“…3). A similar peak of seasonal fire occurrence has been observed in southern Sweden (Drobyshev et al 2012), Finland (Lehtonen et al 2016), and Poland (Ubysz et al 2006). The observed changes in timing and duration of fire seasons have been attributed to climate change (Westerling et al 2006;Szczygieł et al 2008;Turco et al 2016).…”

Highlights• Climate effects and human influence on forest fire activity in Latvia was assessed using time-series analysis.• Drought conditions during summer season had the strongest effect on fire activity of tested climatic variables.• Negative trends and spatial distribution pattern of fire activity suggests of prevailing human influence on forest fire regime over the 20th century. AbstractFire as disturbance of forests has an important ecological and economical role in boreal and hemiboreal forests. The occurrence of forest fires is both climatically and anthropogenically determined and shifts in fire regimes are expected due to climate change. Although fire histories have been well documented in boreal regions, there is still insufficient information about fire occurrence in the Baltic States. In this study, spatio-temporal patterns and climatic drivers of forest fires were assessed by means of spatial and time-series analysis. The efficiency of Canadian Fire Weather (FWI) indices as indicators for fire activity was tested. The study was based on data from the literature, archives, and the Latvian State Forest service database. During the period 1922-2014, the occurrence and area affected by forest fires has decreased although the total area of forest land has nearly doubled, suggesting improvement of the fire suppression system as well as changes in socioeconomic situation. The geographical distribution of forest fires revealed two pronounced clusters near the largest cities of Riga and Daugavpils, suggesting dominance of human causes of ignitions. The occurrence of fires was mainly influenced by drought. FWI appeared to be efficient in predicting the fire occurrence: 23-34% of fires occurred on days with a high or extremely high fire danger class, which overall had a relative occurrence of only 4.3-4.6%. During the 20th century, the peak of fire activity shifted from May to April, probably due to global warming and socioeconomic reasons. The results of this study are relevant for forest hazard mitigation and development of fire activity prediction system in Latvia.

“…Insect control was carried out at biweekly intervals. The beetle specimens collected from the traps were identified to the species level with the keys from Trautner and Geigenmüller (1987), Hůrka (1996) and Klausnitzer (2005). The beetle assemblages were analysed using individual dominance indices to reflect the percentage of particular beetle species in the pool of all the insects collected at a given study site.…”

“…It is also characterized by permanent factors influencing the water balance, such as precipitation and cyclical long-term droughts, leading to reductions in groundwater (Kubicz et al 2019). The fully biocenotic conditions of the forests and their uniform age and species structure make them particularly vulnerable to fires (Ubysz et al 2006;Szczygieł 2012). According to the European Forest Fire Information System, Poland ranks third (after Portugal and Spain) in the average annual number of fires and eighth in the area covered by fires (Szczygieł 2012).…”

Effect of scots pine forest management on soil properties and carabid beetle occurrence under post-fire environmental conditions - a case study from Central Europe

et al. 2020

Background: Fires have a fundamental impact on phytocoenoses and, depending on the size of the fire, can have a positive or negative effect. The role of fires in the formation of the species composition of plants, restoration of stands and changes in soil properties is well studied. However, the long-term relationship between forest management methods, soil properties and epigeic entomofauna assemblages in post-fire areas is still not clear. The effects of Scots pine stand management methods on biochemical soil properties and ground beetle assemblages in the largest post-fire area in Central Europe after the second World were investigated. The study was conducted in the Rudy Raciborskie Forest district in southern Poland. The soil properties and epigeic beetle community structure were analysed. The research covered areas with natural and artificial pine regeneration, which were subjected to various care treatments. Results: The tendency for higher accumulations of organic matter in the soil of stands that underwent natural regeneration was proven. The stimulating role of soil organic carbon on the activity of dehydrogenases in the soil of naturally renewed areas with silvicultural treatment (NRAT) was noted. Regardless of the manner of stand regeneration, the activity of β-glucosidase was higher in the areas in which breeding treatments were practised. Furthermore, managed forest stands presented a higher abundance of carabid beetles than stands without treatment practices. Thirteen epigeic beetle species from the families Geotrupidae, Carabidae, Curculionidae, Cerambycidae and Silphidae were captured, with beetles from the first two families being the most numerous. Rare epigeal carabid species in the fauna of Poland and Europe, such as Carabus glabratus (Paykull) and Carabus auronitens Fabr., found appropriate habitat conditions for survival in the post-fire areas. Compared with the other areas, in the NRAT area, there were better stand and soil properties and more features conducive to epigeic entomofaunal occurrences. The highest post-fire content of polycyclic aromatic hydrocarbons was recorded in the soils of the sites that underwent artificial regeneration. The results suggest that preparing the soil before the introduction of new vegetation affects the amount of aromatic hydrocarbons (PAHs).

This paper describes the method of forest fire danger assessment in Poland depending on dynamic weather changes. The degree of forest fire danger influences the type of organizational actions, which the forest administration and rescue units are obliged to take on a given day. Apart from that, an analysis of basic meteorological factors influencing the degree of forest fire danger in 2007 and occurrence of forest fires in the fire season was presented.
