Project No.: 7879140169 Report Issue Form APPENDIX 16 HERPETOLOGY REPORT ESIA REPORT, YAOURE GOLD PROJECT JUNE 2015 E X E C U T I V E S UMMARY Background - The following report summarises the rapid assessment conducted within the Yaoure Gold Project concession to gather baseline data for reptiles and amphibians. The survey took place from the 1st to the 21st of May 2015 and was commissioned by Amec Foster Wheeler Earth & Environmental UK Ltd for Amara Mining Côte d’Ivoire SARL. In total, 35 species of reptiles and 29 species of amphibians were recorded. Methods - Reptiles and amphibians were searched via visual and acoustic encounter surveys in suitable habitats. Trapping with drift fences and funnel traps at two sites supplemented the records. Complementary information was gathered through interviews, especially to assess crocodile presence in the area. Main findings - No regional or national Red Lists are publicly available. None of the recorded species are currently listed as threatened by the global IUCN Red List. Nine species of reptiles are of conservation concern because they are either regularly harvested (Bitis arietans, Bitis rhinoceros, Pelusios castaneus, Chamaeleo gracilis, Python sebae, Python regius, Varanus niloticus; the last four species are listed in CITES Appendix II) or have restricted ranges (Hemidactylus fasciatus, Hemidactylus cf. muriceus). The latter two species are also indicators for forests. Three species of amphibians are also of conservation concern due to their restricted ranges (Afrixalus vittiger, Hyperolius igbettensis, Kassina schioetzi). Four specimens of reed frogs (Family Hyperoliidae: Hyperolius sp.) cannot be assigned to any known species yet. Further research is needed to verify whether they might be a new species. Overall, the concession contains a diverse herpetofauna because it is located at the transition zone between the biomes forest and savannah. A number of species of reptiles (n=39) and amphibians (n=18) were not recorded during the present survey but are known from this region of Côte d’Ivoire. The absence of larger patches of good humid forests from the study area might be the main explanation for the absence of many forest dependent species. Impacts - Artisanal and industrial mining activities have been on-going throughout the concession for several years and have significantly altered the vegetation and landscape so that many species are confined to the remaining natural small forest or savannah patches. Thus the site is already impacted but a further increase in habitat degradation is expected with further developments. The main recommendation is to raise awareness on the importance of biodiversity at the mine site but also in the area in general as well as to start coherent environmental and offset planning as soon as possible.
