To assess the response of flatback hatchlings to common industrial light types a different intensities and elevation
Type of Study:
At medium and high light intensities of all 3 light types (metal halide, fluorescent and high pressure sodium vapour) and at low intensity metal halide, hatchlings were more attracted to light at 2° elevation compared to 16° elevation. At low intensity there was no significant difference in orientation of hatchlings exposed to high pressure sodium or fluorescent light glow at either elevation.
Maintain high inland elevations to improve hachling sea finding.
