The Natura 2000 site "Coteaux du Lizet et de l'Osse" has a surface area of 1 865 hectares. Delimited by the Osse and the Lizet, it concerns the communes of Montesquiou and Saint Arailles

The site presents a significant landscape diversity and many varied habitats typical of the hillsides of the Astarac. Different representations of dry grasslands can be found. They are particularly rich in orchids (Scented Orchid), and are home to many Mediterranean plant species (Broad-leaved Lavender).

These lawns are intertwined with woodland and hedged areas that are favourable to bats. A large population of butterflies colonise the dry hillsides and valley bottoms (Marsh copper) and around the ponds one can observe numerous dragonflies and even the European pond terrapin, the emblematic turtle of the department.

The Lizet hillsides are typical of the rugged landscape of the Astarac: the rivers cut out valleys with an asymmetrical relief and a contrasting geology. Steep limestone slopes occupied by woods, moors and meadows dotted with numerous hedges, face gently sloping, cultivated silty slopes.
