AbstractThe Bohemian Forest (Šumava, Böhmerwald) is situated in Central Europe and is among the most acidified lake districts in the world. Deposition of S and N compounds in the area rapidly increased between 1950 and 1980, and reached a maximum in the 1980s. During the 1990s, acid deposition decreased substantially, and current levels are comparable to the early 20th century for SO42− and NH4+, and to the mid 1960s for NO3−. These changes in acid deposition have led to a partial recovery of the Bohemian Forest lakes. This paper provides an overview of previous research, and details on the organization and aims of current research on the Bohemian Forest lakes. Available historical data and regular monitoring (since 1984) provide a valuable background for long-term ecological research of the catchment-lake ecosystems that currently focuses on (i) chemical reversal and biological recovery of the lakes, (ii) acidification impacts on in-lake nutrient cycling, (iii) climatic effects on water chemistry, and (iv) catchment processes, including soil biogeochemistry and acidification impacts on vegetation.

AbstractWe studied water chemistry and phytobenthos in streams of the Bohemian Forest (Šumava, Böhmerwald) in order to determine the influence of sewage originating from recreational usage on the diversity and structure of periphytic assemblages. Sites both above and below the outflow of sewage from touristically exploited villages and small recreational centres were compared. All together, we identified 113 species of algae and cyanobacteria in the samples, including very rare species such as Clastidium setigerum (Cyanobacteria). In some streams, waste discharge increased the concentration of nutrients to a marked degree. Species richness of phytobenthos was correlated neither to nutrient concentration nor to algal growth potential. However, an increase in chlorophyll-a, and a shift in the structure of phytobenthos assemblages were observed at sites below the source of pollution. At the most polluted sites Chlorophyta (e.g., Pseudodendoclonium basiliense, Chlorosarcina sp.) dominated, and Bacillariophyceae species sensitive to pollution were replaced by tolerant ones (Cymbella minuta, C. caespitosa, Diploneis oblongella and Nitzschia spp.).

AbstractThis paper evaluates the total biomass and pools of major nutrients and ecologically important metals of the tree layer in the catchment of Plešné jezero (PL) in the Bohemian Forest (Šumava, Czech Republic), and compares them to analogous data on understory vegetation and soils. The results are based on field measurements and semi-automatic image analyses of aerial orthophotographs. The tree layer was relatively sparse with open canopy in some parts of the catchment. Stand density varied between 44 and 328 individuals per hectare. The catchment weighted mean total biomass of trees was 134 t ha−1 dry weight, of which needles, branches, roots, and stems represented 5%, 10%, 14%, and 71%, respectively. The stem wood and bark represented 67% and 4%, respectively, of the total tree biomass. The catchment weighted mean element pools were 568 and 3.0 mol m−2 (i.e., 68 and 0.42 t ha−1) for C and N, respectively. The other pools were 76 mmol P m−2, 602 mmol Ca m−2, 133 mmol Mg m−2, 39 mmol Na m−2, 347 mmol K m−2, 19 mmol Al m−2, 6.2 mmol Fe m−2, and 35 mmol Mn m−2. The element pools accumulated in the tree biomass represented from < 1% (Al, Fe) to 37% (C) of their total pools (soil + tree layer + understory vegetation) in the catchment. Pools of Ca and Mg in the tree biomass were similar to their exchangeable pools in the catchment soils, while those of K were 3 times higher. Nutrient (N, P, Ca, Mg, and K) and C pools in the tree biomass were 2–11 times higher than those in the understory vegetation, with the minimum for P and maximum for C.
