PRYOR MOUNTAINS DESERT DISTRIBUTION: Camissonia minor is locally 

 common below 1585 m (5200 ft) on the south side of the Pryor Mountains. It generally 

 occurs in moderate-size populations in sandy soil of juniper woodlands or plant 

 associations dominated by Artemisia tridentata . 



MANAGEMENT RECOMMENDATIONS: Camissonia andina is an annual; thus, 

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

 levels of disturbance. This species is common in the study area; we located 17 

 populations. This species should not be given special status on BLM's Miles City 

 District. 



Camissonia parvula (Nuttall) Raven 



Small Evening-primrose 



NATURAL HERITAGE PROGRAM STATUS: G5/S1 



MONTANA STATUS: None 



GLOBAL DISTRIBUTION: Eastern Washington to south-central Montana, south to 

 California, Nevada and Colorado 



MONTANA DISTRIBUTION: Southern Carbon County 



PRYOR MOUNTAINS DESERT DISTRIBUTION: Two small populations of 

 Camissonia parvula were located at the southern foot of the Pryor Mountains between 

 1585 and 1675 m (5200 and 5500 ft). It occurs in sandy soil weathered from calcareous 

 sandstone and is associated with ecotonal areas between juniper woodland and sagebrush 

 steppe. 



MANAGEMENT RECOMMENDATIONS: Camissonia parvula is an annual; thus, 

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

 levels of disturbance. This species was first discovered in Montana during the course of 

 this study. It is rare in the study area and should be given special status on BLM's Miles 

 City District.
