Therefore, we do not have the ability to identify these species. There would not be a substantial increase in risk to the species if FY 1999 projects are not surveyed because the riparian buffers in the Aquatic Conservation Strategy provides good protection for the species. Based on the above information, we did not consider it technically feasible to survey for FY 1999 projects and there is no substantial increase in risk if FY 1999 projects are implemented without surveys. The BLM Eugene District disagreed with part of the rationale but agreed that there were problems with the taxonomic description for field identification. The Mount Hood National Forest felt that technical descriptions were sufficient for identification and that their botanists met the requirements for surveyors.
Taxonomic status is uncertain.
Habitat is described as streamside rocks in the splash zone at middle to higher elevations. The known site is in the bed of a fast-flowing, cold, perennial stream at 5410 feet which is shaded by a large mountain hemlock and receives partial sun.
