Source of data
Zelený & Li (2008), Zelený (unpubl.)
Description of dataset
Vegetation samples of acidophilous grasslands (16-25m2) recorded in 2004-2007.
Locality
North of Třebíč city, Czech Republic. Grasslands typically occur on convex topography with shallow soils, and form “islands” (habitat patches) of acidophilous vegetation in otherwise intensively manages agricultural landscape.
