The populations of some rare species, very often objects of poacher's hunting, are in danger of extinction--for example Bonasa
bonasia and Tetrao urogallus;
Poudrier, is a collection of sporting stories published in a style reminiscent of early 20th century sporting books, with leather covers and gold leaf embellishments according to Bonasa
umbellus, distribution, Indiana, population status, ruffed grouse
The project s main objective is to re-establish favourable conservation status for five priority species listed in the Birds Directive (Tetrao urogallus, Bonasa bonasia, Dendrocopos leucotus, Picoides tridactylus, Haliaeetus albicilla), one priority species listed in the Habitats Directive (Proteus anguinus) and a priority habitat type listed in the Habitats Directive (caves not open to the public, 8310).
Disturbance in the habitat of Tetrao urogallus and Bonasa bonasia will be reduced by establishing 600 ha of quiet zone ;
frenata, American martens Martes americana, snow-shoe hares Lepus americanus, red foxes Vulpes vulpes, coyotes Canis latrans, ruffed grouse Bonasa
umbellus and dusky grouse Dendragapus obscurus.
32 Bombycilla cedrorum -- -- -- -- Bonasa
Of the 701 carcasses that we observed wolves to have fed on, 91% were white-tailed deer, 4% were snowshoe hare Lepus americanus, 3% were grouse Bonasa
umbellus and Falcipennis canadensis and 2% were beaver Castor canadensis.
Species monitored the most frequently were wild turkey Meleagrisgallopavo (N=34; 72%), ruffed grouse Bonasa
umbellus (N = 30; 64%), ringnecked pheasant Phasianus colchicus (N = 28; 60%) and northern bobwhite (N = 24; 51%; Table 4).
Otherwise, black grouse and hazel grouse Bonasa bonasia had a significantly greater proportion of total hits in BIOSIS than in WOS, blue grouse Dendragapus obscurus and spruce grouse Dendragapus canadensis vice versa.

The study species is the hazel grouse Bonasa bonasia, a habitat specialist with poor dispersal ability and therefore likely to be strongly affected by habitat fragmentation (Andren 1994, With & Crist 1995).
