      ii) The Plot Survey Method involves the establishment of contiguous plots measuring
          50m x 10m as described by Neldner et al. 2012 and the Guidelines. Within each
          plot the following information is recorded and described:
           ▪ GPS location of plot.
           ▪ Number of individuals and observations on age structure, health etc.
           ▪ Description of vegetation structure including RE type.
           ▪ The identities of all threatened or near threatened plant species found within
                the vegetation community.
           ▪ Landscape attributes including landform, soil type, geology, slope, aspect, and
                altitude; and
           ▪ Specific habitat features including level of disturbance etc.

3.2.2 Ecological condition assessment

The ecological condition of the vegetation was evaluated using a modified Keighery
Condition Scale (Keighery, 1994), as shown below in Appendix D, which assesses the
components of vegetation community structure, composition and regenerative capacity with
regard to disturbance due to land use.

3.2.3 Koala Habitat Trees assessment

Koala Habitat Trees (KHT) were surveyed within the impact area. According to the
Queensland Environmental Offsets Policy Regulation (DES, 2022), a “koala habitat tree”
means a tree of either the Angophora, Corymbia, Eucalyptus, Lophostemon or Melaleuca
genus.

A “non-juvenile habitat tree” means a koala habitat tree whose:
    a. Height > 4m; or
    b. Trunk > 31.5cm at 1.3m above the ground.

3.3      Field assessment method - Fauna

3.3.1 Fauna survey method

A diurnal and crepuscular fauna assessment was conducted on the 5th March 2025 to
identify the presence of conservation-significant fish, invertebrates, birds, reptiles,
amphibians and mammals (including microbats and arboreal species).

A targeted crepuscular and nocturnal search for threatened listed amphibian species was
conducted on the 5th March 2025 on a damp night with warm temperatures and recent rain
providing suitable conditions for the amphibian survey.

The fauna surveys were undertaken in accordance with the Nature Conservation Act 1992
and Nature Conservation (Animals) Regulation 2020 using the methods described below.

Active search
This technique involved investigation of habitat features and searching for fauna under logs,
rocks, leaf litter and decorticating bark for cryptic fauna, particularly reptiles.
To detect arboreal fauna in the mid-storey and canopy layers including microbats, birds and
habitat features such as nests and dreys, Avalon 10x40 HD binoculars were used.
