“…Therefore we conducted the response-function analysis only for the present year that supported the results of correlation analysis by identifying the precipitation, the SPEI and the REW of June as the most significant (Figure 8). In general, our results correspond to other studies describing spring/summer moisture availability as the main climatic driver of Pinus nigra growth in the Mediterranean [65][66][67][68][69][70][71][72].…”

This paper analyses the recent recurring dieback and growth decline of Black pine (P. nigra Arn. var austriaca) in the Keszthely mountains of south-west Hungary, and their relations to water deficits due to droughts. These relations were studied in five stands with low soil water storage capacity for the period 1981-2016. The vitality was assessed using 60 tree-ring samples and changes in remotely sensed vegetation activity indices, i.e., the normalized difference vegetation index (NDVI) and the normalized difference infrared index (NDII). Water deficit was estimated by using meteorological drought indices such the standardized precipitation-evapotranspiration index (SPEI) and the forestry aridity index (FAI), as well as the relative extractable water (REW), calculated by the Brook90 hydrological model. Results revealed a strong dependency of annual tree ring width on the amount of water deficit as measured by all the above estimators, with the highest correlation shown by the summer REW. Droughts also showed a long-term superimposed effect on tree growth. NDII seemed to be more sensitive to drought conditions than NDVI. The robust dependency of tree growth on the summer water availability combined with the projected increasing aridity might lead to decreasing growth of Black pine in Hungary towards the end of the century. We thus argue that the suggestion by several papers that Black pine can be a possible substitute species in the Alpine and Mediterranean region in the future should be revisited.

“…This stress was confirmed in this study for P. nigra seedlings. P. nigra is a drought sensitive species, showing a negative tree growth trend highly correlated with increased temperature and drought in summer (in the Eastern Mediterranean [36], but in Hungary as well [37]). The results of this study showed that the exposure to moderate heat (45 • C) and short drought did increase damage to seedlings for both contrasting provenances (Grevena and Šargan), but without significant difference between them.…”

To meet the restoration and reforestation goals in the changing environment, the translocation of genotypes and species northward and upward need to be considered to a great extent. Pinus nigra is a genetically diverse, drought sensitive species, with cold hardiness comparable to other tree species under the same climatic conditions. This study tested frost hardiness (whole plant freezing test—WPFT, and electric conductivity—EC test), and heat tolerance (heat tolerance test) of P. nigra seedlings from two southern Greek provenances (Kalamata and Grevena) and one northern Serbian provenance (Šargan) to better understand the potential of seed transfer from the south to the north of the species distribution in the Balkan peninsula. The results showed that, that for all studied provenances, the damage was great; the index of injury (Ii) at −18 °C was ranged from 49 to 54.5 (measured by the EC method) and the percentage of injured tissues ranged from 80–90% (measured by visual observation). For all studied provenances, a sharp increase in damages was observed with the fall of temperature from −5 and −18 °C and the time after exposure. The WPFT results showed that the highest tolerance to freezing (−18 °C) was presented by seedlings from the northern (Šargan) provenance; however, no significant differences were statistically detected among the studied provenances. The heat and drought-treated seedlings, from both provenances, presented significantly highler foliar damages than only drought-treated ones. For seedlings from both contrasting provenances (Grevena and Šargan), exposure to moderate heat (45 °C) and short drought did present damages but without significant difference between them. Considering freezing and heating tolerance, Greek provenances of P. nigra (i.e., Grevena region) can be successfully used in Serbian forestation and restoration programs. The present study makes a contribution towards P. nigra reforestation with practical implications for abiotic stress (frost, heat drought) tolerance among southern and northern provenances and could be valuable to determine the suitable provenances for reforestation programs and assisted population migration under climatic change scenarios.

“…Moreover, it was reported in another study conducted in Eskişehir (Türkmendağı) locality that elevation was the dominant environmental factor that increased the productivity of the species and the site index increased especially in areas where precipitation increased in the most arid three months in summer period (Oğuzoğlu and Özkan, 2015). In another study conducted in recent years, it has been determined that the productivity of black pine has decreased after the 1970s in the Mediterranean basin, which is one of the most sensitive regions to climate change (Janssen et al, 2018). It is stated that this situation is related to increasing summer temperature and drought in the region as a result of climate change trends in recent Gülsoy -Cinar: years.…”
