	abstract = {<p>Our recent surveys of the herpetological diversity of the West African Togo Hills documented a total of 65 reptile and amphibian species, making Kyabobo National Park one of the most diverse sites surveyed in Ghana. We provide accounts for all species recorded along with photographs to aid in identification. We recorded 26 amphibians, including six new records for Kyabobo N. P., one of which is a record for the Togo Hills. Our collection of reptile species (22 lizards, 16 snakes, and one crocodile) also provides new records and range extensions for Kyabobo N. P., such as the first observation of the dwarf crocodile, Osteolaemus tetraspis. Amphibian species still lacking from our surveys in the Togo Hills include several species that are adapted to fast running water or large closed forests, like the Togo toad, Bufo togoensis and the slippery frog, Conraua derooi. Appropriate habitat for such species still remains in Kyabobo, highlighting the need for additional survey work. We draw attention to the importance of conserving forest stream habitats, which will in turn help ensure the persistence of forest-restricted species. We also highlight those species that may prove most useful for evolutionary studies of West African rain forest biogeography.</p>

	abstract = {<p>We report on the results of our assessments of amphibians in the forests of southern Ghana and western Togo. During two surveys in 2005 (Ghana) and 2007 (Ghana and Togo), we recorded at least 45 frog species. These included first country records for Ghana (Kassina cf. cochranae) and Togo (Hyperolius sylvaticus sylvaticus), and several species that had not or only rarely been found after they had been described, e.g. we herein report the rediscovery of Conraua derooi. A high percentage of the recorded frog assemblages consisted of species endemic to the Upper Guinea forest, to Ghana or even a particular region within Ghana (and Togo). The majority of species was closely associated with forest habitats. Nevertheless, in some forest areas the presence of savanna and farmbush species indicated serious habitat degradation. This situation was particularly obvious in the Togo-Volta Highlands. The fact that one third of the encountered amphibians were threatened highlights the importance of the forest ecosystems of southern Ghana and western Togo for the maintenance of the regional biodiversity. However, our results also indicate the urgent need to protect these forests more efficiently.</p>
