Protective limits are established to protect permittees from reduction in the number of stock which they are allowed to graze under permit below a point where the business becomes too small to be handled at a profit or to contribute its proper share toward the maintenance of a home. The average number of stock which a settler must graze in order to utilize the products of his farm and derive a reasonable profit is determined upon each Forest or, if necessary, upon each grazing district thereof, and serves as the basis for the protective limit. Protective limits have been established for various Forests running from 25 to 300 head of cattle and from 500 to 2,000 head of sheep and goats.
Increases above the protective limit are allowed only to purchasers of stock and ranches of permit holders and any such increase must not exceed the maximum limit. Class A permittees owning a less number of stock than the protective limit are allowed to increase their number gradually. Whenever it is found necessary to reduce the number of stock allowed in any National Forest, Class C stock is excluded before the other classes are reduced. The reduction on a sliding scale is then applied to Class B owners. Class A owners are exempt from reduction. When new stock owners are allowed the use of National Forest range upon a Forest already fully stocked, reductions in the number of permitted stock of Class B and C owners is made in order to make room for the new man. Thus it is seen that the matter of protective limits is actually a protection to the small stock owner; he is protected from the monopoly of the range by big corporations.
When necessary to prevent monopoly of the range by large stock owners, the District Forester establishes maximum limits in the number of stock for which a permit may be issued to any one person, firm or corporation.
