Haymaker Canyon 



Roe, L.S. (449-1,2), 1991, (MONT). Specimen 449-2 

 showed characters intermediate to A. brevistvla 

 and A. flavescens . 



2. SLIDES: Color slides of individuals, populations, 

 and the habitat of A. brevistvla are deposited at' 

 the Montana Natural Heritage Program, 1515 E. 6th 

 Ave. , Helena, MT. 



III. ASSESSMENT AND MANAGEMENT RECOMMENDATIONS 



A. THREATS TO CURRENTLY KNOWN POPULATIONS: 



1. GRAZING: The Sage Creek (003) and Dry Pole (001) 

 populations are in grazing allotments. Grazing 

 impacts should be evaluated, especially for the 

 Sage Creek area where much of the forage burned. 

 This site was rested during 1991, but will be 

 grazed at the previous level in 1992. The effects 

 of grazing should be noted where possible. 



2. TIMBER HARVESTING: As stated above, although 

 precautions may be taken, timber harvest is likely 

 to affect a portion of the remaining plants at 

 Sage Creek (003). Aquileqia brevistvla also 

 occurs in several areas proposed for timber sale 

 along the South Fork of the Judith River, and 

 these activities should be reviewed for their 

 effect on these populations. 



3. WEED CONTROL ACTIVITIES: Many of the A. 

 brevistyla populations would be susceptible to 

 weed control activities due to their proximity to 

 roadways. Weed control management teams should be 

 aware of the presence of A. brevistvla populations 

 on the Lewis & Clark National Forest. 



4. ROAD BUILDING: Aquileqia brevistvla plants have 

 been found to invade old road cuts in both Hay 

 Canyon (007) and Burley Creek (005). Although 

 disturbance does not appear to be necessary for 

 this species' survival, A. brevistvla does appear 

 able to invade and establish itself in disturbed 

 areas. if this species is able to invade 

 disturbed areas, skid trails and roads used in
