Invasive species pose significant threats to ecosystems and biodiversity, necessitating effective management strategies to mitigate their impacts. One such invasive species of concern is the wild boar in Brazil, which has the potential to cause widespread environmental changes. A national plan for monitoring and controlling invasive species, including the wild boar, was developed in response to this threat. Despite this initiative, uncertainties persist regarding the presence of wild boars in protected areas (PAs) and the effectiveness of current management actions. This study aimed to diagnose the situation of wild boars in protected areas within the southern region of Brazil, specifically focusing on their distribution, management techniques employed, and reasons for the lack of management action. An online questionnaire was sent to 297 PAs, with 134 responding. The findings revealed that wild boars were present in 39 of the surveyed PAs, but management efforts were only being carried out in 14 of them. Cages and corrals were identified as the most commonly used techniques, with corn serving as the preferred bait. The study identified two primary reasons for the lack of management action: the wild boar's low invasion intensity and management capacity limitations. To address these challenges effectively, the study advocates for a centralized organization of management actions and emphasizes the development of materials and resources to support successful management strategies. Implementing these measures is essential to safeguarding the conservation of ecosystems and vulnerable species in Brazil's protected areas and ensuring the long-term resilience of these valuable ecological assets.
