dc.description.abstractThe Wolf Marine Iguana is found on the islands of Wolf, Darwin, and Roca Redonda in the Galápagos Islands, Ecuador. The estimated extent of occurrence is 1,058 km2 by minimum convex polygon and the area of occupancy is estimated at 16 km2 using a 2x2 km grid overlay. The population size is poorly known and estimated at 600–2,300 total iguanas, with fewer than 1,380 mature individuals. Overall population trend is unknown, but is subject to extreme reductions and fluctuations during El Niño events, which are predicted to intensify in the future with ongoing climate change. Wolf Marine Iguanas are threatened by a region-wide increase in human population and visitation that has multiplied the impacts from marine pollution, habitat degradation, and chance of invasive species introductions and emergent diseases. This subspecies qualifies for listing as Endangered.
