2. State: In South Dakota, this species has a state rank of 

 "SU" (status undetermined) . The records are few while the 

 western South Dakota potential habitat is largely unsurveyed. 



C. Geographical distribution 



1. Species range: Southern 

 Manitoba to Alberta, south to 

 Nevada, and Kansas. There are 

 also records from Idaho, 

 Oregon, Washington and Michigan 

 which are in taxonomic 

 guestion. 



2. South Dakota distribution: 

 Known from at least two 

 collections in Harding County, 

 and in southwestern South 

 Dakota. 



3 . Occurrence in the study 

 area: Efforts to relocate the 

 historic collections in the 

 East Short Pines and Cave Hills 

 were unsuccessful. The Cave 

 Hills specimen (South Dakota 

 State University accession no. 

 3177) was annotated to 

 Chenopodium leptophyllum Nutt. 

 ex Mog. , and the East Short 

 Pines specimen (South Dakota 



State University 3176) was verified. In the East Short Pines 

 unit, the Waddell Gulch area associated with Sand Creek was 

 surveyed extensively. Though there is loose sand habitat 

 eroded out of sandstone, the species does not grow there and 

 the habitat did not seem to be suitably developed. This 

 survey did not cover the Sand Creek and North Sand Creek 

 headwaters which do not appear to have appropriate topographic 

 settings for either dunes or watercourse meanders [on the 

 Moreau Peak 7.5' guad] . For this reason, it is considered 

 unlikely to occur on the District. 



It was collected elsewhere in the county on sand dunes outside 

 of U.S. Forest Service boundaries dissimilar from any part of 

 the District. 



Note: This species is also tracked as a state species of 

 special concern in Montana, but there is unlikely to be 

 suitable habitat on Montana units of the Sioux District.
