Les barthes de l'Adour

Along the bed of the Adour, the barthes are undeveloped wetlands. They extend from Tarnos to Pontonx over nearly 12,000 hectares and have the particularity of being frequently flooded by runoff from the hillsides, rising alluvial water tables and the overflow of rivers. These exceptionally rich areas offer a diverse natural habitat: tree bats, wood-eating insects, otters, cistude and European mink, and marsh copper (a butterfly that breeds on sorrel) are all species that can be found in our Adour barthes. Worked by Man from the 18th century to be drained and cultivated, they are still today crossed by dykes, canals and ditches. At the bend of the Path of Adour, between Gousse and Goos, you will be able to observe the storks which nest at the year between Gousse and Préchacq.
