1243.0 Flore: Le Buis Le buis est un arbuste doté de feuilles persistantes de petites tailles, ovales et d'un vert foncé. Le buis a une croissance lente. Les troncs d'une quinzaine de centimètres de diamètres sont déjà de vieux arbres. Les forêts où prédomine le buis sont appelées des buxaies. Dans les vallées entre Luz-Saint-Sauveur et Gèdre, la buxaie occupe une grande partie des pentes boisées jusqu'à environ 1200-1300m d'altitude. Elle forme des couverts végétaux très denses, quasiment impénétrables. Les buxaies de la vallée constituent un élément remarquable et identitaire du paysage local. Les buis de nos vallées sont malheureusement menacés par la chenille de la Pyrale du Buis, une espèce de papillon de nuit invasive arrivée d'Asie il y a quelques années. [Itinéraire] Enduro n°112 - Le col de Ripeyre Après une mise en jambe ludique vers le quartier de Bent, la longue ascension vers le col de Ripeyre emprunte une piste dans la sauvage forêt de Barrada. La descente ? Un régal pour pilotes émérites dans la première partie, où l’expertise dans le placement de roue avant et l’engagement dans les courbes serrées sont de précieux avantages. Sur le final, plus de fluidité sur un sentier labyrinthique dans un couloir de buis, un grand moment ! La descente débute par un sentier étroit sur l’autre versant, parfois sur blocs fuyants. La trace entre dans un bois clair par des épingles serrées, et toujours une pente soutenue.Modifié: 44 semaines 1008.0 1008.0 1009.0 1009.0 1010.0 1011.0 1012.0 1013.0 1014.0 1015.0 1016.0 1017.0
