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.\r\n\r\nThe 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. \r\n\r\nThe 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.\r\n\r\nThe site is located next to Alpthal in the canton of Schwyz, within a natural, coniferous forest stand which consists of 180-230 year-old spruce (Picea abies) trees. \r\nAmong 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.\r\nThe following parameters are being measured (starting-end year): atmospheric deposition (1996-1998), circular vegetation (1995-today), crown condition (1995-today), Deadwood survey (1995,2005), diameter and height (1999-today), foliar analyses (1995-today),  leaf area index (1996-today), lichens (2003-today), litterfall (1996-1998), manual circumference band (2001-today), matric potential (1997-1999), meteorological parameters (1997-today), ozone injuries (2002-today), ozone visible injury assessment (2002-today), passive sampling of O3 (2002-2004), Phenological observations (1995-1998), soil matrix chemistry (1998-today), soil morphology (1998-today), tree core sampling (1791-1998), tree crown measurements (1995-today), deadwood sampling (2009). \r\n","citation":null,"relatedIdentifiers":null,"status":{"label":"Operational","uri":"http:\/\/vocabs.lter-europe.net\/elter_cl\/10772"},"yearEstablished":1995,"yearClosed":null,"relatedSites":null,"siteName":"Alptal","shortName":"ALP","siteType":"Stationary land-based site","protectionLevel":null,"landUse":null,"images":[{"url":"https:\/\/deims.org\/sites\/default\/files\/2021-10\/alptal_01_0.jpg","alt":"The valley Alptal seen from Mythen.
