2. General demographic details (Montana): 



a. EO#001 



1. Area occupied by population: Less than 1 acre. 



2. Estimated number of individuals: Over 100+ plants have 

 een noted in the course of two years of observation and two 

 years of monitoring. Peak flowering stem count was 71 in 

 1994. The demographic monitoring was set up at this site in 

 1996 (Appendix D). 



3. Density: Sparse. The entire population fits within an area that 

 is app. 25 X 35 m. 



4. Presence of dispersed seeds: Capsules were maturing at the 

 time of monitoring but none had begun to dehisce (24 August 

 1996 and 4 September 1997). Undehisced capsules were 

 observed in November of 1997. 



5. Evidence of reproduction: NA 



6. Evidence of population expansion or decline: None 



b. EO#002 



1. Area occupied by population: Less than 1 acre. 



2. Estimated number of individuals: Only 1 plant could be 

 found in four hours of searching. There are likely to be other 

 plants at least in nonflowering state, but this is the smallest of 

 occurrences. 



3. Density: NA 



4. Presence of dispersed seeds: NA 



5. Evidence of reproduction: NA 



6. Evidence of population expansion or decline: The 

 valleybottom condition reflects past habitat degradation. 



c EO#003 - MERGED WITH EO#004 



AND DELETED AS SEPARATE RECORD 



d. EO#004 



1. Area occupied by population: This area has high 

 microhabitat diversity and the most extensive population by 

 far. It spans four sections, though the extent of occupied 

 habitat is probably less than 10 acres. 



2. Estimated number of individuals: This area had 58 

 flowering plants in 1996 based on over seven miles of 

 walking. Additional areas with about 30 plants were 

 documented in 1997. This is probably low relative to the total 

 population nvmibers for any given year. 



3. Density: Sparse. There are few places where more than ten
