Threats and conservation

Forest on the peninsula continues to be exploited by the human populations. Fire has already destroyed Analavory Forest, leaving Ankarafa and Anabohazo the largest areas of intact forest in Sahamalaza. These two locations are subject to high levels of forest clearance to make way for crop cultivation and pastureland (Penny et al., 2014, 2016). Furthermore, fires lit in the dry season to rejuvenate grazing land frequently spread out of control and burn adjacent areas of intact forest. Selective logging of tropical hardwoods and small-scale quarrying were also observed in Anabohazo Forest, although currently this is still the more intact of the two remaining forests. If actions, such as those outlined by a recently published conservation action plan on the amphibians of Sahamalaza (Penny et al., 2016) are not promptly implemented, then all the peninsula’s forest dwelling herpetofauna will suffer serious population declines and the local endemics will be pushed towards extinction.
