Capybaras are the world's largest rodents and highly social semi-aquatic mammals whose welfare in the wild depends on access to water, stable group living, and intact South American wetland habitats.
Capybaras are remarkable social animals whose wellbeing is deeply tied to the stability of their group structure and the quality of their aquatic habitat. In the wild, social bonds within capybara groups provide protection from predators, cooperative care of young, and social stimulation. Disruption of these groups through hunting pressure or habitat fragmentation causes welfare harms that extend beyond individual animals to entire social networks. Wetland degradation eliminates the water access that is fundamental to capybara thermoregulation and behavior. Conservation of South American riparian and wetland ecosystems through protected areas and sustainable land use planning is essential for wild capybara welfare. In some regions, capybaras have adapted to human-modified landscapes including golf courses and urban parks, creating new welfare considerations around human-wildlife coexistence.
