Grades – what do they mean?

Ecosystem Health Report Card Grades ('A' to 'F') are generated for a number of catchments and estuaries in South East Queensland and Moreton Bay. Parameters for freshwater, estuarine and marine ecosystems are assessed against guidelines resulting in the determination of a single grade for each system.

Excellent

Conditions meet all set ecosystem health values; all key processes are functional and all critical habitats are in near pristine condition.

Good

Conditions meet all set ecosystem health values in most of the reporting region; most key processes are functional and most critical habitats are intact.

Fair

Conditions meet some of the set ecosystem health values in most of the reporting region; some key processes are functional and some critical habitats are impacted.

Poor

Conditions are unlikely to meet set ecosystem health values in most of the reporting region; many key processes are not functional and many critical habitats are impacted.

Fail

Conditions do not meet set ecosystem health values; most key processes are not functional and most critical habitats are severely impacted.
