It is used for its superior timber production and resistance to environmental conditions. This literature review paper consists of 150 references and presents a summary of research results dealing with the lodgepole pine potential in general with a specific focus on Europe from 1910 to 2022. It summarizes the importance, taxonomy, biological and ecological characteristics, site requirements, production and silviculture, risks and pests, as well as the potential of this tree species for forestry and the wood industry in relation to global climate change. Pinus contorta also has a considerable potential in Central Europe, especially at extreme sites with strong anthropogenic impact and in polluted regions. This tree species is very resistant to climatic factors and extreme events compared to other coniferous tree species. Moreover, its annual increment reached from 3 m3.ha-1.yr-1 on reclamation sites to 18 m3.ha-1.yr-1 in favourable environmental conditions. On the other hand, caution must be taken for possible invasive behaviour outside its natural range. Its importance can increase with ongoing climate change and the decline of native tree species.

In order to manage sustainable forests, tree species history, distribution, and their future prospects are vital. Using standardized quantitative approaches, the age, radial growth, and size class distribution of Abies pindrow (Himalayan fir) were determined from three different altitudinal sites (i.e. high, middle, and lower). The results indicate that Himalayan fir growing in the high-altitude site (Ayubia, 2 917 m a.s.l.) of moist temperate forests of the Himalayan mountains showed lower radial growth (0.13 cm) than in the middle (Bara Gali, 2 617 m a.s.l.; radial growth = 0.13 cm) and lower (Kuldana, 2 455 m a.s.l.; radial growth = 0.22 cm) altitude sites. Correlation analysis demonstrated that age showed a significant positive correlation (P < 0.001) with diameter at breast height. The tree-ring width chronology (totally 80 core samples) of Himalayan fir was developed from moist temperate forests of Himalayan mountains of Pakistan. At Ayubia site it possesses a long time-span (1703-2020 C.E.), followed by Bara Gali (1862-2020 C.E.) and Kuldana (1864-2020 C.E.). Further, the tree-ring width (TRW) chronology of Ayubia showed a significant positive correlation (P < 0.05) with May and June temperature, and a significant negative correlation (P < 0.05) with June and October precipitation, indicating that summer temperatures are the key factor for the radial growth of Himalayan fir. For the Kuldana site, the response of TRW chronology to temperature and precipitation was the same, however, it was significant only for June temperature at Bara Gali. The size class distribution of the high-altitude region (Ayubia) showed a higher number of individuals than the lower altitude region, indicating the lowest disturbance conditions. The absence of individuals in the early size classes and the gap in middle and mature size classes indicate a lower regeneration potential and anthropogenic impact. The pointer year analysis indicated that the Bara Gali forest is more sensitive to abnormal climate events than the other sites. Based on the present study, we suggest that proper attention and conservation strategy should be provided to Himalayan fir growing in the moist temperate forests of Pakistan.

In a series of 51 circular research plots (size 500 m2), the biometric characteristics (tree species, diameter at breast height, height) of all the stems with a diameter above 8 cm were registered. From the selected stems, we collected 51 cross-sections and 178 tree cores in total and performed age and growth analyses. In addition, for the lower layer trees, we assessed the competition by the neighbouring stand quantified by the competition index. The results confirmed the differences in the age structure, despite the similar diameter distributions in the investigated stands, as well as the differences in the growth dynamics of the spruce and fir in the lower tree layer. Nevertheless, the competition of the neighbouring stand was not proven as a significant factor for the diameter growth of the lower layer trees.

Holmboe. (Anatolian black pine) seeds to salt stress Abstract: The germination stage, which is known to be the most sensitive period of plant development, is very sensitive to salt stress. To determine how salt stress affected the germination behaviour of Pinus nigra Arn. subsp. pallasiana (Lamb.) Holmboe, the seeds were germinated at gradually increasing salt concentrations. The detrimental effect of the salt stress increased parallelly to the salt concentration. The morphological and physiological changes were analysed in each application to detect the effect of the increasing salt concentrations on the germination stage, and the results were evaluated. The root and stem length, germination percentage, seed germination vigour index and seed mass decreased with the increasing concentration. The amount of volatile and phenolic compounds increased up to 100 mM of salt concentration, while similar parameters decreased at other salt concentrations. The gradual destruction of the habitats of these plants, which create sustainable living conditions with their ability to adapt to the ever-changing climatic conditions, and the increasing ecological negativities make it challenging for the quality of life and viability of these plants. The study was aimed at defining the responses to salt stress by examining the changes in the germination behaviour and phytochemical content, and the amount of Anatolian black pine seeds with an increasing soil salinity.
