EO Number: 
30
EO ID: 
26543
EO History: 
revisit
Population Area: 
5 m sq
More potential habitat to survey: 
yes
Monitoring or research needs for this population: 
Subpoplulations 1 and 2 should be re-visited to evaluate any potential survival that was not observed in this report. The ability of the species to survive a ground level fire (of varying intensity) is not well understood.
Management needs for this population: 
An official trail to the summit of Eightmile Mountain would reduce the haphazard foot traffic that may impact subpopulation 3.
Additional population comments: 
The survey consisted of a thorough area search for all three subpopulations (based upon the 2003 IRPOR description), in addition to reading five (1m2) plot frames within subpopulation 3 (5m2 area) for density and phenology. Density of subpopulation 3 ranged from 1 plant per m2 to 14 plants per m2 (with an average of 5.8 plants per m2). Other potential habitat in the area (open ridgelines and slopes) to the N (0-800m), E (0-20m), S (0-20m), and W (0-20m) of Eightmile Mountain summit was surveyed for individuals. Soils in these areas were generally deeper and less rocky (though well-drained).
