Other Site Characteristics

Le Réseau hydrographique du Midou et du Ludon présente une diversité d'habitats relativement importante, malgré une faible représentativité des habitats d'intérêt communautaire. Sur l'ensemble du site de grandes surfaces sont recouvertes par les boisements, pour la plupart non communautaires, et par des habitats artificiels tels que les cultures ou les plantations de ligneux. Les habitats typiques et directement liés à la rivière (herbiers aquatiques, prairies humides, ripisylve …) sont en régression ou ont quasiment disparu sous l'influence des différents usages et pressions anthropiques. Qualité et niveaux d'eau, changement dans les spéculations agricoles. Dynamique de dégradations des conditions écologiques et fonctionnelles des zones humides et des cours d'eau.
