The Camargue bull breeding consists of extensive breeding in marshy areas where the herds known as manades are gathered by herdsmen on horseback in accordance with tradition. The herds live in semi-freedom in vast areas mostly inaccessible by car. The only European breed capable of living on brackish water pastures, the Camargue bull is relatively autonomous. The rare human interventions concern the branding of calves, the herd regrouping for animal sale, health surveillance, and the potential distribution of food supplements.
