Forest vegetation data from Vltava river valley

Source of data

Zelený & Chytrý (2007)

Description of the dataset

Distribution of plots along transects across the valley.

Vegetation plots, located at even distances along transects following the steep valley slopes of Vltava river valley, collected during 2001-2003. Each transect starts at the valley bottom and ends up at the upper part of the valley slope. Altogether 97 plots located in 27 transects were collected, each of the size 10×15 m. In each plot, all tree, shrub and herb species were recorded and their abundances were estimated using 9-degree ordinal Braun-Blanquette scale (these values were consequently transformed into percentage scale). At each plot, various topographical and soil factors were measured or estimated.

Locality

Vltava river valley close to Zlatá Koruna, Český Krumlov, Czech Republic. The transects follow the slopes of various aspect, and only the sites with natural or semi-natural forest vegetation were selected (no forest plantations).
