The municipalities of Porto Alegre and Viamão in southern Brazil are characterized by a mosaic of natural and urban elements within an ecotone between the Atlantic Forest and Pampa biomes, where populations of brown howler monkeys (Alouatta guariba) occur. Urban expansion has led to the fragmentation of natural habitats and an increase in conflicts between human populations and howler monkeys, with electrocution being the most frequent type of conflict. This study aimed to quantify rescues and veterinary interventions involving brown howler monkeys between January 2018 and December 2024, with a focus on electrocution cases. Conflict data were obtained from the database of the Programa Macacos Urbanos (PMU/UFRGS), in collaboration with public wildlife management and rescue agencies and local residents. We compiled 365 records of anthropogenic conflicts involving brown howler monkeys in these municipalities. Electrocutions (n = 116) were the leading cause of incidents, followed by dog attacks (n = 64) and vehicle collisions (n = 26). Electrocution cases increased over time, particularly between 2022 and 2024. Individuals referred for veterinary treatment due to electrocution-related injuries remained hospitalized for an average of 88 days, with a mean cost of R$4,949.87 per individual during this period. The estimated cost of maintaining an individual permanently in captivity was approximately R$412,000. These data were submitted to the Judiciary to support a Public Civil Action aimed at reducing electrocution-related mutilations and mortality in brown howler monkeys. The development of public policies, the establishment of a community-based protection network, and inspections of electrical infrastructure in collaboration with the energy utility company are key mitigation measures to reduce conflicts involving electrocution.
