RANGE MANAGEMENT ON THE NATIONAL FORESTS. 77 



tion ? Where a general movement of stock from one unit to another, 

 such as from one grazing district to another, is recommended, the 

 proposed shift should be shown on the map by arrow lines with 

 figures indicating the number of animals to be moved. Proposed 

 changes in allotment boundaries should be graphically shown if 

 maps are available. Otherwise, written descriptions checked on the 

 ground must be relied upon. 



5. What is the grazing capacity of each range unit for the' class or 

 classes of stock to which the unit is best suited? To what extent is 

 this estimate dependent upon changes in management? Grazing 

 capacity can not ordinarily be determined conclusively in the field, 

 but must be computed later from the figures and notations made on 

 the face of the field map showing the relative stands of forage on 

 the different units and the condition of the range and from avail- 

 able data as to the numbers of stock grazed at present and in the 

 past. 



6. Have adequate salting plans been developed for the Forest or the 

 unit? While the details of salting must be left to the local officers, 

 the inspecting officer should make general recommendations where 

 necessary relative to the total supply of salt, based upon the graz- 

 ing capacity, to be placed on each natural unit. The inspector 

 should also offer any constructive criticisms that might aid the local 

 force in bettering conditions in this respect. 



7. Are the sheep on each allotment managed as they should be? 

 Ordinarily an inspector will not have time to study the manage- 

 ment of each band of sheep, but can gain in the course of inspection 

 a very accurate idea of the methods employed on different parts 

 of the range, and even on particular allotments, by observing the 

 condition of the range with reference to the amount of trampling and 

 the presence of bed grounds. 



8. Is the tree reproduction being injured, and to what extent? 

 The location of any extensive areas where injury has occurred 

 should be indicated on the map, the class or classes of stock responsi- 

 ble being given. The map should be supplemented by notes giving 

 the species and height of trees injured. 



9. Are there any areas on which grazing has caused erosion? 

 Indicate on the map the location of such areas and furnish notes 

 describing the nature and seriousness of the erosion. If practicable, 

 photographs should be taken. 



10. What is the condition of the driveways on the Forest or range 

 unit? Are they located to the best advantage for the protection of 

 the Forest and the interests of the stockmen? Is there an oppor- 

 tunity to establish more driveways and follow some plan of rota- 

 tion in their use? Should present driveways be widened and addi-
