represent populations occurring on Gallatin 

 National Forest lands. It is believed that the 

 site of the original Grayling Creek population was 

 rediscovered in the July 1989 survey. A second 

 historical site was recorded in the Gallatin Canyon 

 at "Daly Creek." There is a Dailey Creek joining 

 the Gallatin River on Yellowstone Park lands. The 

 lands to the west of the river in this vicinity are 

 State of Montana lands (Gallatin Wildlife 

 Management Area) or Gallatin National Forest lands. 

 No populations of C. qracillima were located in 

 this area, on Forest, State or Park lands. The 

 site is represented by a poor specimen of uncertain 

 identification (RM #70471) . Descriptive data for 

 the historical site ("10% east slope. Shallow 

 coarse soil. Woodland.") is not characteristic of 

 sites where C. qracillima is found. 



4. AREAS SURVEYED BUT TAXON NOT LOCATED: Suitable 

 habitat along the Gallatin River, from the 

 Yellowstone National Park boundary to Big Sky, was 

 surveyed for Castilleja qracillima . The population 

 near Snowflake Springs (007) was the only one 

 located along the Gallatin River outside 

 Yellowstone National Park. 



E. HABITAT
