variable humidity |
A situation where a species appears to occur in a range of soil humidity as derived from accounts; this may either because soil humidity has little ecological bearing on the species ecology, or that the account generalisation obscures the real humidity niche utilised. |

variable base status |
Associated with sites of varying underlying geology and pH level. |
