G. Matus; B. Tóthmérész; M. Papp Applied Vegetation Science 2003. doi:10.1658/1402-2001(2003)006[0169:rpoass]2.0.co;2
Other claims from this paper (11)
- Association Robinia invasion replaced most grassland species with nitrophytes.
- Association Vertical position influenced species abundance.
- Association Vertical position affected vegetation composition only moderately.
- Association Fine-scale vegetation zonation changed with time.
- Association Above-ground species richness was slightly greater at lower than higher sites.
- Association Soil seed density was slightly greater at lower than higher sites.
- Association Seed banks of sensitive grassland specialists disappeared during grass encroachment.
- Observation Some annuals and perennials surviving in above-ground vegetation retained seed banks.
- Association Many species lost from above-ground vegetation during Robinia invasion left viable persistent seeds.
- Recommendation Restoration after above-ground extinction must rely on dispersal from adjacent areas.
- Mechanism Competitive weeds and sprouting Robinia can limit seedling establishment.
