During the long-term monitoring project in Obergurgl, the aboveground phytomass of vegetation at four study sites was collected in the year 2005. The project was established in 2000, with the aim to record vegetational development in subalpine to alpine altitudes in aspects on the effect of grazing and grazing exclosure. Phytomass-data regards to a study site at Schoenwieskopf and three bogs in the Rotmoos-Valley. Aboveground phytomass was recorded by cutting the sod with sissors. The sod was cutted close to the soil surface in areas of 25x25 cm, next to the existing permanent plots per study site. On each study site, 24 areas were collected. 12 within the established fenced, 12 outside the fences in the control area. The sod was then splitted in fractions: grasses, herbs and cryptogams. The phytomass was then dried in a compartment drier, 24 hours with 80°C. Then, dry weight was measured out.

In the Biosphere Reserve Gurgler Kamm near Obergurgl (Central Alps, Tyrol, Austria) multi factorial experiments were carried out in the lower alpine zone from 2005 to 2007 to investigate the effects of simulated trampling, seed addition, and a combination of these two treatments. Permanent plots of 1 m² were established within (= exclosures) and outside (= controls) of fences at three peat bog sites and in a Nardus stricta-community at about 2300 m a.s.l. In autumn 2005 the following treatments were performed in the exclosures and controls, respectively: - artificial gap creation, - sowing of seeds collected in the study area and in the surrounding, - a combination of gaps x sowing.

The data set provides information about the relationship between abiotic and biotic environments on the ecosystem scale whereas the extensity is correlated by the intensity of effective factors of structural and functional change. Available data comprise element cycling and water relationships on the one hand and the dynamics of effective concentrations mainly in the soil solution. Supplementary data are values for characterizing ecosystem structures and the related element pools as well as climate.
