Management Actions:
1.   At the completion of the rehabilitation works, an oh-maintenance period of 12 months will commence. Maintenance
     of the rehabilitation areas will continue until the end of the on-maintenance period;
2.   Control of weed species will be undertaken within each rehabilitation zone on a monthly basis for 6 months following
     the completion of revegetalton works, then quarterly until canopy cover suppresses weed germination and growth.
     Regular inspections and monitoring feed-back will inform weed removal during the 12 month maintenance phase.
     Mechanical weed control will be used as the preferred option where possible;
3. Where mortalities of planted stock occur, they will be replaced with similar species consistent with the planting
   prescriptions within two (2) months (or at suitable planting periods);
4.   Growing stock will be watered at planting and on a needs basis depending on weather conditions during the
     establishment phase. It is 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;
S.   Detailed maintenance schedule Is provided In Appendix B;
6.   Regular monitoring over a 12 month period will be required at the completion of the rehabilitation works. Monitoring
     should be undertaken by a suitably 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.
7.   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 adapted if changes to rehabilitation
     works/progress occurs; and
8.   Brief report should accompany each monitoring period and should summarise the findings of monitoring events and
     identify the performance of rehabilitation works with reference to the objectives of this plan and performance criteria
     listed below. Where the objectives / criteria are not being achieved, the report should recommend relevant actions
     required to amend this situation.

Performance criteria:
•    After the completion of 1 year of maintenance the following should be achieved:
     •   Mulched cover maintained around planted species;
     •   All mortalities replaced;
     •   No to minimal weeds;
     •   All vegetation strata's (i.e. ground layer, shrub, understorey tree 6 canopy) present; and
     •   All planted species showing evidence of health and vigour (i.e. new growth) and appear well established.
