Cogswell 1949 Journal 97 3 mi. N Willow Creek, 700 ft., Humboldt Co., Calif. Aug. 29 (cont.) one small stream which disappears into the sand before reaching the river; and just E of the fields + orchard is a bank covered with nearly pure stand of Umbellularia (dense without undergrowth) followed by beyond which are 2 small streams flowing into the river. These streams are bordered by tall Alders in closely spaced woodland formation, with a few Umbellularia admixed. The understory is of Rubus vutifolius and G. [illegible], Symphoricarpus canos sp., Holodiscus discolor, and Ribes sp. A small patch of Douglas Fir occupies the high cut knoll in the area short of a larger plateau-like much dissected river terrace thru which the tiny streams have cut deep, narrow ravines a few hundred yards from the river. Judging from the exposed rock along these ravines the "plateau" is composed of a slate-like rock. The vegetation on this "plateau" is of scattered shrubs of Umbellularia californica, Arctostaphylos manzanita, Rhamnus Californicus, and Ribes sp. (a gooseberry) with the herb cover much less luxuriant than as in the field S. of the woodland area. Associations covered here (all in addition to those listed on p. 93) were, therefore: (4) Weedy fields - dominated by Hypericum perforatum, Circaium sp., and other herbs. (5) Deciduous Shrub Briar Thickets - dominated
