Knowra Dark-sky preserve Dark-sky preserve A protected area managed to limit artificial light and preserve dark night skies. It supports astronomical observation and reduces disruption to nocturnal environments.
Light pollution : Unwanted or excessive artificial light that brightens the night sky and affects people and ecosystems. Preserves restrict the emissions that cause skyglow and ecological disruption.
Astronomical observatory : A facility equipped to observe celestial objects using instruments such as telescopes. Dark-sky preserves can protect conditions needed for nearby observing facilities.
Natural Bridges National Monument : A national monument in Utah known for natural stone bridges and protected dark night skies. It became the first International Dark Sky Park in 2007.
Artificial light at night : Human-produced illumination present during nighttime hours. Preserve policies address its effects beyond astronomy, including ecological and human health concerns.
Skyglow : Diffuse brightening of the night sky caused when artificial light scatters in the atmosphere. It is the visible result dark-sky management aims to reduce.
Astrotourism : Travel motivated by observing stars, planets, eclipses, or other night-sky phenomena. Dark skies can attract visitors and support local economies.
Aoraki Mackenzie International Dark Sky Reserve : A protected dark-sky area in New Zealand’s Mackenzie Basin that includes Aoraki Mount Cook National Park. Its regional lighting controls demonstrate protection across parks and settlements.
Ecological light pollution : Artificial light that alters the behavior, physiology, or interactions of organisms and ecosystems. It frames darkness as habitat protection rather than only an astronomical resource.
Outdoor lighting : Artificial illumination used outside buildings, roads, and other structures. Shielding, direction, intensity, and timing determine its effects beyond the site.
Nocturnal animal : An animal that is primarily active during the night. Preserve lighting limits can reduce disturbance to night-active species.
