PRYOR MOUNTAINS DESERT DISTRIBUTION: Phacelia ivesiana is abundant 

 below 1675 m (5500 ft) on the south and west sides of the Pryor Mountains. We located 

 35 mostly large populations in sandy soil in juniper woodlands and associations 

 dominated by Artemisia tridentata , Stipa comata and Bouteloua gracilis . 



MANAGEMENT RECOMMENDATIONS: Phacelia ivesiana is an annual; thus, 

 population sizes may very greatly among years and may respond positively to moderate 

 levels of disturbance. It is common in the study area and should not be given special 

 status on BLM's Miles City District. 



Physaria acutifolia Rydb. 



Southern Twinpod, Rsxlberg Twinpod 



NATURAL HERITAGE PROGRAM STATUS: G5/S3 



MONTANA STATUS: Limited Distribution 



GLOBAL DISTRIBUTION: South-central Montana south to Utah and Colorado 



MONTANA DISTRIBUTION: Southern Carbon County 



PRYOR MOUNTAINS DESERT DISTRIBUTION: Phvsaria acutifolia is common and 

 widespread below 1675 m (5500 ft) on the south and west sides of the Pryor Mountains. 

 This species is sparsely distributed in sandy or sandy clay soils in juniper woodlands, 

 cushion plant grasslands dominated by Au ropyron spicatum and Phlox spp., and 

 shrublands dominated by Artemisia spp. 



MANAGEMENT RECOMMENDATIONS: We located 23 populations of R acutifolia 

 in the study area. Although the plants arc sparsely distributed, the species can be found 

 in almost any community in the study area. Physaria acutifolia should not be given 

 special status on BLM's Miles City District.
