General Management Policy 



Locatable Minerals 



INVENTORY REQUIREMENTS 



The portions of the protective corridor that are 

 presently withdrawn from mineral location will 

 continue under present management. Those 

 portions presently open to location will be 

 managed under the BLM's surface management 

 regulations governing exploration and develop- 

 ment. Plans of operations requirements may be 

 instituted on sensitive trail segments and sites if 

 necessary to protect significant trail resources, 

 see Code of Federal Regulations, Title 43, 3809.1- 

 4. Any future modifications of the present 

 withdrawal status will be considered in the 

 respective district's resource management plans. 



1. All previously unsurveyed segments of the 

 trails will require intensive inventory prior to 

 authorization of any action which might 

 adversely affect the trails. 



2. BLM's policies and procedures for inventory 

 are delineated in the Bureau's 8143 manual, 

 as well as NTL 85-1 . See Appendix III. 



3. No intensive inventories will be required on 

 those areas which have already been 

 adequately surveyed. 



Valid Existing Rights 



The BLM will recognize all valid existing rights 

 in the protective corridors. Examples of valid 

 existing rights are existing oil and gas leases. 



TRAIL MARKING 



The BLM will adopt a uniform system to mark 

 the trails statewide on public lands. The marking 

 program will include the five actions listed below. 



1. Trail ruts and segments will be marked with 

 6" X 6" x 6' treated wooden signposts with 

 routed names on the sides (see Figures 1 and 

 2). The posts will be treated to retard decay. 

 2. Major road crossings of the trails may be 

 marked with trail signs identifying the trail 

 (see Figures 3 and 4). 



3. Signs will be labeled with standard BLM signs 

 showing legal description of sign location. 

 BLM sign S-8 will be used (see Figure 5). 



4. Trail posts will be located every mile, or a 

 distance determined to be appropriate by the 

 individual area managers. 



5. An inventory of the signs will be maintained. 

 Annual field checks will be conducted and 

 missing or damaged signs will be replaced. 

 Signs will be supplied by the National Park 

 Service or the BLM Rawlins sign shop. 



NATIONAL REGISTER OF 

 HISTORIC PLACES 



Selected sites and segments of the Historic 

 Trails may, from time to time, be nominated to 

 the National Register of Historic Places. All 

 agencies involved with management of the trail 

 resources (BLM, U.S. Fish and Wildlife Service, 

 U.S. Forest Service, National Park Service, State 

 of Wyoming) have agreed to cooperate in the 

 development of a thematic nomination for the 

 Oregon and Mormon Trail routes across 

 Wyoming. The Wyoming State Historic 

 Preservation Officer has completed the draft 

 Statement of Significance. Individual site and 

 segment nominations will be done at the 

 discretion of the individual district managers. 



Subsequent nominations would be made as 

 needed for selected sites or trail segments. 



MONITORING AND USE 

 SUPERVISION 



The BLM will implement a monitoring and use 

 supervision program on the trails. It will consist 

 of the following: 



1. Monitoring recreational use through the use 

 of volunteers or seasonal employees patrol- 

 ling trails and historic sites. This may include 

 visitor contact and live interpretation as time 

 and budget permit;
