range of six populations was extended. Exact 

 locations of the recorded C. longistylum 

 populations are provided on USGS quadrangle 

 maps in Appendix A, pp. 57-77, along with 

 element occurrence records (pp. 36-56) for each 

 population. Cirsium longistylum is nearly 

 ubiquitous to many of the meadows and roadsides 

 at higher elevations in the Little Belt 

 Mountains, and is common in moist streamside 

 meadows at lower elevations. The populations 

 mapped do not represent all of the populations 

 observed to be present in the Little Belt 

 Mountains. 



2. Populations known or assumed extirpated. 

 a. Montana: None. 



3. Historically known populations where current 

 status is not known: 



a. Montana: Two sites are considered as 

 historic locations for populations of 

 Cirsium longistylum . The first known 

 collection for this species at Long Baldy 

 (009) has not been resurveyed. The Forest 

 Green (003) site was resurveyed in 1983 by 

 Ramstetter, but "no plants which could 

 conclusively be identified as C. 

 longistylum were located," 



4. Locations not yet investigated believed likely 

 to support additional natural populations. 



Although there are no records for this species 

 in the Snowy Range there is potential habitat 

 in the area. 



5. Reports having ambiguous or incomplete locality 

 information: 



a. Montana: The voucher specimen for the 



Long Baldy (009) site states "Long Baldy, 

 Judith Basin County." Big Baldy Mountain 

 lies in Judith Basin County, while Long 

 Mountain and Neihart Baldy peaks lie to 

 the east in Cascade County. The actual 

 collection site may lie along the ridge 

 between the peaks.
