Atol das Rocas

A protected biological reserve, Atol das Rocas is an atoll, or reef-island encircling a lagoon, which provides a home to various rare speicies of plant and animal life.  There is no human population, and in fact, people are not allowed on the atoll unless they have permission to conduct scientific research there, such as the volunteers of the Tamar project who tag and track turtles in this vicinity.
