Sanicula bipinnatifida is rela- tively shade-intolerant, occurring on very dry to moderately dry, nitrogen-rich, moder or mull humus form soils (Klinka et al. 1989). Early spring condi- tions are moist, facilitating germination and growth before the onset of summer drought. Specific habi- tats include grass-forb meadow openings in Pseudotsuga menziesii-Aibniws {Arbutus menziesii) forests, Quercus garryana-Arbutus menziesii stands, eroding, sandy banks on seashore cliffs, and shrub- by, grassy knolls. On southeastern Vancouver Island, Sanicula bipinnatifida is mainly a component of the spring flora (April-May), but may persist into late June. Many of the associated species in all sites are introduced. In one instance, S. bipinnatifida was found on a shrubby-grassy knoll dominated by Idaho Fescue (Festuca idahoensis). Common Hawthorn (Crata- egus monogyna), Scotch Broom {Cytisus scoparius), and Kentucky Bluegrass (Poa pratensis), the latter three of which are 51 N • 50 N 49°N 128 W 127 W" 126 W 125 W 124/W / 123 W.
