A field trip to one of seven different
areas within the Czech Republic relevant to the conference topics will
provide a mid-conference break. The conference fee will cover a field trip to the Slavkov Forest (Slavkovsky les), Ore Mountains (Krusne hory), Jizera Mountains (Jizerske
hory), Giant Mountains (Krkonose), Eagle Mountains (Orlicke hory), Kosetice in
the Czech-Moravian Highlands (Ceskomoravska vysocina) or to the Bohemian Forest (Sumava) (see
the map).
All mid-conference field trips are scheduled for Wednesday, June 15. Departure
from Prague is planned at 8 a.m., arrival at 6 p.m. (field trips O, J, G, K) or 8
p.m. (field trips S, E, B). These seven mid-conference field trips are fully
covered by the conference fee.
Destinations of the One-Day Mid-Conference Field Trips
in
Bohemia - June 15
Following areas will be visited within the
field trips:
Slavkov
Forest (Slavkovsky les)
Twenty studied catchments underlain by several geochemically
contrasting bedrocks represent broad ecosystem sensitivity to acidification.
During the field trip the following sites will be visited: Lysina catchment (ICP
- Integrated Monitoring, GEOMON), Lazy plot (ICP - Forests), Stinker Natural
Reserve.
 Monitoring of the highly acidic stream water
during high-flow at the Lysina catchment.
Standing acidic surface water with effluents of gaseous H2S and CO2
generated by postvolcanic activities in the Stinker Natural Reserve.

Ore Mountains (Krusne hory)
During the field trip the following sites will be visited: Prunerov
power plant, Nacetin plot, Kopisty station (ICP - Materials)
 The Prunerov
thermal power-plant, one of the principal energy sources, in the
region of the so - called Black Triangle area (highly industrialized and
formerly highly polluted border zone between southern Saxony in Germany, Silesia
in SW Poland and Northern Czech Republic). In 1992, the Czech Power Company CEZ,
the major producer of electrical energy and heat in the Czech Republic launched
a programme of desulphurisation and modernization of power stations in order to
meet new legislation standards.
Some of the most severe spruce forest damage during the 1990’s was documented in
the winter of 1995/1996 (see photo) at the Nacetin forest plot. Since that time forest health has improved due to significant
declines of air pollution by SO2.
Monitoring of
acid deposition effects on corrosion of metals in the North Bohemian Coal Basin
at the station Kopisty (ICP-Materials international network).
Jizera Mountains (Jizerske hory)
The Jizera Mountains were subject to rapid and extensive deforestiation
predominantly caused by soil acidification. The first signs of spruce damage
were observed in late 1970s at highest altitudes and a large scale dieback was
completed during 1980s. In 1995, only young spruce trees remained on the plateau
of the Jizera Mountains. The view from the summit of the Jizera Mt. in 2004
shows partial recovery of forests on the upper plateau.

(1122 m a.s.l) in 1976

 Cerna
Desna stream (Uhlirska catchment) was without fish
since World War II until the beginning of the 1990s when spruce forest dieback
decreased acidic deposition and stream chemistry improved. Now brook trout (
Salvelinus fontinalis) inhabits the region and the fish population is endangered
by spruce monoculture re-plantation. Uhlirska catchment is a part of GEOMON and
ERB (European Research Basin) network.
Giant Mountains (Krkonose)
 The
Giant Mountains are a typical example of decline of high-altitude Norway spruce
stands due to long-term soil acidification and climatic stress. Snezka (1602 m a.s.l.) is the highest peak of the Czech Republic.
During the field
trip different gradual stages
of spruce forest dieback will be observed
at the
Mount Mumlava.
Eagle Mountains (Orlicke hory)
 The
Eagle Mountains received the highest sulfur
and nitrogen deposition in the country. Measured annual spruce throughfall was between
34-56 kg. ha-1 for sulfur and 48-82 kg ha-1 for inorganic
nitrogen during the period 2000-2003. The area was deforested during 1980 and
new young spruce plantations show typical symptoms of nutrient imbalances
despite intensive liming during 1980s and 1990s.
Kosetice, the Czech-Moravian Highlands (Ceskomoravska vrchovina)
 The monitoring site
is focused on background environment
pollution monitoring. The participation of the Czech Republic in international
monitoring programmes (EMEP, WMO/GAW) is one of the principal goals of the
observatory.
As a part of long-term activities the small catchment Anensky was established for measurement of
biogeochemical cycles in a low polluted rural forest lansdcape. The site belongs
to the Czech GEOMON and the international
ICP-Integrated Monitoring network of
catchments.

Bohemian Forest (Sumava)
During the field trip the following sites will be visited: Cerne Lake
and the Na Lizu catchment
 A
markedly acidified surface water body (Cerne Lake) in the Bohemian Forest, south
Bohemia, an ICP Waters monitoring site.
Dead Norway spruce (Picea abies) forest after the bark beetle (Ips typographus)
attack in the Bohemian Forest, south Bohemia.

Monitoring of water and chemical element fluxes in throughfall and runoff in
a forested catchment (Na Lizu) in the Bohemian
Forest, south Bohemia. This catchment is operated by the Institute of
Hydrodynamics and it is involved in the Czech GEOMON and the international ERB (European
Representative Basins) network of catchments.
Meteorological station near to the closing profile of the Na
Lizu experimental catchment.
