You arrive thinking it will be empty, but it never is.
The salt holds more life than most forests.
By the time I reached the gates at Fuente de Piedra, the sun had already dropped behind the low limestone ridge. The light left everything the colour of burnt copper. The air smelled of algae and dust. I’d come to help record migratory counts — flamingos, stilts, sandpipers, the quiet small ones that feed until the moon takes over.
The rangers work in pairs here. One carries binoculars, the other the old clipboard with a rubber band to stop the pages flying off. They have to keep counts under ten-minute intervals before the light vanishes. You can hear the clicks of the mechanical counters if you listen hard enough. It’s the sound of someone trying to catch movement before it disappears.
I’d done this kind of work years ago in Guinea, counting chimpanzee nests at dawn. Different continent, same rhythm: arrive early, wait, write, accept that half the time your data looks like a child’s notes. Out here the trick is learning what the water is saying.
The salt flats are thin ecosystems. They live between flood and drought, the old saltpans cut with hand-made channels. If you stand long enough you’ll notice how the air changes with each pool. Some are hypersaline — thick enough that no insect hovers. Others, freshened by rain, hum with midges. These micro-differences decide who lives here and who passes through.
A pair of greater flamingos dropped in just before dark. They landed awkwardly, like parachutists, then settled into the shallows. Their reflections trembled on the surface for a few seconds, then vanished in the ripple.
I checked the salinity reading. Thirty-six parts per thousand. Slightly lower than last month, probably because of the October rain. That tiny change will shift the balance of brine shrimp, which in turn shifts the pink of the flamingos’ feathers. Biology is never static, even in a place that looks frozen.
One of the rangers, Mateo, told me they used to harvest salt here until the early 1990s. He pointed to the low mounds along the southern edge. “El trabajo era duro,” he said. Hard work, endless light. Now the site is protected under the Ramsar Convention, though the boundary lines still cut across private fields. Conservation here isn’t a postcard; it’s a negotiation between water, ownership, and memory.
When we finished, the last light went grey and the wind came off the lagoon. The flamingos kept feeding, heads down, silent. I packed the salinometer, zipped the case, and felt the salt drying on my hands. It leaves a thin film that stays until morning.
People think rewilding is about adding life, but most of it is about listening. These flats already know what to do if we stop interrupting. You just have to stand still long enough to hear it.
