The first GLORIA Master Site dates back to 1994, when an extensive setting of permanent plots, arranged in transects across the alpine-nival ecotone was established at Mount Schrankogel in the central high Alps of Tyrol. These permanent plots were set up in response to evidence on upward shifts of alpine plants on high peaks of the Alps, reinvestigated in 1992 and 1993 (GOTTFRIED et al. 1994; GRABHERR et al. 1994, 2001; PAULI et al. 2001). The 3497m-peak Mount Schrankogel belongs to the highest mountains of the Austrian Alps. Its northern and eastern sides are surrounded by glaciers and glacier forelands. Its southern to western faces, however, are not interrupted by glaciers but show an altitudinal vegetation sequence characteristic for the central siliceous high Alps: from the lower-alpine zone, dominated by dwarf shrubs, to upper alpine Carex curvula-grassland, and finally to open and scattered nival vegetation on screes and solid rock. Around 1000 permanent plots of 1x1m², established in 1994, are distributed between 2900m and 3450m spanning across the alpine-nival ecotone from the upper margin of closed alpine grassland to the nival zone. Positions of the corner points of each quadrat were accurately surveyed using a tachymeter and photographs were made from each plot. Percentage cover of all vascular plant species and total percentage cover of bryophytes and lichens as well as the cover of abiotic surface components were recorded. Further, a Digital Elevation Model of 1x1m-resolution, covering the entire study area, was generated. Between 1994 and 2006, a number of additional studies were added to the extensive basic dataset of Schrankogel:
Besides an area-wide vegetation mapping (ABRATE 1998; DULLINGER 1998) and a description of subnival to nival plant assemblages (PAULI et al. 1999), model studies on vegetation distribution and patterns in relation to the macro- and micro-relief and micro-climate were conducted (GOTTFRIED et al. 1998; GOTTFRIED et al. 1999, 2002). Based on these studies, scenarios of future distribution patterns of keystone species were developed. Further, the influence of domestic and wild-living ungulates (ERTL et al. 2002; Hülber et al. 2005), nitrogen gradients (HUBER et al. 2007), permafrost patterns (HAEBERLI et al., unpubl.), flowering phenology and photoperiodism of alpine and nival vascular plants (KELLER & KÖRNER 2003; Hülber et al. 2006, 2010), as well as patterns of bryophytes (HOHENWALLNER et al. 2011) were investigated. Soil T at Schrankogel is measured at around 60 positions distributed over the mountain's southern slope system since 1997 on an hourly basis. A major resurvey in 2004 showed both increases of vascular plant species richness as well as declines in species cover of all subnival-nival species (Pauli et al. 2007). Conicidence in the position of the alpine-nival ecotone was found as well as an upward shift was indicated by comparing summer-snow data of the Eastern Alps and Schankogel vegetation data (Gottfried et al. 2011). In 2009, two remote cameras were installed to monitor the snow pattern on the slope system and cushion plant surveys were conducted (Nießner 2011, Prohaska, 2011). In 2014 the third major permanent plot resurvey is planned.
