| Comments | Near-monoculture spring 2017 at toe of bank cleared two years ago, probably due to long flooding. Previous spring's creek monkeyflower gone; area also has been weeded extensively for hemlock, nightshade, other common weeds.) Point is approximate; plant also found upstream and downstream but less dense. See 1994 obs. by Barbara Ertter. May become dense in newly disturbed areas, as happened upstream after 1998-99 sewer rebuilding. Calflora |
