E2M was contracted to assess bird and bat utilisation at the Kaban Wind Farm development to determine turbine collision risk of potentially occurring threatened and migratory bird and bat species. A risk profile for each turbine was established based on the results of the survey.
Changing disturbance footprint and turbine locations.
E2M utilised state-of-the-art GPS capture technology (Trimble TDC600) and bioacoustics recording devices (Anabat Swift Detector) to provide cost-effective data capture and analysis.
E2M staff were able to adapt to changes to turbine locations while in the field and rescheduled the survey timetable as needed. A comprehensive record of 58 bird species and their abundances across different periods of the day was achieved (six surveys per turbine/168 surveys total), and at least 12 species of Microchiroptera bats were identified in the survey area. Approximately 95% of birds were observed below turbine collision height; only one turbine was assessed to be high risk due to threatened species records.
