Symphoricarpos spp. 



All species may be propagated by soft or hardwood cuttings cut below the node 

 and treated with potassium permanganate, or they may be propagated by seed. 

 Many species contain small amounts of saponin, but such large quantities are 

 necessary to cause acute poisoning that cases of livestock poisoning are rare. 



Stomach records (in addition to specific records) : Twenty-six species of birds, 

 including ruffed grouse, dusky grouse, sharp-tailed grouse, ring-necked pheasant, 

 and California quail ; black-tailed deer, plains white-tailed deer. Observations 

 (in addition to specific records) : Six species of birds ; much eaten by ring- 

 necked pheasant; Hungarian partridge; pica, Columbian black-tailed deer. 

 Extremely important browse for livestock in Utah, Nevada, and southern Idaho ; 

 cases of livestock sickness charged to this genus appear to be extremely rare.
