Abstract
Three-and-a-half years of (mainly passive) observations disclosed the fact that the Kaliveli watershed area is inhabited by at least 268 species of vertebrates. The greatest majority were birds (55.11%). They were followed by fish (18.28%), mammals (14.17%), reptiles (13.8%) and amphibians (2.61%). The conservation value of only 105 species could be determined - 1 Endangered, 12 Vulnerable, 55 Near Threatened and 37 of Least Concern. The only exotic was Oreochromis mossambica, an alien invasive species.
