Management Action:

1.

2.

 

 

Performance criteria:

   

At the completion of the rehabilitation works, an on-maintenance period of 12 months will commence. Maintenance
of the rehabilitation areas will continue until the end of the on-maintenance period;

Control of weed species will be undertaken within each rehabilitation zone on a monthly basis for 6 months tollowing
the completion of revegetation works, then quarterly until canopy cover suppresses weed germination and growth.
Regular inspections and monitoring jeed-back will inform weed removal during the 12 month maintenance phase.
Mechanical weed control will be used as the preferred option where possible;

Where mortalilies of planted stock occur, they will be replaced with similar species consistent wilh the planting
prescriptions within two (2) months (or at suitable planting periods);

Growing stock will be watered at planting and on a needs basis depending on weather conditions during the
establishment phase. itis anticipated that plants will require watering on a weekly basis during the first eight weeks
and then on an as needs basis for the next six months during the establishment period. Rainfall periods may reduce
these watering requirements;

Detailed maintenance schedule is provided in Appendix B;

Regular monitoring over a 12 month period will be required at the completion of the rehabilitation works. Monltoring |
should be undertaken by a suilably qualified person (i.e. restoration ecologist). As a minimum the following will be
monitored:

= Weed control— extent and adequacy as well as any secondary weed responses to treatments;
= Presence of specific environmental weeds;

= Indicators of growth and survival of all plantings;

= Adequacy of site preparation, mulching, tree (and plant) protection and maintenance; and

= Adequacy of flow of information from ecological and project monitoring back to the contractor, and subsequent
response and integration of any modifications.

Monitoring should be undertaken at the completion of the revegetation works, then every three months for 12 months
post rehabilitation. The monitoring schedule may be required to be adapied if changes fo rehabilitation ,
works/pragress occurs; and

Brief report should accompany each monitoring period and should summarise the findings of monitoring events and |
identify the performance of rehabilitation works wilh reference to the objectives of this plan and performance criterla |
listed below. Where the objectives / criteria are not being achieved, ihe report should recommend relevant actions |
required to amend this situation. |

=  Mulched cover maintained around planted species;

«All mortalities replaced;

= Wo to minimal weeds;

= All vegetation strata's (i.e. ground layer, shrub, understorey tree & canopy) present; and

» All planted species showing evidence of heallh and vigour {i.e. new growth) and appear well established.

After the completion of 1 year of maintenance the jollowing should be achieved:
