Vegetational surveys have been carried out starting from late summer 2015 in order to assess the site composition. The interpretation of vegetational data will be carried out taking into account the soil nutrients status.

Meteorological data of the LTER station Zöbelboden from the year 2012

Global radiation of Blaseneck, Oberkainz, Schröckalm, Kölblwiese, Zinödl, Weidendom and Gscheidegg.

The data are gathered within the TERENO (Terrestrial Environmental Observatories) long-term research programme involving several Helmholtz Association Centers in Germany (www.tereno.net). TERENO aims to catalogue the longterm ecological, social and economic impact of global change at regional and landscape level. The biodiversity part of TERENO deals with monitoring and research on different organism groups: (1) Vascular plants (primary producers, overall biodiversity indicators), (2) Bees &amp; Hoverflies (important pollinators; ecosystem service agents), (3) Butterflies (indicators for habitat quality, pollinators), (4) Birds (highly mobile, sensitive to landscape context, integrative at landscape scale).</p><p>This dataset covers bird count data of 4x4 km landscapes in Saxony-Anhalt (Germany) dominated by agricultural use. All singing, calling and seen birds were registered according to the point counts method described by Bibby et al. (1992): Bird census techniques, Academic press, London.

Global radiation of meteorological Station Rudolfshütte

Basic meteorologic data from authomatic weather station located at Fabra Observatory. Original data values registered at 10 min intervals and then averaged for daily data (mean or sum).

Meteorological data of the LTER station Zöbelboden from the years 2001 to 2011

Air temperature of Blaseneck, Oberkainz, Schröckalm, Kölblwiese, Zinödl, Weidendom and Gscheidegg.

Vegetational description of inner Venter-valley and outer Rofen-valley along an altitudinal gradient from 1695 m to 2865 m a.s.l. Vegetation records were made in plots according to minimum areal of Braun-Blanquet (1964) In sum, 229 vegetation records were made (one record=one plot). Also ecological indicator-values are given. Ten vegetation associations were recorded, altitude and aspect were the most important criteria for the determination of different vegetation types. GPS-data were taken from googlemaps, according to the study site given in the report (Diploma-project).

Mean, max and min daily air temperature and precipitation (sum) from the National Hydrometeorology network for the town of Sandanski
