population monitoring studies are 

 recommended, in order to more accurately 

 assess trends at the known sites. Also, the 

 observed genetic differentiation among five 

 of the seven known populations increases the 

 importance of protection of all known sites, 

 in order to preserve the full range of 

 genetic adaptation possessed by the taxon 

 (Wolf 1988; see Appendix B, p. 38). 



II.13.B. Recommendations to other U.S. federal 



agencies: Claytonia lanceolata var. f lava 

 has been placed on the list of sensitive 

 plant species in Region 1 of the U.S. Forest 

 Service; it is recommended that it be 

 retained on this list. 



II. 14. A. Recommended critical habitat: Critical 

 habitat is not being recommended at this 

 time, as the taxon should be retained in 

 Category 2 pending monitoring studies and 

 final publication of its systematic status. 



II. 15. A. Conservation/recovery recommendations: The 



following recommendations have been made to 

 the U.S. Forest Service (Shelly 1989) : 



1. Protection of natural habitats which 

 currentlv support populations. All known 

 populations occur, wholly or partially, on 

 U.S. Forest Service lands. They should be 

 considered in any habitat alteration projects 

 that may occur in their vicinity. If 

 disturbance is proposed within or near the 

 population areas, detailed surveys should be 

 conducted, and mitigation measures developed 

 to reduce or eliminate project impacts. The 

 most likely impacts may be from increased 

 mining activity in the Vipond Park area in 

 the Pioneer Mountains. 



It should be noted that the electrophoretic 

 analysis revealed genetic differentiation 

 among populations of C. lanceolata var. flava 

 (see Appendix B, p. 38) . Thus, it will be 

 important to maintain all known populations, 

 in order to protect the full range of genetic 

 variation within the taxon. 



2 . Notification of weed control and road 



maintenance crews, range conservationists, 

 and all other appropriate U.S. Forest Service 

 personnel, of population locations. Maps 

 detailing the site locations should be
