Figure 1. Experimental design . (A) Seed source locations (circles) and common garden (squares) of D. californicapopulation locations within the Klamath Mountain (KM), Willamette Valley (WV) and Puget Lowland (PL) ecoregions. (B) Planting design showing alternating square meter grids along transects within naturalD. californica populations at common garden sites. Each square meter grid was composed of 100 cells that were either planted, left as a control for background germination (C), or deemed not suitable for planting (X). See Appendix H Table 5 for site location and environmental data and Appendix A for site photographs.
