Location Narrative ? This is a lower slope, general gradual grade surrounding smaller drainage. As slope steepens out of this polygon, scrub oak is absent. Certain ID on Salix species. Fairly diverse. Several more species than indicated. Slight aspect only. Mostly slightly concave. Ceanothus megacarpus-Adenostoma fasciculatum Association to south, NE part should be with this polygon. Juglans californica foliage is full. One of the Inclusions is an interesting mix of native/non-natives on bench above small drainage.
