Inside the SAVE Field Guide: How We Protect Every Nest

Dentro de la Guía de Campo SAVE

Every SAVE volunteer starts with the same document: a field guide built entirely around one idea—consistency. The data we collect only matters if it’s gathered the same way, season after season, no matter who’s on the beach that night. And underneath every procedure is a simpler rule: turtles nest and hatch without human help all over the world, so our job is to interfere as little as possible while still protecting what we can.

Spotting a nesting mother (May–November)

Nesting mothers are easily startled. Bright lights or loud noises can send her back to the water before she lays a single egg—so once we spot one, the rule is simple: no noise, no white light, only red. If she leaves without nesting, she’ll usually come back later that same night or the next to try again. We watch from a distance and let her work.

The nesting process

A female turtle may spend an hour or more just choosing a spot before she starts digging. She excavates a wide area first, then finds the right spot to dig the actual egg chamber using her back flippers alone. Once she starts laying—usually 80 to 180 eggs per nest—she enters something close to a trance, and that’s the volunteers’ cue to approach. We always come from behind, moving low, almost crawling, red light only.

If we find a turtle

If she’s heading toward a bad spot—another nest, an obstacle—we can sometimes redirect her by acting like a wall: standing still, blocking the path, giving her nowhere to go but a better direction. Once she’s laying, we measure her shell and record: stick number, date, time, species, zone, tag, nest placement, and any injuries or notable observations.

Each nest gets a marking stick labeled C.M. for green (Chelonia mydas) or C.C. for loggerhead (Caretta caretta), planted one hand’s width above the actual nest. If the turtle’s shell shows barnacles or damage, we photograph it. All of it gets logged in the season data book by 11am the same day, or the next morning at the latest.
