Abstract
Protected areas play a fundamental role in the preservation of species, environmental education, and ecosystem services maintenance. Most of the world population live in urban areas, which highlight the importance of preserved areas in urban centers. However, many urban protected areas in Brazil lack species surveys, which limits biodiversity conservation and implementation of management plans. In this study, we surveyed the species of medium and large mammals of Chico Mendes Municipal Natural Park (MNP) and Canal das Taxas corridor through camera traps, thus providing the first comprehensive in situ survey of terrestrial mammals for the area. We also verified whether there was mammalian fauna exchange between the Chico Mendes and Marapendi MNPs through the vegetation corridor formed by the Canal das Taxas. Between November 2020 and July 2021, with a sampling effort of 1,334 trap-days, we recorded five native and five exotic species in the studied areas, including one Vulnerable species in the Municipality and State of Rio de Janeiro (Cuniculus paca). We also confirmed that Canal das Taxas works as a wildlife corridor for native species. Finally, we highlight that species checklists based on secondary information for the region are of limited usefulness and recommend in situ surveys even in small, urban protected areas of Rio de Janeiro city.
