“…Plant community changes may contribute significantly to the chemistry of surface water as plants play an important role in the weathering processes and element cycling of the ecosystems (Wohl, 2017). As relationships between plant community changes and water chemistry are wellunderstood in the temperate climate zone (Flum and Nodvin, 1995;Likens, 1999;Nédeltcheva et al, 2006;Sajdak et al, 2021), they are relatively poorly understood in cold environments, as chemical weathering has been postulated to play a minor role for a long period of time (Peltier, 1950;Dixon and Thorn, 2005). However, Rapp (1960) was the first who noted the importance of chemical denudation in cold regions.…”

The study determines the differences in the chemistry of small headwater streams located in areas with different plant communities in Finnish Lapland. Water samples from 76 catchments with four different plant communities were collected and analyzed. The statistical analyses of water temperature, water specific electric conductivity and the concentration of main ions, revealed the greatest variation in ion concentrations related to rock weathering: Ca 2+ , Mg 2+ , HCO 3 in the studied catchments. Enrichment of water with these ions occurred in catchments representing forest communities with thick soils, especially in the boreal forest community. This suggests that future changes in the northern treeline may affect the surface water chemistry depending on the direction of changes. In case of the expansion of the treeline to the north due to climate warming, an increase in water mineralization and a shift of hydrochemical facies towards a Ca-Mg-HCO 3 -type can be expected. On the other hand, the regression of the northern treeline could be expected to result in a reduction of nutrient pools and leaching them into streams. Eventually, it could result in the depletion of soils and the dominance of atmosphere-derived ions in waters, and the hydrochemical facies will shift towards Na-Cl-type.

“…DOC dynamics are affected by complex processes, multiple environmental factors, and also anthropogenic disturbances. As a common strategy of forest management, deforestation (clearcut or selective) is an ongoing widespread phenomenon in Europe (Sánchez-Robles et al, 2022), and it exerts a strong effect on hydrological and hydrochemistry processes (Sajdak et al, 2021). Many studies have reported the change of DOC concentrations after clear-cutting (Schelker et al, 2012(Schelker et al, , 2014Drake et al, 2019).…”

Deforestation has a wide range of effects on hydrological and geochemical processes. Dissolved organic carbon (DOC) dynamics, a sensitive environmental change indicator, is expected to be affected by deforestation, with changes in atmospheric sulfur (S) deposition compounding this. However, how precisely anthropogenic disturbance (deforestation) under a declining atmospheric S input scenario affects the underlying spatiotemporal dynamics and relationships of river DOC and sulfate with hydro-climatological variables e.g., stream water temperature, runoff, pH, total dissolved iron (Fetot), and calcium (Ca2+) remains unclear. We, therefore, examined this issue within the TERENO Wüstebach catchment (Eifel, Germany), where partial deforestation had taken place in 2013. Wavelet transform coherence (WTC) analysis was applied based on a 10-year time series (2010–2020) from three sampling stations, whose (sub) catchment areas have different proportions of deforested area (W10: 31%, W14: 25%, W17: 3%). We found that water temperature and DOC, sulfate, and Fetot concentrations showed distinct seasonal patterns, with DOC averaging concentrations ranging from 2.23 (W17) to 4.56 (W10) mg L–1 and sulfate concentration ranging from 8.04 (W10) to 10.58 (W17) mg L–1. After clear-cut, DOC significantly increased by 59, 58% in the mainstream (W10, W14), but only 26% in the reference stream. WTC results indicated that DOC was negatively correlated with runoff and sulfate, but positively correlated with temperature, Ca2+, and Fetot. The negative correlation between DOC with runoff and sulfate was apparent over the whole examined 10-year period in W17 but did end in W10 and W14 after the deforestation. Sulfate (SO4) was highly correlated with stream water temperature, runoff, and Fetot in W10 and W14 and with a longer lag time than W17. Additionally, pH was stronger correlated (higher R2) with sulfate and DOC in W17 than in W10 and W14. In conclusion, WTC analysis indicates that within this low mountainous forest catchment deforestation levels over 25% (W10 and W14) affected the coupling of S and C cycling substantially more strongly than “natural” environmental changes as observed in W17.
