“…Also, consideration of environmental factors is of great importance in understanding the state, stability, and ecological role of forest stands [56][57][58][59][60][61][62][63]. It is especially important for protection and restoration of forest ecosystems [64][65][66] as well as in their management [67][68][69].…”

Vast forest areas are spreaded in Russia and perform environment-forming, nature-protective and climate-regulating functions, including carbon sequestration. At the same time, increasing of destructive forest fires scale in recent decades has led to depletion of forest resources. To combat forest fires, it is necessary to develop preventive measures to reduce the number and severity of forest fires and establish reliable evaluation criteria for fire hazard assessment in forestry. However, indices of fire hazard assessment that exist in Russia are not always allowed to determine the degree of fire hazard reliably. The studies were performed in pine forests on the territory of the Central Forest-Steppe. The key forestry factors influencing the fire hazard situation in pine stands are identified: the presence and amount of combustible materials, the state of the stand, as well as the age structure of tree stand. According to burning indices, the highest fire hazard was common for young and middle-aged pine stands, while for ripening, mature and old-growth forests, fire hazard increasing was not observed. A set of parameters that characterize soil moisture and ground cover peculiarities have also a significant impact. Forest growth conditions were shown to be an important indicator for assessment of fire hazard class. Identified factors that have a key impact on the fire hazard in forests will make it possible to improve methodological approach for monitoring and preservation of forests.

“…While also a light-demanding pioneer, PS is an isohydric species with strict control of stomatal conductance (Oberhuber et al, 2015). Though PS is considered a drought-resistant species, severe drought led to large-scale diebacks of stands growing at marginal conditions (Vacchiano et al, 2012;Hunziker et al, 2022;Lemaire et al, 2022). The Swiss stone pine (Pinus cembra L., in the following PC) is a slow-growing, late-successional pine species that is restricted to the upper subalpine forests near the forest line as it is outcompeted by PA at elevations below 1,700 m a.s.l.…”

IntroductionClimate change affects the vitality of mountain forests through increasing temperatures and decreasing water availability due to changing precipitation patterns, earlier snowmelt, and increasing evaporative demand. Depending on species characteristics, tree growth might therefore increase in cold habitats near the forest line but decrease in water-limited conditions at low elevation.MethodsWe analyzed the tree-ring widths of five conifers (Picea abies, Larix decidua, Pinus sylvestris, Pinus nigra, and Pinus cembra) along an elevational gradient from 1,000 m to 2,320 m above sea level (a.s.l.) in Vinschgau/Val Venosta Valley in Northern Italy, one of the driest regions of the Alps (mean annual precipitation of 682 mm at 1,310 m a.s.l.).ResultsOur aim was to estimate the species-specific growth response to changing climate conditions along an elevational gradient. At low elevations, we observed a significant response to water availability not only during the actual growing season but also throughout the previous autumn for all species present. At mid-elevation, the correlation coefficients to precipitation and drought indices (SPEI) were highest for Picea abies. At high elevations, the positive correlation of growth with temperature was smaller than expected for Pinus cembra. In contrast, Larix decidua responded positively to temperature and grew faster in recent decades.DiscussionConsidering that a further increase in temperatures will reduce plant water availability during the growing season, our space-for-time approach provides an outlook on future growth conditions of conifers in larger regions of the European Alps. Water limitation will affect tree growth and vitality not only at low elevation in the valleys but also at mid elevation on mountain slopes, potentially impacting timber production and protective and recreative functions of forests. Near the forest line, the different capabilities of tree species to benefit from higher temperatures might lead to changes in species composition.

“…Although precipitation deficits appear to be the main driver of Scots pine decline (Hunziker et al, 2022), when combined with biotic agents, they can accelerate this process (Lemaire et al, 2022). Even though resilience enhanced by tree growth release may compensate for the dieback effect, projected warming may weaken this process (Margalef-Marrase et al, 2023).…”
