ASSESSMENT AND MANAGEMENT RECOMMENDATIONS 



22 







1. THREATS TO CURRENTLY KNOT-fN POPULATIONS: The only two known 

 populations for this species are both on public land: 



001 Bureau of Land Management 



002 U.S. Fish and Wildlife Service 



2. MANAGEMENT PRACTICES AND RESPONSE: The presence of this 

 species in a stock pond (002) raises the possibility that it 

 is associated with disturbance, but this may be refuted by 

 the characterization of the stock pond vegetation as "rich". 



SUMMARY: Round-leaved water-hyssop ( Bacopa rotundif olia ) is a 

 watch species in the Big Dry, Great Falls, and Phillips Resource 

 Areas. It is an aquatic plant that has limited potential habitat 

 on BLM lands in the study area. It has been suggested that it 

 likely to be more common than records indicate elsev/here in the 

 state (Lesica and Shelly 1991) , but this has yet to be 

 corroborated by field information.
