Attachment D - Riparian

3.            Results
The constructed greenhouse does not intersect any mapped riparian buffer areas. However, a rock
sediment basin (see Figure 1) has been constructed to the north of the greenhouse within the mapped
riparian buffer area. Furthermore, a drainage channel (see Figure 2) has been constructed along the south-
east section of the greenhouse, extending into the riparian buffer area. The watercourse in this section of
the lot is a third order tributary of Six Mile Creek. Presently, the watercourse supports a gallery rainforest
vegetation community analogous to Regional Ecosystem 12.3.1. However, the vegetation associated with
this watercourse is not mapped as remnant vegetation as defined under the Queensland Vegetation
Management Act 1999. A number of camphor laurel (Cinnamomum camphora) were recorded within the
riparian vegetation.

The waterway is an unnamed third order tributary of Six Mile Creek. A 50 m riparian buffer area has been
mapped under the Noosa Plan Biodiversity Overlay Map. The total area of disturbance within the riparian
buffer area is approximately 2400 m² with the majority of this being associated with the constructed rock
sediment basin (approximately 2160 m²). The rock sediment basin includes a drain into the nearby
waterway. An earthen bund wall (Figure 3) has been installed between the south-eastern to southern part
of the greenhouse, the associated sheds and riparian vegetation of a waterway which feeds into the third
order stream. This bund does not occur within the riparian buffer area.

The riparian buffer area on the lot consisted of a mix of former turf cultivation and areas of largely weeds.
The area appears well maintained (see Figure 4). The buffer area also includes riparian vegetation
associated with the watercourse.
