  • ·         Coast populations get about 52-74 cm of rain a year (Kaye, 2011)
  • ·         Mainland population gets about 129 cm of rain a year (Kaye, 2011)
  • ·         Extinct Willamette Valley population was on non-glacial well-drained soil (Kaye, 2011)
  • ·         Extinct Willamette Valley population had about 104-123 cm of rain (Kaye, 2011)

    This information leaves the reader wanting. Is this all of the information relevant to the habitat? Can you talk about how the habitat of the extinct population compared to that of preferred habitat. It seems as though the rainfall amount was right, but the plant still went extinct. Was this because the soil was non-glacial?
