BL&A has developed a bird collision risk modelling package for wind farms that assists proponents and decision-makers to:
Understand geographical differences in the use of wind farm sites by species of concern, such as a threatened bird
Compare different wind farm layouts and turbine numbers to minimise collision risk
Present modelling results with appropriate statistical confidence limits.
These features of the BL&A bird collision risk model represent a significant improvement in the capacity to estimate collision rates in different parts of a wind farm, and to change wind farm layout and understand how collision rate responds to changes in layout and turbine numbers. This enables proponents to demonstrate how changes to wind farm layout and turbine numbers can reduce collision risk, a question often asked by government decision-makers.
Collision risk modelling of a wind farm requires a statistically rigorous spatial survey of the movements of a species of concern within and around a wind farm site. BL&A has developed best practice survey protocols that ensure data collected can be used for collision risk modelling.
We have undertaken collision risk modelling for wind farms on the following species:
