Overview

• A pilot relocation of three high-risk capybara families, totaling 70–80 animals, is scheduled for late August on a 60-hectare Delta island pending provincial approval and financed by Nordelta SA.
• About 300 male capybaras received the first dose of a two-shot contraceptive vaccine earlier this year, with second injections planned for August to secure one-year fertility control.
• Scioli has engaged SENASA to expedite the local approval and importation of a single-dose contraceptive vaccine already used in the United States and Europe.
• Authorities say the combined measures aim to reduce wildlife-vehicle collisions that claimed 43 capybaras in Nordelta during the first half of 2025.
• Environmental groups like Carpinchos de Nordelta oppose the relocation plan, warning it could endanger both translocated and resident capybaras in the new habitat.
