Abbreviations:
| Category name: | Abbreviations: | Explanation: |
|---|---|---|
| 1 | 1 | vascular plants: indicator of extreme acidity, never found on weakly acid or basic soils; bryophytes: never above pH 5, often near or below pH 3 |
| 2 | 2 | between 1 and 3 |
| 3 | 3 | vascular plants: acidity indicator, mainly on acid soils, but exceptionally also on nearly neutral ones; bryophytes: mostly below pH 5, on soils poor in nutrients |
| 4 | 4 | between 3 and 5 |
| 5 | 5 | vascular plants: indicator of moderate acid soils, only occassionally found on very acid or on neutral to basic soils; bryophytes: mainly between pH 5 and pH 6 |
| 6 | 6 | between 5 and 7 |
| 7 | 7 | vascular plants: indicator of weakly acid to weakly basic conditions, never found on very acid soils; bryophytes: around pH 6 until pH 6.9 |
| 8 | 8 | between 7 and 9 |
| 9 | 9 | vascular plants: basic reaction and lime indicator, always found on calcareous soils; bryophytes: exclusively in the neutral to basic range, around pH 7 and higher |
