Observation Narrative ? original plot ID: AA0807, Vegetation type confidence: Mesic tall shrubs dominated by Heteromeles arbutifolia.; Poor lighting - glare from sun, and shadows. Bromus sp seems to carry through most of polygon both in open areas and beneath tall shrubs. Species not mentioned would account for 2-3% additional cover. Mimulus aurantiacus patchy. Heteromeles arbutifolia thoughout most of polygon.;
