Potential associated impacts

Suggested indicators

Destabilised streambanks

• Hillslope erosion*
• Gully erosion*

Reduced trapping of eroded sediment and attached pollutants such as pesticides and nutrients, carried by runoff before it reaches the waterway

• Fine sediment in water*
• Nitrates in water*
• Phosphates in water*
• Faecal coliforms in water*

Invasion of exotic pest fauna and aquatic and terrestrial weeds

• Weed species*
• Weed cover*
• Exotic pest fauna*

Reduced shade over the waterway and subsequently reduced water temperature regulation.  Where reduced shade means the water temperature is warmer dissolved oxygen levels are reduced and algal blooms are more likely

• Dissolved oxygen*
• Temperature of water*
• Microalgae in water*

Reduced riparian vegetation condition

• Native plant richness*
• Weed species*
• Weed cover*
• Tree canopy cover & health*
• Shrub cover*
• Large trees*
• Organic litter*
• Fallen woody material*

Reduced habitat for native fauna

• In-stream habitat*
• Fish*
• Aquatic macro-invertebrates*
• River & wetland fauna*
• Native land fauna*

Reduced wildlife corridors to enable movement of native wildlife and plants between remnant habitats
