Local knowledge and use of the valle de aguán spinytailed iguana, Ctenosaura melanosterna, in Honduras

Abstract

The harvesting of wildlife has had a devastating effect on global biodiversity. Here we investigate the perceived status of the Critically Endangered Valle de Aguán Spiny-tailed Iguana, Ctenosaura melanosterna. We interviewed 132 residents of the Valle de Aguán, Honduras to: (1) examine their knowledge of the range and habitat preference; (2) document the use and trade; and (3) understand the level of awareness and openness to protection of this species. Our results indicate that these iguanas are primarily used for food. Though they are a small component of the local diet, consumption is occurring with a preference for gravid females. There are significant gender and geographic differences in consumption by humans. Though these harvesting actions contribute to the continuing decline of this species, our results demonstrate that there is a local belief that these iguanas are in danger of extinction, that conservation actions should occur, and that international involvement is welcome.
