Movement / Home Range
This species is endemic to northern Douglas County, Oregon in the interior Umpqua River watershed at elevations from 100 to 230 m (328 to 755 feet). The species was collected only four times between 1887 and 1961, only within Douglas County (Currin et. al 2005). The taxon was considered possibly extinct (Meinke 1982) until it was rediscovered in 1983 as a result of intensive field surveys (J. Kagan, pers. comm. 1997). At the time of final listing (64 FR 1515), P. hirtus was known from 17 habitat patches and two experimentally established populations. These habitat patches occurred in 8 extant Element Occurrences (EOs) at that time.
Reproductive Strategy
An annual that can be facultatively perennial. It always reproduces in the first year.
