noted near Oro Blanco in Cedar Creek Canyon, where the trees range from 
20-30 cm. in diameter at breast-height, 39 showed vigorous sprouting. 
The trees had been cut by the axe, and the stumps were 30-75 cm. in 
height. In this canyon a count of roo trees, broken off by cattle, which 
had stump diameters of 2.5-5 cm., 
produced very strong sprouts, with 
the exception of two trees which ha 
been killed outright. The sprouts 
ranged from 15 to 120 cm. in height, 
according to age, site, vigor of tree, 
and number of sprouts to the stump. 
The most noteworthy example was 
These sprouts were 2 meters tall and 
had basal diameters of 3.75-6.25 cm. 
On the west slope of the Pata- 
gonia Mountains another count of 50 
Stools showed only 6 failures; 4 were 
stumps which were over 20 cm. in 
diameter, and 2 had been killed by fire. 
All stumps below 5 cm. in diameter 
were producing thrifty sprouts. Two 
stumps 15 cm. in diameter and 30 cm. 
tall were producing respectively 63 
and 166 sprouts, while a third stump 
12.5 cm. in diameter and 35 cm. tall 
Was supporting 256 sprouts. Generally 
3-10 sprouts are produced on each 
stool, and not more than 1-3 of the

Juniper showed serious injury by livestock, which was almost invari- 
ably followed by sprout recuperation. In the vicinity of the Mowry 
Mine and in the Huachuca Mountains the injury to reproduction varied 
from 80 to 100 per cent. Throughout the entire region examined, the 
Species showed its ability to reproduce by coppice, especially when the 
trees were less than 20 or 22.5 cm. in diameter.
