Florida’s Light Pollution Signature Florida’s Wildlife Ecosystems Affected by Light Pollution Conservation Corridor Daytona Beach Orlando Metro Area
The length of night at various times of year will determine an animal’s instinctual behavior from breeding and feeding to migration.
Light pollution can throw disrupt this internal timing and create confusion and disorientation in wildlife.

Light pollution is trespassing into wildlife habitat Wildlife Concerns From Exposure to Light Pollution Habitat Disturbance Wildlife Behavior Wildlife Survival Wildlife Issue
The darkness of night is a perfect time for many birds to migrate or hunt. These birds are often dependent on darkness to successfully complete migration or to find a meal. When artificial lights intrude on what should be a very dark area, birds can become disoriented. This can cause them to crash into structures or become focused on a distant light source. Artificial light can also disorient migratory birds, throwing them off course.

What are the effects of light pollution on their habitat and behavior?
Public Action Precedents in Wildlife Conservation Involving Light Pollution
SEATURTLES - first identified light pollution indicator organism. Led to nation’s first public outdoor lighting ordinance in Florida for wildlife conservation purposes.
BIRDS – FLAP (Fatal Light Awareness Program) Highly successful Canadian public program aimed at reducing birds kills from collusions with lighted city buildings. Program identifies numerous bird species at risk from light pollution. Visit www.flap.org
SW USA ENDANGERED CAT SPECIES - US Border Patrol proposes putting up bright lights along US-Mexico border inhabited by endangered cats. USFWS presses for Environmental Impact Statement (EIS).
Innovative Communities with Light Pollution Control That Benefit Wildlife and Public
Ocean Reef, Florida - private development in Key Largo, Florida with no street lights. Surrounding mangrove and waterway habitats enhanced.
Harmony, Florida - In 2009, was recognized by the International Dark Sky Association (IDA) as the world’s first Dark Sky Developments of Distinction. The award is given to communities whose planning actively promotes a more natural night sky. .
Palm Beach County and Sanibel Island, Florida - public outdoor lighting ordinances for coastal wildlife conservation and tourism. Beach and shore habitats enhanced.
