Discussion 40 Limitations of the data 40 Large-scale sites 40 How long did it take for the large-scale sites to stabilise? 40
What were the primary causes of reduced success( soil stability) at the sites and how can these be remedied? 41
What changes to planning and design are recommended to improve large-scale gully remediation? 42
Focus on revegetation 42 Site specific grazing plans 44 Continue to address maintenance requirements early 44 Consider low impact remediation works 44
What monitoring and maintenance schedules and maintenance costs could be embedded in large-scale gully remediation plans? 45
Small-scale sites 46
How long did it take for the small-scale sites to stabilise? 46 Catchment only works 46 Gully remediation works 46
What were the primary causes of reduced success( soil stability) at the sites and how can these be remedied? 46
What changes to planning, design and implementation are recommended to improve small-scale gully remediation? 47
Plan for tropical deluges, limited infiltration and high runoff 47 Adhere to the plan 47 Understand the soil and plan accordingly 47 Plan banks that slow, rather than retain water 49 Rock chutes in gullies- commit to high maintenance or avoid 50 Vegetate rock chute abutments 50 Limit grazing at sites that have little topsoil 50 Use low impact remediation techniques for better cost effectiveness and low risk 51
What monitoring and maintenance schedules and maintenance costs could be embedded in small-scale gully remediation plans? 52
