General Management Policy 



corridor should be considered for an Area of 

 Critical Environmental Concern. 



Establishment of Corridors 



The protective corridors should be established 

 by the respective districts through the BLM's land 

 use planning process. They will be established 

 at the discretion of the district managers after full 

 public input. 



Requirements for Corridor Segments 



Lands within the corridor segments should 

 possess a reasonable degree of environmental 

 integrity. The trails themselves should be in a 

 relatively unmodified condition. For the most part 

 they should appear as they may have in the mid- 

 1800s. 



The following define how the protective 

 corridors will be managed. However, final 

 recommendations for mitigating trail impacts will 

 be determined by BLM in consultation with the 

 Advisory Council on Historic Preservation. 



Certified National Historic Trails 



Priority for consideration as protective corridors 

 will be given to the certified segments of the 

 Oregon and Mormon Pioneer National Historic 

 Trails. 



Rights-of-Way 



Right-of-way crossings of the protective 

 corridors may be made. All crossings will be 

 accomplished to minimize surface disturbance in 

 the protective corridor. Crossings will be allowed 

 in areas where trail ruts have been modified by 

 modern uses, where previous crossings exist, or 

 where new corridor crossings would not damage 

 trail remains. All crossings will avoid fragile trail 

 resources. Crossings should be made at right 

 angles to the trail and corridor unless they follow 

 a previous crossing, in which case they may 

 deviate from a right angle. Vegetative species 

 indigenous to the protective corridor will be used 

 to rehabilitate right-of-way related surface 

 disturbance. Any disturbed area will be returned 

 to a natural contour. 



Stipulations will be developed in consultation 

 among the project proponent, adjacent private 

 landowners, and BLM personnel. The stipulations 

 will govern exactly where and how the right-of- 

 way will cross the corridor and how rehabilitation 

 procedures will be used to restore the area. 

 Qualified cultural resource specialists or BLM 

 personnel may be on-site during the construction 

 phase of the project to ensure that the require- 

 ments of the right-of-way permit are met. 



MINERAL MANAGEMENT 



Mineral Leasing 



Fencing 



New fencing projects will cross the trail corridor 

 at right angles to minimize the number of feet 

 per miles of fence within the corridor. Gates and, 

 in some cases, cattleguards will be installed in 

 the fence at trail crossings. Fragile or pristine trail 

 ruts will be avoided with fence crossings. 



The BLM will continue to issue mineral leases 

 on public lands where both the surface and 

 mineral estate are in public ownership. The leases 

 will contain no surface occupancy stipulations to 

 prevent disturbance of trail resources in the 

 corridor. Access to mineral resources such as oil 

 and gas may be available through off-site drilling 

 or directional drilling. 



Range Improvements 



Range improvements in addition to fencing will 

 be considered case-by-case. If environmental 

 analysis indicates that they could be developed 

 in the protective corridor without degrading the 

 trail resources or affecting the trails natural setting 

 (environmental integrity), they will be approved. 

 Location of salt licks and stock reservoirs should 

 be outside the corridor where possible. 



Salable Minerals 



The BLM will continue to consider applications 

 for sand and gravel and other salable minerals 

 in the trail corridor on a case-by-case basis. 

 Approval of applications or the decision to attach 

 special surface protection stipulations will be 

 based on environmental review and analysis of 

 each proposal.
