4.5 Project Monitoring and Performance Criteria

The success of the Vegetation Rehabilitation Plan will be determined by
compliance with performance criteria defined below.

Under the principles of due-diligence for self-assessable development; we consider
it prudent to undertake project monitoring based on assessment of performance
criteria at regular intervals. Performance: Criteria are based on recognised
vegetation rehabilitation principles, and on mimicking structural and floristic
parameters of similar naturat vegetation communities in the area.

The maintenance period will commence after all declared and environmental
weeds have been removed and all replanting and rehabilitation works have been
finalised. The monitoring of rehabilitation progress will be undertaken at regular
intervals (12 and 24 month basis) commencing from the initiation of the
maintenance period. Required variables for the monitoring program are to reflect
the objectives described for Performance Criteria including:

e Level of declared and environmental weed recovery;
e Density and diversity of planted species (level of senescence); and
« Growth rate of planted species (Height and Foliage Cover).

Detailed Performance Criteria milestones are to be assessed periodically by a
suitably qualified consultant. Where performance criteria are assessed as
insufficient, corrective actions (refer to Section 4.4 - Maintenance
Schedule/Requirements for details) are to be undertaken. Performance Criteria
milestones are as follows:

a) Upon Completion of initial plantings
b) “On Maintenance’ inspection.

e® The maintenance period has been in progress for no less than 1
year;

Control of environmental and declared weeds;

e Cleared and degraded areas have been planted with appropriate
native species at densities comparable to those at “As Planted”
levels and/or levels in similar natural vegetation communities
(>90% survival of seedlings); .

e¢ Revegetation is well established with planted tree species at
heights of no less than 1m and with supplementary planting to be
undertaken to replace losses;

¢ Species diversity levels are comparable with “As Planted” levels
and/or levels in similar/surrounding natural vegetation
communities.

c) “Off Maintenance” inspection

e The maintenance period has been in progress for no less than 2
years;

e Rehabilitation resembles a naturally structured ecosystem — plant
height and foliage cover are generally comparable to similar
vegetation communities of similar age in the area (no less than
80% of naturally occurring foliage cover and height). Species
