The water in the nature reserve in Texel, the Netherlands turns pink. That also happened five years ago. The cause could be a severe drought on the island of Wadden. This means that the water is high in salt and low in oxygen.

A notable natural phenomenon on the island of Wadden in the Netherlands on Texel: The waters of the lake in the Wagejot Nature Reserve, not far from the village of Oosterend, slowly turn pink. And that’s not the first time, in 2017 the lake was already flamingo pink.

Still, it was a shock to Forester Eckhard Boot of the Dutch Natural Association Natuurmonumenten. “You think this will happen only once. It’s unlikely that it will happen again,” he tells the Dutch public broadcaster NOS. “So when we were looking at the top of the embankment yesterday, we thought: it couldn’t be true? But it was.”

Five years ago, researchers at the Royal Netherlands Institute for Sea Research found an explanation for the drought. As a result, the salt content in the water was very high and it contained almost no oxygen.

Later, researchers discovered two underwater organisms that caused the pink color.One of these is algae Dunaliella salina, Microalgae that can breed under salty conditions. In large quantities, they can turn the lake into a bright pink. again, Oxyrrhis Marina Found in the water. This pink creature is associated with the brilliance of the ocean, a plankton that can illuminate the ocean.

According to ecomale biologist Arthur Oosterbaan, the large-scale growth of both organisms was facilitated by a combination of heat, high salt from drought, low oxygen content, and fertilizer from bird droppings.

Forest Ranger boots expect the cause to be the same again. He emphasizes that it is a natural phenomenon without chemical causes. “Are you in the way? No, I don’t think it’s so negative that it’s happening. The only thing is that it may happen more often as it gets warmer and dries. “
