                                                                                             Native Foresters



The timing of the survey is considered suitable for detecting the target EVNT listed plant
species, none of which are deciduous i.e. Acacia attenuata, Acacia baueri, Eucalyptus
conglomerata and Allocasuarina emuina.

Survey timing in January, March and April is considered suitable for detecting target Wallum
frog species, with widespread ephemeral ponding and localised flooding in the weeks
and/or months leading up to the surveys.

Monthly rainfall totals were above average for March and April 2019, but well-below average
during January and February of 2019, and the total rainfall for November 2018 -April 2019
was less than half the average for this period (Table 3). Rainfall, surface and groundwater
conditions during field surveys would likely differ from those in years with average or above-
average rainfall. Variation in faunal assemblages and population dynamics (distribution,
density and breeding season) are also likely to occur as a result of changes in weather
patterns (e.g. late onset of the 2019 wet season associated with late breeding season).

2.2.6 Limitations of this study

Emphasis was placed on surveying listed threatened ecological communities, populations
and/or species that are considered likely to occur within the potential Impact Area and
likely to be affected by any ground or surface water alterations as a result of the creation
of Cells 2.3 and 2.4.

The timing of the survey was optimal for detection of Wallum frogs which were the target
species, expected to be impacted by changed groundwater hydrology. However, this is not
necessarily the ideal time to survey for all other species, unlikely to be impacted by
hydrological changes in the potential impact area.

The field assessment for non-target fauna employed passive techniques only (i.e. no live
trapping for mammals and reptiles). For a comprehensive assessment of species
presence/absence, particularly for cryptic or and nocturnal species such as small mammals
and fossorial reptiles, targeted species surveys in which a combination of Elliott traps,
Camera traps Herptile Funnel traps are required.
