Rediscovery of Pteronura brasiliensis in the Amanã Sustainable Development Reserve, Amazonas, Brazil

Abstract


This research describes efforts to confirm and document the presence and distribution of giant otters in the Amanã Lake and surrounding creeks, where the species was considered locally extinct due to extensive historical culling. Fieldwork was conducted during the dry season, and consisted of surveying small creeks and shallow aquatic areas in the Amanã Lake by boat and canoe. Two teams, guided by local inhabitants, conducted the survey simultaneously. The spatial distribution of the species was recorded based on signs of presence. Only one giant otter sighting was recorded; however, a considerable number of giant otter signs was found. The study documented the reappearance of the species in the Amanã sector of Amanã Sustainable Development Reserve.
