the fecundity of Cirsium longistylum has 

 not been analyzed. Studies involving 

 Carduus nutans have shown that larvae 

 feeding within the receptacle not only 

 consume seed, but also affect the 

 viability of unconsumed seeds (Rees 1977) . 



2. Performance under changed conditions: Not 



known . 



3. Current management policies and actions: 



Current management is the same as outlined 

 under past management. 



4. Future land use: Not known. 

 B. Cultivation. 



1. Controlled propagation techniques: Not known 

 although seeds of C. longistylum germinate 



* - readily without cold stratification or 



scarification (Sarah Mathews, pers. comm.). 



2. Ease of transplanting: Not known. 



3. Pertinent horticultural knowledge: Not 



reviewed. 



4. Status and location of presently cultivated 

 material: 



a. Specimen plants: None known. 



b. Self-sustaining breeding populations: 



None known. 



c. Stored seed: None known. 

 11. Evidence of threats to survival. 



A. Present or threatened destruction, modification, or 

 curtailment of habitat or range: Cirsium 

 longistylum is not currently threatened by habitat 

 alteration, however it should be kept in mind that 

 all of the known occurrences of this species are 

 within a 40 mile radius in the Little Belt 

 Mountains, with a single population in the Big Belt 

 Mountains to the west. 



B. Overutilization for commercial, sporting, 

 scientific, or educational purposes: No threats 

 known .
