The Pays de Buch is part of the Landes Forest and the landscape is composed principally of maritime pines. Most of these pine trees were planted in the nineteenth century, except for the working forest of La Teste-de-Buch, which is natural. In the humid areas and near bodies of water like the shores of the Eyre River, the pines form a rich substrate for vegetation.^{[citation needed]}

The lands near the ocean are marked by active dunes, fixed in part by people at the end of the nineteenth century. Further inland, old dunes are oriented in a north–south line and the forest is slowly recovering them, extending a dozen kilometers west–east. Across this dune corridor is the sandy plain of Landes.^{[citation needed]}

The Arcachon Bay is, a large gap in the forested plain, offers a great variety of landscapes: salty marches at the bank of Arguin, the Dune of Pyla, and the Isle of Birds. The bay is the mouth of the Eyre River and receives the fresh water of the area.^{[citation needed]}
