Site Description
The Bohemian Forest in Central Europe is among the most acidified lake districts in the world. Deposition of sulphur and nitrogen compounds in the area rapidly increased between 1950 and 1980, and reached a maximum in mid the 1980s. Owing to long-term occasional hydrobiological research and palaeolimnological studies, we are able to document the significant changes in the lake water chemistry and biodiversity (in particular the conspicuous reduction in crustacean and/or insect species in some lakes, as well as the extinction of fish). During the 1990s, acidic deposition decreased substantially, and its current levels are comparable to the early 20th century for SO42– and NH4+, and to the mid 1960s for NO3–. The decline in acidic ...

Vegetation
The catchments weighted means of above-ground biomass of the understory vegetation (mostly Vaccinium myrtillus and Calamagrostis villosa) were 723 and 288 g m?2 in the PL and CT catchments, respectively, in 2004. Forest is dominated by mature Norvay spruce Picea abies), which was seriously damaged by a bark beetle (Ips typographus) outbreak during 2004-2006.
Soils
Catchment of Certovo Lake is covered with ~0.5 m deep spodo-dystric cambisol (58%), podsol (21%), and shallow (~0.2 m) leptosol (17%); wetlands and bare rocks represent ~3% and 1%, respectively. Catchment of Plesne Lake is covered with ~0.2 m deep leptosol (38%) and ~0.45 m deep podsol (29%) or spodo-dystric cambisol (27%); the rest is bare rocks (5%) and wetlands (~1%).
Hydrology
Specific outlet: Catchment of Certovo Lake: 25-64 (42 on average) l/km2/s in 1998-2011. Catchment of Plesne Lake: 23-57 (35 on average) l/km2/s in 1998-2011.
