The Zöbelboden was established in 1992 as the only Integrated Monitoring station in Austria under the UN Convention on long-range transboundary air pollution (CLRTAP). In 2006 it became part of LTER Austria. The Zöbelboden covers a small forested catchment (90 ha) of a karstic mountain range (500 to 950 m above sea level) in the Kalkalpen national park. Monitoring and research is focussing on air pollution effects on forested catchments and its interaction with climate change. The Zöbelboden represents one of the best known karst catchments in Europe with long-term data series of the major components of its ecosystems. The Zöbelboden is managed by the Umweltbundesamt GmbH. Sampling of chemical specimen is done by local staff. Chemical analyses are carried out by the laboratory of the Umweltbundesamt in Vienna.

Purpose of Site :

LTER Zöbelboden is a small, well definable catchment of 90 ha in the National Park Kalkalpen in Austria. Material inputs, pollutants and nutrients via air and precipitation are measured as well as their effects on the ecosystem. Their behaviour within the ecosystem is studied in a comprehensive manner and effects are determined. With standardized methods the long-term trends of ecosystem water and element fluxes are studied. Outputs through surface waters and into groundwater are part of this work as are trends in biodiversity and effects of climate change. The the long-term data is used in the UNECE CLRTAP effects monitoring Networks (www.unece-wge.org/), in EMEP, and the national air pollution monitoring. LTER Zöbelboden is an important site within the Austrian LTER (www.lter-austria.at) network so that many research institutions use the site in their projects. Since 2017 LTER Zöbelboden is part of the Austrian research network for ecosystem effects of extreme climate events LTER-CWN (www.lter-austria.at/en/cwn-project/).

Biogeographical Region:

Geology:

The main rock type is Norian dolomite (Hauptdolomit), which is partly overlain by limestone (Plattenkalk). Due to the dominating dolomite, the watershed is not as heavily karstified as limestone karst systems, but showing typical karst features, such as conduits and sink holes. These conduits and sink holes provide pathways for rapid water flow and quick response times to water input at the soil-bedrock interface.

Hydrology:

The watershed can be divided into two distinct sites: A very steep (30 – 70°) slope from 550 – 850 m a.s.l. and an almost flat plateau (850 - 956 m a.s.l.) on the top of the mountain. The areal coverage of each site is 50 % of the watershed. At each site, intensive plots have been selected for comprehensive measurements of hydro-chemical variables. Intensive plot I (IP I) is located on the plateau where Chromic Cambisols and Hydromorphic Stagnosols are found. Intensive plot II (IP II) is located on the slope and dominated by Lithic and Rendzic Leptosols.

Vegetation:

The mean slopes are 14° at IP I and 36° at IP II. IP I is dominated by a Norway spruce (Picea abies) following plantation after a clear cut around the year 1910, whereas a mixed mountain forest with beech (Fagus sylvatica) as the dominant species, Norway spruce (Picea abies), maple (Acer pseudoplatanus), and ash (Fraxinus excelsior) covers IP II. After wind and bark beetle damage at IP I a third intensive plot (IP III) has been established in the year 2008 representing the plateau ecosystem. IP I is still used for studying the effects of disturbance on these ecosystems.

Soils:

Intensive plot I (IP I) is located on the plateau where Chromic Cambisols and Hydromorphic Stagnosols are found. Intensive plot II (IP II) is located on the slope and dominated by Lithic and Rendzic Leptosols.

Infrastructure

Infrastructure notes:

The Zöbelboden covers a small forested catchment (90 ha) of a karstic mountain range in the Kalkalpen national park. Meteorological and air pollution monitoring is carried out at a clearing area (EMEP station) and on a tower (45 m height). The tower is additionally equipped with an eddy corariance system for carbon dioxid and water vapor. One old and two new intensive plots exist for the detailed measurement of element fluxes through the main forest types (bi-weekly to monthly analyses of deposition and soil water). One plot is equipped with a sapflow system, automated dendrometers, and soil respiration chambers. Catchment runoff chemistry is measured at the main spring with an optical probe for high resolution data and through weekly sampling and analyses. On 64 permanent plots (regular 100 m grid) forest tree monitoring, ground vegetation and soil sampling is carried out (5 to 10 year interval). Additional permanent plots exist for forest floor vegetation, lichens, bryophytes and birds (3 to 10 year interval). The main stations (EMEP station, intensive plots, the hut) can be reached via a forest road with all year access (once a week in winter).The station has full power supply, a radio transfer of the data within the site and remote online access to the major devices.
