Abstract
Since 1937, methods developed by the author have been used successfully to isolate, identify, and germinate seeds of Ribes spp. from samples of duff and soil collected in sugar pine forests. As here described, similar methods were used to show variation in kind and quantity of seeds of many species occurring in soil and duff samples taken from the Stanislaus Experimental Forest, near Pinecrest, Tuolumne County, California.
Timber species found on the sampled areas were sugar pine (Pinus lambertiana Douglas), pondersoa pine (Pinus ponderosa Lawson), Jeffrey pine (Pinus jeffreyi Grey. & Ball.), white fir (Abies concolor (Gord. & Glend.) Hoopes), red fir (Abies magnifica A. Murr.), and incense cedar (Libocedrus decurrens Torrey.)
