11vascular plants: indicator of extreme acidity, never found on weakly acid or basic soils;
bryophytes: never above pH 5, often near or below pH 3
22between 1 and 3
33vascular plants: acidity indicator, mainly on acid soils, but exceptionally also on nearly neutral ones;
bryophytes: mostly below pH 5, on soils poor in nutrients
44between 3 and 5
55vascular 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
66between 5 and 7
77vascular plants: indicator of weakly acid to weakly basic conditions, never found on very acid soils;
bryophytes: around pH 6 until pH 6.9
88between 7 and 9
99vascular plants: basic reaction and lime indicator, always found on calcareous soils;
bryophytes: exclusively in the neutral to basic range, around pH 7 and higher
