A, Coast rhododendron (Rhododendron californicum), native to the Pacific coast, reputed to be poison- 
ous to sheep, but the herbage is not grazed when sufficient palatable vegetation is present. Photo- 
graph taken on the Santiam National Forest, Oreg.; B, big whortleberry (Vacciniwm membrana- 
ceum), one of the commonest and (relatively) most palatable of the western huckleberries. Photo- 
graph taken on the Wallowa National Forest, Oreg.; C, red mountain heath (Phyllodoce empetri- 
formis), common in moist sites on high peaks of the far West. Ptarmigan are fond of the flowers. 
The herbage is normally unpalatable to livestock; if cropped to a considerable extent it causes 
sickness. Photograph taken on the Deschutes National Forest, Oreg.
