Results 



Range and representative habitats of the two Sensitive lady's slippper species on the KNF were 

 circumscribed, population and habitat trends were documented, and their status was put into a 

 state context augmented by the few new occurrences that were found. I discovered one new 

 population of Cypripedium calceolus var. parviflorum in an unnamed drainage southeast of 

 Libby Dam, and one new occurrence of C passerinum at Brimstone Creek where Q calceolus 

 var. parviflorum was previously known. Forest botanists from the Fortine Ranger District, Jack 

 Triepke and Tobias Spribille, found four additional populations of C. calceolus var. parviflorum 

 along Lime and Murphy Creeks, near Dickey Lake, and in the foothills of the Whitefish Range 

 above Glen Lake. T. Spribille also found an occurrence of C. passerinum along Magnesia Creek. 

 In addition, one population of C. calceolus var. parviflorum on Army Corps of Engineers land 

 near Libby Dam which was known by local individuals was verified. Several known populations 

 of undetermined Cypripedium species were relocated and were found to be the relatively 

 common C. montanum . There are now fifteen populations of C. calceolus var. parviflorum and 

 six known populations of C_. passerinum on the KNF (Table 1). Cypripedium fasciculatum has 

 not been found on the Forest. 



The Status Reviews for each of the two Sensitive Cypripedium species which follow this section 

 elaborate the results of the surveys and provide pertinent information from other sources. 

 Included are sections on classification, pending taxonomic changes, formal status, description, 

 geographical distribution, habitat, population demography and biology, land ownership, and 

 management considerations. Throughout the remainder of this report occurrences of Sensitive 

 lady's slippers are referred to by their site names and three digit element occurrence numbers 

 assigned in the Biological Conservation Database. Element Occurrence Records and 

 topographic maps showing the precise location of each population are given in Appendix A. 

 ECODATA forms are included in Appendix B and photographic slides of the plants and their 

 habitats are attached as Appendix C.
