由于俄勒冈州艾草松鸡（Centrocercus urophasianus）的丰度和生产力长期下降，我们在2个研究区调查了植被覆盖与艾草松鸡筑巢的关系。在未被捕食的巢穴周围（x = 6%）或随机位置（x = 3%），中等高度（40-80 cm）的灌木覆盖（P = 18 cm）和残留草覆盖（P < 0.001）在未被捕食的巢穴周围（x = 6%）更大（x = 3%）。
Because of long-term declines in sage grouse (Centrocercus urophasianus) abundance and productivity in Oregon, we investigated the relationship between vegetational cover and nesting by sage grouse in 2 study areas. Medium height (40-80 cm) shrub cover was greater (P 18 cm), residual grass cover was greater (P < 0.001) at nonpredated nests (x = 18%) than in areas surrounding nonpredated nests (x = 6%) or random locations (x = 3%)
