 | | In winter, fl grouse feed on shrubs such as Vaccinium, Calluna, and Juniperus and, if these are snow-covered, they rely on catkins, buds, twigs, and needles of various tree species, especially birch, alder, and willow, but also spruce and pine. |
 | | Drainage and destruction of moorland, fertilisation or afforestation of heathland and sheep pastures, and the declining use and maintenance of alpine summer pastures by grazing and mowing are common causes of the deterioration of fl grouse habitats. |
 | | Locally, however, reserves are seen as vital for fl grouse conservation: In Belgium, the Netherlands, and northern Germany, most remaining populations are in nature reserves (or military training grounds, which have similar effects), which are considered to be critical for their survival. |
