Site description Aux Bec-Croisé is situated in Plaine Boeufs on the Chaine Formond south of Duglacis, 1850 meters above sea level overlooking the Grande Ravine du Sud, near the area of Ti Chien. It is close to Kay Tilus, Kay Ogile and on the way to Duglacis where the small growing population grows staple food on state land since the 1950's. Several men in this region are timbermen.

Key Biodiversity Although as not rich as in the karstic zones areas, Aux Bec-croisés shelters Hispaniolan Crossbills and the Western Chat-Tanager. Species diversity also increased in winter months when migratory birds arrived from northern latitudes. Last inventory was on February 2004 which included mistnetting, sight counting and banding all day from 5:00 pm to 7:00 pm. Bird species of special concern are Western Chat-Tanager (Calyptophilus tertius), Bicknell's Thrush.

Non-bird biodiversity: The Chaine of Formond is the center of biodiversity for the genus Mecranium and shelters plants that are restricted there such as Ekmaniocharis. Due to frequent fires in the lower areas and absence of prescribe fires, metrological station and knowledge, many species might face threats, since one a forested area is opened or clear, farmers tend to appropriate these land.
