 1978 by Bruc3e MoCune (MoCune 1982) , when it was found in the Swan 

 Valley in Missoula County. Further surveys (1983-1986) in the 

 Swan Valley, priiiarily by John Pierce and Peter Lesica, revealed 

 the presence of 15 additional populations, from three sites 

 within the drainage. 



In 1987, the Mcaitana Natural Heritage Program (MUMP) was 

 oOTitracted by the U.S. Fish and Wildlife Service (the Service) , 

 with funds appropriated under Section 6 of the Endangered Species 

 Act, to conduct a status survey of Howell ia aquatilis in Montana 

 (Project Agreement SE-4-P-1) . In June-July 1987, field surveys 

 were conducted by the first author, with assistance from Lisa 

 Canfjbell, Anne Morley, and Peter Lesica; further surveys were 

 also conducted in July 1988. Surveys were conpleted in the Swan 

 and Clearwater River drainages. Lake and Missoula Counties, 

 Mcxitana. Surveys in Idaho were conducted in 1988 by the second 

 author, also under Section 6 ^xsnsorship. 



Of the 16 Montana populations of Howellia aouatilis which were 

 initiadly recorded by the MlimP prior to the start of the 

 surveys, ten of these were monitored during the 1987 surveys; six 

 others were not revisited. Thirty-six new populations were 

 located; collections were made at 18 of these, and the remaining 

 18 were recorded as sight records. In 1988, three additional 

 populations were found, and collections were made from there. In 

 Idaho, one recently observed population was verified, but no new 

 populations were located. All data and photos are frcro 1987 and 

 1988, except where noted.
