EFFECT OF GRAZING ON WESTERN YELLOW PINE. Dif 
as little as possible; that, wherever practicable, they be closed to 
grazing except by passing stock; that a sufficient number be estab- 
lished to prevent overgrazing; and that water be furnished in abun- 
dance at proper intervals along them. 
Kvery effort should be made to protect yellow-pine reproduction in 
the “twilight” zone between the yellow-pine type and the juniper- 
pinion type. Conditions here are unusually unfavorable for yellow- 
pine reproduction, and such seedlings as become established should by 
all means be protected against grazing. 
Stock, especially sheep, should not be held in the yellow-pine type 
during the winter, when they would be forced to eat reproduction. 
Advantage should be taken of grazing as a means of fire control 
by securing proper utilization of all range where at present an 
accumulation of inflammable unused feed occurs each year. Such 
areas are common on the bunchgrass type and on other types of 
range far removed from water or located on rough ridges and slopes.
