STOCK DRIVEWAYS. 



During the fiscal year ended June 30, 1917, a total of 2,176 permits 

 Avere issued, allowing 56,95-1 head of cattle, 1,118 head of horses, 

 3,385,429 sheep, and 47,897 goats to cross National Forest lands 

 en route to and from the ranges used by the respective permittees. 

 The number of stock which uses the National Forest lands in this 

 capacity varies little from year to year. There ma^'' be a slight 

 decrease in the future, but it will be necessary to provide crossing 

 privileges for at least 3,000,000 head of stock each year for a number 

 of years, and for nearly this number permanently. The distances 

 that the stock are driven vary from perhaps less than 1 mile to about 

 125 miles. It is evident, therefore, that a considerable acreage must 

 be devoted to this phase of range utilization. It is equally evident 

 that on every National Forest where grazing is an important activity 

 a great deal of attention should be given to getting the stock to their 

 allotted range with the least injury to timber growth, watersheds, 

 and the range, and with the minimum interference with proper graz- 

 ing use of range along the way. 



Driveways have been established over portions of the National For- 

 ests where it is necessary for stock to cross regularly. Many of these 

 driveways have been in use for a number of years and show the ill 

 effects of premature grazing, overgrazing, and trampling. Hill,^ for 

 example, re^Dorted on this subject as follows : 



One of the most serious menaces to reproduction (western yellow pine), as 

 well as to range, occurs on stock driveways. Even at best an excessive number
