Global Short Term Trend: Decline of 30-70%
Comments: The Marine Turtle Specialist Group of the World Conservation Union analyzed population trends at 32 index nesting sites around the world and found a 48-65% decline in the number of mature females nesting annually over the past 100-150 years (this represents 3 generations).
In a couple dozen areas for which recent data are available, most populations were stable or increasing (19 or 23) (NMFS and USFWS 2007). These trends should be interpreted with caution because events that affected juvenile recruitment up to several decades ago may continue to affect nesting populations.
Global Long Term Trend: Decline of 30-70%
Comments: Number of subpopulations and especially population size undoubtedly have undergone a major decline over the long term.
