"Agriculture has been declining for several decades in the municipality of Villaroger because the sloping terrains are not favourable to mechanisation. The alpine meadows of Trousse (called the ""mauvais prés"") and their upper part, which are dependent on the mountain pasture of Martin, illustrate this reality. Where once hay was formerly used, agriculture is still maintained today with herds of goats and heifers which make it possible to prevent these alpine pastures from being filled with green alder."
