Excavations at both Kokkinopilos and the Cave of Asprohalkou have both shed light on the important role the Louros River Valley area played in prehistoric times. Experts believe that the river supported an abundant range of wildlife that enabled groups of hunter-gatherers to survive in the area over centuries. Today the river continues to support a diverse variety of birds, fish mammals, reptiles and amphibians in the area. Otters, moles, wild cats, Mediterranean, Rock and Swamp Turtles, toads and frogs are just some of the animals that depend on the Louros River for their sustenance. Within the river, eels, Trout, and other species of fish flourish, though during the last few decades, their numbers have been reduced due to the severe pollution problem the river faces.
