Abstract

An aerial survey of the shorelines of the Mexican Pacific states of Michoacan, Guerrero and Oaxaca revealed that nesting by the leatherback turtle, Dermochelys coriacea, occurs in a greater density and over a much greater extent than previously documented. Leatherbacks in this area are referable to a single breeding population which is by far the largest known. A preliminary estimate of the size of this population combined with available information on other populations gives a new world population estimate of 115,000 mature females. Because of severe stresses on all major populations of the species, "endangered" status is still considered justified.
