- Effectiveness of protected areas and restricted access in sandy beach biodiversity conservation: A case study from Rio de Janeiro, Southeast Brazil. Augusto, Matheus Abude, Rayane R S Cardoso, Ricardo S Nascimento, Rodolfo L Valentin, Jean L Cabrini, Tatiana M B Brazil Biodiversity Conservation of Natural Resources Bathing Beaches Animals Environmental Monitoring Ecosystem Sandy beaches are important socio-ecological systems for human well-being and coastal stability. They are also economic and cultural assets; however, urbanization and human activities threaten their ecosystem services and biodiversity. Thus, it is important to discuss strategies for ecosystem conservation. The main objective of this study was to evaluate the effect of different degrees of spatial protection (Protected Areas - PA vs Restricted Access - RA) on the macrofauna of sandy beaches in Rio de Janeiro, Brazil. Beaches were sampled in 2012 and 2020, before and after PA implementation, and compared to beaches with Restricted Access (RA). Results revealed that RA beaches supported higher macrofaunal density and species richness, including indicator species, compared to PAs. These findings suggest that RA areas are more effective in conserving sandy beach macrofaunal communities than PAs with unrestricted public access. While beaches are vital for human well-being and recreation, proper management of human activities within PAs is essential to safeguard biodiversity and maintain ecosystem services.
