Recovery of green turtles on Aldabra [PDF]

open access: yesOryx, 1985
The numbers of green turtles that nest on Aldabra's beaches have increased significantly in the past 20 years. The author, who studied the turtles between 1981 and 1984, suggests explanations for the recovery. It is likely that the Aldabra population is still well below that which thrived there before exploitation began, and with sustained conservation
