Save our biodiversity

Increasingly scientists are understanding the negative impact light has on pollination, nocturnal, migratory and reproductive behaviours in birds, mammals, insects and plants.


“The introduction of artificial light probably represents the most drastic change

human beings have made to their environment.”


For billions of years, life on Earth has relied upon predictable rhythm of day and night - circadian rhythm. It’s encoded in the DNA of all plants and animals. Humans have radically disrupted this cycle by lighting up the night environment.

To address the conservation challenge to threatened species migratory behaviours disrupted by artificial light,, the Federal governments Department of the Environment and Energy has developed the National Light Pollution Guidelines for Wildlife including Marine Turtles, Seabirds and Migratory Shorebirds. These Guidelines aim to raise awareness of the potential impacts of artificial light on wildlife and provide a framework for assessing and managing these impacts around susceptible listed wildlife.

Here are some effects of artificial lights in the natural environment:


Turning night into day. Nocturnal animals sleep during the day and are active at night. Inclusion of light at night changes these predatory behaviours.
