The areas of habitat suitable for the Lyre Grouse are also suitable for pastures because of their biological richness. The presence of small herds used to be an effective way of maintaining these habitats: it was a two-way street beneficial relationship.
When mountain farming was abandoned, this fragile balance broke down. Since 2014, the Nature Reserve has been clearing vegetation to artificially substitute grazing previously done by domestic animals, thereby restoring the natural habitat that supports the reproduction of this galliform.
