Amphibians and Reptiles of Ethiopia—Biogeography, Conservation Priority Areas, and Potentials for “One Plan Approach” Conservation Measures

ABSTRACT Ethiopia, as one of 36 global hotspots of biodiversity, provides diverse habitats for a variety of species, but little research about the herpetofauna of the country is available. Worldwide, especially amphibians but also reptiles, are threatened by biodiversity and habitat loss due to deforestation and other human actions. Following the One Plan Approach by the International Union for Conservation of Nature, an integrative use of ex situ and in situ measures is recommended to address the ongoing conservation crisis, which is currently largely missing for Ethiopia's 76 amphibian and 191 reptile species. In an effort to close gaps in conservation work, we analyze species richness, protected area coverage, and corrected weighted endemism as well as the threat status and status of ex situ populations for these species. We show the South‐Western lowlands as the most important region of high species diversity and threatened and endemic species, having a species richness of 12–14 for amphibians and 50–54 for reptiles. Additional important hotspots are the South‐Western Highlands and Arsi‐Bale Highlands; the protection of these three regions should be prioritized. For protected areas, the Bale Mountain National Park is particularly important, sheltering 25 amphibians, 7 of which are threatened and 8 endemic, as well as 2 endemic reptiles. The Arsi Mountains National Park also houses a large number of species, with many threatened and endemic ones. Although many priority areas are already under protection, the extension of existing and establishment of new protected areas, for example, in the Southern and South‐Western Lowlands, would be advantageous for species conservation. With only 3 amphibian and 43 reptile species in holding, largely with low number of institutions or individuals, representation of Ethiopian species in ex situ facilities is insufficient and priorities should be shifted to endemic and threatened species and the building of breeding programs. For conservation‐oriented holding stations and zoos, a list of the 33 most threatened amphibian and reptile species is provided.
