Information

Ecological parameter:  saprobity

Parameter group: saproby related parameters

Explanation:
The parameter provides information on the tolerance of a species to readily organically degradable substances. The proven system of saprobic valences of Zelinka & Marvan (1961) is used, in which the species are divided into 5 saprobic levels. Additionally, the saprobic index of the species and the indication weight are given. The parameter includes classifications from various European countries.

Classification system: 10 point assignment system
