The impacts of artificial light on wildlife can take various forms. For instance, hatchling turtles may become disoriented towards light sources instead of the ocean, while migratory birds may alter their flight paths to avoid light, consuming more energy and diminishing their chances of reaching their destination.
Visible light sources and sky glow can affect wildlife behaviour differently, varying from species to species. For example, turtles may be deterred from nesting on illuminated beaches, and sky glow may disorientate hatchlings attempting to reach the water. Similarly, migratory seabirds may steer clear of areas with sky glow, extending their flight paths and reducing their likelihood of reaching their intended destination.
Artificial Light at Night Surveys and Light Audits
At WAVES, our methodologies for Artificial Light at Night Surveys and Light Audits are tailored to the species of concern, drawing on years of measurement and research experience. By understanding vision and light principles and applying best practice measurement techniques, we can assess the impact of light and offer design recommendations.
We collaborate with ecologists to identify species susceptible to light impact in a given area. Through precise measurements of light colour, intensity, and sky glow, we evaluate the potential impact on identified species and provide tailored lighting design guidance for the area, addressing both new and existing installations. Our services extend to assessing light levels against current Planning Scheme requirements or designing testing and monitoring methodologies as needed.
Light Management Plans
Moreover, we have extensive experience working on projects involving sea turtle-sensitive areas. Our Artificial Light at Night (ALAN) Surveys and Light Audits track changes in sky brightness over time and across locations, pinpointing problematic light sources. The insights from our investigations inform scientifically grounded guidance for rectification work and lighting design, offering solutions that can be seamlessly integrated into Planning Schemes.

Assessment and quantification of sky brightness are useful for monitoring the stability in sky brightness over time and may allow the impact of developments to be assessed.
