The lands of the Pont de Rousty estate are spread around the farmhouse, consisting of farm buildings, houses and the administrative center of the Camargue Regional Natural Park. The cultivated plots are the closest to the mas located on the alluvial ridge of the old Rhône d'Albaron. Agricultural areas play an important role for biodiversity, especially rice fields as feeding grounds for birds (herons, ibis in summer, cranes in winter).
