Conservation Efforts: Coastal Development

overdeveloped coastlineAs humans continue to develop and live in and around coastal areas it is becoming harder for turtles to find safe, unused sandy beaches. There are many ways coastal development can hinder the sea turtle life cycle.

2) Beach umbrellas penetrate the sand, breaking eggs in their nests, causing them to rot and affect the other eggs in the nest.
3) Lounge chairs and other recreational equipment left on the beach at night can block access to nesting sites for females.

Coastal armoring, which includes installing barricades (such as sea walls, rock revetments, jetties and sandbags) in attempt to protect beachfront property from erosion and wave action, negatively impacts sea turtle habitats.

These structures often block female turtles from reaching their prime nesting habitats.

This means that the sea turtles’ foraging habitats could be impacted as well.

A related concern is that coastal development and armoring will push turtles to marginal habitats, creating even lower nesting success.
