Rehabilitation & Landscape
Management Plan
Objective
Long-term Completion Criteria
(i.e. Life of Mine)
Medium-term Success Indicators
(i.e. < 5 years)
Short-term Monitoring
(i.e. Annually)^
• Minimum of 70% vegetative cover
over 80% of rehabilitated areas *
• Suitable pasture species dominant
• Minimal presence of weeds (esp.
Galenia sp)
• Weed control and ameliorative
measures as necessary
• Tree plots recruitment rates are
equal to or exceed mortality rates
• Grazing conducted in accordance
with land classes
• Tree plots indicating good growth
and mortality rates – nearing
completion criteria
• Successful small trials of grazing
• Monitoring of vegetation and
erosion and sediment control as
discussed in Section 3.2.5
Surface run-off is not
polluting waters
off site
• Water leaving site must meet EPL
6538 criteria of pH between 6.5
and 9.5 and TSS of < 120 mg/L
• Water monitoring results within
limits of EPL 6538 and all dirty water
retained on site
• Monitoring and inspection of
water management structures by
appropriately qualified person
FINAL VOID
• Design to stable gradient by
geotechnical personnel, if
necessary blast
• Final high wall meets design
requirements, geotechnical stable
• Monitoring confirms stability
• Monitoring of high wall stability
All hazards associated
with the final high
wall and low wall are
controlled
• Fencing established along the
entire length of the final high wall,
preventing pedestrian and live
stock access
• Berms, trenches and catch
benches established at
appropriate intervals where
necessary
• Implementation and ongoing
maintenance of fencing
• Exclusion of access
• Implementation of berms and
trenches at regular intervals
• Stability of berms and trenches
• Regular monitoring of fence
condition and restriction of
access
• Regular monitoring and/or
maintenance of berms and
trenches
