To the south of the Courant de Contis lies the Plaine de Pigeon. It is a vestige of the wetlands drained at the end of the 19th and beginning of the 20th centuries. Managed by the ACCA of Lit et Mixe and the departmental hunting federation, this site is home to a wealth of biodiversity unique in the Landes. This breeding ground for rare species is home to several species of orchids, as well as the marsh stellar, a rare herbaceous plant in the Landes massif.
