Turtles, both terrestrial and marine, face significant threats to their long-term survival. Their life history, characterized by late reproductive maturity and a reliance on high adult survival rates, makes them vulnerable to human-caused mortality. Protecting these reptiles requires a multi-faceted approach, starting with informed choices made by individuals. Understanding specific actions that mitigate immediate dangers is paramount to effective conservation.
Protecting Turtles in Local Environments
Encounters with freshwater and land-dwelling turtles often occur near roads or in residential areas, requiring immediate and careful intervention. During nesting season, typically late spring and early summer, female turtles often cross roads in search of suitable nesting sites, leading to high road mortality. If you encounter a turtle crossing a road, safely pull over and assist it by moving it in the direction it was already headed, as relocating it to a different area will only cause it to try crossing the road again.
For large, defensive species like snapping turtles, avoid picking them up by the tail, which can cause serious spinal injury. Instead, use the “wheelbarrow” method, which involves lifting the rear of the shell to encourage the turtle to walk forward, or gently prod it with a blunt object. Female turtles seek out soft, exposed soil or gravel for laying eggs. If you find a potential nest, marked by disturbed earth or tracks, leave it alone and protect it from disturbance to maximize successful incubation.
If you discover an injured turtle, contact a local wildlife rehabilitation center or conservation authority for specialized medical care. Place the animal in a quiet, dark box and keep it warm. Aquatic turtles do not need to be submerged in water during transport, and injured turtles should never be fed. Attempting to treat wounds or relocate a turtle undermines the expertise of trained professionals and the animal’s connection to its home range.
Reducing Marine and Coastal Threats
Coastal residents and visitors can significantly reduce the threats facing sea turtles by mitigating the effects of light pollution and marine debris. Hatchling sea turtles rely on the natural light horizon over the ocean to navigate from their nest to the water, but artificial light sources disorient them, causing them to crawl inland and perish from exhaustion or predation. To counteract this, coastal property owners should adhere to the “Keep it Low, Keep it Shielded, Keep it Long” principle for outdoor lighting.
This approach requires using fixtures that are low to the ground and fully shielded to direct light downward. Property owners should replace bright white or blue bulbs with long-wavelength lights, such as amber or red LEDs, which are least attractive to sea turtles. Inland activities also contribute substantially to marine pollution, as an estimated 80% of ocean plastic originates from land-based sources. Sea turtles frequently mistake floating single-use plastic bags for jellyfish.
Their downward-facing throat spines prevent them from regurgitating ingested debris, leading to fatal intestinal blockages or starvation. Reducing the use of single-use plastics and participating in local cleanups are direct ways to remove life-threatening debris. Even plastic that breaks down into microplastics can be ingested by turtles through the food chain, impacting them at every life stage. Ensuring all waste is properly managed and contained interrupts the flow of plastic pollution into marine habitats.
Responsible Consumer and Citizen Choices
Consumer behavior has a widespread, indirect influence on turtle populations globally, particularly through the exotic pet trade. The illegal collection and trafficking of native turtles, often destined for the international pet trade, severely impacts wild populations. Because turtles have delayed reproductive maturity, the removal of even a small number of reproductive adult females can cause a rapid and irreversible population decline. The best way to combat this illicit trade is to never purchase a wild-caught turtle and report suspicious sales to wildlife authorities.
Recreational boaters also play a role in protecting turtles by minimizing the risk of vessel strikes and habitat damage. When operating a boat in shallow coastal waters near sea turtle habitats, reduce speed to a safe minimum, around 5 to 10 knots. Boaters should also designate a spotter to look for turtles surfacing to breathe. Following marked channels avoids prop scarring, which damages the delicate seagrass beds that provide forage for many sea turtle species.
Improperly discarded fishing gear, especially clear monofilament line, is a significant threat. It is nearly invisible in the water and causes severe entanglement and ingestion injuries. Anglers should commit to using monofilament recycling bins found at marinas and fishing access points. They should also consider using barbless circle hooks, which reduce the risk of internal injury if a turtle accidentally ingests the bait.
