A Visual Record of the Nests

The graphic in this blog shows the nests that we have confirmed are actual sea turtle nests that have been laid and officially recorded (red pins), or have officially hatched according to our observations. The remaining "probable" nests (see previous blog) shown on a previous chart are ones that we suspect have been laid. Remember, our recent relevation by EAI, Inc. that they are only recording one out of every 24 sea turtle nests that are laid in a large section of the beach that we cover, has dramatically changed the "accuracy" of our recorded nests this year, since we didn't start keeping our own records until early July. Our technique for the remainder of the summer is to watch for nests that hatch, then record that date, and work backwards (subtract last year's average number of days of incubation for the nests) and use our best "guestimate" of when then nests were laid. It's not the most accurate, scientific method, but it's all we have to work with this year!
