Species richness in dry grassland patches of eastern Austria: A multi-taxon study on the role of local, landscape and habitat quality variables

- Historical patch size is a better species richness predictor than current size.
- Habitat quality variables are better predictors than size variables.
- High quality areas in the landscape are more important than extensively used areas.
- Grassland specialists do not benefit from linear structures in the surroundings.
- Conservation should achieve a network of high-quality grassland patches.
