Recently, a scientific study revealed that “A quarter of threatened freshwater fauna”, that is, at least 4,294 species of 23,496 freshwater animals on the IUCN Red List, are at high risk of extinction.

We are far from considering that biological pools are part of the solution to this problem, no way! But at least biological pools are not part of the problem, like conventional pools, where it is not uncommon for animals to die in the basin because they have no exits from the chlorinated water.

Biological pools are breeding grounds for amphibians and function as stepping-stone habitats. Especially in these winter days, owners of biological pools may notice this when they find newts and frogs in the water. These amphibians look for places with good quality water to ensure the new generation of these animals that live on land during the dry season of the year and seek out water in cool weather when almost no one thinks about taking a bath in the biological pool.

Portugal is home to a wide variety of amphibians, with a total of 17 species. Unfortunately, many of these species are facing threats and are listed on the IUCN Red List as Vulnerable, Endangered or Critically Endangered. There are 10 species on the IUCN Red List, more than half.

The main threats to these amphibians include habitat loss, pollution and climate change. Conservation efforts are crucial to protect these valuable creatures and their vital role in the ecosystem. In this context, yes, a biological pool could be part of the solution, because it provides a new habitat.
