Germination and Growth of Douglas-Fir and Incense-Cedar Seedlings on Two Southwestern Oregon Soils

Douglas-fir and incense-cedar seeds were germinated and grown for 18 months with and without grass competition on soils derived from pillow basalt and marine sandstone. Grass reduced Douglas-fir germination on the basalt soil. Douglas-fir seedlings were heavier than incense-cedar seedlings on basalt soil where grass was absent, but incense-cedars were heavier than Douglas-firs on all other soil-grass combinations.
