                                                    watercourses by a distance not less than the distances
                                                    identified below, measured from high water mark or the
                                                    top of the bank, whichever is the greater distance—

                                                    S5.6 Where Forestry is carried out on that part of premises
                                                    indicated as Riparian Buffer Area and outside the
                                                    separation distances specified in S5.5—
                                                    a) species planted are of local origin and are harvested
                                                    through sustainable harvesting;
                                                    and
                                                    b) any undesirable plant species are replaced by vegetation
                                                    of local origin.



The construction of the rock sediment basin and drainage channel has impacted on the minimum amount
of area required for this infrastructure. As can been seen in Table 1, construction of the drainage channel
and rock sediment basin does not meet any of the probable solutions. However, an alternate solution to
the disturbance could be proposed. The residual impact associated with construction of the rock sediment
basin and drainage channel on the riparian buffer can be offset. The alternate solution could include all or
part of the following:

         Removal and control of camphor laurel along the portion of the waterway that occurs on the lot.
          Any weed control would need to consider the type and application of herbicide that could be used
          in proximity the waterway and surrounding native vegetation.
         Removal and control of other environmental weeds in proximity to the riparian vegetation and
          within the riparian buffer area.
         Undertake revegetation programs within the riparian buffer area by planting of species that would
          have originally occurred in this area as determined by the pre-clear Regional Ecosystems mapped
          over the lot.
         Undertake regular water quality monitoring in the waterway

By actively managing the riparian buffer area and the riparian vegetation of the lot through a combination
of weed control and revegetation programs, the disturbance associated with the construction of the
drainage channel and rock sediment basin should be adequately offset. This may require the preparation of
a riparian vegetation management plan highlighting objectives, key tasks and approaches to adequately
manage the riparian buffer area and riparian vegetation to a standard accepted by the Noosa Shire Council.
