The alpine site is located in East Styria, the current stand is a Norway spruce monoculture. Measurements were begun in 1990. Primary research questions center around the lack of natural regeneration of all tree species and slow stand growth. The site is instrumented with climate stations, on-line measurements of plant-available light and soil temperature measurements. Data from two detailed inventories on tree rejuvenation, humus form distribution and ground vegetation are available as well as soil chemical analyses, LAI measurements and detailed humus form descriptions, litter analyses and litter input measurements. At the site two national and one international project have taken place.
