“…However, the Mn concentration changes in the MKB and VH subsets during the summer months (July–September) were considerably less significant than those reported by Wildová et al ( 2021 ). In the VH and MKB subsets, the median MAD/median values (equivalent to the average relative deviation) for individual trees or tree branches were only 4.7% and 5.0%, respectively, and the maximum values for individual trees were evenly distributed over the summer period.…”

“…Similar to previous studies (Wildová et al 2021 ; Bílková et al 2023 ), the leaves were sampled without washing in paper bags. The concentrations of the target elements in the leaves were high because of their accumulation relative to the soil (Reimann et al 2007a , 2007b ), and traces of soil or dust could not contaminate them, as discussed by Bílková et al ( 2023 ).…”

“…Furthermore, certain common European tree species, including the silver birch ( Betula pendula Roth) and downy birch ( B. pubescens Ehrh. ), show Mn FECs exceeding Mn concentrations in soils (Reimann et al 2001 , 2015 , 2018 ; Wildová et al 2021 ; Bílková et al 2023 ) up to levels that are potentially harmful to these species (Hrdlička and Kula 2004 ; Bílková et al 2023 ). However, the reason for this high Mn accumulation in birches is unknown.…”

“…Accordingly, Alejandro et al ( 2020 ) and others (Gilliam et al 2018 ; Zemunik et al 2020 ; Bílková et al 2023 ) considered Mn uptake by plants to be understudied. The high tolerance of birch trees to excess Mn (Wildová et al 2021 ) renders them particularly suitable for large-scale studies on factors promoting Mn uptake by plants in nutrient-poor and degraded soils.…”

In Central European mountain forests, foliar element concentrations (FECs) of manganese (Mn) in silver birch (Betula pendula Roth) are occasionally approximately 5000 mg kg−1 and can represent stress for these plants. Factors controlling the Mn FECs in silver birch in Central Europe and downy birch (Betula pubescens Ehrh.) in Norway have not yet been fully deciphered. In this study, the Central European silver birch specimens were sampled in 2022. The samples were analysed by X-ray fluorescence spectroscopy. Norwegian data were obtained from the literature. Mn FECs are commonly negatively correlated with magnesium and, in certain areas, with potassium. Mn FECs are simultaneously elevated with zinc (Zn), likely because of soil acidification and anthropogenic emissions. Mn FECs in birch were previously thought to be related to altitude, which was assigned to (i) downslope washes of Mn or (ii) the historical load of acid emissions. The highest Mn FECs in silver birch were found in the Harz Mountains, Germany, and have been attributed to historical atmospheric contamination and the abundance of soils on felsic silicic rocks poorly buffering acid rains. The historical emission load from iron and steel production was hypothesised to be the cause of elevated Mn and Zn FECs in the Beskid Mountains, Czech Republic. Mn FECs in birch can be used to map historical soil acidification caused by industrial emissions. Zn FECs in birches can reflect soil contamination by this element.

“…Birch is one of the most common tree species in the study area [17] and in other temperate and boreal European forests. Previous studies in the Ore Mountains attributed the high Mn concentrations in the foliage of forest plants exclusively to industrial emissions [18,19] . This conclusion needs critical evaluation, because interelement relationships in soils and plants and the impact of bedrock geology have not been studied yet, although bedrock geology is known to affect the response of soils and surface waters to acid rain [4,20].…”

Manganese concentrations in silver birch leaves were studied in the Ore Mountains and several reference localities in Czechia, both mountainous (up to 950 m MSL) and lowland (ca. 300 m MSL). The studied mountainous areas have been seriously damaged by acid rains in the last decades and forests there have still not recovered from that crisis. The aim of this study was to identify the major controls on the foliar Mn concentration variability, which was more than one order of magnitude, from 200 mg kg -1 (10th percentile) to 2000 mg kg -1 (90 th percentile) in the mountainous sites, that is, under uniform environmental conditions and for the same emission history of mountainous forests. The foliar Mn concentrations in the highest 5% samples were >3000 mg kg -1 which can be close to toxicity for persistent tree growth and thus indicate actual local geochemical stress in plants. Manganese uptake by plants has been enhanced by acid rain in the last decades, inferred from low foliar Mg (ca. 0.15%) and soil acidity (soil pH down to 4.0 in aqueous extracts). Certain bedrocks in the Ore Mountains, particularly local granitic porphyry and mafic lavas, have elevated Mn concentrations; however, in the mafic lavas, the soil Mn excess is compensated by elevated concentrations of soil Mg and pH. The highest foliar Mn concentrations were found in specimens growing in soils on granitic porphyry and on certain granites. The Mn concentration in birch leaves could be proposed as a proxy for the impact of soil acidification in central European mountain forests.

Alnus glutinosa is an actinorhizal plant that fixes N via actinomycetes. Compared to other trees, A. glutinosa is more resistant to environmental stress and able to uptake soil nutrients more easily. Alnus glutinosa grows well not only in natural stands but also in degraded environment or soil in need of restoration. Changes in the contents of selected macro-, micro-, and non-nutrient elements in the leaves of A. glutinosa during the vegetation season were monitored in the Ore Mountains (Czech Republic), an area affected by extreme air pollution in the past. Decreased foliar content of N, P, K, and Cu, and increased content of Ca, Mn, Zn, and Al were observed; the content of other elements (S, Mg, Pb, and Cd) varied during the growing season or remained constant. From the viewpoint of nutrition, the content of N, S, Ca, and Mg macroelements was adequate; concentrations of P and K were low. Excessive amounts of Mn and Zn were measured, and the level of Cu was good. Non-nutrient elements Pb and Cd were present at the background level, and the level of Al was high. N/P, N/Ca, N/Mg, and Ca/Mg ratios were balanced, S/N value showed the lack of S, and N/K ratio indicated low content of K, which caused also suboptimal K/Ca and K/Mg values. The P/Al ratio varied from balanced to lower values. The content of individual elements and monitored changes were influenced by the amount of elements in the soil, moisture conditions, foliage phenology, and altitude.
