Distribution of Sierra mountain misery (Chamacbatia foliolosa) and cliff- rose {Cowania mexicana var. stansburiana). Mountains to the Providence Mountains of San Bernar- dino and Inyo counties. It occurs rather commonly in the Joshua tree and pinon-juniper associations. It extends eastwards to New Mexico and southward to Mexico; usually occurring in scattered stands. Cliffrose freely hy- bridizes with both species of bitterbrush. Economic value. One adverse factor as a browse plant is that the older branches are so brittle that hungry ani- mals often break them, thus sometimes decreasing its yield and vigor perceptibly. On cattle or sheep range overutilization of cliffrose is likely to be browsed to the extent of its extermination if the animals are not prop- erly distributed or if the grazing season is overly long (photo on the right). Another unfavorable factor is its rather restricted distribution. The high selectivity of cliffrose by grazing animals places it in the category of a fairly important food plant. It is also utilized closely by deer and desert bighorn sheep. Browse rating. Excellent to good for deer; good for goats; good to fair for sheep; fair to poor for cattle; and poor to useless lor horses.
