Misc Fields: 
Observation Narrative ? original plot ID: AA1221, Vegetation type confidence: Only trees assessed. All assessed except northern tip. High certainty for tree layer. More Juglans californica in southern 1/2. All diagnostics throughout. Can't assess shrub layer well because obstructed by canopy. Possibly associated. Ceanothus spinosus within polygon - difficult to assess actual cover. No type in key that matches type. 1453 best then alliance for current types. Juglans californica definitely associated, Salix, Quercu too weak to be associated.;
