Alpine and subalpine vegetation of Mt. Midzhur, Stara Planina, Bulgaria

This dataset contains data used in my diploma thesis. The fieldwork was carried out in the Western Stara Planina Mountains, mainly in the area of Mt. Midzhur. I recorded 78 vegetation plots using the Braun-Blanquet approach. The dataset was classified using modified Twinspan algorithm. A DCA ordination graph was created to present the dissimilarity of the vegetation types. The vegetation was divided into 12 classes. Seven alliances not previously known from Bulgaria and one newly described alliance of subalpine tall-herb vegetation on screes were reported. Numerous associations were newly reported for Bulgaria or were newly described. The role of altitude and soil pH on the vegetation was analyzed using the general linear model; the floristic composition was analyzed on the level of floristic elements.
