We all have lights outside at night. It makes you feel safe and allows you to see what is going on after dark in our area. However, artificial light is a threat to wildlife. Light at night disrupts natural behavior and can cause injury or death to the animal population. This can be prevented or even improved by installing the proper lighting for nighttime use.
Installing the lights as low as possible with a shield to prevent light from shining out and up is the first step to ensure the lights are wildlife friendly. The light required at night is primarily on the ground and should be shielded to provide the light where it is needed. The shield and height of installation will ensure light does not cast up into the sky our outwards from the needed area.
If large area lighting is needed, such as flood lighting, putting them on motion sensors on short increments would provide the lighting when it is needed and kept off all other times. That way, the light is on when you need it, but will then turn off once there is no longer movement and it is not needed. Since the light won’t stay on for hours at a time, it will cause little disturbance to the surrounding wildlife.
Finally, using long wavelength lights such as amber and red lamps provides enough lighting for us as humans to see; however, is not the right wavelength for most animals to notice. These types of lamps will not disturb nocturnal animals. It will also not have them gravitate towards an area they are not wanted, especially if you live near a coast or wildlife area.Putting this all together doesn’t just benefit the animal population at night. It also provides cost benefits as the lights will not be shining unnecessarily and therefore uses less power resulting in a lower power bill.
