Distribution of western chokecherry (Prunus virginiana var. demissa). northward in the Coast Ranges; in the Sierra Nevada to the mountains of northern California; and northward to British Columbia; eatsward to Nevada and Arizona. Economic value. Western chokecherry is probably the best known member of the genus Prunus in California. The fruit is edible but astringent; more palatable to browsing animals than some other Prunus species; and apparently accounts for more sheep losses from poison- ing than any other species of the rose family'10* as>. Tin's variety is closely browsed by deer but is also sought by sheep and goats. Cattle feed upon it little ex- cept where the range is overgrazed. Analyses indicate that the crude protein levels are similar to those of asso- ciated deciduous shrubs, ranging from about 16 per cent early in the season, per cent in mid-summer, and per cent in early fall""". The protein content of the current stems for the same periods are per cent, per cent, and per cent respectively. The lignin con- tent is higher than average for most shrubs, whereas the calcium to phosphorus ratios are not strikingly dispro- portionate for the three periods mentioned. Although western chokecherry is very poisonous at certain growth stages, whole bands of sheep are seldom affected; rather only individual sheep become ill or die. The quantity of leaves required to poison one sheep varies with season, size of animal, amount of moisture contained in the leaves, amount ol forage in the stomach, and rapidity with which the leaves are eaten. Browse rating. Excellent to good for deer; good to fair for cattle; fair to poor for sheep and goats; and useless for horses. Western chokecherry (Prunus virginiana var. demissa) is browsed with relish by livestock and deer. Poisoning of hungry sh
