The predicted collision rates resulting from CRM analysis did not indicate any species for which population-level impacts are likely. No tier 1 target bird species are predicted to experience collisions more frequently than one fatality per 2 years under the realistic collision avoidance rate scenarios modelled. Five tier 1 target bird species are predicted to experience at least one collision in 10 years (Pygmy Cormorant, Cinereous Vulture, Steppe Eagle, White-tailed Eagle, and Lesser Kestrel) and three additional tier 1 target species are predicted to experience at least one collision in 20 years (Great White Pelican, Egyptian Vulture, and Golden Eagle). Egyptian Vulture and Steppe Eagle are of Critical and PBF status respectively. Among tier 2 target bird species, only the Eurasian Kestrel, a widespread and abundant species that does not have elevated conservation status at the national or international levels, was predicted to experience more than one collision per year under the most likely collision avoidance scenarios modelled (16.2 collisions per year). For non-target bird species, the CRM analysis predicts collision rates as high as 1.05 collisions per year for Mallard under the most realistic CA parameter values, and collision rates more frequent than once per 5 years for five additional species of water bird (Gray Heron – 0.907 collisions per year, Gadwall – 0.597 collisions per year, Green-winged Teal – 0.585 collisions per. Dzhankeldy 500MW Wind Farm ESIA Volume 2- Main Text, Tables & Figures 262 year, Caspian Gull – 0.684 collisions per year, and Black-headed Gull – 0.271 collisions per year). For all other species, collision rates are predicted to be once every 6 years or rarer under the most realistic CA values. At this level of predicted collision risk, the WF does not raise significant concerns for potential impacts to any of these species. The magnitude and unmitigated significance calculations are presented in the table below.

Post-construction biodiversity management program will include a Fatality Monitoring Plan; detailed and intensive carcass searches will take place throughout the wind farm. Best international practice will be followed in determining the appropriate level of search efforts as well as formulas for searcher- bias adjustments; Thresholds will be established for acceptable levels of annual losses, which will be determined on a species-specific basis via the principles of Potential Biological Removal. Should the Fatality Monitoring prove that thresholds for any particular species are reached, this will trigger an upscaling of mitigation. These thresholds will be developed in the Collision Risk Management Plan. The Collision Risk Management Plan will include all operational measures that can be implemented to reduce collision risk. This plan will include a detailed Shut-down Dzhankeldy 500MW Wind Farm ESIA Volume 2- Main Text, Tables & Figures 264 on Demand (SDOD) Program, wherein turbines are shut-down and prevented from moving, allowing birds to pass through the area safely. SDOD can be detection- led (via observer, automated imaging, thermal or radar systems) or conditional upon seasonal and meteorological conditions. Furthermore, shut down triggers can be manual )via operator) or automatic (via the SCADIS). The exact mechanism for proposed SDOD is being deliberated and developed by the project proponent in discussions with financial lenders and lenders technical advisors. It is considered that as per the low predicted collision rates, SDOD will not be needed for the project. However, SDOD will be implemented for high-risk areas if ongoing fatality monitoring prove that accepted loss thresholds are being exceeded. . For tier 1 species, a threshold of zero fatalities will be established. In the event of a tier 1 species fatality, adaptive management will be triggered and the SDOD Program will come into effect. The mechanism for this adaptive SDOD will be outlined in the Collision Risk Management Plan. 1>1>1>1>1>1>1>1>1>1>1>1>1> Download 6.64 Mb. Do'stlaringiz bilan baham: |
