Jensen Beach is known in the marine biology community for being a location for sea turtles to nest.

These notifications are meant to discourage tourists and residents from visiting the beach in the evening hours during these time periods.

Efforts are made to protect both species of sea turtles since nests have been declining in recent years due to the severe erosion of the beach.
