River reaches are prioritised for management or intervention according to condition, recovery potential and spatial relationships to other reaches which may affect, or be affected by, processes operating in adjacent reaches. This field has been updated for some catchments when the most recent River Styles assessment was completed. Other catchments have been updated using calculations in ArcGIS based on stream condition, recovery potential and connections to other reaches.
Intact Geomorphic condition - Good Rate of recovery or presently occurring - No recovery occurring or required. Has not been recently disturbed or has fully recovered from past disturbances. Sediment, seed or large wood input - Appropriate for the River Style. None.
High Priority Geomorphic condition - Moderate Rate of recovery or presently occurring - Quickly if existing pressures are removed and connected to good condition upstream reaches. Or at moderate rate if disconnected to good condition upstream reaches. Sediment, seed or large wood input - May have sediment, seed or large instream wood (if required) input depending on upstream reaches. Excess sediment supply - Small sediment slugs.
Moderate Priority
Geomorphic condition - Moderate to poor Rate of recovery or presently occurring - Presently occurring. Slow to moderate rate if existing pressures are removed. Sediment, seed or large wood input - Little sediment, seed or large instream wood (if required) input. Excess sediment supply - Moderate sediment slugs
Low Priority
Geomorphic condition - Poor Rate of recovery or presently occurring - Very slow. No or very little recovery occurring. Often degradation still occurring. Has recently changed or is on the verge of changing to a different style category. Sediment, seed or large wood input - No sediment, seed, or large instream wood (if required) input. Excess sediment supply - Large and continuous. |
