2015 an intensive bark beetle Ips typographus outbreak affected the survived stands. No−intervention strategy was implemented by the national park in both zones, regardless their formal status at that time as well. In 2015 a set of 10 observation plots (200 trees in total) was established in both active and passive (strict) protection zones (5 plots in each zone). In 2017 a new set of 12 plots (240 trees in total) was installed (6 plots in each zone). On each plot the breast height diameter of all trees was measured and the relative mortality of trees (share of attacked spruces) was recorded each year. The infestation density and sex ratio were defined on the 25×25 cm bark samples taken from 138 trees in 2 trunk sections located 1.5−2.0 above the ground and in the midway between tree and crown bases. The bark beetle attack on living spruces in 2015 differed between the active and strict protection zones. The relative tree mortality was lower in active than in passive protection zone (20 and 39% respectively), but later it gradually came to be similar in both parts of the area (73.3 and 77.5%, respectively in 2017). In the initial outbreak phase, thinner (weaker) trees were attacked, and in the following years – stronger ones, although in the active protection zone the opposite pattern occurred initially. The attack density decreased in subsequent years, being higher in active protection zone, with gradually decreasing difference between zones. Thicker trees were attacked with lower intensity. The share of females, higher in active protection zone (68.2 vs. 63.9%), gradually decreased to (57.9 vs. 51.2%). The initial decrease of bark beetle attack intensity in the active protection zone gradually disappeared after the no−intervention strategy was applied. The resulting extended bark beetle infestation and its increasing intensity in both parts of the area, demonstrate the appropriateness and effectiveness of active protection measures applied in 2014.

    Opis:
    Spruce bark beetle Ips typographus (L.) (Col.: Curculionidae, Scolytinae) outbreaks occur in managed and protected forests alike, but although known of for a long time, management and control of this insect is a controversial subject due to the forests’ diverse nature and protection status. In this paper, an overview of the bark beetle, conditions leading to outbreaks, natural enemies and the efficiency of control measures is presented and put into perspective with regards to the current controversies concerning outbreak management. The Białowieża Primeval Forest is central to this discussion, because the area remains divided into parts with different nature protection statuses. Ideas concerning the current but also future outbreak progress and possible issues with the management of natural resources in this area are presented.
