General Site Description: 

The site is located next to Wettingen in the canton of Aargau, within a natural, mixed forest stand which mainly consists of 150 year-old beech (Fagus sylvatica) and 120-170 year-old spruce (Picea abies) trees. Among others, the site is equipped with two meteorological measurement stations; one is located within the forest stand, the second is co-located in the nearby open-field, allowing to measure the forest stand effect on micro-climate. The following parameters are being measured since 2013: Soil solution chemistry (lysimeters), TREENET, atmospheric deposition (throughfall and bulk deposition), circular vegetation plots, crown condition assessment, diameter and height measurements, foliar analyses, leaf area index (LAI), litterfall, manual circumference band measurements, Ozone visible injury assessment, permanent vegetation quadrats, phenological observations, sapflow measurements, soil matrix chemistry, tree core sampling, automated point dendrometer measurements, automatic circumference band measurements.

Purpose of Site : 

The forest site "Laegeren" has been installed in 2012 as part of the Swiss Long-term Forest Ecosystem Research Programme LWF (WSL) and FluxNet (ETHZ). The programme investigates anthropogenic and natural forces on the long-term health of the forests and the potential risks to humans. For this, a profound understanding of the relationship between processes, causes and effects in the ecosystem are necessary. The objectives of the LWF research programme include (i) early detection and a representative assessment of changes in forest condition, (ii) determination of external influences, both from anthropogenic and natural sources such as element inputs and climate and their effect on the forest ecosystem, (iii) development of indicators to assess the condition of the forest, (iv) integrated risk assessment based on different stress scenarios, and (v) extended platform for internal and external research projects. The research site Laegeren offers a unique combination of ongoing long-term forest monitoring and eddy covariance measurements of regional climate (since 2004), CO2 and microclimate profiles through the forest incl. soil temperatures and soil water potentials, tree physiological records such as sap flow and continuous stem radius changes and multiple properties of the vegetation (e.g. crown transparency, litter-fall, rain depositions) and soil structure. The LWF research programme provides, on the one hand, long-term data series from the last 20 years, together with a scientific interpretation to national and international policy makers. On the other hand, the available data and latest LWF infrastructure provide an attractive scientific platform for collaboration with both national and international partners.
