2.2. Survey Methodology

      Animal Signs
      Native wildlife leaves scats, tracks and scratches that can be identified and are described by
      Barbara Triggs (2004). These indicators should be used to provide positive identification of
      species to be found within the area marked for disturbance. This data should be recorded in the
      survey report.


      Playback Calls
      Playback calls can be used in an area to identify active species via acoustic monitoring these
      methods can be used to identify the presence of inconspicuous species. When conducting
      playback surveys use a megaphone (Figure 4- play the call of the target species for two minutes.
      Allow a five-minute listening period between each playback using an Acoustic recorder (Figure
      4- repeat this methodology three time per target species. Call-back session will be limited to one
      session per day to limit the disturbance it causes to targeted species.

      Diurnal Bird Survey
      This non-intrusive active area search provides a census of the avian biodiversity and abundance
      within the survey site. This survey technique requires a highly skilled observe with substantial
      experience in local bird species and bird calls. Transect are slowly walked through the site just
      after dawn when birds are the most active. Avoid disturbing nesting birds during the survey.


      Spotlight Counts
      Native wildlife may be detected using a method of spotlighting during nocturnal surveys.
      Spotlighting surveys are most effective way to determine arboreal mammal abundance and
      density (Braithwaite et al. 1988). Can also be used to spot large terrestrial nocturnal mammals,
