Attunga Heights Rehabilitation Specification 20

7.5 PERFORMANCE STANDARDS

7.5.1 Contractor

All declared and environmental weeds will be absent from all areas prior to commencement of
use. It is anticipated that scattered minor herbaceous weeds are still likely to be present in some
locations and occasional seedlings of environmental weeds. The 12 month maintenance period
should focus on identifying the areas where weeds are still present.

Planting will be checked for senescing individuals. Replacement planting will be undertaken on
a regular basis in response to regular monitoring. Mulch is to replaced around planted rainforest
species where canopy closure is absent.

7.5.2 Ecology

The success of the rehabilitation will be determined by ascertaining the progress of vegetation
toward the target vegetation communities as defined in Section 5.0. Within the project timeframe
it will not be possible to re-establish the pre-European mature vegetation, but the pattern of
distribution of the forest communities and many of the constituent species will be present and this
will allow progress toward the target condition to be demonstrated.

The Restoration Ecologist will determine the success of the rehabilitation work by assessing the

effectiveness of weed control, the recruitment of new native individuals and the active growth of
planted specimens.

8.0 MONITORING

 

This will be undertaken once a month for the initial stages and for the 12 month period following
on maintenance. The following will be monitored by the Restoration Ecologist:

e Presence of environmental weeds;

e¢ Number and survival of plants planted;

e Monitor active growth of planted specimens;

e Whether native species are being recruited (Note: absence of recruitment will not be used
to determine project success); and

© Whether rainforest species in areas of no canopy are mulched.
