Methods

"This dataset is a subset of two. Data contained here is from the 500m2 circular plots described below. On each LWF monitoring site (usually 2 hectares in size), ground vegetation is surveyed following two methods: 1) phytosociological relevés were made in one or two circular 500 m2 plots, with estimation of abundancedominances of all species in the moss and herb layers using the Braun-Blanquet scale (Braun-Blanquet 1964), which was later on converted into percentages. Species cover (in percent) was assessed in  16 1x1m2 vegetation quadrats systematically distributed within a 43mx43m intensive monitoring subplot 2) relevés of species cover (percentage) in 16 1x1m2 vegetation quadrats, located in a 43mx43m intensive monitoring subplot within the LWF monitoring site. Only mosses growing on soil were recorded. The cover of all species belonging to the moss, herb (height<= 0.5 m), shrub (0.55 m) was visually estimated in %. The first surveys took place in 1995, data are provided until survey year 2011. Until 2003 (included), the heights of the layers were defined dynamically and the maximum height was reported. In 2011, the heights of the layers were fixed (herb layer: <=0.5 m, shrub layer: 0.5
