摘要：The herpetofaunal species in Ghana are under serious threat from habitat loss and degradation, global climate change, disease and parasitism, introduced invasive species and unsustainable use. The herpetofaunal species of the Kogyae Strict Nature Reserve of Ghana were surveyed using two methods: refuge examination via direct searches, visual/audio surveys and interviews of local residents. Data were obtained during two visits to two study sites in 2012: savanna woodland and riparian forest mosaic. The first visit was in the dry season in January, 2012 for five days and the second visit in the rainy season in June, 2012 for six days. Thirty-six herpetofaunal species were recorded, comprising of 14 amphibians and 22 reptiles. Ten of the reptiles were recorded only from interviews. The savanna woodland recorded a higher number of species (33) than the riparian forest mosaic (22), and there was low similarity in species between the two sites (Sorenson’s similarity index, CS = 0.42). Four species were frequently encountered at both sites in high numbers: Phrynobatrachus natalensis, Phrynobatrachus latifrons, Arthroleptis spp. and Trachylepis affinis. Two lizard (Varanus niloticus and Varanus exanthematicus) and two snake (Python sebae and Python regius) species are of both local and global conservation significance. The lizards are categorized under Schedule I (complete protection) and the pythons under Schedule II (partial protection) of the Ghana Wildlife Conservation Regulations. The main threats to the herpetofaunal species of the study area include habitat destruction due to annual bushfires and killing of large reptiles like the monitors as well as snakes. It is recommended that riparian vegetation bordering streams should be particularly targeted to conserve herpetofauna of the study area.
