Other claims from this paper (7)
- Observation 39 plant communities of Estonian inland sand knobs were described and classified into 7 syntaxonomic units.
- Association Litter cover and the total cover of field and moss layers are the environmental variables determining the variation structure of the samples.
- Association Species richness of the communities depends mostly on the amount of litter.
- Observation 415 quadrats of the sand knob vegetation were clustered into 23 microcoenose types.
- Observation The most frequent microcoenoses are those of Cladina arbuscula with Pycnothelia papillaria, Festuca ovina, or Festuca ovina with Pilosella officinarum.
- Observation Microcoenoses of any type are confined to only one type of plant community.
- Recommendation To maintain the features of Estonian inland sand knob plant communities, they must be kept open and the dense bottom layer vegetation removed in some places.
