Immediate edge of reservoir. ¶Associates: Salix exigua is the only common obligated riparian woody plant.¶Exposure: W. ¶Abundance (1-5): 2. ¶Soil: Basaltic. ¶Adjacent slopes are degraded Artemisia tridentata/grass, with escaped Prunus dulcis widely scattered. Height: 30'. ¶D. B. H.: 8". ¶Mature and juvenile branch leaves. ¶This tree is spreading along the reservoir edge for a distance of about 2 miles. While some are clonal clumps, young trees also appear in isolated places along the edge where the substrate is shear rock. Thus it appears that branches break off, (or are cut off by recreationists) float and become rooted. Phenology: Vegetative.
