Vegetation surveys on dike grasslands between Straubing and Vilshofen at the river Danube - Sites

Description: We surveyed dike grasslands of the river Danube between 2017 and 2021 with 41 plots (25 m²) at 12 sites. The dike grasslands had an age of 4-19 years. The dikes were raised and restored. The target vegetation types were calcareous grasslands (R1A; EUNIS habitat type) and lowland hay meadows (R22). We measured local site characteristics like soil samples, landscape factors and historical factors.
