Effects of tree dieback on lake water acidity in the unmanaged catchment of Plesne Lake, Czech Republic
Original language description
Terrestrial exports of protons (H+), nitrate (NO3-), dissolved organic carbon including organic acid anions (A(-)), phosphorus (P), base cations, and ionic aluminum (Al-i) underwent pronounced changes after bark beetle-induced tree dieback (2004-2008) in a nitrogen-saturated, chronically acidified but recovering catchment, Plesne Lake, Czech Republic. After a short decline in lake water pH immediately after tree dieback, the ecosystem recovery from acidification accelerated and the carbonate buffering system was restored by 2011, after similar to 6 decades of depletion by acid rain. Major reasons for this rapid transition were changes in intensity of in-lake biogeochemical (H+ producing/removing) processes caused by changing concentrations and proportions of solutes exported from soil to surface water. In-lake denitrification, elevated NO3- assimilation (due to elevated P input), and photochemical/microbial oxidation of A(-) were the most important H+ removing processes, while Al-i hydrolysis was the most important H+ source. Phytoplankton biomass increased with elevated P inputs and increasing P availability, which resulted from reduced in-lake formation of Al hydroxide (and thus less adsorption of P) and more intensive P recycling by zooplankton. The rapidly changing lake water chemistry and elevated P availability after tree dieback in the catchment thus have enabled further biological recovery of Plesne Lake.
