It is a herd of sheep from the village of Sollières which has its summer quarters on the alpine pasture of the Loza. Since the return of the wolf, a wooden chalet has been built providing shelter for the shepherd who stays there on a daily basis to ensure the safety of his flock. The Alpage de la Loza benefits from a contract between the farmer, the Chamber of Agriculture and the Park to lead agro-environmental measures conciliating pastoralism and the protection of species.
