Recovery from Acidification in Central Europe ? Observed and Predicted Changes of Soil and Streamwater Chemistry in the Lysina catchment, Czech Republic

Popis výsledku v původním jazyce

The geochemical model MAGIC was applied to estimate streamwater and soil chemistry between 1851-2030 at the Lysina catchment, an acid-sensitive granitic catchment covered by planted Norway spruce monoculture in the western Czech Republic. Although SO2 emissions in the region declined by 90% compared to the 1980´ s, acidification recovery was small within the period 1990-2000. Stream pH increased only slightly (from 3.92 to 4.07), although SO4 concentration declined sharply. According to the MAGIC prediction using deposition measured in 1999-2000, streamwater pH will increase to 4.3 and soil base saturation to 6.2% by 2030 (from 5.7% in 2002). Pre-industrial pH was estimated to be 5.5 and soil base saturation 24.7%. Intensive forestry was responsible for approximately one third of the net base cation loss via accumulation in harvested biomass. Severely damaged sites, under pressure from forestry, will not return to a good environmental status in the near future.
