Ecological parameter: geochemical imprinting

Parameter group: habitat related parameters

Explanation:
Describes the focus of distribution of a species with respect to its geochemical character. The focus of distribution is indicated in the pH spectrum.

Type of assignment: presence/absence assignment system ()
